Foolproof Crispy Oven Baked Sweet Potato Fries—ultra-crunchy outside, fluffy inside. A quick soak + light starch + hot pan = golden fries without deep frying. Includes seasoning ideas and a no-oil option.
Ingredients
FRIES
- 2 lb sweet potatoes, peeled if desired
- 1 tbsp cornstarch or arrowroot
- 2 tbsp avocado or light olive oil (see no-oil variation)
- 1 tsp kosher salt, plus more to finish
- 1/2 tsp black pepper
SEASONING OPTIONS (choose one)
- Smoky-Savory: 1 tsp smoked paprika, 1/2 tsp garlic powder, 1/2 tsp onion powder
- Cajun Heat: 1 tsp cajun seasoning
- Cinnamon Sugar: 1 tsp cinnamon + 1 1/2 tsp turbinado sugar
- Herby Parmesan: 1 tsp Italian seasoning + 2 tbsp grated Parmesan (after baking)
- Chili-Lime: 1/2 tsp chili powder + lime zest (finish with lime juice)
DIPS (optional)
- Garlic-lime yogurt, smoky ketchup, or maple-mustard
NO-OIL OPTION
- 1 1/2 tbsp aquafaba + 1 tbsp cornstarch (replace oil)
Instructions
1. Place 2 sheet pans in the oven and preheat to 425°F (220°C) for 10–15 minutes.
2. Cut sweet potatoes into 1/4-inch batons. Soak in very cold water 20–30 minutes; drain and dry thoroughly.
3. Toss fries with cornstarch until lightly coated. Add oil (or aquafaba for no-oil), salt, pepper, and chosen seasoning; toss to coat.
4. Arrange in a single layer on the hot pans with space between pieces.
5. Bake 15 minutes. Flip with a thin spatula and rotate the pan. Bake 10–15 minutes more until crisp and deeply golden at edges.
6. Transfer to a wire rack for 2 minutes. Sprinkle with a pinch of salt and any finishing zest/Parmesan. Serve hot with dips.
Notes
Make-ahead: Soak, dry, and toss with starch/seasonings; refrigerate on a sheet pan up to 12 hours. Bake on a preheated pan.
Reheat: 450°F on a hot pan 8–12 minutes; air fryer 375°F 5–7 minutes.
Freezer: Par-bake 10–12 minutes; cool; freeze on a pan; store up to 2 months. Bake from frozen 425°F for 15–20 minutes.
No-oil: Use aquafaba + starch; bake as directed. Very crisp with bold seasoning.
