Kosher saltoptional as most frozen fries come pre-seasoned
Instructions
Coat your air fryer with nonstick spray (if using). Place the fries in a single layer in your air fryer basket—they can touch at the sides a bit but shouldn't be piled on top of each other; if needed, cook them in batches. If you'd like to keep the fries warm in the oven between batches, preheat your oven to 250°F.
For straight cut, crinkle cut, or steak fries: Air fry at 375°F for 9 to 11 minutes. For waffle or shoestring fries: Air fry at 360°F for 8 to 11 minutes. Shake the basket a few times throughout, and cook until the fries are hot and crisped to your liking. The time will vary depending upon the thickness of the fry, your air fryer model, and the brand of fries (keep an eye on them towards the end—I found crinkle fries didn't darken much and got over cooked the most easily).
Keep the air fryer frozen fries warm on a baking sheet in the oven, or enjoy them immediately with a pinch of salt to taste.
Notes
For the most accurate nutritional information, consult your package of frozen French fries.
TO STORE: Transfer leftover fries to an airtight storage container and refrigerate for up to 3 days. (I don’t recommend re-freezing leftover fries.)
TO REHEAT: Reheat the fries in the air fryer at 375ºF until they’re warmed through. This should take just a few minutes.
