These garlic and herb-grilled sweet potato fries are easy to make and full of flavor. The sweet potatoes are boiled until tender, then grilled with garlic, thyme, and chili flakes for a deliciously crispy and aromatic side dish. They’re perfect for any meal!
Ingredients Needed:
- 6 large sweet potatoes
- Salt
- 5 tablespoons olive oil
- 6 cloves garlic, finely chopped
- 2 teaspoons finely chopped fresh thyme leaves
- 1/4 teaspoon red chili flakes
- 2 tablespoons finely chopped fresh flat-leaf parsley
How To Make Garlic and Herb Grilled Sweet Potato Fries?
- Boil the Sweet Potatoes: Place the sweet potatoes in a large pot of cold water, add 2 tablespoons of salt, and cook until tender but still firm, about 15 minutes. Drain and let cool slightly.
- Prepare the Grill: Heat the grill to high.
- Make the Garlic Mixture: While the potatoes are cooling, heat 2 tablespoons of olive oil in a small sauté pan on the grill. Add garlic, thyme, and chili flakes. Cook for about 45 seconds until the garlic is soft. Remove from heat.
- Slice and Grill the Potatoes: Slice each potato in half lengthwise, then cut each half into 3 or 4 wedges, depending on the size. Brush the wedges with the remaining 3 tablespoons of olive oil and season with salt. Grill the wedges for about 6 minutes, until golden brown and tender.
- Toss and Serve: Remove the fries from the grill and immediately toss with the garlic mixture and chopped parsley. Serve warm.

Recipe Tips:
- Don’t Overcook the Potatoes: Boil the sweet potatoes just until they are tender but still firm. Overcooking them will make them too soft and harder to slice into wedges.
- Use High Heat on the Grill: Make sure your grill is on high heat. This helps the fries cook quickly and get a crispy, golden exterior while keeping the inside tender.
- Brush the Wedges Well with Oil: Don’t skip the step of brushing the wedges with oil before grilling. It helps them crisp up and adds more flavor.
- Check for Crispiness: Grill the wedges until they are golden brown and crispy on the edges. Keep an eye on them to avoid burning, but don’t undercook them.
- Toss Immediately After Grilling: Toss the fries with the garlic mixture and parsley right after they come off the grill. This ensures the flavors are absorbed while they are still warm.
How To Store & Reheat Leftovers?
- Refrigerate: Let the leftover garlic and herb-grilled sweet potato fries cool to room temperature. Then, place them in an airtight container and refrigerate for up to 3 days.
- Freeze: If you want to freeze the fries, let them cool completely before transferring them to a freezer-safe container. They can be frozen for up to 1 month.
- Reheat: Preheat the air fryer to 350°F. Place the fries in the basket and air fry for 3-5 minutes, or until they are heated and crispy.
