Ingredients
- 1.5 lbs boneless, skinless chicken breasts, cut into 1-inch cubes
- 1 (24 oz) jar high-quality marinara sauce
- 2 cups shredded mozzarella cheese, divided
- 1/2 cup grated parmesan cheese
- 1 cup panko breadcrumbs
- 2 tablespoons olive oil
- 1 teaspoon Italian seasoning
- 1/2 teaspoon garlic powder
- 1/4 teaspoon red pepper flakes (optional)
- Salt and black pepper to taste
- Fresh basil leaves for garnish
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Preheat your oven to 400°F (200°C). Cut the chicken breasts into uniform 1-inch cubes and season with salt and pepper. This ensures even cooking throughout the casserole.
Step 2: Layer the Casserole
Spread 1/2 cup of marinara sauce in the bottom of a 9×13 inch baking dish. Arrange the seasoned chicken cubes evenly over the sauce. Pour the remaining marinara sauce over the chicken, ensuring all pieces are well coated.
Step 3: Add the Cheese
Sprinkle 1.5 cups of shredded mozzarella cheese evenly over the chicken and sauce mixture. Reserve the remaining 1/2 cup for the topping.
Step 4: Create the Crunchy Topping
In a small bowl, mix panko breadcrumbs with the remaining 1/2 cup mozzarella, parmesan cheese, Italian seasoning, garlic powder, and olive oil. Sprinkle this mixture evenly over the casserole.
Step 5: Bake to Perfection
Bake for 20-25 minutes, or until the chicken is cooked through (165°F internal temperature) and the topping is golden brown and crispy. If you like extra browning, broil for the last 2-3 minutes.
Step 6: Serve and Enjoy
Let the casserole rest for 5 minutes before serving. Garnish with fresh basil leaves and additional parmesan if desired.
Expert Tips for the Perfect Casserole
Make-Ahead Magic: Assemble the casserole up to 24 hours in advance and refrigerate. Add 5-10 minutes to baking time when cooking from cold.
Chicken Quality Matters: Use high-quality chicken breasts for the best texture. You can also substitute with chicken thighs for richer flavor.
Sauce Selection: Choose a marinara sauce you love – the flavor will shine through. Consider adding a teaspoon of sugar if your sauce is particularly acidic.
Breadcrumb Variation: For extra flavor, toast the panko breadcrumbs in a dry skillet before mixing with cheese and seasonings.
Resting Time: Don’t skip the resting period! This allows the sauce to thicken slightly and makes serving easier.
