Preheat the air fryer to 380°F.
Pat the 1 pound chicken tenders dry with a clean towel or paper towel.
Put the tenders in a bowl, add 2 teaspoons olive oil, and toss until evenly coated.
Sprinkle seasoning salt evenly over both sides of the tenders (no need to measure; season to your preference).
Arrange the tenders in a single layer in the air fryer basket with space between pieces (cook in batches if necessary).
Air-fry at 380°F for 8–10 minutes total, flipping the tenders halfway through (about 4–5 minutes).
Confirm doneness with an instant-read thermometer—internal temperature should reach 165°F.
Remove from the air fryer and let rest 2–3 minutes before serving.
