This barbecue sweet potato recipe transforms humble tubers into smoky, caramelized perfection with a sticky glaze that'll have everyone reaching for seconds. 🔥 I developed this method after years of perfecting the balance between tender flesh and crispy edges—no more mushy sweet potatoes here.
The secret lies in high-heat roasting followed by a quick glaze that locks in moisture while adding that signature smoky depth.
What sets this recipe apart is the two-stage cooking process: first, roasting whole sweet potatoes until their edges caramelize and their centers soften, then finishing them with a homemade glaze that's sweet, smoky, and just sticky enough to make every bite irresistible.
I use a blend of brown sugar and molasses for depth, with a touch of smoked paprika to echo that campfire aroma without needing a smoker.
The result is a dish that's hearty enough to stand alone but pairs beautifully with grilled meats, salads, or even as a dessert when topped with whipped cream and cinnamon. The texture contrast—crispy skin, tender flesh, and that glossy glaze—makes it impossible to eat just one.
This is comfort food elevated to restaurant-quality status, and it only takes about 45 minutes to achieve.
Whether you're cooking for a crowd or treating yourself to a special meal, these barbecue sweet potatoes deliver that perfect balance of sweet, smoky, and savory.
The best part? They reheat beautifully, making them ideal for meal prep. Let's get started on creating this crowd-pleaser that tastes like summer all year round.
Ingredients for barbecue sweet potato
Six ingredients transform simple sweet potatoes into restaurant-quality barbecue perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 3 lbs | Medium-sized, unpeeled |
| Brown Sugar 🍚 | ½ cup | Packed, light or dark |
| Molasses 🍯 | ¼ cup | Unsulphured preferred |
| Smoked Paprika 🌶️ | 1 tbsp | For authentic smoky flavor |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for richness |
| Honey 🍯 | 1 tbsp | Substitute maple syrup if vegan |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tangy depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For subtle savory note |
| Cinnamon 🌿 | ¼ tsp | Optional for dessert twist |
The sweet potatoes are the foundation—medium-sized and firm means even cooking without mushiness. Grab the organic variety from Whole Foods or your local farmers' market for the best flavor and texture. If you can't find organic, conventional works fine, but scrub them well. For the glaze, molasses is key—it adds that deep, caramelized sweetness that sets this apart. Trader Joe's has a great unsulphured option, or check the baking aisle at Costco for bulk. The smoked paprika? Penzeys or any reputable spice brand—just make sure it's labeled 'smoked' for that authentic barbecue flavor.
No molasses? Maple syrup or dark corn syrup works in a pinch, though molasses gives that signature depth. Running low on apple cider vinegar? Balsamic vinegar does the trick, though it'll be slightly sweeter. The honey can be swapped for maple syrup if you're avoiding it, but it's worth having on hand for that perfect glaze consistency. Freshly ground spices make all the difference—if you've got whole spices, toast them briefly in a dry pan before grinding for even more flavor. The garlic powder is optional but adds a subtle savory note that balances the sweetness perfectly. For a dessert version, add a pinch of cinnamon to the glaze and top with whipped cream.
Sweet potatoes keep well in a cool, dark place for up to 2 weeks, but roast them within 3-4 days for best texture. The glaze ingredients are shelf-stable except for honey, which lasts indefinitely. Prep the glaze ahead and store it in the fridge for up to 1 month. Roasted sweet potatoes reheat beautifully—microwave for 1-2 minutes or oven at 350°F for 10 minutes to restore crispiness. For meal prep, portion the glaze into small containers and drizzle it over the potatoes just before serving to keep them from getting soggy.

- Sweet & Smoky Bang: That molasses-brown sugar combo? It’s like dessert met dinner. The smoked paprika gives it this deep, almost meaty richness, while the sweet potatoes stay tender inside with a crispy edge. Honestly, I’ve had people ask if I grilled these—nope, just oven magic.
- Meal Prep MVP: Make a double batch on Sunday, and you’ve got lunch for the week. The flavors only get better as they sit—slightly sweeter, slightly stickier. Pack them cold in salads, reheat for breakfast hash, or just grab one straight from the fridge. (Yes, even on a Tuesday night.)

Step-by-step instructions for smoky caramelized sweet potatoes
Transform humble sweet potatoes into irresistible barbecue bites with this foolproof method.
🍳 Step 1: Prep and Roast the Sweet Potatoes
Preheat your oven to 425°F and line two rimmed baking sheets with parchment paper. Cut the 3 lbs sweet potatoes into 1-inch chunks, leaving the skin on for texture. Toss the sweet potatoes with 2 tbsp olive oil, 1 tbsp smoked paprika, 1.5 tsp salt, and 0.5 tsp garlic powder until evenly coated.
Spread the sweet potatoes in a single layer on the prepared baking sheets—don't overcrowd, or they won't brown properly. Roast for 25-30 minutes, stirring once halfway through, until the edges are deep golden brown and the potatoes are tender when pierced with a fork. The skin should be crispy while the flesh remains creamy inside.
👨🍳 Step 2: Make the Sticky Glaze
While the sweet potatoes roast, combine 0.5 cup brown sugar, 0.25 cup molasses, 1 tbsp honey, 1 tbsp apple cider vinegar, 0.5 tsp ground black pepper, and 0.25 tsp cinnamon in a small saucepan. Place over medium heat and stir constantly for 5-7 minutes until the mixture thickens slightly and becomes syrupy.
Here's the thing—don't walk away. Molasses burns easily, so keep your eyes on the pan. You're looking for a glossy, amber-colored glaze that coats the back of a spoon. Once it reaches this consistency, remove from heat and let it cool for 2 minutes—it'll thicken further as it sits.
🥘 Step 3: Combine and Caramelize
Transfer the roasted sweet potatoes to a large bowl. Pour the warm glaze over the hot potatoes and toss gently to coat evenly. The residual heat from the potatoes will help the glaze cling and create that signature sticky texture. If the glaze seems too thick, add 1-2 teaspoons of water to loosen it.
Return the sweet potatoes to the baking sheets and broil for 2-3 minutes, watching closely to prevent burning. You want the glaze to bubble and caramelize into a glossy finish. The potatoes are done when they're deeply caramelized on top with a sticky, lacquered appearance.
⏰ Step 4: Rest and Serve
Remove from the oven and let the sweet potatoes rest for 5 minutes before serving. This resting period allows the glaze to set slightly and the flavors to meld. The contrast of crispy edges, creamy centers, and that irresistible sticky glaze is what makes these barbecue sweet potatoes so addictive.
Serve immediately while still warm, either as a side dish or a sweet-savory main. The smoky-sweet flavor profile pairs beautifully with grilled meats, crisp salads, or even on its own as a dessert-like treat. Store leftovers in an airtight container for up to 3 days, though they're best enjoyed fresh from the oven.
Pro Tips For Making Barbecue Sweet Potato
- USE A SKINNY KNIFE: Cut sweet potatoes lengthwise into ½-inch slices—thicker pieces stay raw inside while thinner ones burn before caramelizing. I learned this the hard way after pulling undercooked slabs off the grill.
- SALT THE SLICES FIRST: Toss raw sweet potato slices with ½ teaspoon salt per pound before roasting. This draws out moisture so the caramelized glaze sticks instead of turning into a sticky mess.
- DON’T SKIP THE OIL: Brush slices with olive oil before adding the brown sugar/molasses mix—otherwise, the spices will clump and burn. A light coat also prevents sticking on the grill or sheet pan.
- BAKE THEM COLD: Start sweet potatoes in a 350°F oven for 10 minutes before cranking to 425°F. This evens out cooking and prevents the outer edges from burning while the center stays doughy. (Yes, even if you’re impatient like me.)
Wine and beer pairings for this recipe
Red Wine Pairings
A bold, fruity Zinfandel from California is my go-to pairing for these sweet potatoes. The wine's jammy blackberry and plum notes complement the caramelized sweetness, while its moderate tannins cut through the glaze without overpowering.
Look for a 2020 Dry Creek Vineyard Zinfandel—it’s got that perfect balance of sweet and savory to match the dish. 🍷
For a lighter option, try a Riesling with a hint of smokiness, like a Dr. Loosen Blue Slate from Germany. The wine’s crisp acidity and subtle spice notes enhance the smoky paprika in the glaze, creating a refreshing contrast. Serve it slightly chilled to highlight its vibrant fruit flavors.
White Wine Pairings
A Viognier with its floral and stone fruit notes works surprisingly well with the sweet-savory profile. I love a Domaine Tempier from the Rhône Valley—its peach and apricot undertones mirror the caramelized sweetness of the potatoes. The wine’s slight richness also stands up to the molasses glaze. 🍷
Beer Pairings
For beer lovers, a smoked porter like Goose Island Bourbon County Stout is a game-changer. The beer’s vanilla and caramel notes echo the glaze, while the smoky malt ties into the paprika. Serve it at room temperature for the full experience.
A honey wheat ale, such as Allagash White, is another fantastic match. The beer’s sweetness and subtle spice complement the caramelized edges and sticky glaze, making every bite feel like a perfect harmony. The effervescence also cleanses your palate between bites.
Non-Alcoholic Options
For a refreshing non-alcoholic pairing, try sparkling apple cider with a splash of ginger beer. The effervescence and tartness cut through the richness of the glaze, while the apple notes enhance the sweet potato’s natural sweetness. Chill it well for the best experience. 🍎
A smoky iced tea made with hibiscus and a touch of molasses can also work wonders. Brew a strong hibiscus tea, let it cool, and add a splash of molasses and a pinch of smoked salt. Serve over ice for a drink that mirrors the dish’s smoky-sweet profile.

Frequently asked questions
Can I make this recipe on a grill instead of in the oven?
Grilling adds that extra smoky flavor. Place the sweet potato chunks on a preheated grill over medium-high heat and cook for 15-20 minutes, turning occasionally, until tender with crispy edges. Finish with the glaze by brushing it on during the last 2-3 minutes of grilling. For best results, use a grill basket to prevent small pieces from falling through.
How do I prevent the sweet potatoes from turning mushy?
Keep the skin on and cut them into 1-inch chunks—this helps maintain structure. Roast at 425°F for 25-30 minutes (not too long) and avoid overcrowding the tray. The skin acts as a natural barrier, while the high heat creates crispy edges before the center softens. If they start to look too soft, reduce cooking time by 5 minutes next time.
Can I use regular potatoes instead of sweet potatoes?
While you can use regular potatoes, they won’t have the same sweetness or texture. Sweet potatoes are naturally richer and hold up better to the glaze, creating that perfect caramelized crust. If you're set on regular potatoes, try russets—they’re starchy enough to crisp nicely, but expect a less sweet, more savory result. For best flavor, stick with sweet potatoes!
What’s the best way to reheat these barbecue sweet potatoes?
Reheat in the oven for 10 minutes at 350°F to restore crispiness, or microwave for 1-2 minutes covered with a damp paper towel. For extra crunch, broil for 1-2 minutes after reheating. Avoid reheating in the glaze—it’ll make them soggy. Store leftovers in an airtight container for up to 3 days, but they’re best enjoyed fresh!
Can I make this recipe ahead of time?
Yes! Prep the glaze up to 1 month ahead and store it in the fridge. Roast the sweet potatoes 1 day ahead, then reheat before adding the glaze. For a shortcut, make the glaze and roast the potatoes on the same day, then refrigerate the unglazed potatoes for up to 2 days. Reheat and glaze just before serving to keep everything crispy and flavorful.
