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) and lightly grease a 13×9-inch baking dish with cooking spray or olive oil. This sets the perfect foundation for your Dump-and-Bake Chicken Parmesan Casserole. Make sure the dish is well-greased to prevent sticking, which allows for easy serving later on.
Step 2: Combine Ingredients
In a large mixing bowl or directly in your greased baking dish, combine uncooked penne pasta, marinara sauce, and water, stirring well to ensure the pasta is evenly coated. Add a sprinkle of salt and ground black pepper to enhance the flavor, along with diced raw chicken breast. Optionally, boost the taste profile by adding garlic powder or Italian seasoning for that extra touch of warmth.
Step 3: Bake the Casserole
Once all the ingredients are combined, spread them evenly in the prepared baking dish. Cover it tightly with aluminum foil to trap steam, and bake in the preheated oven for 30 minutes. This method allows the pasta to absorb the delicious flavors while ensuring the chicken is cooked through and tender.
Step 4: Add Toppings
After the initial baking time, carefully remove the foil, taking care to avoid steam burns. Give the casserole a gentle stir to mix the layers, then sprinkle your generous amounts of shredded mozzarella cheese, panko breadcrumbs, and grated Parmesan cheese on top. This will create a delightful, cheesy crust as it bakes.
Step 5: Final Bake for Crispness
Return the casserole to the oven without covering it. Bake for another 10-15 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Keep an eye on it toward the end to achieve that perfect crispy texture without burning, making your Dump-and-Bake Chicken Parmesan Casserole irresistibly inviting.
Step 6: Garnish and Serve
Once done, remove the casserole from the oven and allow it to cool for a couple of minutes. If desired, sprinkle freshly chopped herbs over the top to add a pop of color and fresh flavor. Serve this comforting dish hot and enjoy the warm, gooey delight with your loved ones at the dinner table.

Dump-and-Bake Chicken Parmesan Casserole Recipe FAQs
What type of pasta should I use for this casserole?
Absolutely! Uncooked penne pasta is the star of this dish as it best absorbs the flavors of the sauce and chicken. If you don’t have penne on hand, you can easily substitute it with other short pastas like rotini or fusilli, just make sure they are uncooked.
How should I store leftovers of the casserole?
Very easy! You can store leftovers in an airtight container in the refrigerator for up to 3-4 days. Let the casserole cool completely before sealing it to prevent condensation, which can make it soggy. When you’re ready to eat, just reheat it in the oven or microwave—it’s still delicious!
Can I freeze Dump-and-Bake Chicken Parmesan Casserole?
Yes, you can freeze this casserole for up to 2-3 months. First, allow it to cool completely, then wrap it tightly in plastic wrap followed by aluminum foil. This double-wrapping method will protect it from freezer burn. When you’re ready to enjoy it, thaw it in the fridge overnight before reheating.
What should I do if my pasta is too soggy?
If you find that your casserole has turned out soggy, it may be due to excess water in your baking dish. Make sure to use the recommended amount of water and cover the dish with foil during the first baking phase, as this traps steam but does not over-saturate the pasta. In the future, feel free to add a little less water if you notice excess liquid.
Are there any dietary considerations for this casserole?
Yes! If you’re making this for someone with allergies, consider omitting the cheese to make it dairy-free, or use a dairy-free cheese alternative. For those watching their carbs, you can experiment with whole grain or gluten-free pasta. Always check labels and consult with guests if you’re unsure about specific dietary needs!
