Preheat the oven to 400°F.

Spread the sweet potato wedges out over a large baking sheet.

Drizzle with the olive oil and sprinkle with the cayenne.

Mix around well with your hands (make sure you wash your hands afterward before touching anything, especially your eyes).

Season with salt and pepper.

Bake for about 20 minutes, checking on them to prevent burning and flipping halfway through the cooking time.

Remove from the oven, sprinkle the lime juice over them, and serve with Chimichurri (if using).
