Preheat the air fryer to 380°F.
Put 1 pound chicken tenders in a bowl, add 2 teaspoons olive oil, and toss until each tender is evenly coated.
Sprinkle seasoning salt over the oiled tenders to your preference.
Arrange the tenders in a single layer in the air fryer basket (do not overcrowd; cook in batches if needed).
Air-fry for 8–10 minutes total, flipping the tenders halfway through (about 4–5 minutes). Cook until an instant-read thermometer inserted into the thickest part of a tender reads 165°F.
Let the tenders rest 1–2 minutes, then serve.
