Creamy Chicken and Pasta Casserole

This Chicken and Pasta Casserole is the kind of dinner that checks all the boxes on a busy evening: tender chicken, pasta, vegetables, plenty of creamy sauce, and melted cheese, all baked together in one comforting dish.

The sauce is made from scratch with butter, flour, milk, broth, and cheese, so you get a smooth, creamy texture without relying on canned soup. Broccoli adds color and freshness, while mozzarella and cheddar melt over the top and create those golden cheesy spots everyone reaches for first.

This creamy chicken pasta casserole is hearty enough to serve on its own, but it is still simple enough for an ordinary weeknight.

For a halal-friendly version, use halal-certified chicken and chicken broth, and check that your cheeses are made with suitable enzymes.

If you prefer chicken casseroles built around rice instead of pasta, my Chicken Wild Rice Casserole is another cozy family dinner.

Why You’ll Love This Chicken and Pasta Casserole

A good Chicken and Pasta Casserole should be creamy without becoming heavy or watery.

This version gets that balance from a simple homemade sauce.

The pasta carries the sauce into every bite, while the chicken makes the casserole filling enough for dinner. Broccoli adds a little texture and keeps the dish from feeling like pasta and cheese alone.

You will also appreciate that this chicken pasta casserole is:

• Family-friendly
• Easy to assemble ahead
• Made with simple ingredients
• Great for using cooked chicken
• Freezer-friendly
• Easy to customize

And because the entire dish finishes in the oven, the flavors of the pasta, chicken, sauce, and cheese come together instead of feeling like separate ingredients.

Ingredients You’ll Need

For about 6 to 8 servings:

• 12 ounces penne, rotini, or rigatoni
• 3 cups cooked halal-certified chicken, diced or shredded
• 3 cups small broccoli florets
• 3 tablespoons unsalted butter
• 3 garlic cloves, minced
• 3 tablespoons all-purpose flour
• 2 cups low-sodium halal-certified chicken broth
• 1½ cups whole milk
• ½ cup heavy cream
• 1 teaspoon Italian seasoning
• ½ teaspoon garlic powder
• ½ teaspoon salt, or to taste
• ¼ teaspoon black pepper
• 1½ cups shredded cheddar cheese, divided
• 1½ cups shredded mozzarella cheese, divided
• ¼ cup grated Parmesan, optional
• 2 tablespoons chopped parsley, optional

Short pasta shapes work best for this Chicken and Pasta Casserole because they hold onto the creamy sauce and distribute more evenly through the baking dish.

How to Make Chicken and Pasta Casserole

1. Preheat the Oven

Preheat the oven to 375°F.

Lightly grease a 9×13-inch baking dish.

Bring a large pot of salted water to a boil for the pasta.

2. Cook the Pasta

Add the pasta and cook it about 2 minutes less than the package directions.

The pasta should still have a firm center because it will continue cooking in the oven.

During the final 2 minutes of the pasta cooking time, add the broccoli florets directly to the pot.

This quickly softens the broccoli without making it mushy.

Drain the pasta and broccoli well.

Do not rinse them.

Slightly undercooked pasta is important for a good cheesy chicken pasta bake because fully cooked pasta can become too soft after baking.

3. Make the Creamy Sauce

Melt the butter in a large skillet or saucepan over medium heat.

Add the garlic and cook for about 30 seconds.

Sprinkle in the flour and whisk constantly for about 1 minute.

Slowly pour in the chicken broth while whisking.

Add the milk and heavy cream.

Continue cooking for about 4 to 6 minutes, stirring frequently, until the sauce begins to thicken.

Season with Italian seasoning, garlic powder, salt, and black pepper.

4. Add the Cheese

Reduce the heat to low.

Stir in:

• 1 cup cheddar
• 1 cup mozzarella
• Parmesan, if using

Stir until the cheese has melted and the sauce is smooth.

The sauce for your creamy chicken pasta casserole should be thick enough to coat the pasta but still pour easily.

If it becomes extremely thick, stir in a small splash of milk.

5. Combine the Chicken, Pasta, and Broccoli

Place the drained pasta and broccoli in a large mixing bowl.

Add the cooked chicken.

Pour the cheese sauce over everything.

Gently fold until the chicken, broccoli, and pasta are evenly coated.

Taste and adjust the seasoning before transferring the mixture to the baking dish.

This is also the point where you can judge the consistency. Your Chicken and Pasta Casserole should look very creamy before baking because the pasta will absorb some sauce in the oven.

6. Assemble the Casserole

Transfer the chicken pasta mixture to the prepared 9×13-inch baking dish.

Spread it evenly.

Sprinkle the remaining:

• ½ cup cheddar
• ½ cup mozzarella

over the top.

This final cheese layer creates the golden, bubbly finish that makes a chicken casserole with pasta especially comforting.

7. Bake Until Bubbling

Bake uncovered for approximately 20 to 25 minutes.

The sauce should be bubbling around the edges and the cheese should be fully melted.

If you want more golden color, broil the casserole for 1 to 2 minutes at the end.

Watch it carefully.

The USDA recommends that poultry and casseroles containing previously cooked poultry reach 165°F when reheated or cooked through. USDA Safe Minimum Internal Temperature Chart

Let the Chicken and Pasta Casserole rest for 5 to 10 minutes before serving.

What Pasta Works Best?

Penne, rotini, and rigatoni are my favorite choices for Chicken and Pasta Casserole.

Their shapes catch plenty of creamy sauce and stand up well during baking.

Rotini holds sauce inside its spirals.

Penne gives the casserole a slightly cleaner appearance when served.

Rigatoni works especially well if you prefer larger pieces of pasta.

You can use elbow macaroni, but it tends to create a softer chicken pasta casserole.

I would avoid very delicate pasta shapes because they can become too soft after cooking twice.

Why You Should Undercook the Pasta

Pasta continues absorbing liquid in the oven.

If you cook it completely before assembling the Chicken and Pasta Casserole, it may become overly soft by the time the cheese is melted and the sauce is bubbling.

Cooking the pasta about 2 minutes short of al dente solves that problem.

It finishes cooking inside the creamy sauce instead.

This also helps the pasta absorb some of the flavor from the broth, chicken, and cheese.

It is a small step, but it makes a noticeable difference in the finished baked chicken pasta.

Can I Use Rotisserie-Style Chicken?

Yes.

Precooked chicken makes this Chicken and Pasta Casserole especially convenient.

You need about 3 cups of diced or shredded cooked chicken.

If you follow a halal diet, make sure the chicken is halal-certified.

Leftover baked or roasted chicken is also excellent.

You can use chicken breast or chicken thighs. Thigh meat tends to stay especially tender after the casserole is reheated in the oven.

Easy Variations

This chicken broccoli pasta casserole is easy to customize.

For extra vegetables, add mushrooms, peas, spinach, or diced bell peppers.

If using mushrooms, cook them first so they release their moisture before being added to the casserole.

For extra cheese flavor, replace part of the mozzarella with Monterey Jack.

For a little heat, add crushed red pepper flakes to the sauce.

You can also leave the broccoli out entirely and make a simpler creamy chicken pasta casserole with chicken, pasta, and cheese.

Or replace broccoli with frozen peas for an easy pantry-friendly version.

How to Keep Chicken Pasta Casserole From Drying Out

The most important step is starting with enough sauce.

The mixture should look a little creamier than you think it needs to be before it enters the oven.

Pasta absorbs moisture while baking.

Do not overcook the pasta beforehand, and do not leave the Chicken and Pasta Casserole in the oven much longer than necessary.

You are mainly baking it to heat everything through and melt the cheese.

The chicken is already cooked and the pasta is almost done.

Overbaking simply removes moisture.

What to Serve With Chicken and Pasta Casserole

This casserole already contains chicken, pasta, broccoli, and cheese, so it works perfectly well as a complete dinner.

A simple green salad makes a good fresh side.

Roasted asparagus or green beans also work well if you want additional vegetables.

Garlic bread is a natural choice for a larger family meal, although the pasta already makes this Chicken and Pasta Casserole quite filling.

For busy weeknights, I usually keep the sides simple.

Can You Make Chicken and Pasta Casserole Ahead?

Yes.

Prepare the pasta, broccoli, chicken, and sauce as directed.

Assemble the Chicken and Pasta Casserole in the baking dish and allow it to cool.

Cover and refrigerate.

For the best texture, bake it within about 24 hours.

When baking directly from the refrigerator, add approximately 10 minutes to the cooking time.

If the pasta mixture seems slightly dry before baking, drizzle a few tablespoons of milk over it before adding the final cheese layer.

How to Store Leftovers

Allow leftover Chicken and Pasta Casserole to cool before transferring it to airtight containers.

Refrigerate promptly.

Individual portions reheat well in the microwave.

Because pasta continues absorbing sauce as it sits, I like to add a tablespoon or two of milk before reheating.

This brings some creaminess back to the sauce.

For larger portions, cover the casserole with foil and reheat it gently in the oven.

Can You Freeze Chicken and Pasta Casserole?

Yes.

This Chicken and Pasta Casserole freezes reasonably well.

For the best results, slightly undercook the pasta and cool the casserole completely before freezing.

You can freeze the entire casserole or divide it into individual portions.

Thaw overnight in the refrigerator before reheating.

Creamy dairy-based sauces can change texture slightly after freezing, but gentle reheating helps bring the sauce back together.

Chicken and Pasta Casserole FAQ

Can I Use Raw Chicken?

I recommend using cooked chicken.

The cooking time for this casserole is designed to heat the ingredients and melt the cheese, not to cook raw chicken safely from beginning to end.

Can I Use Frozen Broccoli?

Yes.

Thaw the broccoli first and drain it thoroughly.

Too much water from frozen broccoli can thin the sauce.

Can I Leave Out the Heavy Cream?

Yes.

Replace it with additional whole milk.

The Chicken and Pasta Casserole will be slightly lighter but still creamy.

Can I Use Cream Cheese?

Yes.

Add about 4 ounces of softened cream cheese to the sauce for an even richer creamy chicken pasta casserole.

Reduce some of the shredded cheese if you do not want the casserole to become too heavy.

Why Is My Pasta Casserole Dry?

The pasta may have been cooked too long before baking, there may not have been enough sauce, or the casserole may have stayed in the oven too long.

Can I Prepare This the Night Before?

Yes.

Assemble it, cover it tightly, refrigerate overnight, and bake the following day.

Allow a little extra cooking time when starting with a cold casserole.
