Step 1: Preheat your oven to 4000F (2000C). Line a baking sheet with parchment paper or foil for easy cleanup.
Step 2: Pat the chicken breasts thoroughly dry with paper towels. This crucial step helps the coating adhere and ensures a crispier result.
Step 3: In a medium bowl, combine the mayonnaise, grated Parmesan cheese, garlic powder, onion powder, paprika, black pepper, and salt. Mix until all ingredients are well incorporated and form a thick paste.
Step 4: Place each dried chicken breast into the mayonnaise mixture, ensuring it is fully and evenly coated on all sides. You can use your hands or a spoon for this.
Step 5: Arrange the coated chicken breasts on the prepared baking sheet, leaving a little space between each piece to allow for even cooking and crisping.
Step 6: Bake for 20-25 minutes, or until the chicken is cooked through and reaches an internal temperature of 1650F (740C) and the Parmesan crust is golden brown and bubbly. Cooking time may vary based on the thickness of your chicken breasts.
Step 7: Remove from the oven, garnish with fresh chopped parsley if desired, and serve immediately with your favorite side dishes. Enjoy your perfectly juicy and crispy Mayo Parmesan Chicken!
