Begin by adding frozen tater tots to the air fryer basket in an even layer. The tots can touch but not overlap.
Spray them lightly with cooking oil and season with salt and pepper to taste.
Air fry the tater tots at 400°F for 5 minutes.
Open the basket and shake the tots to turn them over for even, crispy cooking. Then air fry for another 5-7 minutes or until your tots are golden and crisp.
Remove the tater tots from the basket and set them aside.
Then wipe the basket clean and line it with parchment paper, a silicon basket, or a paper air fryer liner.
Place the tater tots back in the lined basket and top with warm chili and shredded cheese.
Air fry for 5 minutes at 350°F or until the cheese is melted and bubbly.
