Smoked Sweet Potatoes with Maple Bourbon Butter — The Showstopping Side Dish That Steals the Whole Cookout

Spread the love

Imagine pulling four perfectly smoked sweet potatoes off the grill, splitting them open with a quick slice, and watching a generous pat of maple bourbon butter melt slowly down into the soft, smoky, caramelized flesh beneath it — the steam carrying this incredible smell of hickory smoke, warm bourbon, and sweet maple syrup that stops every single person in the backyard mid-conversation. That is what these smoked sweet potatoes with maple bourbon butter do, every single time, without fail. They are the side dish that makes people completely forget about the main course.

Be honest — how many times have you shown up to a cookout and seen the same tired baked potato bar, the same coleslaw, the same corn on the cob? Nothing wrong with any of that, but when was the last time a side dish genuinely made the whole table stop and talk? These smoked sweet potatoes are different. They look dramatic, they smell incredible, and that first bite — soft and pillowy on the inside, with a thin, smoky skin on the outside and that rich, buttery, boozy glaze soaking into every bite — is something people remember long after the cookout is over.

Whether you are firing up the smoker for a Thanksgiving cookout, a fall tailgate, a summer backyard BBQ, or just a Sunday afternoon where you want to do something a little more special than usual, this recipe belongs on your grill. Keep reading — I am sharing the complete method, the maple bourbon butter recipe that people beg me for every time I make it, and every tip I have learned to make this foolproof on any smoker or grill you own.

Why This Recipe Works

Sweet potatoes and smoke were made for each other — here is exactly why this recipe delivers every single time:

✔ The low-and-slow smoke penetrates the natural sugars in the sweet potato and caramelizes them from the inside out, creating a depth of flavor that a regular oven simply cannot touch
✔ The maple bourbon butter is a five-ingredient compound butter that comes together in five minutes flat and makes everything it touches taste like a million dollars
✔ Hands-off cooking — once the potatoes are on the smoker, you have 90 minutes to do whatever you want while the grill does all the heavy lifting
✔ Naturally gluten-free and vegetarian — a crowd-pleasing side that works for nearly every guest at the table without any modifications
✔ Incredibly versatile — pairs beautifully with smoked brisket, pulled pork, grilled chicken, or as a standalone vegetarian centerpiece
✔ Budget-friendly and feeds a crowd — sweet potatoes cost almost nothing and one recipe easily scales up for a big gathering
✔ Works on any smoker, charcoal grill, pellet grill, or gas grill with a few simple adjustments — no specialized equipment required

The maple bourbon butter is the thing that takes this from great to genuinely unforgettable — and once you read what goes into it, you are going to want to put it on absolutely everything. Let’s get into it.

What You’ll Need

Simple, honest, deeply flavored ingredients — this is comfort food dressed up in its Sunday best.

For the Smoked Sweet Potatoes

4 large sweet potatoes, roughly equal in size (about 8–10 oz each)
2 tablespoons olive oil or vegetable oil
1 teaspoon kosher salt
½ teaspoon black pepper, freshly ground
½ teaspoon smoked paprika (optional — deepens the smoky crust on the skin)

For the Maple Bourbon Butter

8 tablespoons (1 stick) unsalted butter, softened to room temperature
3 tablespoons pure maple syrup — always real, never pancake syrup
2 tablespoons bourbon (a good everyday pour like Maker’s Mark or Bulleit works perfectly)
½ teaspoon ground cinnamon
¼ teaspoon ground nutmeg
¼ teaspoon kosher salt
Pinch of cayenne pepper (optional — just enough to add a whisper of warmth in the background)

For Serving and Garnish

Flaky sea salt (Maldon is the gold standard) for finishing
Fresh thyme sprigs or rosemary for a fragrant, beautiful garnish
Toasted pecans, roughly chopped — adds crunch and a nutty sweetness that is outstanding here
A drizzle of extra maple syrup for the table
Crumbled goat cheese or feta for a creamy, tangy contrast (optional but stunning)

Wood for Smoking

Apple wood or cherry wood chips or chunks — sweet, mild fruitwood smoke complements the natural sweetness of the potato beautifully
Pecan wood is another excellent choice and leans into the nutty, warm flavor profile of the bourbon butter
Hickory works too if that is what you have on hand — use it more sparingly since it is stronger and can overpower the delicate sweetness if you go too heavy

Substitutions

Not cooking with bourbon or serving to kids? Swap the bourbon in the compound butter for 1 tablespoon of pure vanilla extract plus 1 tablespoon of apple juice or apple cider. You keep all the warm, aromatic, complex flavor without any alcohol — and nobody at the table will know the difference. The butter is still absolutely spectacular.

No smoker or charcoal grill? A gas grill works perfectly with a smoker box or a foil pouch of wood chips placed directly over the lit burner. You can also make these in the oven at 400°F for 50 to 60 minutes — you will not get the deep smoke ring, but the maple bourbon butter makes them extraordinary regardless of how they are cooked.

Want to make the butter dairy-free? A good quality vegan butter like Miyoko’s or Earth Balance works as a one-to-one swap. The compound butter will be slightly softer in texture but every bit as rich and delicious in flavor.

🧑‍🍳 Chef’s Note — Real Maple Syrup: This is the one ingredient where quality genuinely makes a significant, obvious, undeniable difference. Real Grade A dark maple syrup has a deep, rich, complex caramel flavor that is worlds apart from pancake-style corn syrup blends. In a recipe this simple where maple is a starring flavor, use the real thing. The cost difference is a few dollars and the taste difference is enormous.

🧑‍🍳 Chef’s Note — Sweet Potato Size: Try to pick sweet potatoes that are as close to the same size and shape as possible — roughly 8 to 10 ounces each and relatively uniform in diameter. This ensures they all finish cooking at the same time. Wildly different sizes means some will be done while others still need more time, which creates an uneven result at the table.

How to Make Smoked Sweet Potatoes with Maple Bourbon Butter — Step by Step

Make the maple bourbon butter first. In a medium bowl, combine the softened butter, maple syrup, bourbon, cinnamon, nutmeg, salt, and cayenne if using. Beat everything together with a fork or hand mixer until completely smooth, fluffy, and fully combined. Taste it — it should be rich, sweet, warm, and deeply aromatic with a gentle bourbon finish. Lay a sheet of plastic wrap flat on the counter, spoon the butter down the center in a rough log shape, roll it up tightly into a cylinder, and twist the ends closed. Refrigerate for at least 30 minutes to firm up. The butter keeps in the fridge for up to 2 weeks and in the freezer for up to 3 months.
Prep the sweet potatoes. Scrub each sweet potato thoroughly under cold running water — you are eating the skin and it picks up beautiful smoke flavor, so you want it clean. Pat them completely dry with paper towels. Using a fork or skewer, pierce each potato all over, about 8 to 10 times per potato. This allows steam to escape during cooking and prevents the skin from splitting or bursting on the smoker. Rub each potato all over with oil, then season generously with kosher salt, black pepper, and smoked paprika if using.
Set up your smoker or grill. Preheat your smoker or grill to a steady 250°F for a low-and-slow cook, or 275°F if you want to push it slightly faster without sacrificing much smoke penetration. Add your wood — apple, cherry, or pecan chunks for a stick burner or offset smoker; chips in a smoker box or foil pouch for a gas or pellet grill. You want a clean, thin blue smoke, not a thick, billowing white smoke, which can make the potatoes taste bitter and acrid.
Smoke the sweet potatoes. Place the prepped sweet potatoes directly on the smoker grate, leaving at least 2 inches of space between each one for airflow and even smoke circulation. Close the lid and smoke at 250°F for 90 minutes to 2 hours, depending on the size of your potatoes. Resist the urge to open the smoker every 20 minutes — every time the lid comes off, the temperature drops and clean smoke is lost. One check at the 75-minute mark is plenty.
Test for doneness. The sweet potatoes are ready when a fork or thin skewer slides into the thickest part of the potato with absolutely zero resistance — it should feel like pushing through soft butter. The skin will be slightly wrinkled, deeply bronzed, and fragrant with smoke. The exterior of particularly large potatoes may feel slightly firm to the touch but collapse immediately when pressed — that is exactly right. If there is any resistance at all when you probe them, give them another 15 to 20 minutes and check again.
Rest briefly and split open. Transfer the smoked sweet potatoes to a cutting board and let them rest for 5 minutes — they are extremely hot all the way through and the interior needs a moment to settle. Using a sharp knife, cut a deep lengthwise slit down the center of each potato, then use your thumbs to push both ends gently toward the center so the potato opens up wide into a generous, fluffy mound of bright orange interior flesh.
Add the maple bourbon butter and serve. Cut two generous rounds from the chilled butter log and place them directly in the center of each split potato. Watch them melt and pool into the steaming flesh — the maple syrup runs in rivulets into the potato, the bourbon perfumes the air, and the cinnamon and nutmeg bloom beautifully in the heat. Finish with a pinch of flaky sea salt, a few toasted pecans, a sprig of fresh thyme, and an extra drizzle of maple syrup if you are feeling generous. Serve immediately while the butter is still melting and the steam is still rising.

That is a side dish worth talking about — and now let’s make sure you know exactly how to serve it for maximum impact at the table.

How to Serve It

These smoked sweet potatoes with maple bourbon butter are incredibly versatile and work beautifully at everything from backyard cookouts to holiday tables:

🍂 Thanksgiving or Friendsgiving cookout: Serve these alongside smoked turkey, cranberry sauce, and cornbread stuffing for a Thanksgiving spread that is entirely cooked on the smoker. They replace the traditional sweet potato casserole with something more sophisticated, deeply smoky, and completely unforgettable — and they free up precious oven space on the busiest cooking day of the year.
🥩 Alongside smoked brisket or pulled pork: The sweetness and richness of the maple bourbon butter is the perfect counterpoint to the savory, smoky, peppery bark of a brisket or the tangy vinegar of pulled pork. This pairing is absolute backyard BBQ perfection — the kind of plate that photographs beautifully and tastes even better than it looks.
🏈 Fall tailgate or game day spread: Set out the smoked sweet potatoes with all the toppings in little bowls alongside the butter — pecans, goat cheese, extra maple syrup, bacon crumbles, fresh thyme — and let everyone customize their own loaded potato. It is an interactive, impressive spread that feels a cut above the usual game day food and generates serious conversation.
🌿 Vegetarian or holiday dinner centerpiece: Double the recipe and serve these as the main event for a vegetarian holiday dinner, topped generously with the maple bourbon butter, goat cheese, candied pecans, dried cranberries, and fresh herbs. They are substantial, beautiful, and satisfying enough to be the star of the plate without any meat required.
🥗 Weeknight dinner side dish: These pair wonderfully with simple weeknight proteins — roasted chicken thighs, pan-seared pork chops, or a simple grilled salmon fillet. You can even skip the smoker on busy nights and roast them in the oven at 400°F — the maple bourbon butter makes them spectacular regardless of the cooking method.

However you serve them, have the extra maple bourbon butter on the table — because someone will absolutely ask for more, and you want to be ready.

Storage & Leftovers

Smoked sweet potatoes — Refrigerator: Store leftover smoked sweet potatoes in an airtight container or wrapped tightly in foil in the fridge for up to 5 days. The smoke flavor actually deepens and mellows beautifully overnight — day-two leftovers are genuinely outstanding. Store them whole or already split, but always keep the butter separate so it does not absorb into the cold potato and disappear.

Smoked sweet potatoes — Freezer: Cooked smoked sweet potatoes freeze well for up to 3 months. Let them cool completely, wrap each one tightly in foil, then place in a zip-lock freezer bag and press out all the air. Thaw overnight in the fridge before reheating. The texture softens slightly but the smoky flavor holds up beautifully through the freeze-thaw cycle.

Maple bourbon butter — Refrigerator: The compound butter keeps in the fridge for up to 2 weeks wrapped tightly in plastic wrap or stored in an airtight jar. Slice off rounds as needed directly from the chilled log.

Maple bourbon butter — Freezer: The butter freezes perfectly for up to 3 months. Wrap the log tightly in plastic wrap, then in foil, and freeze. Slice off rounds directly from frozen — they thaw at room temperature in about 10 minutes or melt instantly on hot food straight from the freezer.

📅 Make-Ahead Tip: This is one of the best make-ahead side dishes in your entire recipe arsenal. Smoke the sweet potatoes up to 3 days in advance and refrigerate them whole and uncut. Make the maple bourbon butter up to 2 weeks ahead. When it is time to serve, reheat the potatoes in a 350°F oven for 20 to 25 minutes until steaming hot all the way through, split them open, and add the butter fresh. The whole thing looks and tastes like you made it minutes ago — absolutely nobody will ever know it was prepped days in advance. This is the move for holiday entertaining.

Reheating (Oven — Best Method): Wrap each potato in foil and reheat in a 350°F oven for 20 to 25 minutes until heated all the way through. Remove foil for the last 5 minutes to re-crisp the skin. This method keeps the interior perfectly fluffy and moist without drying it out.

Reheating (Microwave — Quick Option): Place the potato on a microwave-safe plate and heat on HIGH for 2 to 3 minutes, flipping once halfway through, until steaming hot in the center. The skin will not be crispy but the interior will be hot and fluffy. Add the maple bourbon butter immediately after so it melts into the hot flesh — quick, easy, and still delicious for a weekday lunch.

Helpful Tips & Common Mistakes

A few small adjustments make the difference between good smoked sweet potatoes and truly great ones. Here is what to watch for:

✗ Mistake: Using thick, billowing white smoke instead of thin blue smoke.
✓ Fix: White smoke means the wood is smoldering inefficiently and it will coat your food with a harsh, bitter, acrid flavor that no amount of maple bourbon butter can fix. You want thin, almost invisible blue smoke — this is clean smoke that adds flavor without overpowering. Get your fire burning properly and your wood fully lit before putting the potatoes on. Patience at the start pays off in the flavor at the end.

✗ Mistake: Not piercing the sweet potatoes before smoking.
✓ Fix: Always pierce each potato 8 to 10 times with a fork or skewer before it goes on the smoker. Steam builds up inside as the potato cooks and needs a way to escape. Skip this step and you risk the potato splitting or even bursting open on the grate — which is messy, wastes good food, and can cause a flare-up inside the smoker.

✗ Mistake: Opening the smoker lid every 20 to 30 minutes to check on things.
✓ Fix: Every time the lid opens, the temperature inside drops significantly and precious clean smoke escapes. These sweet potatoes are completely forgiving — set them on the grate, close the lid, maintain your target temperature, and do not open it until the 75-minute mark. One check is all you need. Trust the process and the smoker.

✗ Mistake: Using cold butter straight from the fridge on the hot potato.
✓ Fix: The compound butter should be cold enough to hold its shape when you slice it — but not so rock-hard that it sits on top of the potato without melting. Pull the butter out of the fridge 5 to 10 minutes before serving. Perfectly chilled but not frozen means it melts slowly and beautifully into the hot interior rather than either refusing to melt or dissolving into a greasy puddle instantly.

✗ Mistake: Skipping the flaky sea salt finish.
✓ Fix: A generous pinch of flaky sea salt over the finished potato is not optional — it is the element that ties everything together. The contrast of that sharp, crystalline salt against the sweet maple, warm bourbon, and smoky potato is what makes every single bite feel perfectly balanced rather than cloying or one-dimensional. Never skip the finishing salt.

Recipe Variations

The classic recipe is outstanding as written, but these four twists are absolutely worth exploring:

🥓 Loaded Smoked Sweet Potatoes: Top the finished potatoes with crumbled crispy bacon, a generous dollop of sour cream, shredded sharp cheddar, sliced green onions, and the maple bourbon butter. This is the sweet-and-savory loaded potato that absolutely nobody can resist — it hits every flavor note simultaneously and makes for one of the most satisfying, hearty side dishes imaginable. A guaranteed crowd-pleaser at every cookout and tailgate without exception.

🌶️ Spicy Chipotle Maple Butter Version: Add 1 teaspoon of chipotle powder and 1 tablespoon of adobo sauce from a can of chipotle peppers to the compound butter in place of the cinnamon and nutmeg. The result is smoky, spicy, sweet, and deeply complex — a butter that plays off the natural sweetness of the potato with serious heat and bold Southwest flavor. This version is absolutely electric alongside smoked brisket or pulled pork.

🧀 Goat Cheese and Candied Pecan Version: Finish each potato with the maple bourbon butter, a generous crumble of creamy goat cheese, a handful of homemade candied pecans, dried cranberries, and a drizzle of raw honey. This is the elegant, dinner-party version of this recipe — sophisticated, beautifully composed, and impressive enough to serve at a holiday table without any additional preparation. The tangy goat cheese against the sweet butter and smoky potato is a combination that is genuinely hard to stop eating.

🫙 Oven-Roasted Version for Year-Round Cooking: Preheat your oven to 400°F. Prep the sweet potatoes exactly as written — pierced, oiled, and seasoned. Place on a foil-lined baking sheet and roast for 50 to 60 minutes until completely tender. For a smoky element without the smoker, add ½ teaspoon of liquid smoke to the compound butter and use extra smoked paprika on the skin before roasting. The maple bourbon butter makes these absolutely spectacular regardless of how the potato was cooked — this version is a perfect weeknight dinner option all fall and winter long.

Frequently Asked Questions

What temperature do you smoke sweet potatoes at?

The sweet spot is 250°F to 275°F for low-and-slow smoking that gives the smoke maximum time to penetrate the potato and caramelize the natural sugars from the inside out. At 250°F, plan on 90 minutes to 2 hours depending on the size of your potatoes. You can push the temperature up to 300°F if you are short on time — the potatoes will be done in about 60 to 75 minutes, though you will get slightly less smoke penetration compared to the lower temperature.

What wood is best for smoking sweet potatoes?

Apple wood and cherry wood are the top recommendations — both are mild, slightly sweet fruitwoods that complement the natural sweetness of the potato without overpowering it. Pecan is an excellent choice that ties in beautifully with the nutty bourbon notes in the butter. Hickory works in a pinch but use it sparingly since it is significantly stronger and can make the potatoes taste bitter and over-smoked if you go heavy. Avoid mesquite for this recipe — it is far too bold and aggressive for something as delicate as a sweet potato.

Can I make smoked sweet potatoes without a smoker?

Absolutely. On a gas grill, place a foil pouch of soaked wood chips or a stainless steel smoker box directly over one of the lit burners, turn the other burners to medium, and put the sweet potatoes on the cool side over indirect heat. Keep the lid closed and maintain a temperature of 300°F to 350°F for 60 to 75 minutes. In the oven, roast at 400°F for 50 to 60 minutes and add a small amount of liquid smoke to the compound butter to approximate that smoky quality. The maple bourbon butter makes the potatoes spectacular with either method.

Can I make the maple bourbon butter ahead of time?

Yes — and you should. The compound butter actually improves after resting in the fridge as the flavors meld together and deepen. Make it up to 2 weeks in advance and store the rolled log in the fridge wrapped tightly in plastic wrap. It also freezes beautifully for up to 3 months. Having a log of this butter ready in your fridge or freezer is one of the smartest things you can do as a home cook — it transforms simple weeknight dishes into something genuinely special with zero effort.

Can I use yams instead of sweet potatoes?

In most American grocery stores, what is labeled as a “yam” is actually a variety of sweet potato — so yes, anything in that orange-fleshed family works beautifully here. True yams (the dry, starchy variety more common in African and Caribbean cooking) have a different texture and less natural sweetness and are not ideal for this particular recipe. Stick with the bright orange-fleshed sweet potatoes — the Beauregard or Jewel varieties are the most widely available and both work perfectly.

Is this recipe good for Thanksgiving?

It is one of the absolute best Thanksgiving recipes in this collection — full stop. These smoked sweet potatoes replace the traditional marshmallow-topped sweet potato casserole with something far more sophisticated, dramatically more flavorful, and completely conversation-worthy at the holiday table. They also free up oven space on the most oven-crowded cooking day of the year, which is an enormous practical benefit. Make them up to 3 days ahead, reheat in the oven while the turkey rests, and add the butter fresh at the table.

Can kids eat this recipe with the bourbon in the butter?

The heat of the smoked potato will cook off most of the alcohol in the bourbon butter as it melts into the hot flesh — but if you are serving children or prefer to avoid alcohol entirely, it is easy to make a separate batch of the butter with the bourbon swapped out for 1 tablespoon of pure vanilla extract plus 1 tablespoon of apple juice. The butter is still wonderfully rich, sweet, and aromatic without any bourbon at all. Both versions are genuinely delicious and nobody at the table will feel like they are missing out.

How do I know when smoked sweet potatoes are done?

The most reliable test is the fork or skewer test — insert a thin skewer or fork into the thickest part of the potato. If it slides in with absolutely zero resistance, like pushing through softened butter, the potato is done. Visually, the skin will look bronzed, slightly wrinkled, and fragrant with smoke, and the potato will feel completely soft when gently squeezed through a towel. If there is any firmness at the center, return it to the smoker for another 15 to 20 minutes and test again. Internal temperature should reach around 205°F to 210°F for perfect tenderness.
