01 - Preheat your oven to 425°F. Line a large baking sheet with parchment paper to ensure easy release and prevent sticking.
02 - Carefully slice the peeled sweet potatoes into uniform sticks, approximately 1/2 inch thick, to promote even cooking.
03 - In a spacious mixing bowl, combine the sweet potato sticks with olive oil, smoked paprika, garlic powder, ground black pepper, sea salt, and the optional cayenne pepper. Toss thoroughly until all pieces are evenly coated with the seasoning blend.
04 - Distribute the seasoned sweet potato fries in a single layer across the prepared baking sheet. Ensure ample space between each fry; overcrowding can hinder crispiness.
05 - Roast the sweet potatoes for 15 minutes. Following this initial roasting period, use a spatula to meticulously flip each fry to facilitate consistent browning.
06 - Continue roasting for an additional 15 minutes, or until the fries achieve a desirable golden-brown hue and crisp texture at the edges. Remove from the oven, sprinkle with extra sea salt if preferred, and serve immediately for optimal enjoyment.
