Creating Crispy Oven Baked Sweet Potato Fries is simple if you carefully follow these steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Sweet Potatoes: Peel the sweet potatoes and cut them into ¼-inch thick fries. Aim for uniform sizes for even cooking.
3. Soak the Fries: Place the cut fries in a bowl of cold water and let them soak for at least 10 minutes. This helps to remove excess starch, making them crispier.
4. Drain and Dry: After soaking, drain the fries and thoroughly pat them dry with a kitchen towel. Removing moisture is key for crispiness.
5. Season the Fries: In a large bowl, toss the fries with olive oil, salt, black pepper, paprika, garlic powder, onion powder, and cayenne (if using). Make sure they are evenly coated.
6. Arrange on a Baking Sheet: Spread the fries in a single layer on a baking sheet. Make sure they are not overcrowded; space allows for better browning.
7. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes. Flip the fries halfway through to ensure they cook evenly.
8. Check for Crispiness: Keep an eye on the fries during the last few minutes. They should be crispy and lightly golden when finished.
9. Cool Slightly: Let the fries cool for a couple of minutes before serving. This cooling time helps them firm up.
10. Serve Immediately: Enjoy while hot for the best texture.
