Tender chicken, perfectly cooked pasta, a rich creamy sauce, and plenty of melted cheese bake together into a hearty meal that’s satisfying from the very first bite. It’s simple enough for a weeknight but delicious enough to serve when friends or family come over.
Chicken Pasta Casserole is a classic baked pasta dish made with cooked chicken, pasta, cheese, and a creamy sauce that’s baked until hot and bubbly. Every bite is filled with tender chicken, gooey cheese, and perfectly coated pasta, making it a meal everyone enjoys. It’s naturally high in protein, easy to customize with vegetables or different cheeses, and perfect for meal prep because it reheats beautifully throughout the week.

- ½ cup milk – Milk helps create a smooth sauce that evenly coats the pasta.
- 2 cups shredded cheddar cheese, divided – Cheddar cheese melts beautifully and creates a rich, cheesy topping.
- 1 cup shredded mozzarella cheese – Mozzarella adds a gooey, stretchy texture that makes every bite extra delicious.
- 1 small onion, diced – Onion adds sweetness and builds extra flavor as the casserole bakes.
- 2 garlic cloves, minced – Fresh garlic gives the casserole a rich, savory flavor.
- 1 teaspoon Italian seasoning – Italian seasoning adds a blend of herbs that pairs perfectly with the creamy sauce.
- ½ teaspoon paprika – Paprika adds a touch of smoky flavor and color.
- 1 teaspoon salt – Salt enhances the overall flavor. Adjust depending on the saltiness of your soup and cheese.

How to Store and Reheat
Refrigerator
Store leftover Chicken Pasta Casserole in an airtight container in the refrigerator for up to 4 days.
Freezer
Freeze the baked casserole in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat individual portions in the microwave until hot, or warm the casserole in a 350°F (175°C) oven for about 20 minutes. Add a splash of milk if needed to keep the sauce creamy.
Common Mistakes to Avoid
Overcooking the pasta
Cook the pasta only until al dente because it continues cooking in the oven. Overcooked pasta can become soft and mushy.
Using too little sauce
Pasta absorbs moisture while baking, so make sure it’s well coated with the creamy sauce before it goes into the oven.
Skipping the resting time
Allow the casserole to rest for 5 to 10 minutes before serving. This gives the sauce time to thicken and makes serving much easier.
Using only pre-shredded cheese
Freshly shredded cheese melts more smoothly and gives the casserole a creamier texture than pre-shredded cheese.
Adding too much salt
The canned soup and cheese already contain salt, so taste the sauce before adding additional seasoning.

Chicken Pasta Casserole
Ingredients
Method
- Preheat the oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
- Cook the pasta according to the package directions until just al dente. Drain and set aside.
- Melt the butter in a large skillet over medium heat. Add the garlic and cook for 30 seconds until fragrant.
- Stir in the flour and cook for 1 minute, stirring constantly.
- Gradually whisk in the chicken broth, then stir in the heavy cream. Simmer for 3 to 4 minutes until the sauce begins to thicken.
- Add the Italian seasoning, garlic powder, salt, black pepper, 1 cup mozzarella cheese, and the Parmesan cheese. Stir until the cheese has melted.
- Fold in the cooked chicken, cooked pasta, and frozen peas until everything is evenly coated.
- Transfer the mixture to the prepared baking dish and sprinkle with the remaining mozzarella cheese.
- Bake for 20 to 25 minutes, or until the cheese is melted and bubbly. Broil for 2 to 3 minutes for a golden top, if desired.
- Let the casserole rest for 5 minutes before serving. Garnish with fresh parsley.
Notes
- Cook the pasta just until al dente since it will continue cooking in the oven. Overcooked pasta can become soft after baking.
- Shred your own mozzarella and Parmesan for the smoothest, meltiest cheese sauce. Pre-shredded cheese doesn’t melt as well.
- Let the casserole rest for 5 to 10 minutes after baking so the sauce thickens slightly and the servings hold together better.
- This casserole is easy to customize with vegetables like broccoli, spinach, mushrooms, or diced bell peppers. Cook any vegetables with a high water content before adding them to prevent a watery casserole.
- Assemble the casserole up to one day in advance, cover, and refrigerate. When baking from cold, add 10 to 15 minutes to the baking time until it’s hot all the way through.
