- Salt, to taste
Instructions
- Step 1: Preheat your air fryer to 400 degrees Fahrenheit.
- Step 2: In a large bowl, toss the sweet potato strips with olive oil until evenly coated. Add the cornstarch and toss again until absorbed.
- Step 3: Arrange the fries in a single layer in the air fryer basket. Leave space between each fry for even cooking. You may need to cook in batches.

Tips & Variations
- For extra crispiness, soak the cut sweet potatoes in cold water for 30 minutes before cooking and pat dry thoroughly.
- Try seasoning with smoked paprika, garlic powder, or cinnamon for added flavor.
- Use tapioca starch instead of cornstarch to keep the recipe Paleo and Whole30 compliant.
Storage
Store leftover fries in an airtight container in the refrigerator for up to 2 days. Reheat in the air fryer at 350 degrees Fahrenheit for 3-5 minutes to restore crispiness. Avoid microwaving to prevent sogginess.
