HOW TO MAKE CHICKEN PARMESAN CASSEROLE:
STEP-BY-STEP INSTRUCTIONS:
1. Preheat and Prepare
Start by preheating your oven to 375°F. Spray a 9×13-inch casserole dish with a little nonstick spray to make clean-up a breeze later.
2. Layer the Chicken
Spread your cooked, diced or shredded chicken evenly across the bottom of the dish. I love using rotisserie chicken for this—it’s tender, flavorful, and saves so much time.
3. Sauce it Up
Pour the marinara sauce over the chicken. Give it a gentle stir right in the dish so every piece of chicken gets nice and saucy.
4. Cheese, Please
Sprinkle the mozzarella cheese over the top, followed by the Parmesan. At this point, your kitchen will already start smelling heavenly.

5. The Crunchy Topping
In a small bowl, mix the crushed garlic croutons with melted butter, garlic powder, and Italian seasoning. Stir until the crumbs are lightly coated, then scatter them generously over the cheese layer. The croutons add such a satisfying crunch—trust me, don’t skip this step!
6. Bake
Slide the casserole into the oven and bake uncovered for about 25–30 minutes. You’ll know it’s ready when the top is beautifully golden and the edges are bubbling.
7. Garnish and Serve
Sprinkle some fresh chopped parsley over the top for a pop of color and freshness. Scoop out big, steaming portions and watch everyone come running to the table.
HELPFUL TIPS:
-
Use rotisserie chicken for a shortcut that still feels homemade.
-
Crush the croutons finely for a more even topping, or leave them chunky if you like extra crunch.
-
Customize your casserole by adding sautéed mushrooms, spinach, or even cooked pasta underneath the chicken layer.
-
Make it ahead: Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking.
-
Freezer-friendly: You can freeze the assembled casserole (before baking) for a busy day rescue meal.
