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 it warms up, take a moment to grease a 13×9 inch baking dish with nonstick spray, ensuring that the edges are well-coated to prevent sticking. This initial step sets the stage for a perfect bake, giving you a deliciously golden base for your Dump-and-Bake Chicken Parmesan Casserole.
Step 2: Mix Ingredients
In your greased baking dish, add the uncooked penne pasta, marinara sauce, and the specified amount of water. Sprinkle in salt and ground black pepper according to your taste. Next, incorporate the diced chicken breast into the mixture; this will create a hearty base. For an extra burst of flavor, consider mixing in a teaspoon of garlic powder or Italian seasoning during this step for a delightful aroma.
Step 3: Bake Covered
Cover your baking dish tightly with aluminum foil, making sure it seals well to trap the steam inside. Place the covered dish in the preheated oven and bake for 30 minutes. During this time, the pasta will absorb the marinara and water, creating a luscious foundation where all the flavors meld together.
Step 4: Add Toppings
Once the initial baking is complete, carefully remove the dish from the oven and take off the foil. Gently stir the mixture to combine everything thoroughly. Now it’s time to elevate your casserole: sprinkle the shredded mozzarella cheese evenly across the top, followed by a generous layer of panko breadcrumbs and the grated Parmesan cheese. This topping ensures a crispy finish to your Dump-and-Bake Chicken Parmesan Casserole.
Step 5: Final Bake
Return the uncovered casserole to the oven and bake for an additional 10-15 minutes. Watch closely as it cooks; you’re looking for the cheese to melt and bubble, forming a beautiful golden crust. When the chicken is fully cooked and the cheese is perfectly melted, it’s time for the delicious reveal of your comforting casserole.
Step 6: Serve
Once your casserole is done baking, carefully take it out of the oven and let it cool for a few moments. If you like, garnish with fresh herbs such as basil or parsley for an inviting touch and added flavor. Scoop out generous portions, and get ready to enjoy this heartwarming Dump-and-Bake Chicken Parmesan Casserole with your family!

Dump-and-Bake Chicken Parmesan Casserole Recipe FAQs
How do I select the best chicken for this casserole?
Absolutely! For the best flavor and texture, choose boneless, skinless chicken breasts. Look for pieces that are plump and pale in color without any dark spots. Fresh chicken should feel slightly moist but not slimy. If short on time, pre-cooked rotisserie chicken works wonders—just cut it into bite-sized pieces to mix into the casserole.
What’s the best way to store leftovers from the Dump-and-Bake Chicken Parmesan Casserole?
After enjoying a hearty meal, let your casserole cool down completely before transferring any leftovers to an airtight container. It will stay fresh in the refrigerator for up to 3 days. To ensure the best flavor, I recommend reheating it in the oven at 350°F (175°C) for 20-25 minutes, helping to restore its beautiful, crispy topping!
Can I freeze the Dump-and-Bake Chicken Parmesan Casserole?
Absolutely! You can freeze this delightful casserole for up to 2 months. To do so, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight and reheat it in the oven as directed. That way, the flavors stay intact, and the topping remains crispy.
What if my pasta is mushy after baking?
Oh no! To prevent mushy pasta, don’t overcook it. Make sure you’re using uncooked pasta in the casserole, which absorbs moisture during baking. Additionally, if you have leftovers, be careful not to overheat them during reheating; doing so can also lead to softer pasta. If you find yourself with mushy pasta, consider adding a sprinkle of fresh herbs or a squeeze of lemon to brighten the dish when serving.
Is this casserole pet-friendly?
While the ingredients in the Dump-and-Bake Chicken Parmesan Casserole—like chicken and cheese—might be tempting for your furry friends, it’s best not to share. Pets may have trouble digesting seasonings and cheese. If you want to treat them, consider cooking plain chicken without spices or sauces instead!
What can I do if I run out of mozzarella cheese?
No worries! If you’re short on mozzarella, feel free to substitute it with any cheese that melts beautifully, like provolone or even cheddar. This will give your casserole a unique spin while still ensuring that gooey, cheesy experience we all love.
