Crispy Sweet Potato Fries deliver a seriously addictive crunch that beats traditional french fries without the deep-frying guilt. Perfectly seasoned and baked to golden perfection, these fries make your snack time both delicious and nutritious.


Ingredients

Scale

Main Ingredients:

  • 2 large sweet potatoes

Seasoning and Spices:

  • 1 tsp salt
  • ½ tsp black pepper
  • ½ tsp garlic powder
  • ¼ tsp paprika

Cooking and Binding:

  • 2 tablespoons olive oil
  • ¼ teaspoon cornstarch

Instructions

  1. Heat the oven to 425°F and cover a large baking sheet with parchment paper for easy cleanup.
  2. Thoroughly scrub the 2 large sweet potatoes under cool water, then completely dry them with paper towels.
  3. Slice sweet potatoes into precise ¼-inch thick strips, keeping your cuts uniform and consistent.
  4. Transfer potato strips to a spacious mixing bowl for seasoning.
  5. Pour 2 tbsp olive oil over the potato strips and gently toss until each piece gets a smooth, even coating.
  6. Combine 1 tsp salt, ½ tsp black pepper, ½ tsp garlic powder, ¼ tsp paprika, and ¼ tsp cornstarch in a small bowl.
  7. Sprinkle the seasoning blend across the oiled potato strips and toss until every piece is thoroughly seasoned.
  8. Arrange fries in a single layer on the prepared baking sheet, making sure no pieces touch or overlap.
  9. Slide the baking sheet into the 425°F oven and bake for exactly 15 minutes.
  10. Use tongs to carefully flip each fry, ensuring balanced browning on all sides.
  11. Rotate the baking sheet 180 degrees and continue baking for 10-15 minutes until edges turn golden and crisp.
  12. Check that fries have developed a perfect golden-brown exterior with crispy edges.
  13. Remove from oven and let the fries rest on the baking sheet for 2-3 minutes to maintain their crunch.
  14. Transfer to a serving plate and consume immediately while they’re hot and perfectly crisp.

Notes

  • Pat sweet potatoes completely dry to prevent steaming and ensure maximum crispiness.
  • Cutting uniform fry sizes helps each piece cook evenly and achieve consistent texture.
  • Cornstarch is the secret weapon for creating that extra crispy exterior without deep frying.
  • Spacing fries with no overlap on the baking sheet allows hot air to circulate and produce crunchy results.
