Preheat your oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
In a large bowl, mix together the breadcrumbs, Parmesan cheese, garlic powder, onion powder, paprika, salt, and black pepper.
In another bowl, whisk together the eggs and Dijon mustard until well combined.
Dip each piece of chicken into the egg mixture, allowing any excess to drip off, then coat it in the breadcrumb mixture, pressing gently to adhere. Place the coated chicken nuggets on the prepared baking sheet.
Drizzle the olive oil over the chicken nuggets to help them crisp up while baking.
Bake in the preheated oven for 15-20 minutes, or until the chicken is cooked through and the nuggets are golden brown and crispy.
Let the nuggets cool for a few minutes before serving.
