Creating Gluten-Free Baked Chicken Nuggets can be effortless if you follow these clear steps:

1. Preheat the Oven: Start by preheating your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Prepare the Chicken: Cut the chicken breasts into bite-sized pieces. Ensure they are uniform for even cooking.
3. Mix the Coating: In a bowl, combine gluten-free breadcrumbs, Parmesan cheese, garlic powder, onion powder, paprika, salt, and black pepper.
4. Prepare the Egg Wash: In another bowl, whisk together the eggs and mustard until frothy.
5. Coat the Chicken: Dip each chicken piece first into the egg wash, allowing excess to drip off, then coat with the breadcrumb mixture. Press the breadcrumbs onto the chicken to ensure they stick well.
6. Arrange on Baking Sheet: Place the coated chicken pieces on the prepared baking sheet in a single layer, ensuring they do not touch.
7. Spray with Oil: Lightly spray the tops of the nuggets with cooking spray or olive oil to promote browning.
8. Bake: Place the chicken nuggets in the oven and bake for 25-30 minutes, or until golden brown and the internal temperature reaches 165°F (75°C).
9. Cool Slightly: Remove the nuggets from the oven and allow them to cool for about five minutes before serving.

These steps will lead you to perfectly baked chicken nuggets that are deliciously crunchy and flavorful!
