Prep the chicken: Pat the tenders dry with paper towels. This helps them brown and prevents steaming.
Season: In a large bowl, toss chicken with oil, garlic powder, onion powder, paprika, salt, and pepper.
Add cayenne if you like heat. Coat evenly.
Preheat the air fryer: Set to 400°F (200°C) for 3 to 5 minutes. A hot basket gives better browning.
Arrange: Place chicken in a single layer in the basket.
Leave a little space between pieces. Work in batches if needed.
Cook: Air fry for 9 to 12 minutes, flipping halfway. Start checking at 8 minutes.
You want lightly browned edges and juicy centers.
Check doneness: Use a meat thermometer. Target 165°F (74°C) at the thickest part.
Rest briefly: Let the tenders sit for 3 minutes before serving to keep juices in.
Finish and serve: Squeeze with lemon, sprinkle herbs, and serve with your favorite keto-friendly sauce.
