Why Grill Sweet Potatoes?
- Caramelization: High-heat grilling brings out sweet potatoes’ natural sugars, creating a caramelized exterior and smoky flavor.

- Versatility: Perfect as a side for grilled meats, vegetarian mains, or standalone appetizers.
- Visual Appeal: Wedges and rounds deliver vibrant color and grill marks for a striking presentation.
Ingredients: What You’ll Need
| Ingredient | Amount | Role in Recipe |
|---|---|---|
| Sweet potatoes | 3 large | Main vegetable, base for wedges or rounds |
| Unsalted butter | 1 1/2 sticks (12 tbsp, softened) | Forms the compound butter for finishing |
| Molasses | 1/4 cup | Adds depth and sweetness to butter |
| Orange zest | 1 tsp, finely grated | Bright citrus note for compound butter |
| Ground cinnamon | Pinch | Warm spice for aromatic butter |
| Kosher salt & pepper | To taste | Seasoning for butter and sweet potatoes |
| Canola oil | As needed for brushing | Keeps wedges from sticking and promotes even browning |
| Green onions | 4, thinly sliced on the diagonal | Garnish for flavor and color |
Step-by-Step Instructions
1. Par-Cook the Sweet Potatoes
- Place whole sweet potatoes in a large pot of salted water.
- Boil until just tender when pierced (10–15 minutes).
- Drain well and let cool slightly for easier handling.
- This step helps the potatoes cook faster and ensures creamy interiors without burning on the grill.
2. Prepare the Orange-Molasses Compound Butter
- In a bowl, combine softened butter, molasses, orange zest, and ground cinnamon.
- Season with kosher salt and freshly ground black pepper to taste.
- Mash together with a fork until fully blended and smooth.
- You may cover and refrigerate the butter up to two days ahead; bring to room temperature before serving for easy spreading.
3. Slice and Season the Sweet Potatoes
- Cut cooled sweet potatoes into 6–8 wedges each for maximum grill surface and visual interest. Alternatively, slice into thick rounds for more uniform grilling.
- Brush each piece with canola oil and season with salt and pepper. Oil prevents sticking and helps browning.
4. Grill the Sweet Potato Wedges
- Preheat your grill to medium-high.
- Place wedges or rounds directly on the grill grates.
- Grill 3 minutes per side, turning until golden brown and lightly charred. Total grilling time is 6–8 minutes.
5. Finish and Serve
- Transfer grilled sweet potatoes to a platter while hot.
- Immediately brush generously with the prepared orange-molasses butter. The warmth will melt the butter for luscious coating.
- Sprinkle with sliced green onions for herbal freshness and color.
- Serve right away for best flavor and texture.
Tips for Perfect Grilled Sweet Potatoes
- Par-cooking is crucial—without it, sweet potatoes are likely to scorch before softening inside.
- Cut wedges evenly for consistent grilling results and professional appearance.
- Bring all ingredients to room temperature before grilling for easier preparation.
- For smoky depth, consider using a charcoal or wood-fired grill, though gas works well too.
- Adjust the flavor of the compound butter by using lime or lemon zest or adding fresh herbs like thyme.
Serving Suggestions
- Pair with grilled chicken, fish, steak, or pork at your next barbecue.
- Serve as a vegetarian main dish set alongside black beans, quinoa, or lentil salad.
- Include as a unique appetizer for a summer gathering or as part of a holiday feast.
- Combine with smoked cheese or yogurt dip for extra richness.
- Add toasted nuts (such as pecans) for crunch and a Southern-inspired twist.
Frequently Asked Questions (FAQs)
Can I make the orange-molasses butter ahead of time?
Yes. Prepare the compound butter up to two days in advance and keep it covered in the refrigerator. Allow it to come to room temperature for 20 minutes before spreading on hot potatoes.
Can sweet potatoes be grilled without par-cooking?
It is not recommended. Par-cooking by boiling helps guarantee tender centers and prevents burning before the potatoes cook through.
Is there a substitute for molasses in the butter?
Dark honey or maple syrup can be substituted. Molasses, however, gives a deep, rich flavor that pairs exceptionally well with sweet potatoes.
What other seasonings work well with grilled sweet potatoes?
Try cumin, smoked paprika, chili powder, or fresh herbs such as rosemary and cilantro to customize the flavor profile.
Can I prepare sweet potatoes in advance?
Boil and slice the potatoes ahead of time. Grill and finish with butter and green onions just before serving for best results.
Nutrition and Common Variations
Sweet potatoes are naturally rich in Vitamin A, fiber, and complex carbohydrates. Cooking with butter adds fat and calories, but you can use olive oil instead for a lighter version. For vegan options, substitute dairy-free butter and ensure canola or vegetable oil for grilling.
Common Recipe Variations
- Spicy Sweet Potatoes: Add cayenne or chipotle powder to both the pies and compound butter.
- Lime-Honey Butter: Use lime zest and honey instead of orange and molasses for a tangy, fresh take.
- Herbed Grilled Sweet Potatoes: Add chopped fresh thyme or rosemary right before serving.
- Rustic Rounds: Slice potatoes in thick rounds for even more surface area and easy stacking.
Expert Tips for Success
- Use a grill basket for easier handling of smaller wedges or rounds, especially on large outdoor grills.
- Don’t overcrowd the grill: Place sweet potatoes in a single layer to ensure even cooking and beautiful grill marks.
- Oil your grill grates before grilling for simple cleanup and to further minimize sticking.
- Let potatoes cool briefly after boiling for clean, safe slicing—use a sharp chef’s knife.
Pairings & Complementary Dishes
- Grilled sweet potatoes pair beautifully with tangy coleslaw, barbecued ribs, and fresh corn salad.
- Serve alongside grilled salmon brushed with citrus marinade for a coordinated meal.
- For a fall-themed table, serve with roasted turkey and cranberry relish.
