Prep the chicken: Pat the chicken pieces dry with paper towels.
Drying helps the coating stick and ensures a crisp finish.
Preheat the air fryer: Set it to 390°F (200°C) for 5 minutes so the basket is hot when the nuggets go in.
Make the egg wash: In a medium bowl, whisk the egg with the mayonnaise until smooth. This combo clings to the chicken better than egg alone.
Mix the coating: In a separate shallow dish, combine crushed pork rinds, almond flour, Parmesan, smoked paprika, garlic powder, onion powder, salt, and pepper. Stir well to evenly distribute the spices.
Coat the chicken: Add the chicken pieces to the egg-mayo mixture and toss to coat.
Shake off excess, then dredge in the dry mixture, pressing gently so the crumbs adhere.
Oil the basket: Lightly spray the preheated air fryer basket with avocado oil. This helps prevent sticking and promotes browning.
Arrange and spray: Place nuggets in a single layer with a little space between each. Lightly mist the tops with oil spray for extra crispiness.
Air fry, flip, finish: Cook at 390°F (200°C) for 8–10 minutes, flipping halfway and lightly spraying again.
Nuggets are done when the coating is golden and an instant-read thermometer inserted into a piece reads 165°F (74°C).
Season and rest: Sprinkle with a pinch of salt while hot. Let rest 2 minutes so the crust sets before serving.
Serve: Pair with sugar-free ketchup, ranch, mustard, or buffalo sauce. Add a side salad, roasted veggies, or cauliflower fries for a full meal.
