These oven-baked cornflake chicken nuggets are coated in a crunchy, savory crust made with cornflakes, panko, and Parmesan. A seasoned flour-and-egg coating helps the crisp crumbs cling to tender chicken, while a splash of pickle brine adds a little tang. Serve them hot with your favorite dipping sauce for an easy family-friendly meal or snack.
Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper. For extra crispness, set a wire rack on the baking sheet if you have one.
In a wide, shallow bowl, stir together the flour, garlic powder, onion powder, cayenne, 1 teaspoon salt, and 1/2 teaspoon black pepper.
Crack the eggs into a second shallow bowl. Add the pickle juice and beat with a fork until evenly combined.
Add the cornflakes, panko, Parmesan, smoked paprika, garlic powder, and onion powder to a food processor. Pulse for about 15 seconds, until the mixture forms fairly even crumbs, then transfer it to a third shallow bowl.
Season the chicken pieces with 1 teaspoon salt and 1/2 teaspoon black pepper. Working with a few pieces at a time, coat the chicken in the flour mixture and shake off the excess. Dip each piece in the egg mixture, then press it into the cornflake mixture so the crumbs adhere on all sides. Arrange the coated pieces on the prepared baking sheet.
Bake for 20–25 minutes, flipping the nuggets about halfway through. They are ready when golden and crisp and the thickest pieces reach an internal temperature of 165°F (74°C). Serve hot with your favorite dipping sauce.
