- 1 teaspoon paprika – or smoked paprika for a richer, bolder flavor

How to Make Crispy Oven Baked Sweet Potato Fries
1. Preheat the Oven
Preheat to 425°F (220°C). Place a baking sheet inside while it heats—this ensures instant sizzle and a crispy base when the fries go in.
Food science insight: Preheating the baking sheet increases contact heat, which reduces sogginess and accelerates caramelization.
2. Prepare the Sweet Potatoes
Peel (optional) and cut sweet potatoes into ¼-inch thick fries. Uniform cuts ensure even baking.
3. Soak the Fries
Place fries in a bowl of cold water for 30 minutes to remove excess starch, which helps them get ultra crispy.
4. Dry Thoroughly
Drain and pat the fries completely dry with paper towels. Any lingering moisture will cause steaming instead of roasting.
5. Season the Fries
In a large bowl, toss fries with olive oil, garlic powder, paprika, salt, and pepper. If using cornstarch, sprinkle it in now and toss until evenly coated.
6. Bake to Perfection
Carefully remove the hot baking sheet from the oven. Spread fries in a single, even layer, ensuring they don’t touch. Bake for 25–30 minutes, flipping halfway through.
7. Cool Slightly Before Serving
Let fries cool for 2–3 minutes after baking. This allows them to firm up and finish crisping.

Ingredients
2 medium sweet potatoes peeled (optional) and cut into fries 2 tablespoons olive oil 1 teaspoon garlic powder 1 teaspoon paprika smoked paprika is optional for extra flavor 1 teaspoon salt ½ teaspoon black pepper Optional: 1 tablespoon cornstarch for extra crispiness
Instructions
Preheat the Oven: Preheat your oven to 425°F (220°C). Place a baking sheet inside the oven while it heats to get it nice and hot. Prepare the Sweet Potatoes: Peel the sweet potatoes (optional) and cut them into 1/4 inch thick fries. Try to make them as uniform as possible to ensure they cook evenly. Soak the Fries: Place the cut sweet potato fries in a bowl of cold water for 30 minutes. This step removes excess starch, which is key to getting crispy fries. Season the Fries: After soaking, drain and pat the fries dry with a paper towel to remove moisture. In a large bowl, toss the fries with 2 tablespoons olive oil, 1 teaspoon garlic powder, 1 teaspoon paprika, 1 teaspoon salt, and ½ teaspoon black pepper. If you’re using cornstarch for extra crispiness, sprinkle it in now and toss everything together. Bake the Fries: Carefully remove the hot baking sheet from the oven. Spread the fries in a single layer on the sheet, ensuring they aren’t overcrowded. Bake for 25-30 minutes, flipping the fries halfway through, until they are golden brown and crispy. Check for Crispiness: Once the fries are crisp and golden, remove them from the oven and let them cool for a few minutes before serving.
Notes
Using Cornstarch for Extra Crispiness:
If you want your sweet potato fries to have that extra crunch, try adding a little cornstarch!
When you toss the fries in cornstarch before baking, it creates a light coating that helps absorb moisture, making the outside super crispy while keeping the inside soft and tender.
Just sprinkle about 1 tablespoon of cornstarch over your seasoned fries, toss them around so they’re all coated, and bake as usual.
