Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or lightly grease it with cooking spray.

In a large mixing bowl, combine the breadcrumbs, grated Parmesan cheese, garlic powder, smoked paprika, onion powder, dried oregano, salt, and black pepper.

In a separate bowl, toss the chicken pieces with olive oil until evenly coated.

Working in batches, coat each piece of chicken in the breadcrumb mixture, pressing gently to adhere the coating. Place the coated chicken bites on the prepared baking sheet, ensuring they are in a single layer and not touching.

Lightly spray the tops of the chicken bites with cooking spray. This helps them crisp up in the oven.

Bake in the preheated oven for 18-22 minutes, or until the chicken bites are golden brown and cooked through (internal temperature should reach 165°F/74°C).

Optional: Garnish with chopped fresh parsley before serving.

Serve warm with your favorite dipping sauce, such as ranch, honey mustard, or barbecue sauce.
