Air Fryer Butternut Squash Fries

  • Author: Agnieszka
  • Total Time: 30 minutes
  • Yield: 4 servings 1x


Air Fryer Butternut Squash Fries are a fabulous low-carb alternative to potato or sweet potato French fries. They are crispy on the outside, perfectly seasoned and soft and creamy inside.



1 butternut squash
3 tablespoons corn starch, tapicoca flour or arrowroot powder
2-3 tablespoons olive oil
½ teaspoon salt
½ teaspoon freshly ground black pepper
½ teaspoon garlic powder
½ teaspoon paprika

Garlic Thyme Aioli
½ cup mayonnaise
1 tablespoon lemon juice
1 garlic clove, crushed or minced
¼ teaspoon fresh or dried thyme (leaves only)
¼ teaspoon onion powder
¼ teaspoon smoked paprika
Salt and pepper to taste


  1. Peel butternut squash and slice it into ¼ inch thick slices. Then cut into thin fries. Try to make them uniform so they cook at the same time. I used only the long part of the squash and ended up with 1.5 lbs of raw fries.
  2. Dust the fries with cornstarch or tapioca flour until evenly coated. See note below on using a colander.
  3. Now add olive oil and all the spices and toss to coat.
  4. Preheat your air fryer to 400 degrees Fahrenheit for a couple minutes, then add the fries and air fry for 15 minutes shaking the basket every 5 minutes. For crispy fries, cook them in two or more batches.

Garlic Thyme Aioli
Mix mayo, lemon juice, thyme and all the spices in a small bowl.



Use only the long part of butternut squash for uniform looking straight fries. When shopping for squash, pick one with a long “neck” part. You can save the rounded part for another dish. My butternut squash was large and yielded 1.5 lbs fries (before cooking).

If you like crispier fries, you can cook them a couple minutes longer.

Air fryer sizes vary so you may want to cook your fries in a couple batches. Mine is a 7-quart basket-style air fryer by GoWise.

Nutritional value below is for butternut squash fries only (no dipping sauce).

For paleo version of the fries use tapioca flour or arrowroot powder for coating the fries.
