Follow these detailed steps for a foolproof cooking experience:

Step 1: Preheat and Prep

• Preheat your oven to 375°F (190°C).
• Lightly grease a 9×13 inch baking dish or line it with parchment paper for easier cleanup.

Step 2: Mix the Coating

• In a medium bowl, combine:
  • 1 cup mayonnaise (or Greek yogurt)
  • 1/2 cup grated Parmesan cheese
  • 1 teaspoon seasoning salt
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder
• Stir until well combined. The mixture should be thick and creamy.

Step 3: Prepare the Chicken

• Place the chicken breasts on a clean cutting board.
• Pat them dry with paper towels. This step is essential to ensure the coating sticks well.
• If the breasts are particularly thick, consider butterflying or pounding them to an even thickness for uniform cooking.

Step 4: Coat the Chicken

• Spread the mayo-Parmesan mixture evenly over the top of each chicken breast.
• Use a spoon or spatula to make sure each piece is thoroughly coated.

Step 5: Bake

• Transfer the coated chicken breasts to the prepared baking dish.
• Bake uncovered in the preheated oven for 35–40 minutes, or until the internal temperature reaches 165°F (74°C) and the top is golden and bubbly.

Step 6: Broil (Optional)

• For a crispier top, switch the oven to broil for the last 2–3 minutes of cooking. Keep a close eye on it to prevent burning.

Step 7: Serve

• Remove the chicken from the oven and let it rest for 5 minutes before serving.
• Garnish with chopped parsley or extra Parmesan if desired.
