Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the sweet potato fries:
2 large sweet potatoes, peeled and cut into thin fries
2 tablespoons olive oil
1 tablespoon cornstarch
1 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
1/2 teaspoon fine salt
1/4 teaspoon black pepper
For the cilantro yogurt sauce:
3/4 cup plain yogurt
1/4 cup fresh cilantro, finely chopped
1 tablespoon lemon juice
1 small garlic clove, minced
1/4 teaspoon salt
1/8 teaspoon black pepper
1 tablespoon olive oil
Directions
Preheat your oven to 425°F (220°C). Line a large baking sheet with parchment paper.
Peel the sweet potatoes and cut them into evenly sized fries, about 1/4 inch thick. Try to keep them similar in size so they cook evenly.
Place the cut sweet potatoes in a large bowl. Pat them dry with paper towels if they seem moist. This helps them roast better.
Add the cornstarch and toss well until the fries are lightly coated.
Drizzle in the olive oil, then add the paprika, garlic powder, onion powder, salt, and black pepper. Toss again until all the fries are evenly seasoned.
Spread the fries in a single layer on the prepared baking sheet. Leave a little space between them so they roast instead of steam. Use two baking sheets if needed.
Bake for 15 minutes, then remove the tray and flip the fries carefully.
Return the tray to the oven and bake for another 12 to 15 minutes, or until the fries are tender and lightly crisped around the edges.
While the fries bake, make the sauce. In a small bowl, combine the yogurt, chopped cilantro, lemon juice, minced garlic, salt, black pepper, and olive oil. Stir until smooth and well blended.
Taste the sauce and adjust the lemon or salt if needed.
Serve the sweet potato fries hot with the cilantro yogurt sauce on the side for dipping.
Servings and timing
This recipe makes 4 servings.
Prep time: 15 minutes
Cook time: 27 to 30 minutes
Total time: 42 to 45 minutes
Variations
For a spicier version, add 1/4 teaspoon cayenne pepper to the seasoning mix or stir a little chili powder into the yogurt sauce.
For a smokier flavor, replace the regular paprika with smoked paprika.
You can also add grated lemon zest to the cilantro yogurt sauce for a brighter finish.
If you want a slightly different herb profile, you can use part cilantro and part parsley in the sauce.
To make the fries even more savory, sprinkle them with a little grated Parmesan right after baking.
Storage/Reheating
Store leftover fries in an airtight container in the refrigerator for up to 3 days. Keep the cilantro yogurt sauce in a separate covered container in the refrigerator for up to 3 days as well.
To reheat the fries, place them on a baking sheet in a 400°F (200°C) oven for 8 to 10 minutes, or until heated through and slightly crisp again. You can also reheat them in an air fryer for a few minutes for better texture.
Avoid microwaving the fries if possible, since they can become soft. The sauce does not need reheating; just stir it before serving.
FAQs
Can I make these sweet potato fries in an air fryer?
Yes, you can cook them in an air fryer. Arrange them in a single layer and cook at 380°F to 400°F, shaking the basket halfway through, until they are tender and crisp on the edges.
Why are my sweet potato fries not crispy?
Sweet potatoes naturally contain more moisture than regular potatoes, so they do not become as crisp as deep-fried fries. Using cornstarch, drying them well, and spreading them out on the tray helps improve the texture.
Do I have to peel the sweet potatoes?
No, you can leave the skin on if you prefer. Just wash and scrub them very well before cutting.
Can I make the cilantro yogurt sauce ahead of time?
Yes, the sauce can be made a day in advance. Store it covered in the refrigerator and stir before serving.
What type of yogurt works best for the sauce?
Plain regular yogurt or plain Greek yogurt both work well. Greek yogurt will give you a thicker, creamier sauce.
Can I freeze sweet potato fries?
They are best fresh, but you can freeze cooked fries after cooling them completely. Reheat them in the oven or air fryer to bring back some texture.
What can I serve with sweet potato fries and cilantro yogurt sauce?
They pair well with grilled chicken, wraps, sandwiches, burgers, rice bowls, or roasted vegetables.
Can I use dried cilantro instead of fresh?
Fresh cilantro is best for the sauce because it gives the brightest flavor. Dried cilantro will not give the same result.
How do I cut the fries evenly?
Use a sharp knife and slice the sweet potato into planks first, then cut the planks into thin sticks. Keeping the pieces the same size helps them cook evenly.
Can I make this recipe dairy-free?
Yes, you can use a plain dairy-free yogurt alternative in the sauce. Choose one with a mild flavor and thick texture for the best result.
