In a bowl, combine the chicken pieces with buttermilk, salt, pepper, garlic powder, and paprika. Mix well and let marinate in the refrigerator for at least 30 minutes (or up to 2 hours).
1 pound boneless, skinless chicken breasts, 1/2 cup buttermilk, 1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, 1/4 teaspoon paprika
In a separate bowl, whisk together the flour, cornstarch, salt, pepper, garlic powder, paprika, and baking powder.
1 cup all-purpose flour, 1/4 cup cornstarch, 1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, 1/4 teaspoon paprika, 1/4 teaspoon baking powder
Take each marinated chicken piece and dredge it thoroughly in the breading mixture, ensuring it's fully coated. Press the breading lightly to adhere.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper and lightly spray with vegetable oil. Arrange the breaded chicken nuggets on the prepared baking sheet.
Bake for 15-20 minutes, flipping halfway through, until golden brown and cooked through. The internal temperature should reach 165°F (74°C).
