How to Make Sweet Potato Fries
-
Peel and Slice: Begin by peeling the sweet potatoes and cutting them into uniform 1/4-inch sticks. This consistency is key to ensuring even cooking and a perfectly crispy texture.
-
Soak in Cold Water: Place the cut fries in a bowl of ice-cold water and let them soak for at least 30 minutes. This step removes excess surface starch, helping achieve that perfect crunch!
-
Drain and Dry: After soaking, drain the fries and pat them completely dry using a kitchen towel. Removing moisture is crucial, as this prevents them from steaming in the oven.
-
Coat with Cornstarch: In a large bowl, toss the dried fries with cornstarch until they’re evenly coated. This light coating is key to achieving that delightful crispness without deep frying.
-
Preheat the Oven: Preheat your oven to 220°C (425°F) and line your baking sheets with parchment paper. This allows the fries to bake evenly while preventing sticking.
-
Mix with Oil and Seasoning: In a large mixing bowl, combine the fries with avocado oil, smoked paprika, garlic powder, and half of the sea salt. Toss well until the fries are perfectly coated with the seasoning mixture.
-
Arrange on Baking Sheets: Spread the fries out on the prepared baking sheets, ensuring they have ample space between them. This allows for optimal air circulation and better crispiness.
-
Bake to Perfection: Place the baking sheets in the oven and bake for 20-25 minutes. Flip the fries halfway through, until the edges are golden brown and the coating is rigid and crunchy.
Optional: For an extra burst of flavor, sprinkle with fresh herbs or Parmesan cheese right before serving.

How to Store and Freeze Sweet Potato Fries
-
Room Temperature: Best enjoyed fresh, but if you have leftovers, they can be kept at room temperature for about 1–2 hours before they start to lose their crispiness.
-
Fridge: Store any leftover sweet potato fries in an airtight container in the fridge for up to 3 days. This helps maintain their texture and flavor.
-
Freezer: If you want to save some for later, you can freeze the fries in a single layer on a baking sheet before transferring to a freezer-safe bag. They can be frozen for up to 2 months.
-
Reheating: For the best results, reheat fries in the oven at 220°C (425°F) for about 10-15 minutes until crisp. Avoid microwaving, as it can make them soggy.
Expert Tips for Sweet Potato Fries
- Soak Time Matters: Always soak your sweet potato fries for at least 30 minutes to remove surface starch; skipping this step can lead to soggy fries.
- Thorough Drying: Make sure to pat the fries dry completely after soaking to prevent steaming, which can ruin their crispy texture.
- Airflow is Key: Leave at least 1/2 inch of space between fries on the baking sheets; crowding them can result in uneven baking and less crispness.
- Batch Baking: If you’re making a large batch, consider using two pans; this prevents overcrowding and ensures all fries get crispy, enhancing your homemade experience.
- Monitor Baking: Keep an eye on the fries while baking; every oven is different, and a few extra minutes can make the difference between perfect and burnt.

Sweet Potato Fries Recipe FAQs
What type of sweet potatoes should I use?
Absolutely! For the best results, opt for large, firm sweet potatoes that aren’t overly moist. Look for those with smooth skin and a vibrant color; avoid any that have dark spots all over, which may indicate spoilage.
How should I store leftover fries?
To preserve their deliciousness, store any leftover sweet potato fries in an airtight container in the fridge for up to 3 days. Make sure they’re completely cooled before sealing them up to avoid condensation which can make them soggy.

What if my fries don’t come out crispy?
If your fries aren’t crispy, a few factors might be at play. Ensure you soaked them for enough time—at least 30 minutes—and drained them thoroughly before tossing in cornstarch. Also, be mindful of overcrowding on the baking sheet; ensure there’s at least 1/2 inch of space between each fry to allow proper air circulation. If they still lack crispness, you can try increasing the oven temperature by a few degrees.
