Step 1: Preheat your oven to 375°F (190°C). This ensures that the chicken cooks evenly and that the topping becomes golden brown and bubbly. Prepare your baking dish by lightly greasing it with cooking spray or olive oil. This will prevent the chicken from sticking to the dish and make cleanup easier.
Step 2: In a small bowl, combine the mayonnaise (or Greek yogurt), grated Parmesan cheese, garlic powder, onion powder, paprika, salt, and black pepper. Mix well until all the ingredients are thoroughly combined and form a smooth, creamy mixture. This mixture will be the flavorful coating that keeps the chicken moist and adds a delicious crust.
Step 3: Place the chicken breasts in the prepared baking dish. Make sure they are evenly spaced to allow for proper air circulation and even cooking. If your chicken breasts are particularly thick, you can gently pound them with a meat mallet to even them out. This will help them cook more quickly and evenly.
Step 4: Spread the mayonnaise mixture evenly over the top of each chicken breast. Ensure that each breast is completely covered with the topping, as this will help to lock in moisture and create a flavorful crust. The topping should be about ¼ inch thick.
Step 5: Bake for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and is golden brown on top. Use a meat thermometer to ensure that the chicken is cooked through. Insert the thermometer into the thickest part of the breast, avoiding the bone. The chicken is done when the thermometer registers 165°F (75°C). Remove from oven and let it rest for 5 minutes before garnishing and serving.
