Creating crispy oven baked sweet potato fries is a straightforward process. Follow these simple steps to achieve perfectly baked fries:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). This high temperature helps achieve that desired crispiness.

2. Prepare the Sweet Potatoes: Wash and peel the sweet potatoes. Cut them into even wedges or matchsticks, ensuring they are about the same size for even cooking.

3. Coat with Oil and Seasoning: In a large mixing bowl, toss the sweet potato fries with olive oil, garlic powder, paprika, salt, pepper, and cayenne, if using. Make sure they are evenly coated.

4. Spread on a Baking Sheet: Line a baking sheet with parchment paper for easier cleanup. Spread the coated sweet potato fries in a single layer on the sheet, ensuring they are not overcrowded.

5. Bake: Place the baking sheet in the preheated oven and bake for 25-30 minutes. Flip the fries halfway through baking to ensure they are golden and crispy on all sides.

6. Check for Doneness: The fries should be crispy and slightly browned when done. Keep an eye on them during the last few minutes to prevent burning.

7. Remove and Cool: Once cooked, remove the fries from the oven and allow them to cool for a few minutes on the baking sheet.

8. Garnish: If desired, sprinkle with fresh parsley for added flavor and color.

Following these steps will help you create the perfect crispy oven baked sweet potato fries that are sure to impress everyone at your table.
