Preheat the oven to 425°F and line a baking sheet with parchment paper.
Mix ground chicken, egg, breadcrumbs, garlic powder, paprika, salt, and pepper until just combined.
Mix the coating breadcrumbs with Parmesan and olive oil in a shallow bowl.
Shape the chicken mixture into small nuggets about 1/2 inch thick.
Coat each nugget thoroughly in the breadcrumb mixture and place on the prepared sheet.
Bake for 12–15 minutes, flipping halfway through, until golden and cooked through.
Check that the thickest nugget reaches 165°F.
Let the nuggets rest for a few minutes before serving with your favorite dipping sauce.
