01 - Preheat your oven to 425°F. Line a large baking sheet with parchment paper to prevent sticking.
02 - Carefully cut the peeled sweet potatoes into evenly sized sticks, approximately 1/2 inch thick. Consistency in size promotes even cooking.
03 - In a large mixing bowl, toss the sweet potato sticks with olive oil, smoked paprika, garlic powder, ground black pepper, sea salt, and cayenne pepper (if using) until each piece is thoroughly coated.
04 - Spread the seasoned sweet potato fries in a single layer on the prepared baking sheet. Ensure they do not touch or overlap to achieve maximum crispiness.
05 - Roast in the preheated oven for 15 minutes. Then, using a spatula, carefully flip each fry to the other side. Continue roasting for an additional 15 minutes, or until the fries are golden brown and crispy at the edges.
06 - Remove from the oven, sprinkle with extra sea salt if desired, and serve immediately as a snack or side dish.
