Savory Grilled Sweet Potatoes with Rosemary and Parmesan are a simple, approachable side dish that pairs well with grilled chicken, fish, or a hearty veggie main. The sweetness of the potatoes is softened by the rosemary’s piney aroma, and a light shower of Parmesan adds a savory, nutty finish. It’s not flashy, and that’s part of the charm. This is the kind of dish you reach for when you want something flavorful but easy to pull together on a weeknight.

Ingredients for this Savory Grilled Sweet Potatoes with Rosemary and Parmesan

2 large sweet potatoes, peeled and cut into 1/2-inch rounds
2 tablespoons olive oil
1 teaspoon fresh rosemary, finely chopped
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 cup grated Parmesan cheese
1 clove garlic, minced (optional)

Instructions

Prepare your grill for medium heat and make sure the grates are clean. If you’re using a grill pan, heat it over medium heat on the stove.
In a large bowl, toss the potato rounds with olive oil, chopped rosemary, salt, pepper, and garlic if you’re using it. Aim for a light coating so each slice gets a bit of herb and a little olive oil on both sides.
Thread or place the potato slices directly on the grill grates or grill pan. Grill for 4–6 minutes per side, until they’re tender and have nice grill marks. You want a touch of crispness around the edges.
As they near done, sprinkle Parmesan evenly over the tops. Close the lid for about 1–2 minutes to let the cheese melt slightly and cling to the potatoes.
Remove the potatoes from the grill and let them rest for a minute. Taste, adjust with a pinch more salt if needed, and serve warm.

Cook and Prep Times

Prep time: 15 minutes
Cook time: 12–16 minutes (depending on grill and thickness of slices)
Total time: about 27–31 minutes

Nutritional information

Per serving (about 1/4 of the recipe): roughly 210 calories. This estimate accounts for the olive oil and Parmesan, with modest amounts of protein and carbohydrates from the potatoes. If you skip the garlic, you’ll shave a few calories and a little extra aroma, but the dish remains flavorful thanks to the rosemary and cheese.

Frequently asked questions

Can I make this ahead?

Yes. You can wash and slice the sweet potatoes ahead of time and store them in water in the fridge to prevent browning. Drain and pat dry before tossing with oil and seasonings. The parmesan finish is best done right before serving for that fresh, melty texture.

What if I don’t have a grill?

No problem. Use a grill pan on the stovetop or bake in a 425°F (220°C) oven for about 20–25 minutes, flipping once. Finish under the broiler for a minute or two to mimic the charred edges you get from grilling.

Can I add other herbs?

Absolutely. Thyme pairs nicely with rosemary, and a pinch of smoked paprika adds a gentle warmth. If you like a touch of lemon, a tiny squeeze of fresh juice just before serving brightens the whole dish.
