- Simple pantry ingredients. No complicated steps or hard-to-find ingredients required.
- Great for meal prep. Make a big batch and reheat throughout the week as a quick side.
- Customizable seasoning. Easily adjust the spice blend to make it sweet, spicy, or savory.
Ingredients
- 2 large sweet potatoes, peeled
- 2 tablespoons olive oil
- 1 tablespoon cornstarch (the secret to extra crispiness)
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt, plus more to taste
- 1/4 teaspoon black pepper
- Optional: pinch of cayenne pepper for heat
Instructions
1. Preheat the oven. Set your oven to 425°F (220°C) and line a large baking sheet with parchment paper. Using a sheet lined with parchment (rather than foil) helps the fries crisp without sticking.
2. Cut the sweet potatoes. Slice the sweet potatoes into even matchsticks, about 1/4 to 1/3 inch thick. Try to keep the sizes consistent, so they cook evenly.
3. Dry the potatoes. Pat the cut fries dry with a paper towel. Removing excess moisture is key to getting them crispy rather than soggy.
4. Toss with cornstarch and oil. In a large bowl, toss the fries with cornstarch first, making sure each piece is lightly coated. Then add the olive oil and toss again until evenly coated.
5. Season. Sprinkle the paprika, garlic powder, salt, pepper, and cayenne (if using) over the fries and toss once more until evenly seasoned.
6. Arrange in a single layer. Spread the fries out on the baking sheet in a single layer, making sure they aren’t touching or overlapping. Overcrowding the pan traps steam and prevents crisping.
7. Bake. Bake for 20 minutes, then flip the fries and bake for another 10–15 minutes, until the edges are golden and crispy.
8. Cool slightly and serve. Let the fries rest on the baking sheet for a couple of minutes before serving — they’ll continue to crisp up slightly as they cool.
Tips for Extra Crispy Fries
- Cut them evenly. Thicker fries take longer to crisp, while thinner ones may burn before the inside cooks through.
- Don’t skip the cornstarch. It creates a light coating that crisps up in the oven, mimicking the texture of fried potatoes.
- Give them space. A crowded pan is the number one reason oven fries turn out soft instead of crispy. Use two baking sheets if needed.
- Use a wire rack (optional). Placing the fries on a wire rack set over the baking sheet allows air to circulate underneath, boosting crispiness even further.
- Serve immediately. Sweet potato fries are crispiest right out of the oven, since they can soften as they sit.
What to Serve With Sweet Potato Fries
These fries are endlessly versatile. Try them with a simple garlic aioli, spicy mayo, or classic ketchup. They also pair well as a side to burgers, sandwiches, or grilled proteins. For dipping sauce inspiration, the Food Network’s guide to homemade dipping sauces is a great place to start if you want to go beyond the basics.
Storage and Reheating
- Refrigerator: Store leftovers in an airtight container for up to 3 days.
- Reheating: For best results, reheat in the oven or air fryer at 400°F (200°C) for 5–8 minutes to restore crispiness. Microwaving will make them soft.
- Freezing: These are best enjoyed fresh, as sweet potatoes can become watery after freezing and thawing.
