Crispy sweet potato fries at home — it is possible, and the secret is cornstarch. A light coating of cornstarch draws out moisture and creates a thin, crunchy shell that gets beautifully golden in the oven.
These fries deliver on the sweet-savory balance that makes sweet potato fries so addictive. Serve them with a spicy chipotle aioli or simply with ketchup for dunking.
Ingredients
Instructions
- 1
Preheat oven to 425°F and line two sheet pans with parchment paper.
- 2
Soak cut sweet potatoes in cold water for 30 minutes. Drain and pat very dry with kitchen towels.
- 3
Toss dried fries with cornstarch until evenly coated. Add oil, paprika, garlic powder, and salt. Toss again.
- 4
Spread fries in a single layer on the prepared pans, making sure they do not touch. Use two pans.
- 5
Bake for 15 minutes, flip, then bake 10 more minutes until golden and crispy. Season with extra salt immediately.

Tips & Storage
Pro Tips
Soaking in water removes excess starch for crispier results.
Do not crowd the pan — use two sheet pans and give each fry space.
Pat the fries completely dry after soaking or the cornstarch will not stick.
Storage
Best served immediately. Refrigerate leftovers for up to 2 days.
Reheating
Reheat in a 350°F oven for 15-20 minutes until warmed through, or microwave individual portions for 2-3 minutes. Add a splash of broth or water to prevent drying. Stovetop reheating over medium-low heat is also effective.
