Ingredients
- 2 lbs boneless, skinless chicken breasts, cubed
- 24 oz marinara sauce
- 2 cups shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1 cup Italian breadcrumbs
- 2 eggs, beaten
- 2 cloves garlic, minced
- 1 tsp Italian seasoning
- 1/2 tsp salt
- 1/4 tsp black pepper
- 2 tbsp olive oil
- Fresh basil for garnish
Step-by-Step Instructions
Step 1: Prep the Chicken
Cut chicken breasts into 1-inch cubes and season with salt, pepper, and Italian seasoning. Toss the chicken with beaten eggs until evenly coated.
Step 2: Create the Casserole Base
Spread 1 cup of marinara sauce evenly in the bottom of a 9×13 inch baking dish. This creates a flavorful foundation that prevents the chicken from sticking.
Step 3: Layer the Casserole
Add the egg-coated chicken cubes in a single layer over the sauce. Top with remaining marinara sauce, then sprinkle with breadcrumbs and Parmesan cheese. Finally, cover everything with shredded mozzarella.
Step 4: Bake to Perfection
Bake at 400°F for 20-25 minutes, until the cheese is golden and bubbly and the chicken is cooked through. For extra browning, broil for the last 2-3 minutes.
Expert Tips for Perfect Chicken Parmesan Casserole
- Make Ahead: Assemble the casserole up to a day in advance and refrigerate until ready to bake. Add 5-10 minutes to baking time if starting from cold.
- Cheese Variations: Mix in some provolone or fontina with the mozzarella for extra creaminess.
- Crispy Topping: For extra crunch, mix breadcrumbs with melted butter before sprinkling over the cheese layer.
- Chicken Alternatives: Use chicken thighs for richer flavor, or try this method with turkey cutlets.

Frequently Asked Questions
Can I use frozen chicken?
Yes, but thaw it completely first to ensure even cooking. Frozen chicken will release more liquid and may make the casserole watery.

How do I store leftovers?
Store covered in the refrigerator for up to 3 days. Reheat in the oven at 350°F until warmed through.
What side dishes pair well?
This casserole pairs perfectly with fresh pasta salad or garlic bread. For a complete Italian meal, try serving it alongside our delicious Tortellini Pesto Pasta Salad.
