This baked sweet potato on grill recipe transforms humble sweet potatoes into smoky, caramelized masterpieces with a buttery crust—no oven required. 🔥 The secret lies in wrapping them in foil and letting the grill work its magic, creating tender interiors and crispy, flavorful exteriors that taste like they've been slow-roasted for hours. I perfected this technique during a late-night cookout when I realized how much better grilled sweet potatoes taste than their oven-baked counterparts.
The beauty of grilling sweet potatoes is the versatility—you can customize them with seasonings like cinnamon and brown sugar for dessert, or keep it savory with salt, pepper, and a pat of butter for a hearty side.
The foil wrapping ensures they stay moist while the grill imparts that unmistakable smoky flavor. This method is foolproof, requiring just 45 minutes of hands-off time, making it perfect for busy weeknights or lazy weekends.
What you'll end up with is a sweet potato that's perfectly tender inside with a caramelized, buttery crust outside—crisp enough to hold its shape but soft enough to melt in your mouth. The smoky aroma alone will have everyone at the table asking for seconds.
This technique works equally well on a charcoal, gas, or even a pellet grill, so you can enjoy these delicious potatoes no matter what kind of grill you have.
Serve them as a side dish with grilled meats, as a base for loaded baked potato toppings, or even as a dessert with a drizzle of honey and a sprinkle of sea salt.
The possibilities are endless, and the results are always impressive. Let's get started on creating your next grill masterpiece!

No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. Want to skip the honey in the dessert version? Maple syrup or agave gives similar sweetness. The butter can be swapped for olive oil or coconut oil if you're avoiding dairy, though it won't be quite as rich. For savory versions, add crushed red pepper flakes or onion powder if you've got them. Pro tip: if your grill runs hot, wrap the potatoes in a double layer of foil to prevent burning. And if you're using a gas grill, preheat it to medium-high—charcoal grills take a little longer to reach the right temperature. These reheat beautifully—just pop them back on the grill for 10-15 minutes if they've been sitting in the fridge. Store leftovers in an airtight container for 4-5 days, though I rarely have any last that long. The foil-wrapped method means they stay moist, so you can even freeze them for up to 3 months—just thaw in the fridge overnight before reheating. I always make a double batch because these disappear fast at cookouts. The dessert versions? Best served fresh from the grill, but a quick zap in the microwave works if you're in a hurry.

Step-by-step instructions for smoky-grilled sweet potatoes
Get perfectly caramelized sweet potatoes with crispy edges and buttery goodness—every bite delivers smoky flavor and velvety texture.
🔥 Step 1: Prep and Season the Sweet Potatoes
Preheat your grill to medium-high heat (around 375°F). While it heats, scrub the 4 whole large sweet potatoes clean with a vegetable brush under cool water—this removes dirt and helps the seasoning stick better. Pat them completely dry with paper towels.
In a small bowl, mix together the 1.5 tsp kosher salt, 0.5 tsp ground black pepper, 1 tsp smoked paprika, and 0.5 tsp garlic powder. Rub this mixture all over the sweet potatoes, pressing it into the skin so it adheres well. The smoked paprika gives that delicious campfire aroma, while the garlic powder adds subtle depth.
🍳 Step 2: Wrap and Grill for Even Cooking
Cut a 1 sheet of heavy-duty aluminum foil into four equal squares. Place one sweet potato on each foil square and drizzle 1/8 cup of melted unsalted butter (about 1.25 tbsp) over each potato. Fold the foil tightly around each potato, sealing the edges completely to create a sealed packet. This keeps them moist and helps develop that buttery crust.
Place the foil-wrapped sweet potatoes directly on the grill grates. Cook for 45-50 minutes, turning occasionally to ensure even cooking. You'll know they're ready when the foil starts to puff slightly and you can smell that sweet, caramelized aroma. The potatoes should feel soft when gently squeezed through the foil.
🔪 Step 3: Unwrap and Finish with Caramelization
Remove the sweet potatoes from the grill and carefully open the foil packets. Use a fork to poke holes in the tops of the potatoes to allow steam to escape. Return them to the grill, this time foil-free, and cook for an additional 10-15 minutes to develop that beautiful caramelized crust.
Watch closely during this final step—they're done when the skin is deep golden brown and slightly crispy in spots. The inside should be tender enough that a fork slides in easily. For a dessert version, brush the tops with 1 tbsp honey mixed with 1 tbsp brown sugar and sprinkle with 0.5 tsp cinnamon and 1 tsp sea salt, then return to the grill for 2-3 minutes to caramelize the topping.
Pro Tips For Making Baked Sweet Potato On Grill
- PIERCE THE SKIN FIRST: I learned this the hard way—skipping the fork stab makes them explode like overripe fruit. Pierce each potato twice with a fork before grilling, then let them sit for 10 minutes. This keeps the flesh from turning to mush while the outside gets that perfect char.
- USE A GRILL BASKET OR FOIL: Sweet potatoes roll around like drunk toddlers on a hot grill. Either wrap them loosely in heavy-duty foil (poke holes for steam) or use a grill basket—both keep them stable and prevent them from turning into a greasy mess on your coals. (Yes, even if you’re impatient like me.)
- SALT THE POTATOES BEFORE BUTTER: After burning three batches with bland insides, I finally realized: salt the pierced potatoes before grilling, then again after they’re tender. The butter melts into salty, caramelized pockets instead of just sitting on top like a sad garnish.
- GRILL HOT THEN LOW: Start with the grill at 400°F to get a good sear, then drop to 300°F once they’re pierced and charred. This two-stage method guarantees a crispy exterior without turning the inside into glue. (Your future self will thank you—trust me.)
Regional styles of these flavors
Southern BBQ Style
In the South, we don’t just grill sweet potatoes—we turn them into a showstopper side dish with a smoky, slightly sweet profile.
After wrapping them in foil with butter and a pinch of brown sugar, I like to add 1 tsp of chili powder and ½ tsp of cayenne for a subtle kick.
These get served at backyard cookouts alongside pulled pork, where the sweetness of the potato balances the rich, tangy sauce. The key is to grill them over indirect heat for the first 30 minutes to prevent burning before finishing on direct heat for that caramelized crust. 🔥
Southwest Spiced
For a Southwest twist, I swap the smoked paprika for 1 tsp ground cumin and ½ tsp of chipotle powder—this adds a deep, earthy warmth that pairs perfectly with grilled meats.
After the initial foil wrap, I brush the exposed skin with melted butter mixed with ½ tsp of lime zest before the final open grill step. This version is a crowd-pleaser at summer festivals, especially when served with black beans, corn, and avocado.
The lime zest brightens the dish and cuts through the richness of the butter. 🌶️
Caribbean Jerk-Inspired
If you’re craving bold flavors, try a jerk-inspired approach by mixing 1 tsp of jerk seasoning (store-bought or homemade with allspice, thyme, and Scotch bonnet) into the butter before wrapping.
After the foil stage, I finish them on the grill with a quick brush of 1 tbsp of honey and a sprinkle of sea salt, then let the flames char the edges for a smoky-sweet contrast.
These taste like they belong at a beachside luau, and they’re perfect with grilled shrimp or jerk chicken. The jerk seasoning adds complexity that elevates the humble sweet potato to something extraordinary. 🌴
Pacific Northwest Smoked
Up in the Pacific Northwest, where grilling meets slow-smoking, I love wrapping sweet potatoes in foil with ½ cup of applewood chips (crushed) mixed into the butter. The natural sweetness of the wood pairs beautifully with the potato, creating a dish that’s almost dessert-like.
After the foil cook, I finish them on the grill with a drizzle of maple syrup and a sprinkle of flaky sea salt for a touch of sweetness and crunch. This version is a favorite at outdoor gatherings, especially when paired with smoked salmon or grilled lamb chops.
The wood smoke infuses the butter, making every bite taste like a campfire classic. 🌲
Midwest Butter & Herb
In the Midwest, where hearty sides are king, I keep it simple but flavorful with a butter and herb twist.
After the foil wrap, I finish the potatoes on the grill and then top them with a pat of softened butter mixed with 1 tsp of chopped fresh rosemary and ½ tsp of garlic powder.
The herbs add a fresh, aromatic note that cuts through the richness of the butter, while the garlic ties everything together. This version is a staple at family gatherings, especially when served with grilled steaks or burgers.
The rosemary gives it a sophisticated touch without overpowering the natural sweetness of the potato. 🌿

Frequently asked questions
Can I grill sweet potatoes without foil?
Yes, but expect different results! Grilling sweet potatoes uncovered gives you a crispier skin and more smoky flavor, but they'll dry out faster. For best results, cut them in half lengthwise and grill cut-side down for 20-25 minutes on medium heat, brushing with butter every 5 minutes. The flesh will be slightly firmer but still tender—great for those who prefer texture over ultra-soft interiors.
How do I make these sweeter for dessert?
After the foil cooking, brush the exposed skin with 1 tbsp honey mixed with 1 tbsp brown sugar, then sprinkle with ½ tsp cinnamon and 1 tsp sea salt. Grill uncovered for 2-3 minutes to caramelize. For extra decadence, top with whipped cream or a scoop of vanilla ice cream—just watch them closely to prevent burning!
Why are my grilled sweet potatoes still hard inside?
Undercooked centers usually mean either too-high heat or not enough cooking time. Check your grill temp—it should be 375°F (medium-high). If using a gas grill, move them to a cooler zone if flames are too fierce. For extra insurance, poke with a fork before unwrapping; if it slides in easily, they're done. Smaller potatoes or thicker skins may need 5-10 extra minutes of foil cooking.
Can I use this method for regular potatoes?
Russet or Yukon Gold potatoes work great—just reduce cooking time to 30-35 minutes in foil (they cook faster than sweet potatoes). Skip the dessert toppings and focus on savory seasonings like rosemary, garlic, or smoked paprika. The texture will be fluffier inside, perfect for loaded potato toppings or as a hearty side.
What's the best way to reheat leftovers?
Wrap cooled potatoes in fresh foil and reheat on the grill over medium heat for 10-15 minutes, or microwave for 2-3 minutes with a splash of water to restore moisture. For crispy skin, finish with 1 minute under the broiler. Avoid reheating uncovered in the microwave—they'll dry out completely!
