Step‑by‑Step Instructions for Dump-and-Bake Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). While the oven heats up, take a moment to grease a 13×9-inch baking dish with cooking spray or olive oil. This ensures that your delicious Dump-and-Bake Chicken Parmesan Casserole won’t stick and will come out perfectly golden.
Step 2: Combine Ingredients
In a large mixing bowl or directly in the greased baking dish, combine the uncooked penne pasta, marinara sauce, and water. Season with salt and ground black pepper, adding any additional herbs like garlic powder for extra flavor. Finally, stir in the diced raw chicken breast, making sure everything is evenly coated and well mixed.
Step 3: Bake Initially Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 30 minutes, which allows the chicken to cook through and the pasta to absorb all those wonderful flavors. You’ll know it’s time to check when the chicken is opaque and tender, and the pasta is semi-soft.
Step 4: Add Toppings
After 30 minutes, carefully remove the foil and stir the casserole gently, ensuring even distribution. The pasta should still be firm. Sprinkle the shredded mozzarella cheese, followed by panko breadcrumbs, and grated Parmesan cheese evenly over the top to create a delicious and crispy crust.
Step 5: Bake Uncovered
Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes. Watch closely as the cheese melts and turns golden brown while the casserole bubbles. This stage is where your Dump-and-Bake Chicken Parmesan Casserole becomes irresistibly inviting!
Step 6: Garnish and Serve
Once done, ensure the internal temperature of the chicken reaches 165°F (74°C). Take it out of the oven and allow it to cool slightly. Optionally, garnish with fresh chopped herbs for added color and flavor. Serve hot, and watch everyone enjoy the comforting flavors of this effortless casserole!
