Ingredients
- 2 large sweet potatoes, peeled and cut into 1/4-inch fries
- 2 tablespoons cornstarch
- 2 tablespoons olive oil
- 1 teaspoon salt (plus pepper and paprika, to taste)
How to Make Crispy Baked Sweet Potato Fries
- Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.
- Cut evenly. Slice the sweet potatoes into fries of similar thickness so they cook evenly.
- Coat with cornstarch. Toss the fries with cornstarch first — this is the key step for a crispy exterior, since it draws out moisture and helps them crisp up in the oven.
- Add oil and seasoning. Toss again with olive oil, salt, pepper, and paprika until evenly coated.
- Arrange in a single layer. Spread the fries out on the baking sheet without overlapping — crowding causes steaming instead of crisping.
- Bake. Bake for 20-25 minutes, flipping halfway through, until golden and crisp at the edges.
Tips for the Crispiest Sweet Potato Fries
- Don’t skip the cornstarch coating — it’s the biggest factor in getting a crispy texture
- Give the fries space on the baking sheet; use two sheets if needed rather than crowding one
- For extra crispiness, finish under the broiler for 1-2 minutes at the end, watching closely
How to Store and Reheat
Refrigerator: Store in an airtight container for up to 3 days. Reheating: Reheat in the oven or air fryer at 400°F for 5-7 minutes to re-crisp — microwaving will make them soft.
