These crispy air fryer frozen French fries are the easiest way to get golden, crunchy fries at home—no oil and no mess. Perfect as a quick snack or a classic side for burger night, they cook straight from frozen and come out perfectly crisp every time.
2 lb bag frozen French fries (regular or crinkle-cut)
6 tbsp ketchup
2 tsp horseradish
Place the frozen French fries in the air fryer basket in a single layer.
Air fry at 400°F (205°C) for 12 minutes, shaking the basket halfway through for even cooking.
While the fries cook, make the spicy ketchup by mixing the ketchup and horseradish in a small bowl until smooth.
Remove fries from the air fryer once golden and crispy.
Serve hot with spicy ketchup or your favorite dipping sauce.
Don’t overcrowd: Cook in batches if your air fryer is small.
No thawing needed: Cook fries straight from frozen for best texture.
Extra crunch: Add 1–2 extra minutes if you like your fries very crispy.
Season after cooking: Salt or season fries once they’re hot so it sticks better.
