Use your favorite homemade or quality store-bought marinara.
Cheese
- 2 cups shredded mozzarella cheese, divided
- ½ cup grated Parmesan cheese
Mozzarella creates the signature stretchy cheese layer, while Parmesan adds savory depth.

- Salt

Additional Ingredients
- 1 tablespoon olive oil
- Fresh chopped basil for garnish (optional)

How to Make Chicken Parmigiana Casserole
Step 1: Prepare the Baking Dish
Preheat the oven to 375°F (190°C).
Lightly grease a 9×13-inch baking dish with nonstick cooking spray.
This helps prevent sticking and makes serving easier.
Step 2: Season the Chicken
Pat the chicken breasts dry with paper towels.
Season both sides with:
- Salt
- Black pepper
- Italian seasoning
Even seasoning ensures flavorful chicken throughout the casserole.
Step 3: Sear the Chicken
Heat the olive oil in a large skillet over medium heat.
Sear the chicken for 3 to 4 minutes per side until lightly golden.
The chicken does not need to be fully cooked at this stage.
Transfer it to a cutting board and allow it to cool slightly.
Step 4: Slice the Chicken
Cut the partially cooked chicken into bite-sized pieces or thin strips.
Smaller pieces cook evenly and distribute well throughout the casserole.
Step 5: Combine the Filling
In a large mixing bowl, combine:
- Chicken pieces
- Marinara sauce
- 1 cup shredded mozzarella
- Minced garlic
Stir until everything is evenly coated.
Step 6: Assemble the Casserole
Transfer the chicken mixture into the prepared baking dish.
Spread it into an even layer.
Step 7: Prepare the Topping
In a separate bowl, combine:
- Breadcrumbs
- Remaining 1 cup mozzarella
- Parmesan cheese
Mix well.
Sprinkle the topping evenly across the casserole.
This creates the signature crispy, cheesy crust.
Step 8: Bake
Bake for 25 to 30 minutes.
The casserole is ready when:
- The cheese is melted
- The topping is golden brown
- The sauce is bubbling
- The chicken reaches an internal temperature of 165°F (74°C)
Step 9: Finish and Serve
For extra crispiness, broil for 2 to 3 minutes.
Watch carefully to avoid burning.
Allow the casserole to rest for 5 minutes before serving.
Garnish with chopped fresh basil if desired.
Tips for the Best Chicken Parmigiana Casserole
Sear Before Baking
Browning the chicken adds extra flavor and locks in moisture.
Use Freshly Shredded Cheese
Fresh mozzarella melts more smoothly than pre-shredded varieties.
Don’t Overcook the Chicken

Let It Rest
Resting the casserole helps it set for easier serving.
