Tender, juicy chicken breasts baked in a creamy, savory coating with garlic, herbs and Parmesan. The chicken stays incredibly moist while the top becomes beautifully golden.

Ingredients

Chicken

4 boneless, skinless chicken breasts — about 700–800 g
1 tablespoon olive oil
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon garlic powder
½ teaspoon onion powder
1 teaspoon dried Italian seasoning
1 tablespoon fresh rosemary, chopped

Creamy Topping

½ cup mayonnaise
½ cup sour cream
½ cup freshly grated Parmesan cheese
2 cloves garlic, minced
½ teaspoon garlic powder
½ teaspoon paprika
½ teaspoon Italian seasoning
1 tablespoon fresh rosemary, finely chopped
2 tablespoons melted butter

Optional Garnish

Fresh rosemary
Chopped parsley
Extra Parmesan

Instructions

Preheat the oven to 375°F (190°C).
Prepare the chicken.
Pat the chicken breasts dry with paper towels. If the breasts are very thick, gently pound them to an even thickness so they cook evenly.
Season the chicken.
Rub both sides with olive oil, then season with salt, black pepper, garlic powder, onion powder and Italian seasoning.
Make the creamy topping.
In a bowl, combine mayonnaise, sour cream, Parmesan, minced garlic, garlic powder, paprika, Italian seasoning and chopped rosemary.
Arrange the chicken.
Lightly grease a baking dish and place the seasoned chicken breasts inside in a single layer.
Add the topping.
Spread the creamy Parmesan mixture generously over the top of each chicken breast.
Add butter and rosemary.
Drizzle the melted butter over the chicken and sprinkle with fresh rosemary.
Bake.
Bake uncovered for approximately 25–35 minutes, depending on the thickness of the chicken.
Brown the top.
For a beautifully golden finish, place the chicken under the broiler for 1–2 minutes at the end. Watch it closely.
Check doneness.
The thickest part of the chicken should reach 165°F (74°C).
Rest before serving.
Remove from the oven and let the chicken rest for 5 minutes before serving. Spoon some of the flavorful juices from the dish over the chicken.

💡 Tips for Extra-Juicy Chicken

Don’t overbake the chicken; use a meat thermometer for the most reliable result.
Pound very thick chicken breasts to an even thickness.
Let the chicken rest after baking so the juices redistribute.
Freshly grated Parmesan melts better and gives more flavor.
Add a little chicken broth to the bottom of the baking dish if you want extra pan juices.

❓ Q&A

Can I use chicken thighs?

Yes. Boneless, skinless chicken thighs work very well and tend to be naturally juicy. Cooking time may vary.

Can I use Greek yogurt instead of mayonnaise?

Yes. Plain Greek yogurt can replace some or all of the mayonnaise for a lighter, higher-protein topping.

Can I prepare this ahead of time?

Yes. Season the chicken and prepare the topping several hours ahead. Keep refrigerated until you’re ready to bake.

How do I know when it’s done?

The thickest part should reach 165°F (74°C). Avoid relying only on the color of the chicken.

Why is my chicken dry?

Usually because it was cooked too long or the breasts were very thin. Start checking the internal temperature before the estimated cooking time is finished.

Can I freeze it?

Yes. Allow the cooked chicken to cool completely, portion it into airtight containers and freeze. Thaw overnight in the refrigerator and reheat gently.
