Ingredients
- 2 lbs boneless, skinless chicken breasts, cut into bite-sized pieces
- 1 cup Italian breadcrumbs
- 1/2 cup grated Parmesan cheese
- 2 cups marinara sauce
- 2 cups shredded mozzarella cheese
- 1/4 cup olive oil
- 1 tsp garlic powder
- 1 tsp dried basil
- 1 tsp dried oregano
- Salt and pepper to taste
- Fresh basil for garnish
Step-by-Step Instructions
Step 1: Prepare the Chicken
Preheat your oven to 400°F (200°C). Cut the chicken breasts into uniform bite-sized pieces – this ensures everything cooks evenly and quickly.
Step 2: Create the Coating
In a medium bowl, combine the Italian breadcrumbs, grated Parmesan cheese, garlic powder, dried basil, oregano, salt, and pepper. This flavorful coating will give your chicken that signature parmesan crust without any frying.
Step 3: Coat and Arrange
Toss the chicken pieces in olive oil, then coat them thoroughly in the breadcrumb mixture. Arrange the coated chicken in a single layer in a 9×13 inch baking dish.
Step 4: Add Sauces and Cheese
Pour the marinara sauce evenly over the chicken, then top generously with shredded mozzarella cheese. The combination of crispy chicken underneath and melted cheese on top creates the perfect texture contrast.
Step 5: Bake to Perfection
Bake for 20-25 minutes, or until the chicken is cooked through and the cheese is golden and bubbly. For an extra crispy top, you can 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 extra Parmesan if desired. Serve hot with pasta, garlic bread, or a simple green salad.
Expert Tips for the Perfect Casserole
For Crispier Chicken: If you prefer extra crunch, you can lightly pan-sear the coated chicken pieces before baking. This adds texture while still keeping it a one-dish meal.
Make Ahead Magic: This casserole is perfect for meal prep. Assemble everything up to the baking step, cover, and refrigerate for up to 24 hours. When ready to serve, bake as directed, adding 5-10 minutes to account for the chilled ingredients.
Variation Ideas: Add sliced mushrooms, bell peppers, or spinach between the chicken and sauce layers for extra vegetables. This casserole works beautifully alongside other baked dishes like our Ultimate Instant Pot Chicken and Rice for larger gatherings.
Freezing Instructions: Bake the casserole completely, let it cool, then freeze in portions. Reheat in the oven at 350°F until warmed through. The texture holds up remarkably well to freezing.
