Prepare the Oven and Baking Dish:

• Preheat your oven to 375°F (190°C).

• Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of oil.

Coat the Chicken:

• Pat the chicken breasts dry with paper towels.

• Evenly spread mayonnaise over both sides of each chicken breast. This helps keep the meat moist during baking.

Prepare the Breading Mixture:

• In a shallow bowl or plate, combine the ranch dressing mix, seasoned breadcrumbs, and grated Parmesan cheese.

Bread the Chicken:

• Dredge each mayonnaise-coated chicken breast in the breadcrumb mixture, pressing gently to ensure the coating adheres well.

• Place the coated chicken breasts in the prepared baking dish.

Bake:

• Bake in the preheated oven for 25-30 minutes, or until the chicken is cooked through and the coating is golden brown. The internal temperature should reach 165°F (74°C) when measured with a meat thermometer.

Serve:

• Remove the chicken from the oven and let it rest for a few minutes.

• Serve warm alongside your favorite side dishes.
