Remove all plastic or paper and note any manufacturer directions, especially for raw-meat products.
Preheat the air fryer to 350°F for 3 minutes.
Mist the tortilla very lightly with oil if desired. Place the burrito seam-side up in the basket.
Air fry 8 minutes, turn seam-side down, then cook 5 to 8 minutes more.
Insert a thermometer through one end when safety or a meat filling requires certainty. Otherwise cut carefully and confirm the center is steaming hot.
Rest 2 minutes before biting; the filling can be much hotter than the tortilla.
