Step‑by‑Step Instructions for Dump-and-Bake Chicken Parmesan Casserole
Step 1: Preheat the Oven
Begin your culinary journey by preheating your oven to 400 degrees Fahrenheit (200 degrees Celsius). This crucial step ensures that by the time you're ready to bake your Dump-and-Bake Chicken Parmesan Casserole, the oven will be perfectly hot, providing even cooking and allowing the cheese to melt perfectly.
Step 2: Combine Ingredients in Baking Dish
In a large baking dish, mix together 2 cups of uncooked penne pasta, 1 pound of bite-sized chicken breast pieces, 2 cups of marinara sauce, and 1 cup of water. Stir these ingredients until they are well combined, ensuring the penne is evenly coated in sauce. The dish will take on a vibrant, delicious appearance as you prepare for the next steps.
Step 3: Season the Mixture
Add 1 teaspoon of garlic powder, 1 teaspoon of Italian seasoning, 1 teaspoon of salt, and ½ teaspoon of black pepper to the baking dish. Gently fold these seasonings into the mixture to ensure an even distribution of flavors throughout your Dump-and-Bake Chicken Parmesan Casserole, creating a fragrant symphony that will fill your kitchen.
Step 4: Cover and Bake
Cover the baking dish tightly with aluminum foil, sealing in all the wonderful flavors. Place it in the preheated oven and bake for 25 minutes. Your kitchen will soon be filled with enticing aromas as the pasta cooks, and the chicken becomes tender and juicy.
Step 5: Stir and Check for Doneness
After 25 minutes, carefully remove the foil—watch out for steam! Give the pasta and chicken a gentle stir, checking that the pasta is tender and the chicken is fully cooked. This step ensures that each bite of your Chicken Parmesan Casserole is full of flavor and well blended.
Step 6: Add Cheese Toppings
Now comes the delicious part! Sprinkle 1 cup of shredded mozzarella cheese and ½ cup of grated Parmesan cheese evenly over the top of the casserole. This cheesy layer is what makes the Dump-and-Bake Chicken Parmesan Casserole truly irresistible, promising delectable melty goodness.
Step 7: Bake Uncovered for Golden Top
Return the dish to the oven uncovered and bake for an additional 10–15 minutes, or until the cheese is beautifully melted and bubbly. Keep an eye on it towards the end to achieve that golden, slightly browned top that will have everyone at your table eager to dig in.
Step 8: Let it Rest Before Serving
Once it’s done, remove the casserole from the oven, and allow it to sit for a few minutes to let the cheesy layers settle. If desired, garnish with fresh basil leaves for a pop of color and flavor. Serve this comforting Dump-and-Bake Chicken Parmesan Casserole warm, and enjoy the delight it brings to your dining experience!
