Ingredients

Scale

4 boneless, skinless chicken breasts (approximately 2 pounds)

1 cup full-fat sour cream

1 cup shredded mozzarella cheese

1/2 cup grated Parmesan cheese, freshly grated

1 tablespoon cornstarch

1 teaspoon dried oregano

1 teaspoon dried basil

1 teaspoon garlic powder

1/2 teaspoon salt

1/2 teaspoon freshly ground black pepper

Cooking spray for the baking dish

Fresh parsley, chopped (optional, for garnish)

Instructions

1. Preheat the oven to 375°F and lightly coat a 9×13-inch baking dish with cooking spray.

2. Slice each chicken breast horizontally to create thinner cutlets, then arrange them in a single layer in the prepared baking dish and season both sides with salt and pepper.

3. In a medium bowl, whisk together the sour cream, 1/4 cup of the Parmesan cheese, cornstarch, oregano, basil, garlic powder, salt, and pepper until smooth and well combined.

4. Spread the sour cream mixture evenly over each chicken breast, covering them completely.

5. Sprinkle the shredded mozzarella evenly over the sour cream layer, then top with the remaining 1/4 cup Parmesan cheese.

6. Bake uncovered for 30–45 minutes, depending on the thickness of the chicken, until the internal temperature reaches 165°F and the cheese is bubbly and lightly golden.

7. Remove from the oven and let the cheesy sour cream chicken rest for 5 minutes.

8. Garnish with fresh chopped parsley if desired and serve over rice, pasta, or alongside a simple salad.

Notes

If your chicken breasts are very thick, pound them to an even thickness or slightly increase baking time.

Use freshly grated Parmesan for the best melt and flavor.

Add a pinch of crushed red pepper or smoked paprika to the sour cream mixture for a gentle kick.

Leftovers reheat well; cover and warm in a 325°F oven or in the microwave until heated through.
