Prep Time 15 minutes mins
Cook Time 20 minutes mins
- 4 medium sweet potatoes
- 2 tablespoons olive oil
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 cups mini marshmallows
- 1 tablespoon butter
- optional fresh herbs (like thyme or chives)
Preheat the grill to medium-high heat. If you’re using a grill pan on the stove, heat it over medium-high. You want a nice sear without burning the potatoes.
Slice the sweet potatoes into thick rounds or wedges about ¾ inch thick. This size holds up to grilling and caramelizes nicely.
Toss the potato pieces with olive oil, salt, and pepper until evenly coated.
Grill the potatoes, turning once, until they are tender inside and have a light char on the outside, about 8–12 minutes depending on thickness.
Once the potatoes are tender and lightly charred, reduce heat to low or move them to a cooler part of the grill. Scatter the marshmallows over the potatoes in a single layer. Close the grill lid and allow the marshmallows to roast just until they puff and turn golden brown, about 1–2 minutes. Watch closely—they can burn quickly.
Finish by dotting the potatoes with butter; let it melt into the edges as the marshmallows thickly cover the tops. If you like, sprinkle with fresh herbs for a bright contrast.
Serve immediately while the marshmallows are still melty and the potatoes are warm. A light sprinkle of flaky salt at the end can be a lovely finish.
