    1 lb. sweet potatoes, 1 Tbsp. oil, ½ - ¾ tsp. salt, ¼ tsp. paprika, ¼ tsp. garlic powder
  • Cook in the Air Fryer: Place fries in a single layer into the air fryer basket with none of the fries touching.  (If you're using a 6-quart air fryer you'll need to cook the fries in 2 batches in order to have enough room to do this.)* Cook fries for 12-14 minutes, flipping halfway through.
  • Serve the fries with ketchup, Sriracha Mayo, or Remoulade Sauce.

Notes

Prep-Ahead Instructions

You can slice the sweet potatoes into fries the day before to save time.
Storage Directions
Keep leftovers in an airtight container in the fridge for up to 4 to 5 days. It is best to freeze the fries in a single layer on a sheet pan for a few hours. Then, transfer the potatoes to a freezer-safe bag and keep for up to 6 to 7 months. To reheat, pop the sweet potatoes back in the air fryer at 350℉ for about 5 minutes.
Recipe Tips
  • Same size. Cut the fries to a similar size to ensure even cooking and crispiness.
  • A little goes a long way. Toss the potatoes with just enough oil to coat, and not too much.
  • Give 'em space. Place the fries in a single layer, with little to no touching.  Do not overcrowd the air fryer basket.
  • Turnover. Flip the fries halfway through cooking to allow all sides of the fries to crisp up fully.
  • Change it up. Vary the flavors on these potatoes! Try them with Parmesan cheese or Cajun seasoning.
