Set your oven to 375°F (190°C) and let it fully preheat while you prep everything else.

Lightly grease a 9x13-inch baking dish with oil or cooking spray. This keeps the chicken from sticking and makes cleanup easier.

Pro Tip: Let your baking dish sit at room temperature for a few minutes before adding cold ingredients—this helps prevent glass or ceramic dishes from cracking in the oven.

Pat your chicken breasts dry with paper towels. Removing excess moisture helps the topping stick better and gives the chicken a nice texture.

Place the chicken breasts in a single layer inside the prepared baking dish.

Pro Tip: If your chicken breasts are super thick, slice them horizontally to create cutlets. This helps them cook faster and more evenly.

In a mixing bowl, combine:

1 cup mayonnaise

1 cup grated Parmesan cheese

1 teaspoon garlic powder

1 teaspoon onion powder

1 teaspoon paprika

½ teaspoon salt

½ teaspoon black pepper

Stir everything together until it's smooth, creamy, and evenly blended.

Pro Tip: Taste the mixture before spreading — feel free to adjust salt or add a pinch of cayenne if you want a bit of heat.

Spoon the creamy mixture evenly over each chicken breast.

Use the back of the spoon or a spatula to spread it out, covering the top fully from edge to edge.

Pro Tip: Don’t worry if some topping slides off while baking — it turns into a delicious sauce at the bottom of the dish.

Place the baking dish in the preheated oven.

Bake uncovered for 35–40 minutes, or until the chicken is cooked through (internal temp should hit 165°F/74°C).

The top should be golden brown and slightly bubbly when it’s ready.

Pro Tip: If the top isn’t browning to your liking, switch on the broiler for the last 1–2 minutes. Keep a close eye so it doesn’t burn!

Remove the dish from the oven and let it rest for 5 minutes — this helps the juices settle and makes the chicken even more tender.

Serve with your favorite sides like mashed potatoes, roasted veggies, or a simple green salad.

Pro Tip: Spoon a bit of that creamy sauce from the bottom of the pan over the chicken when serving — it’s full of flavor!
