Prep the air fryer: Preheat to 400°F (200°C) for about 3–5 minutes. Lightly spray the basket to prevent sticking.
Crush the chips: Add potato chips to a zip-top bag and crush with a rolling pin until fine with a few small bits.
You want a sandy texture with slight crunch. Pour into a shallow dish.
Season the flour: In another shallow dish, mix flour with garlic powder, onion powder, paprika, black pepper, and a small pinch of salt. Stir to combine.
Make the egg wash: In a bowl, whisk eggs and milk until smooth.
Prep the chicken: Pat chicken dry with paper towels.
If using breasts, slice horizontally into cutlets about 1/2 inch thick for even cooking.
Coat the chicken: Dredge each piece in seasoned flour (shake off excess), dip in egg wash, then press firmly into the crushed chips. Make sure every side is well coated. Press the crumbs on so they stick.
Load the basket: Arrange chicken in a single layer in the air fryer, leaving a little space between pieces. Lightly spray the tops with oil to help crisp and color.
Cook: Air fry at 400°F (200°C) for 8–10 minutes for tenders or thin cutlets, flipping halfway and spraying again lightly.
Cook until the internal temperature reaches 165°F (74°C) and the coating is deep golden.
Batch as needed: If making more than fits in one layer, cook in batches to avoid steaming.
Rest and serve: Let chicken rest 3 minutes. Serve with lemon, a drizzle of hot honey, or your favorite dipping sauce.
