Heat an air fryer to 400°F.
Place about ½ bag frozen tater tots in a single layer in the basket (they can be touching).
Air fry for 6 minutes.
Shake the basket to toss the tater tots.
Air fry until golden brown and crispy, 4 to 6 minutes more.
Transfer to a serving bowl and repeat air frying the remaining tater tots.
Sprinkle with ¼ teaspoon seasoned salt if desired and toss to combine.
