This Chicken Parmesan casserole is hearty enough to stand on its own, but it really shines when you give it a few old-fashioned Midwestern companions. A simple green salad with crisp lettuce, red onion, and a tangy vinaigrette helps cut through the richness and adds a little crunch. Buttered egg noodles or a side of spaghetti make good use of any extra sauce in the pan, while garlic bread or warm dinner rolls are perfect for swiping up the last cheesy bits. If you like a more traditional meat-and-potatoes plate, serve it alongside roasted potatoes or a cheesy mashed potato bake. Add a side of steamed green beans or sweet corn—fresh in summer, frozen in winter—and you’ve got the kind of balanced, stick-to-your-ribs supper that feels right at home on a farm table or a cozy kitchen counter.
Simple Baked Chicken Parmesan Casserole
Servings: 6 servings
Ingredients
2 pounds boneless, skinless chicken breasts, cut into 2-inch pieces
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon dried Italian seasoning (or a mix of oregano and basil)
1/2 teaspoon garlic powder
2 cups jarred marinara or pasta sauce
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese
1 cup seasoned Italian breadcrumbs (or plain with a pinch of Italian seasoning and salt)
2 tablespoons olive oil or melted butter
Nonstick cooking spray or a little extra oil for greasing the baking dish
Optional: a handful of fresh basil or parsley, chopped, for serving
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a thin film of oil.
Arrange the raw chicken pieces in an even layer across the bottom of the baking dish. They can be close together, but try not to pile them on top of one another.
Season the chicken evenly with salt, black pepper, Italian seasoning, and garlic powder. This gives the meat good flavor all the way through as it bakes.
Pour the marinara or pasta sauce over the chicken, spreading it gently with the back of a spoon so every piece is covered. You want the chicken nestled under the sauce like it’s tucked in under a blanket.
Sprinkle the shredded mozzarella cheese evenly over the sauced chicken, followed by the grated Parmesan cheese. This will melt and bubble into that familiar Chicken Parmesan topping.
In a small bowl, combine the seasoned breadcrumbs with the olive oil or melted butter, stirring until the crumbs are evenly moistened. This helps them brown and crisp instead of drying out.
Scatter the oiled breadcrumbs evenly over the cheese layer, covering as much of the surface as you can. This will form the crunchy, golden top that makes this casserole so comforting.
Cover the baking dish loosely with foil, tenting it slightly so it doesn’t stick to the cheese and crumbs. Bake covered for 20 minutes to help the chicken cook through gently.
Remove the foil and continue baking for another 20–25 minutes, or until the chicken is cooked through (no pink in the center and juices run clear), the sauce is bubbling around the edges, and the breadcrumb topping is golden brown. Total baking time is usually about 40–45 minutes, depending on the size of your chicken pieces.
Let the casserole rest for 5–10 minutes before serving. This gives the cheese and sauce a chance to settle and makes it easier to scoop. If you like, sprinkle chopped fresh basil or parsley over the top for a little color and freshness before bringing it to the table.
Variations & Tips
For a heartier, more old-fashioned bake, scatter 1–2 cups of cooked pasta (like penne or rotini) in the bottom of the dish before adding the chicken and sauce; just be sure to add an extra 1/2 cup of sauce so it doesn’t dry out. If your family prefers dark meat, you can substitute boneless, skinless chicken thighs for the breasts; they stay very tender and forgiving if you leave the casserole in the oven a few extra minutes. To lighten things up, use part-skim mozzarella and reduce the breadcrumbs to 3/4 cup, or swap half the breadcrumbs for crushed whole-wheat crackers. For a little farmhouse flair, mix a handful of shredded cheddar into the mozzarella for a slightly sharper, more Midwestern flavor. If you like extra crunch, wait until the last 10–15 minutes of baking to add the breadcrumb mixture so it stays very crisp. You can also prepare the dish earlier in the day, cover it tightly, and refrigerate; when baking from cold, add about 10 minutes to the covered baking time and check that the chicken is cooked through before serving. Leftovers reheat well in a low oven, loosely covered with foil, and are excellent spooned over hot noodles or tucked into a toasted hoagie roll for a quick Chicken Parmesan sandwich.
