Preheat your oven to 375°F (190°C). While it’s heating up, grab a 9 by 13-inch baking dish and give it a light coating with cooking spray. This helps prevent the chicken from sticking to the dish as it cooks.

In a small mixing bowl, combine your sour cream, garlic powder, seasoned salt, and a cup of the shredded Parmesan cheese. Remember to stir the mixture well until it’s thoroughly combined. This creamy mixture will give your chicken its irresistible melt-in-your-mouth texture and savory flavor.

Lay your chicken breasts flat in the baking dish. It’s okay if they touch, but try not to overlap them. Now, evenly distribute the creamy cheese mixture you prepared over each chicken breast. Ensure each piece of chicken is well-covered. This acts as a delicious blanket that keeps the chicken moist and flavors it beautifully as it bakes.

Sprinkle the remaining half cup of shredded Parmesan cheese over the top of your chicken breasts, adding an extra layer of cheesy goodness.

Finish off by evenly sprinkling the freshly ground black pepper over the top of your chicken. This will provide a hint of heat to balance the richness of the cheese and sour cream.

Bake your chicken in the preheated oven for 25 to 30 minutes, or until the chicken is fully cooked through. For a beautiful golden-brown finish, turn on your broiler for the final 5 minutes. Keep a close eye on it, though, as it can easily go from golden to burnt in a matter of seconds under the broiler!

Voila! You now have a batch of succulent savory chicken, perfect for a quick weeknight dinner or a fancy weekend feast. Serve it alongside mashed potatoes and steamed vegetables for a complete meal. This dish is also keto-friendly, making it a great choice for those following a low-carb diet.
