Start by air-frying chicken nuggets according to package directions (typically 12-15 minutes at 400°F), checking them about 2 minutes early to avoid overcooking. They should reach an internal temperature of 165°F. While they're cooking, combine cottage cheese, marinara sauce, half of the mozzarella, Italian seasoning, and garlic powder in a microwave-safe bowl.

Microwave the cottage cheese mixture on high for 1 minute, stirring halfway through. The mixture should be warm throughout with small bubbles forming around the edges.

Cut the cooked chicken nuggets into bite-sized pieces and stir them into the warm cottage cheese mixture until well coated.

Sprinkle remaining mozzarella on top and microwave for 30 seconds, or until cheese is completely melted and starting to turn golden. Stir once more before serving.
