Ingredients Method Notes

Ingredients
  

Ingredients
  • 2 lbs boneless, skinless chicken breasts, cubed
  • 3 cups marinara sauce
  • 2 cups shredded mozzarella cheese
  • 1 cup grated parmesan cheese
  • 1 teaspoon Italian seasoning
  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon red pepper flakes (optional)
  • 2 tablespoons olive oil
  • Fresh basil for garnish
  • Salt and pepper to taste

Method
 

Instructions
  1. Preheat your oven to 400°F (200°C) and grease a 9x13 inch baking dish with olive oil or cooking spray.
  2. Cut the chicken breasts into 1-inch cubes and season with Italian seasoning, garlic powder, onion powder, salt, and pepper. Toss to coat evenly.
  3. Spread the seasoned chicken cubes in an even layer in the prepared baking dish. Drizzle with olive oil and bake for 15 minutes until the chicken is cooked through.
  4. Remove the dish from oven and pour the marinara sauce evenly over the chicken. Stir gently to combine.
  5. Sprinkle the shredded mozzarella and parmesan cheese over the top, covering the entire surface.
  6. Return to oven and bake for another 10-15 minutes until the cheese is melted, bubbly, and lightly golden.
  7. Garnish with fresh basil leaves and let rest for 5 minutes before serving.

Notes

Use high-quality marinara sauce for best flavor. The casserole can be assembled ahead and refrigerated before baking. Let rest for 5 minutes after baking to allow flavors to meld together.
