Prep the chicken: Pat the chicken tenders dry with paper towels. If using chicken breasts, slice into even strips so they cook at the same rate.
Set up a breading station: In one shallow bowl, beat the eggs and whisk in a spoonful of mayonnaise for extra cling (optional).
In a second bowl, mix almond flour, crushed pork rinds, Parmesan, 1 teaspoon salt, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon smoked paprika, and 1/2 teaspoon black pepper.
Coat the chicken: Dip each piece into the egg mixture, then press into the dry mixture until well coated. Shake off excess and place on a parchment-lined baking sheet or an air fryer tray. Lightly mist with oil spray for maximum crispiness.
Oven method: Bake at 400°F (200°C) for 16–20 minutes, flipping halfway.
For extra crunch, broil for the last 1–2 minutes. Internal temperature should reach 165°F (74°C).
Air fryer method: Air fry at 380°F (193°C) for 10–12 minutes, flipping and lightly spraying halfway, until crisp and cooked through.
Rest and serve: Let the tenders rest for 3–5 minutes to set the coating. Serve with ranch, mustard, or a sugar-free dipping sauce.
