These spicy grilled sweet potato slices are crispy on the outside, tender inside, and packed with smoky, sweet, and spicy flavor. An easy side dish or snack!
Introduction
Honestly, I love recipes that take a simple ingredient and make it taste completely different. These Spicy Grilled Sweet Potato Slices are one of those recipes I keep coming back to. The sweet potatoes become beautifully caramelized around the edges while staying soft and tender in the middle.
I usually serve them with a squeeze of fresh lime right before eating. That little bit of acidity really wakes everything up and balances the natural sweetness of the potatoes. They’re great as a side dish, snack, or even a fun appetizer when you want something a little different.
Ingredients
- 2 large sweet potatoes
- 2 tablespoons olive oil
- 1 teaspoon smoked paprika
- ½ teaspoon chili powder
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ¼ teaspoon cayenne pepper, optional
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 tablespoon honey or maple syrup
- 1 tablespoon fresh lime juice
- 1 tablespoon chopped fresh cilantro or parsley
- Lime wedges, for serving
Step-by-Step Method
1. Prepare the Sweet Potatoes
Wash and scrub the sweet potatoes well. You can peel them if you prefer, but I usually leave the skin on for extra texture.
Slice them into rounds about ½-inch thick. Try to keep the slices fairly even so they cook at the same rate.
2. Make the Seasoning
In a large bowl, combine the olive oil, smoked paprika, chili powder, garlic powder, onion powder, cayenne pepper, salt, black pepper, and honey.
Add the sweet potato slices and toss until every piece is nicely coated.
3. Preheat the Grill
Preheat your grill or grill pan to medium-high heat. Lightly oil the grates to help prevent sticking.
4. Grill the Sweet Potatoes
Place the sweet potato slices on the hot grill.
Cook for about 4–6 minutes per side, turning once they develop dark golden grill marks. Continue cooking until the centers are fork-tender.
If the outside is browning too quickly, lower the heat slightly and let them finish cooking more gently.
5. Add the Finishing Touches
Transfer the grilled sweet potatoes to a serving plate. Sprinkle with fresh cilantro or parsley and drizzle with a little fresh lime juice.
Serve immediately while they’re warm and caramelized.
Cooking Tips
- Cut evenly: Similar-sized slices cook much more evenly.
- Don’t use too much oil: A light coating is enough to encourage browning.
- Watch the honey: Honey helps create those gorgeous caramelized edges, but it can burn over very high heat.
- Adjust the spice: Leave out the cayenne for a milder version or add extra if you like serious heat.
- Don’t overcook: Sweet potatoes should be tender enough to pierce easily but still hold their shape.
- Use lime at the end: I honestly think the fresh lime makes this recipe. It balances the sweet and smoky flavors beautifully.

These grilled sweet potato slices work with so many meals. I usually serve them alongside:
