For a cheesy twist on sweet potato fries, try making parmesan sweet potato fries. To make these fries, you will need: sweet potatoes, olive oil, salt, pepper, garlic powder, and grated parmesan cheese. Preheat your oven to 425°F (220°C). Peel and cut the sweet potatoes into thin strips. In a large bowl, toss the sweet potato strips with olive oil, salt, pepper, and garlic powder. Spread the fries out on a baking sheet lined with parchment paper. Bake for about 20-25 minutes, flipping halfway through, until the fries are crispy and golden brown. Sprinkle the fries with grated parmesan cheese and return to the oven for an additional 2-3 minutes, until the cheese is melted and bubbly. Serve immediately and enjoy the cheesy goodness!
