That sweet taste you love with a spicy kicker!
Turn the oven up to 450 F. While that's heating up, line a baking sheet with foil.
In a small bowl, stir together the olive oil, maple syrup, and cayenne pepper. Brush the sweet potato slices with this mix, then place them on the baking sheet. Sprinkle the slices with salt and pepper to taste.
Bake the sheet in the preheated oven for 8 minutes. Turn the slices over, brush them again with any leftover maple mix, then continue baking until tender in the middle and crispy on the edges, about 7 minutes more.
