Creating crispy oven baked sweet potato fries is simple when you follow these steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). A hot oven will help the fries become crispy.
2. Prepare Sweet Potatoes: Peel the sweet potatoes and cut them into thin strips. Aim for uniform thickness to ensure even cooking.
3. Seasoning: In a large bowl, toss the sweet potato strips with olive oil until evenly coated.
4. Add Spices: Sprinkle paprika, garlic powder, onion powder, salt, black pepper, and cayenne pepper over the fries. Toss again to ensure even distribution of the spices.
5. Arrange on Baking Sheet: Line a baking sheet with parchment paper. Spread the seasoned sweet potato fries in a single layer on the baking sheet, ensuring they are not overcrowded.
6. Bake: Place the baking sheet in the preheated oven and bake for 20–25 minutes, flipping the fries halfway through to achieve uniform crispiness.
7. Check for Doneness: The fries are done when they are golden brown and crispy. If needed, you can bake for an additional 5 minutes for extra crispiness.
8. Garnish and Serve: Once done, remove the fries from the oven. Optionally, garnish with fresh parsley before serving.

By following these straightforward steps, you’re on your way to enjoying crispy oven baked sweet potato fries in no time!
