This baked sweet potato on grill recipe transforms humble sweet potatoes into smoky, caramelized masterpieces with crispy edges—no oven required. 🔥 After years of perfecting grill techniques, I've cracked the code for achieving that ideal balance of tender flesh and golden-brown skin, all while infusing deep smoky flavor from the flames.
The secret lies in proper preparation and heat management, ensuring your sweet potatoes emerge perfectly cooked every time.
What sets this method apart is the ability to control both the interior and exterior cooking simultaneously. By using indirect heat, you create a self-basting environment that steams the sweet potato while the grill's char adds that coveted smoky crust.
The key steps—piercing for even cooking, seasoning generously, and monitoring heat—ensure you never end up with a dry or undercooked potato again. This technique works equally well for dinner or dessert, making it incredibly versatile.
Once you've mastered the grill, the possibilities for serving are endless. I love finishing them with a pat of butter and a sprinkle of cinnamon for a dessert-like treat, or keeping them savory with a dash of smoked paprika and a smear of cream cheese.
The crispy edges provide the perfect textural contrast to the creamy, caramelized interior, creating a dish that's both satisfying and impressive.
Safety is paramount when grilling sweet potatoes—always use long tongs to avoid burns, and keep a spray bottle handy for flare-ups. This method delivers restaurant-quality results with minimal effort, proving that the grill isn't just for meats. Let's get started on creating your next grillside showstopper.
Ingredients for baked sweet potato on grill
Simple ingredients that transform into restaurant-quality grill masterpieces with crispy edges and smoky flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Sweet Potatoes 🍠 | 4 whole | Medium size for even cooking |
| Unsalted Butter 🧈 | ½ cup | Melted for brushing |
| Smoked Paprika 🌶️ | 1 ½ tbsp | For deep smoky flavor |
| Ground Cinnamon 🍃 | 1 tsp | Sweet touch for dessert finish |
| Kosher Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for best flavor |
| Olive Oil 🫒 | 1 tbsp | For piercing and brushing |

The sweet potatoes are the star—pick medium-sized ones for even cooking. Trader Joe's or local farm stands often have perfect ones, but any grocery store will work. Look for firm, smooth skins with no soft spots. The key to crispy edges lies in proper piercing: use a skewer to make 4-6 holes around the circumference before grilling. For extra smoky flavor, preheat your grill to medium-high heat (400-450°F) and let it get those beautiful char marks going before placing the potatoes on.
No smoked paprika? Substitute with 1 tsp regular paprika plus 1/2 tsp liquid smoke—it's a game-changer for that authentic grillhouse taste. Want to keep it savory? Skip the cinnamon and add 1/2 tsp garlic powder instead. The butter should be melted but not hot when brushing—just warm it in the microwave for 40 seconds. For dessert-style, add a drizzle of honey after grilling. And if you're feeling fancy, top with cream cheese mixed with a pinch of smoked salt for a creamy, smoky finish.
Grill-cooked sweet potatoes stay best for 2-3 days in the fridge, but they're even better the next day—the flavors meld beautifully. Store them in an airtight container with a paper towel to absorb any moisture. To reheat, wrap in foil and warm on the grill for 5-10 minutes—this restores that crispy exterior. For meal prep, grill a batch ahead and portion them into containers with your favorite toppings. They freeze surprisingly well too—just wrap individually in foil and store for up to 3 months.

Step-by-step instructions for grilled sweet potatoes with crispy edges
Here's how to transform humble sweet potatoes into smoky, caramelized masterpieces with perfectly crispy exteriors.
👨🍳 Step 1: Prep and Season the Sweet Potatoes
Start by preheating your grill to medium-high heat (400°F). While it heats, scrub the 4 whole medium sweet potatoes clean with a vegetable brush under cool water. Pat them completely dry with paper towels—this step is crucial for crispy skin. You want them bone dry so the seasoning sticks and the skin gets that gorgeous char.
Use a fork to pierce each sweet potato about 6-8 times on all sides. This helps prevent them from exploding on the grill and allows steam to escape, promoting even cooking. In a small bowl, mix together the 1.5 tbsp smoked paprika, 1 tsp ground cinnamon, 1 tsp kosher salt, and 0.5 tsp freshly ground black pepper. Rub this mixture all over the sweet potatoes, pressing it into the fork holes and making sure to get it into every crevice.
🔥 Step 2: Grill Until Tender with Crispy Skin
Place the seasoned sweet potatoes directly on the grill grates, spacing them about 2 inches apart so they don't steam. You'll hear a satisfying sizzle as the juices start to release. Grill for 25-30 minutes, turning them every 10 minutes to ensure even cooking and crispy skin on all sides. You'll know they're ready when a knife slides in easily and the skin develops deep grill marks and crispy spots.
Here's the thing—don't be tempted to move them around too much. Let them develop those beautiful char marks. If you notice the skin browning too quickly before the inside is tender, you can move them to a cooler part of the grill or cover them with the grill lid for 5-10 minutes to slow the cooking process. The goal is that perfect balance of crispy exterior and tender interior.
🍳 Step 3: Brush with Butter and Honey for Caramelization
Once the sweet potatoes are tender, remove them from the grill and let them rest for 5 minutes. While they rest, melt the 0.5 cup unsalted butter in a small saucepan over low heat until just melted. Stir in the 1 tbsp honey and let it warm through for about 1 minute. The mixture should be smooth and slightly fragrant.
Using a pastry brush, generously brush the melted butter-honey mixture all over the warm sweet potatoes. This step creates that irresistible caramelized glaze that ties all the flavors together. For extra decadence, you can also sprinkle a little more of the smoked paprika-cinnamon blend on top before serving. The residual heat from the potatoes will help the butter melt and create that beautiful sheen.
🥘 Step 4: Optional Cream Cheese Topping (Savory Twist)
For a savory-sweet variation that takes these grilled sweet potatoes to the next level, soften the 2 oz cream cheese by microwaving it for 10-15 seconds or placing it in a bowl of warm water for 2 minutes. Once softened, spread it evenly over the top of each sweet potato. The cream cheese will melt slightly from the residual heat, creating a creamy, tangy contrast to the smoky sweetness underneath.
If you're serving these as a main dish, you can also add a sprinkle of freshly cracked black pepper or a drizzle of the remaining butter-honey mixture. For a complete meal, serve with grilled chicken, black beans, or a simple green salad. The cream cheese topping works particularly well with savory sides, balancing the sweetness of the potatoes.
⏰ Step 5: Serve Immediately with Wooden Skewers
Before serving, insert one of the 4 soaked wooden skewers through each sweet potato lengthwise. This makes them easier to handle and adds a rustic presentation. Serve immediately while still warm—this is when the textures and flavors are at their peak. The crispy skin should give way to tender, fluffy flesh with that perfect caramelized glaze.
Real talk: These grilled sweet potatoes are even better the next day when the flavors have had time to meld. If you're planning ahead, let them cool completely and store them in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave for 2-3 minutes or in a 350°F oven for 15 minutes to restore that crispy texture. The flavors only deepen over time, making them even more irresistible.
Pro Tips For Making Baked Sweet Potato On Grill
- PUNCTURE THEM FIRST: Sweet potatoes are dense—skip piercing and you’ll end up with a mushy mess. Use a fork or skewer to make 4-5 holes in each one before grilling; this lets steam escape and ensures even cooking. (Yes, even if you’re impatient like me, resist the urge to skip this.)
- SALTY BUTTER MATTERS: Unsalted butter here isn’t a typo—it gives you full control over flavor. Use about 1 tablespoon per potato, then add salt after melting it into the flesh. Too much salt upfront makes the sweet potatoes bitter. (And no, you can’t just eyeball it.)
- GRATE THE CINNAMON: Ground cinnamon burns fast and clumps. Grate your own from a stick—it’s fresher, more aromatic, and won’t turn to dust when you brush it on. Sprinkle lightly over the butter mixture; a heavy hand makes the potatoes taste like dessert, not dinner.
- FOIL THEM HALFWAY: Start them uncovered on high heat to get grill marks, then tent with foil for the last 15 minutes. This traps moisture without steaming them into soggy blobs. (I learned this the hard way—overcooked sweet potatoes are a crime.)

Frequently asked questions
Can I grill sweet potatoes on a gas grill?
Gas grills work perfectly for this recipe. Preheat to medium-high heat (400-450°F) and maintain consistent heat by keeping the lid closed. The key is to avoid flare-ups—keep the burners clean and use a spray bottle with water if needed. Gas grills actually have the advantage of more precise temperature control compared to charcoal.
How do I know when sweet potatoes are done grilling?
They're ready when a sharp knife slides in easily with just light pressure and the skin has deep grill marks. For medium sweet potatoes, this usually takes 25-30 minutes total grilling time. The interior should be tender all the way through with no resistance—if it's still firm, return them to the grill for another 5-10 minutes.
What if my sweet potatoes split while grilling?
This happens when steam builds up too quickly! Always pierce them 6-8 times before grilling to allow steam to escape. If they split while cooking, just flip them over and continue grilling—they'll still taste delicious. For extra insurance, choose slightly smaller potatoes (8-10 oz each) as they're less prone to splitting.
Can I make these ahead of time?
Yes! Grill them up to 2 days in advance and store in an airtight container. Reheat by wrapping in foil and warming on the grill for 5-10 minutes or in a 350°F oven for 15 minutes. The flavors actually improve overnight—the smoky caramelization deepens, making them even more delicious the next day.
What's the best way to serve grilled sweet potatoes?
For a complete meal, serve with grilled chicken, black beans, and avocado slices. The smoky sweetness pairs perfectly with savory proteins. For dessert-style, top with melted butter, cinnamon, and a drizzle of honey. The crispy edges make them great for sharing—just skewer them with wooden picks for easy serving!
