Step 1:

Preheat your oven to 375°F (190°C) and lightly grease a baking dish large enough to hold all the chicken breasts in a single layer.

Step 2:

In a small mixing bowl, combine the Caesar dressing, sour cream, Parmesan cheese, garlic powder, salt, and pepper. Whisk until the sauce is smooth and well combined.

Step 3:

Place the chicken breasts in the prepared baking dish. Season both sides of the chicken with salt and pepper, ensuring the flavors get locked into the meat.

Step 4:

Pour the Caesar-Parmesan sauce evenly over the chicken breasts, making sure each piece is well coated.

Step 5:

Bake the chicken in the preheated oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C). The sauce should be bubbly and slightly golden on top.

Step 6:

Once the chicken is fully cooked, remove the dish from the oven. Let it rest for 5 minutes to allow the juices to settle.

Step 7:

Garnish with freshly chopped parsley before serving to add a touch of color and freshness.
