Prepare the Chicken:
Slightly freeze the chicken breasts for about 30 minutes to make slicing easier. Using a sharp knife or mandoline, slice the chicken into very thin, even pieces (about ⅛ inch thick).

Dry the Chicken:
Lay the slices between paper towels and gently press to remove any excess moisture.

Season:
In a large bowl, toss the chicken slices with olive oil, garlic powder, onion powder, smoked paprika, black pepper, and sea salt until evenly coated.

Preheat Oven or Air Fryer:
Preheat your oven to 300°F (150°C) or your air fryer to 280°F (140°C).

Arrange:
Lay the chicken slices in a single layer on a parchment-lined baking sheet or in an air fryer basket. Make sure they are not overlapping.

Cook:
Bake for 20–30 minutes or air fry for 15–20 minutes, flipping halfway through, until golden brown and crispy. Watch closely after 15 minutes to prevent burning.

Cool:
Transfer the cooked chips to a wire rack and let them cool completely. They will crisp up even more as they cool.

Serve and Enjoy:
Enjoy immediately or store in an airtight container for a crispy snack anytime!
