Dump & Bake Chicken Parmesan Casserole: Foolproof 7-Step Family Favorite

How to make Dump & Bake Chicken Parmesan Casserole

Ingredients:

2 cups cooked chicken, shredded or diced
2 cups uncooked penne or rotini pasta
3 cups marinara sauce
2½ cups water or chicken broth
1½ cups shredded mozzarella cheese, divided
½ cup grated Parmesan cheese
1 teaspoon garlic powder
1 teaspoon Italian seasoning
½ teaspoon salt
½ teaspoon black pepper
Optional chopped parsley for garnish

Directions:

Step 1: Prepare the Baking Dish
Preheat your oven to 375°F (190°C). Next, lightly grease a 9×13-inch baking dish. This helps to prevent sticking and makes for easy serving later.
Pro Tip: A light coating of oil also keeps the pasta edges from drying out while baking.

Step 2: Add Pasta and Chicken
Add the uncooked pasta and the cooked chicken directly to the baking dish. Spread them out evenly.
Pro Tip: Even distribution helps the pasta absorb liquid evenly and cook at the same pace.

Step 3: Add Sauce and Liquid
Pour the marinara sauce and water or chicken broth over the pasta and chicken. Make sure that most of the pasta is submerged.
Pro Tip: The liquid is what softens the pasta, so don’t reduce it or the pasta may stay firm.

Step 4: Season and Stir
Sprinkle in the garlic powder, Italian seasoning, salt, and black pepper. Stir everything together until well mixed.
Pro Tip: Stir gently so the pasta stays evenly coated without clumping.

Step 5: Cover and Bake
Cover the dish tightly with foil and bake for 35 minutes.
Pro Tip: The foil traps steam, which is essential for cooking the pasta without boiling it first.

Step 6: Add Cheese Layer
After 35 minutes, remove the foil and stir the casserole. Sprinkle 1 cup of mozzarella and all the Parmesan evenly over the top.
Pro Tip: Stirring before adding cheese prevents dry spots and helps the sauce thicken evenly.

Step 7: Finish Baking and Rest
Return the casserole to the oven uncovered and bake for 15–20 minutes until the cheese is melted and bubbly. Once done, let it rest for 5 minutes before serving.
Pro Tip: Resting allows the sauce to settle, making the casserole easier to slice and serve.

Tips and Mistakes to Avoid

Don’t Overcrowd the Dish: Make sure not to pack the chicken and pasta too closely together. This allows for even cooking and helps the pasta absorb all the flavors.
Use Enough Liquid: Ensure that your pasta is well-submerged in liquid. Without enough liquid, the pasta may end up hard and undercooked.
Rest Before Serving: Letting the casserole rest for a few minutes after baking helps to firm it up, making it easier to serve.
Choose Quality Ingredients: Opt for a good quality marinara sauce and shredded cheese. This enhances the overall flavor of the dish.
