For extra crispiness, avoid overcrowding the air fryer basket and cook the chicken bites in batches if needed so they brown instead of steam. If your almond flour is coarse, pulse it in a food processor for a finer texture that mimics traditional breadcrumbs more closely. Chicken thighs can be used instead of chicken breast for richer flavor and added fat, just trim and cut them into similar sized pieces for even cooking. To meal prep, cool leftovers completely, then store them in an airtight container in the refrigerator for up to three days or freeze in a single layer before transferring to a freezer bag. Reheat in the air fryer at 360°F until warmed through and crisp, adding fresh mozzarella only at the end if desired. Always confirm the nutrition of your marinara and cheese choices, since carb counts can vary widely between brands.
