Ingredients

4 boneless, skinless chicken breasts, cooked and chopped or shredded
2 cups cooked pasta (penne, rotini, or elbow) or rice
1 cup grated Parmesan cheese, divided
1 cup shredded mozzarella cheese
1 can (10 oz) cream of mushroom soup (or cream of chicken soup)
½ cup sour cream or Greek yogurt
½ cup milk
2 cloves garlic, minced
1 teaspoon dried Italian herbs (oregano, basil, thyme)
Salt and black pepper to taste
½ cup breadcrumbs (optional, for topping)
2 tablespoons butter, melted (for breadcrumb topping)

Optional Add-Ins:

1 cup steamed broccoli or spinach
½ cup sautéed mushrooms or bell peppers
Red pepper flakes for a bit of heat

Step-by-Step Instructions

1. Preheat the Oven

Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly with cooking spray or butter.

2. Prepare the Creamy Sauce

In a medium bowl, combine cream of mushroom soup, sour cream, milk, garlic, Italian herbs, salt, and pepper. Mix until smooth.

3. Assemble the Casserole

Layer the cooked pasta or rice evenly in the bottom of the baking dish.
Add the chopped or shredded chicken on top.
Pour the creamy sauce over the chicken and pasta, spreading it evenly.
Sprinkle ½ cup Parmesan and mozzarella cheese over the top.

If using vegetables, layer them between chicken and sauce or mix directly with pasta before adding sauce.

4. Add Topping (Optional)

In a small bowl, mix breadcrumbs with melted butter.
Sprinkle evenly over the cheese layer for a crunchy topping.
Finish with the remaining ½ cup Parmesan cheese.

5. Bake the Casserole

Bake uncovered for 25–30 minutes, or until the casserole is bubbling and the top is golden brown.
For extra browning, switch to broil for 2–3 minutes at the end (watch closely).

6. Serve

Let casserole rest for 5 minutes before serving. This allows it to set slightly and makes serving easier.

Tips for Perfect Parmesan Chicken Casserole

Use cooked chicken: Rotisserie chicken works perfectly for a quick meal.
Customize vegetables: Add your favorites for more flavor and nutrition.
Avoid overbaking: Prevents the cheese from drying out.
Mix breadcrumbs with melted butter: Ensures a crunchy, golden topping.
Use freshly grated Parmesan: Provides the best flavor and melts beautifully.

Variations

1. Chicken and Broccoli Casserole

Add 1 cup steamed broccoli to the pasta layer before pouring sauce.

2. Spicy Parmesan Chicken

Add red pepper flakes or a dash of hot sauce to the creamy sauce for a kick.

3. Low-Carb Version

Replace pasta with cauliflower rice or omit completely for a gluten-free, lower-carb casserole.

4. Extra Cheesy

Mix extra mozzarella or cheddar into the sauce for a gooey, melty casserole.

Serving Suggestions

Pair with a fresh green salad or roasted vegetables
Serve with garlic bread or warm dinner rolls
Add a squeeze of lemon for brightness

Storage & Reheating

Refrigeration: Store leftovers in an airtight container for 3–4 days.
Freezing: Freeze the casserole before baking or after baking for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating: Reheat in the oven at 350°F (175°C) until warmed through, about 15–20 minutes. Microwave works for single servings but may soften topping.
