This baked sweet potato on grill recipe transforms humble sweet potatoes into smoky, caramelized masterpieces with just a few simple steps. š„ As someone who grew up with backyard cookouts, I know how a perfectly grilled sweet potato can elevate any meal from ordinary to extraordinaryāwhether it's served as a side, a hearty main, or a star in a loaded bowl.
The secret lies in the grill itself: indirect heat for even cooking and direct heat for those coveted char marks. You'll start with whole sweet potatoes, scoring the skin to prevent bursting, then let the smoldering coals work their magic while you tend to other dishes.
The result? A tender, slightly crispy exterior with a creamy, caramelized center that's impossible to resist.
What makes this recipe truly versatile is how it adapts to any menu. Serve it as a satisfying side to grilled meats, turn it into a loaded sweet potato bowl with toppings, or enjoy it as a standalone main with a sprinkle of smoked paprika and a drizzle of honey.
The grill's smoky aroma alone makes every bite feel like a celebration.
Ready in just 45 minutes, this method delivers restaurant-quality results without the fuss. The key is patienceāletting the sweet potatoes cook low and slow until they're perfectly tender inside while developing that irresistible char on the outside.
Trust me, once you try this, you'll never bake sweet potatoes any other way.
Ingredients for baked sweet potato on grill
Four simple ingredients plus grill magic turn ordinary sweet potatoes into smoky, caramelized perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes š | 4 whole | Medium-sized, firm and unblemished |
| Olive Oil š« | 2 tbsp | Extra-virgin for best flavor |
| Kosher Salt š§ | 1 tsp | Diamond Crystal preferred |
| Black Pepper š¶ļø | Ā½ tsp | Freshly ground for aroma |
| Smoked Paprika š¶ļø | 1 tsp | For that signature smoky flavor |
| Honey šÆ | 1 tbsp | Optional drizzle for caramelization |
| Wooden Skewers šŖµ | 4 whole | Soaked in water for 30 minutes |
| Charcoal or Wood Chips š„ | 1 package | For smoky flavor (optional) |
| Aluminum Foil š | 1 sheet | Heavy-duty, for wrapping |
The sweet potatoes are the starāpick firm, unblemished ones from the produce section. Trader Joe's and Whole Foods usually have the best selection, but your local grocery store works too. Medium-sized potatoes (about 6-8 oz each) cook evenly and hold up well to grilling. Skip the pre-cut onesāthey bruise easily. If you're using a gas grill, preheat it to medium-high (400Ā°F) for direct heat char marks. Charcoal grills? Build a two-zone fire with coals on one side for indirect heat. The key is patienceāthese need time to develop that smoky exterior while staying tender inside.
No smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. Running short on skewers? Heavy-duty foil or grill baskets are great alternatives. The honey drizzle is optional but worth it for that extra caramelized crunch. For extra smokiness, toss a handful of wood chips (hickory or apple) on the coals. If your grill lacks a thermometer, use the back of your handāabout 6 inches above the grill should feel warm but not scorching. And if you're worried about the potatoes bursting, score the skin lightly with a knife before grilling.
Grill-prepped sweet potatoes keep best when stored in the fridge, wrapped tightly in foil for up to 3 days. For longer storage, pop them in the freezerāwrap individually in foil and freeze for up to 3 months. Reheat in the microwave for 2-3 minutes or warm on the grill for 5 minutes. Pro tip: Portion the toppings (like sour cream, chili, or nuts) separately so they stay fresh longer. These reheat beautifullyāeven better the next day when all those smoky flavors meld together.

Step-by-step instructions for grilled sweet potatoes with smoky char
Here's how to transform simple sweet potatoes into restaurant-worthy grill gems.
š„ Step 1: Prep and Season the Sweet Potatoes
First, scrub the 4 whole large sweet potatoes clean with a vegetable brush under cool water. I like to use a dry brush to remove any dirt from the skināthis helps the seasoning stick better later. Pat them completely dry with paper towels, especially in the crevices where moisture can hide.
Preheat your grill to medium-high heat (around 375-400Ā°F) with the charcoal or wood chips. While it heats, mix together the 2 tablespoons olive oil, 1 teaspoon kosher salt, Ā½ teaspoon black pepper, and 1 teaspoon smoked paprika in a small bowl. This blend gives you that perfect balance of smoky, savory, and slightly sweet flavors. Brush this mixture generously over each sweet potato, making sure to get it in all the crevices.
š³ Step 2: Grill Until Tender with Char Marks
Place the seasoned sweet potatoes directly on the grill grates. Here's the thingāyou want to give them space. Arrange them so they're not touching each other, about 2 inches apart. This allows for even cooking and those beautiful char marks. Let them cook undisturbed for 15-20 minutes, turning occasionally with tongs, until they develop deep brown char marks and feel slightly soft when pressed with a fork.
Don't rush this step. The char marks are what give these sweet potatoes that smoky, grilled flavor. If you notice the skin starting to blister too quickly, you can move them to a slightly cooler part of the grill. You'll know they're ready when the skin is crispy and the flesh yields slightly to gentle pressure.
š„ Step 3: Wrap and Finish with Honey Glaze
Once the sweet potatoes are tender and well-charred, it's time to wrap them in the aluminum foil. This step is crucial for creating that perfect balance of crispy skin and creamy interior. Place each sweet potato in the center of a sheet of aluminum foil and drizzle 1 tablespoon honey over the top of each one. Fold the foil tightly to seal, trapping the steam inside.
Return the wrapped sweet potatoes to the grill and cook for another 10-15 minutes. The honey will caramelize beautifully, adding a touch of sweetness that complements the smoky flavors. You'll know they're done when the foil is slightly puffed and the sweet potatoes feel completely tender when squeezed gently. The internal temperature should reach about 200Ā°F.
šŖ Step 4: Serve with Crispy Skin and Creamy Center
Carefully remove the sweet potatoes from the foil and let them rest for 2-3 minutes before serving. This resting time allows the flavors to meld and the insides to set slightly, making them easier to cut into. Use a sharp knife to slice each sweet potato in half lengthwise, revealing that gorgeous caramelized exterior and creamy interior.
Here's the moment that matters: the contrast between the crispy, charred skin and the soft, sweet flesh should be perfect. If you're serving these as a side dish, you can top them with a sprinkle of fresh herbs or a dollop of Greek yogurt for extra creaminess. These grilled sweet potatoes are versatile enough to be a main dish or a side, but either way, they'll be the star of your meal.
Pro Tips For Making Baked Sweet Potato On Grill
- Poke the Potatoes First: I learned this the hard wayāskipping this step means uneven cooking and a fight to get the center tender. Use a fork or skewer to pierce each potato 4-6 times along the length before grilling; it lets steam escape and speeds up the process.
- Preheat Like Itās Hot: Your grill doesnāt need to be "medium" for sweet potatoesāstart with all burners or zones cranked to high heat. Let it scream for 10-15 minutes before adding the potatoes; this guarantees a crispy skin instead of a sad, damp one.
- Salt Before You Grill: Donāt wait until the end to seasonārub the potatoes with olive oil and a generous pinch of kosher salt (about Ā½ teaspoon per potato) right after poking. This locks in flavor and prevents them from drying out later.
- Foil the Last 10 Minutes: After the skinās crispy but the flesh still feels firm, wrap the potatoes loosely in foil. Let them steam for the final stretchāthis keeps them from burning while finishing soft inside. (Yes, even if youāre impatient like me.)
Best sauces and condiments for this baked sweet potato on grill
Classic Smoky Maple Glaze
This is my go-to sauce for grilled sweet potatoesāsimple yet packed with flavor. Mix 2 tablespoons pure maple syrup, 1 teaspoon apple cider vinegar, and Ā½ teaspoon smoked paprika in a small saucepan.
Simmer over low heat for 3-4 minutes until slightly thickened, then brush generously over the grilled sweet potatoes. The vinegar brightens the sweetness while the smoked paprika ties into the grill's natural char. šÆ
Spicy Chili-Lime Crema
For a zesty kick, blend Ā½ cup sour cream, 2 tablespoons lime juice, 1 teaspoon chili powder, and Ā½ teaspoon cumin until smooth. Dollop this vibrant crema over the grilled sweet potatoes and sprinkle with chopped cilantro.
The lime cuts through the richness, while the chili powder adds a subtle heat that pairs perfectly with the smoky char. I love this topping for a Southwest-inspired meal.
Brown Butter and Sage
Melt 2 tablespoons unsalted butter in a skillet over medium heat until it turns golden brown and nutty. Remove from heat and stir in 2 fresh sage leaves, finely chopped. Drizzle this fragrant butter over the warm sweet potatoes just before serving.
The brown butter adds depth, while the sage brings an earthy aroma that complements the grill's smokiness. Pro tip: Use a silicone brush for even distribution.
Creamy Garlic Aioli
Whip together Ā½ cup mayonnaise, 1 roasted garlic clove, 1 teaspoon Dijon mustard, and Ā½ teaspoon lemon zest for a rich, garlicky sauce. Serve this alongside the grilled sweet potatoes for dipping or as a topping.
The aioli's creaminess balances the sweet potato's natural sweetness, while the garlic adds a savory punch. Store any leftovers in an airtight container in the fridge for up to 3 days.
Sweet and Tangy BBQ Sauce
Use a store-bought or homemade BBQ sauce (I prefer a tangy Kansas City-style) as a bold topping. Warm the sauce slightly in a small saucepan before drizzling over the grilled sweet potatoes.
The smoky, slightly sweet flavors of the BBQ sauce enhance the grill's char, creating a mouthwatering contrast. For extra flair, sprinkle with crushed red pepper flakes before serving.
Fresh Herb Yogurt Dip
Combine Ā½ cup Greek yogurt, 1 tablespoon chopped dill, 1 tablespoon chopped parsley, 1 teaspoon lemon juice, and a pinch of salt. This light, herby dip is perfect for scooping up any leftover sweet potato or using as a topping.
The yogurt adds a cool, creamy element that balances the warm, smoky flavors of the grilled sweet potatoes. It's a refreshing finish to any meal.

Frequently asked questions
Can I grill sweet potatoes without skewers?
If you don't have skewers, place the whole sweet potatoes directly on the grill grates, spacing them about 2 inches apart for even cooking. For extra stability, use a grill basket or wrap them lightly in foil before grilling. The key is to avoid crowding so they develop those beautiful char marks.
How do I know when grilled sweet potatoes are done?
They're ready when the skin is crispy with deep char marks and the flesh yields slightly to gentle pressure (about 45-60 minutes total on the grill). For perfect doneness, check the internal temperatureāit should reach 200Ā°F. The foil-wrapped finish helps steam them to creamy perfection inside.
Can I make this recipe on a gas grill?
Yes! Preheat your gas grill to medium-high (400Ā°F) and use the same indirect/direct heat method. For extra smokiness, add wood chips to the firebox or use a smoker box. Gas grills work greatājust monitor the heat zones closely to avoid burning the skin before the inside cooks through.
What's the best way to reheat grilled sweet potatoes?
Wrap them in fresh foil and reheat on the grill for 5-10 minutes to restore that crispy skin. For microwave reheating, cover with a damp paper towel and heat for 2-3 minutes. The foil method preserves the smoky flavors best while keeping the texture intact.
Can I use regular potatoes instead of sweet potatoes?
Not idealāthey lack the natural sweetness and creamy texture that makes grilled sweet potatoes so special. If you're craving a similar dish, try grilling fingerling potatoes with the same method, but they'll be less tender and more starchy. Sweet potatoes are the star here for their perfect balance of sweetness and heartiness.
