Preheat your air fryer to 370°F (185°C) for about 3-5 minutes.
Place the frozen fries in the air fryer basket, spreading them out into a single layer.
Cook the fries in the air fryer at 370°F (185°C) for 10-12 minutes, shaking the basket halfway through the cooking time for even crisping.
Once the fries are golden brown and crispy, carefully remove them from the air fryer.
Serve immediately.
Notes
Plain frozen potato fries are often gluten-free, but always check the bag: coated, battered, or seasoned fries can contain wheat. Choose fries labeled gluten-free and cook them in a clean air fryer basket that has not been used for breaded foods.For extra crispy fries, cook 1 to 2 minutes longer. If you skip preheating, you may need to add a little cooking time.
