This easy chicken mozzarella bake comes together in 45 minutes with just 7 ingredients. Tender chicken, rich marinara, and melted cheese, perfect weeknight dinner!
Begin the chicken recipe by preheating the oven to 375 degrees F. Evenly season both sides of each 1 ½ pounds chicken breast with ½ teaspoon salt and ½ teaspoon ground black pepper. Set aside.
Using a large skillet on the stovetop over medium-high heat, add the 2 tablespoons olive oil and allow it to warm thoroughly. To make this a one dish recipe, use an oven-safe skillet. Add the chicken and allow it to cook undisturbed for 3-4 minutes. Flip each piece of chicken to the other size and allow it to cook for another 2 minutes.
Turn off the heat, the chicken will not be fully cooked at this point and that is completely fine. Transfer the cooked chicken to a separate baking dish/casserole dish or leave it in the oven proof skillet.
Evenly top the chicken with the 25 ounces pasta sauce and use a spoon to spread it in an even layer over the chicken.
Top the sauce evenly with the grated ½ cup Parmesan cheese.
Place into the oven and allow it to bake for 15 minutes.
Carefully remove the baking dish or skillet from the oven and spread the 1 ½ cups shredded mozzarella cheese in an even layer. Return to the oven and continue baking for an additional 10 minutes until the cheese has melted and is bubbly.
If you prefer to have the top brown a little more, place under the broiler on high heat for a few minutes until the mozzarella cheese has lightly browned.
Carefully remove the chicken mozzarella bake from the oven and allow it to cool for about 5 to 10 minutes before serving. Pair it with your favorite pasta or enjoy it with some crusty bread. Enjoy!
