With about 20 minutes of prep time, this recipe is a smart choice for a weeknight dinner. It comes together quickly, especially when using leftover cooked chicken, and bakes into a satisfying meal the whole family can enjoy.
Why will you love Chicken Parmesan Casserole?
Cooking the pasta al dente is key. Because it continues to cook in the oven, starting with slightly undercooked pasta prevents it from becoming soft and mushy.
Using pre-cooked chicken is a major time-saver. Rotisserie chicken or any leftover cooked chicken works well and makes this dish fast enough for a weeknight.
Making a separate buttered breadcrumb topping ensures it gets golden and crunchy. Mixing breadcrumbs directly into the casserole can make them steam instead of toast.
Chicken Parmesan Casserole Ingredients

• Pasta: Rotini, penne, or ziti are great choices. Any short pasta with ridges will hold the sauce nicely.
• Chicken: Use leftover roasted or rotisserie chicken to save time. You can also quickly poach and shred two chicken breasts.
• Marinara Sauce: Your favorite jarred marinara sauce is convenient for this recipe. Choose one with a flavor you already enjoy.
• Panko Breadcrumbs: Panko creates a lighter, crispier topping than regular breadcrumbs. You can substitute with regular, but the texture will be denser.
• Diced Tomatoes: These add extra texture and bright tomato flavor, but you can leave them out if you prefer a smoother sauce.

How to Make Chicken Parmesan Casserole
Step 1: Prepare Pasta and Topping
First, get your oven preheating to 375°F (190°C) and boil the pasta until it’s al dente. While it cooks, mix together the ingredients for the crunchy topping: Panko, Parmesan, melted butter, parsley, and garlic powder. Set the topping aside for later.
Step 2: Assemble the Casserole
Once the pasta is drained, combine it in a large bowl with most of the marinara sauce, the cooked chicken, diced tomatoes, and Italian seasoning. Stir everything together until the pasta and chicken are fully coated in sauce.

Step 3: Layer and Bake
Pour the pasta mixture into your baking dish. Top it with the rest of the marinara sauce, a generous layer of mozzarella, and finally, the breadcrumb mixture. Bake for about 25 minutes until the sauce is bubbling and the top is golden.

What to Serve with Chicken Parmesan Casserole
Serve this casserole with a simple green salad with a vinaigrette dressing or a side of steamed green beans.
Helpful Tricks for Chicken Parmesan Casserole
Food Safety: Ensure the casserole is heated through. Since it contains pre-cooked poultry, the internal temperature should reach 165°F (74°C) when checked with a food thermometer.
This recipe is a great way to use up leftover rotisserie or roasted chicken. If you don’t have cooked chicken, you can poach two chicken breasts and shred them.
You can assemble the casserole without the topping up to one day ahead. Cover and refrigerate, then add the topping just before baking. You may need to add 5-10 minutes to the baking time.
How to Store and Freeze Chicken Parmesan Casserole
Store leftovers in an airtight container in the refrigerator for up to 3 days. You can also freeze the baked casserole for up to 2 months. Reheat individual portions in the microwave or bake the casserole, covered, at 350°F (175°C) until heated through.
