Yield
Serves 4 as a side or snack
Difficulty Level
Easy
Ingredients
- 3 large sweet potatoes, peeled and cut into ½-inch thick fries
- 2 tablespoons cornstarch (or arrowroot powder)
- 3 tablespoons olive oil
- 1 teaspoon smoked paprika
- 1 teaspoon garlic powder
- ½ teaspoon ground cumin
- ½ teaspoon salt, or to taste
- ¼ teaspoon freshly ground black pepper
- Optional fresh parsley, chopped, for garnish
Instructions
- Choose firm sweet potatoes that feel heavy and have smooth, blemish-free skin. Avoid any that are soft or visibly bruised to ensure maximal crispiness and an even bake.
- Cut the sweet potatoes carefully into evenly sized fries-aim for uniform ½-inch thickness to promote consistent cooking and texture.
- Place the fries in a large bowl and soak them in cold water for at least 30 minutes (or up to 1 hour). This crucial step removes excess starch and prevents sogginess, helping achieve that coveted crisp exterior.
- Drain the fries well and pat dry using a clean kitchen towel or paper towels. Moisture is the enemy of crispiness!
- sprinkle the cornstarch over the dried fries and toss gently to coat each piece in a thin, even layer. This extra step creates a delicate crust as they bake.
- Transfer fries to a baking sheet lined with parchment paper or a silicon mat. Drizzle the olive oil and toss to coat thoroughly, ensuring each fry is glistening but not drenched.
- In a small bowl, mix smoked paprika, garlic powder, cumin, salt, and black pepper. Sprinkle this seasoning blend evenly over the fries and toss gently to coat. These layers of flavor enhance the sweet potatoes’ natural earthiness and deepen the aroma.
- Spread fries in a single layer on the sheet, ensuring no overlap to allow maximum heat circulation and crisping.
- Preheat your oven to 425°F (220°C). Place the fries in the middle rack and bake for 15 minutes.
- After 15 minutes, use a spatula to flip the fries carefully and rotate the baking sheet to promote even browning on all sides.
- Bake for an additional 12-15 minutes, or until the fries are golden brown and crispy on the edges but tender inside.
- Remove from the oven and let them cool for 2-3 minutes before serving-this brief rest firms up the fries and intensifies their crunch.
Tips for Success
- Soaking is non-negotiable. Don’t skip the soak-it’s the secret weapon for removing surface starch and avoiding limp fries.
- Uniform cutting is key. Inconsistent sizes mean uneven cooking; aim for fries that are similar in thickness.
- Cornstarch coating elevates crispiness. If avoiding cornstarch, arrowroot powder is a great alternative that yields a similar crunch.
- Don’t overcrowd the pan. Give fries breathing room; crowding traps steam and prevents crisping.
- Experiment with seasoning. Add chili powder or cinnamon for a flavorful twist-just keep the base spices to complement the sweet potato’s flavor.

Q&A
Q&A: Perfectly Crispy Oven-Baked Sweet Potato Fries in 40 Minutes
Q1: What makes sweet potato fries different from regular potato fries?
A1: Sweet potato fries have a naturally sweeter flavor and a softer texture inside, which contrasts beautifully with their crispy exterior.

Q3: How should I cut the sweet potatoes for the crispiest fries?
