4 medium-sized sweet potatoes (about 2 pounds), scrubbed clean
3 tablespoons extra virgin olive oil (or avocado oil for higher heat)
2 teaspoons smoked paprika
1 teaspoon garlic powder
1 teaspoon onion powder
1 tablespoon brown sugar or maple syrup (optional for enhanced caramelization)

Preparation Time and Servings

Preparation Time: 15 minutes
Cooking Time: 20-25 minutes
Total Time: 35-40 minutes
Servings: 4-6 people

This preparation time is approximately 30% faster than traditional oven-roasted sweet potato methods, making it an excellent choice for weeknight grilling. The active preparation is minimal, allowing you to focus on other dishes while these delicious BBQ sweet potatoes develop their smoky flavor on the grill.

Step-by-Step Instructions

Step 1: Prepare the Sweet Potatoes

Begin by washing your sweet potatoes thoroughly under cold running water. Using a sharp knife, slice them into ½-inch thick rounds or lengthwise into wedges, ensuring consistent thickness for even cooking. For extra-tender results, you can parboil the chunks for 5 minutes before grilling, though this is optional for those short on time.

Step 2: Create the Perfect Seasoning Blend

In a large mixing bowl, combine olive oil, smoked paprika, garlic powder, onion powder, brown sugar (if using), thyme, cayenne, salt, and black pepper. This balanced blend enhances the natural sweetness while adding a smoky depth that makes these BBQ sweet potatoes irresistible.

Step 3: Season and Marinate

Add your sliced sweet potatoes to the seasoning mixture, gently tossing to ensure each piece is evenly coated. For deeper flavor penetration, let them marinate for 15-30 minutes, though you can proceed immediately if pressed for time.

Step 4: Preheat Your Grill Properly

Preheat your grill to medium heat (approximately 350-375°F). Creating distinct temperature zones—one side medium-high and one side lower—gives you flexibility during the cooking process. For gas grills, this means turning half the burners to medium-high and the others to medium-low.

Step 5: Grill to Perfection

Place the seasoned sweet potato pieces on the grill, positioning them perpendicular to the grates to prevent smaller pieces from falling through. Cook for 4-5 minutes on each side until grill marks appear and the edges begin to caramelize. The natural sugars will create a beautiful char that balances with the creamy interior.

Step 6: Manage the Heat for Optimal Results

If the sweet potatoes are charring too quickly on the outside before becoming tender inside, move them to the cooler zone of your grill and close the lid, allowing them to finish cooking with indirect heat for another 5-8 minutes.

Step 7: Serve and Garnish

Transfer your perfectly grilled BBQ sweet potatoes to a serving platter. Sprinkle with additional fresh herbs, a squeeze of lime juice, and perhaps a drizzle of high-quality olive oil or balsamic reduction for an elegant finishing touch that enhances the smoky flavor profile.

Common Mistakes to Avoid

🔸 Cutting pieces too thin, causing them to burn or fall through grill grates
🔸 Skipping the oil, which helps prevent sticking and assists with caramelization
🔸 Using too high heat initially, resulting in a burnt exterior and undercooked interior
🔸 Forgetting to season before grilling, missing the opportunity for flavor penetration
🔸 Not allowing sufficient preheating time for your grill, leading to inconsistent cooking
🔸 Flipping too frequently, which prevents proper grill mark formation
🔸 Overcrowding the grill, which creates steam instead of char in crowded areas

Storing Tips for the Recipe

Maximize the life of your grilled sweet potatoes with these storage tips:

Allow leftover BBQ sweet potatoes to cool completely before refrigerating in an airtight container. They’ll maintain their texture and flavor for up to 4 days, making them perfect for meal prep. For best results when reheating, use a 350°F oven for 10 minutes rather than a microwave to maintain the exterior crispness. These grilled sweet potatoes also freeze surprisingly well—portion them into freezer bags for up to 3 months, then thaw overnight in the refrigerator before reheating.
