Prep your pan: Heat the oven to 425°F (220°C).
Line a sheet pan with parchment and mist with cooking spray.
Drain the chicken well: Press out extra liquid with a fork or paper towels. Dry chicken gives you crispier nuggets.
Mix the base: In a bowl, combine drained chicken, egg, mayo (or yogurt), shredded cheese, garlic powder, onion powder, paprika, salt, and pepper. Break up chicken so the mixture sticks together but still has some texture.
Set up coating: In a shallow dish, mix bread crumbs with Parmesan and a pinch of salt and pepper. Add parsley or Italian seasoning if you like.
Shape the nuggets: Scoop about 1 tablespoon of the chicken mixture, roll into a ball, then flatten into a nugget shape.
Press each side into the crumb mixture to coat.
Arrange and oil: Place nuggets on the pan with space between. Lightly mist or drizzle with olive oil. This helps them brown.
Bake: Bake 10 minutes, flip, then bake 6–8 more minutes, until golden and crisp. For extra crunch, broil 1–2 minutes at the end, watching closely.
Serve: Let rest 3 minutes.
Serve with ketchup, honey mustard, ranch, or barbecue sauce.
