Why Everyone Loves This Baked Creamy Chicken Mozzarella Pasta

This pasta bake has everything you want in a comforting family dinner.

It’s creamy and cheesy. Heavy cream, Parmesan, and mozzarella create a rich combination that makes every bite satisfying.

The marinara adds brightness. Tomato-based marinara keeps the creamy sauce from feeling too heavy and gives the dish a familiar Italian-inspired flavor.

It’s packed with chicken. Two large cooked chicken breasts make the pasta bake hearty enough to serve as a complete meal.

The pasta holds the sauce beautifully. Penne captures the creamy sauce inside and around the pasta for flavorful bites throughout.

It’s easy to assemble. The sauce comes together in one skillet before being combined with the pasta and baked.

It’s perfect for sharing. A 9×13-inch baking dish makes this an excellent family-style dinner.

Ingredients Overview

Penne pasta: Penne is ideal because its hollow centers and ridges hold onto the creamy sauce. Other pasta shapes can also be used.

Cooked chicken breasts: Cubed cooked chicken makes this recipe convenient. Leftover roasted or grilled chicken can work well.

Olive oil: Used to sauté the onion and garlic, creating the flavorful foundation of the sauce.

Onion: Chopped onion adds sweetness and savory depth.

Garlic: Fresh minced garlic gives the sauce a fragrant flavor.

Heavy cream: Heavy cream creates the rich, smooth base of the creamy tomato sauce.

Marinara sauce: Marinara provides tomato flavor, acidity, and seasoning that balance the cream.

Mozzarella cheese: Mozzarella melts beautifully and creates the gooey topping that makes this pasta bake so appealing.

Parmesan cheese: Parmesan adds a salty, nutty flavor to the creamy pasta mixture.

Dried basil and oregano: These herbs provide classic Italian-inspired flavor.

Salt and black pepper: Season according to taste.

Fresh basil or parsley: An optional garnish that adds freshness and color.

Variations

This pasta bake is easy to customize based on what you have available.

Use another pasta shape: Rotini, rigatoni, ziti, shells, or bowtie pasta can replace penne.

Add vegetables: Spinach, broccoli, mushrooms, zucchini, or bell peppers can be added to the sauce.

Use different chicken: Leftover rotisserie chicken or cooked chicken thighs can be substituted for the chicken breasts.

Add more cheese: A little provolone, fontina, or Italian cheese blend can be combined with the mozzarella.

Make it spicy: Add crushed red pepper flakes to the sauce for a little heat.

Add sun-dried tomatoes: Chopped sun-dried tomatoes can provide an extra savory, slightly tangy flavor.

These are optional variations and are not part of the original recipe.

How to Make Baked Creamy Chicken Mozzarella Pasta

1. Prepare the baking dish

Preheat the oven to 375°F (190°C).

Lightly grease a 9×13-inch baking dish and set it aside.

2. Cook the pasta

Bring a large pot of salted water to a boil.

Cook the penne according to the package directions until it reaches an al dente texture.

Avoid overcooking the pasta because it will continue cooking slightly in the oven.

Drain the pasta well and set it aside.

3. Sauté the onion

Heat the olive oil in a large skillet over medium heat.

Add the chopped onion and sauté for approximately 3–4 minutes, or until it becomes soft and translucent.

Cooking the onion first helps develop a sweeter, more rounded flavor in the sauce.

4. Add the garlic

Add the minced garlic to the skillet.

Cook for approximately 30 seconds, stirring constantly, until fragrant.

Be careful not to let the garlic brown too much, as it can become bitter.

5. Make the creamy marinara sauce

Pour the heavy cream and marinara sauce into the skillet.

Stir well to combine.

Allow the sauce to simmer gently for approximately 2–3 minutes.

Add the dried basil, dried oregano, salt, and black pepper.

Stir until the herbs and seasonings are evenly distributed throughout the sauce.

6. Add the chicken

Add the cooked, cubed chicken to the sauce.

Stir gently until every piece of chicken is coated.

Allow the chicken to warm through in the sauce, then remove the skillet from the heat.

7. Combine the pasta and cheese

Add the cooked pasta to the skillet.

Gently toss until the pasta is evenly coated with the creamy chicken sauce.

Stir in 1 cup of the shredded mozzarella and all of the grated Parmesan cheese.

Mix until the cheeses are distributed throughout the pasta.

8. Assemble the pasta bake

Transfer the creamy chicken pasta mixture to the prepared baking dish.

Spread it into an even layer.

Sprinkle the remaining ½ cup mozzarella cheese evenly over the top.

9. Bake

Place the casserole in the preheated oven.

Bake uncovered for approximately 15–20 minutes, or until the cheese is completely melted and bubbling.

For a slightly more golden top, you can briefly broil the casserole at the end while watching it closely.

10. Garnish and serve

Remove the pasta bake from the oven and let it rest briefly.

Sprinkle chopped fresh basil or parsley over the top.

Serve warm while the mozzarella is still soft and melty.

Pro Tips and Cooking Secrets

Cook the pasta al dente. Slightly firm pasta holds up better during baking and won’t become mushy.

Don’t boil the cream sauce aggressively. A gentle simmer is enough to combine the cream and marinara while keeping the sauce smooth.

Use cooked chicken that’s still moist. Leftover chicken works well, but avoid very dry chicken because it can become even drier during baking.

Freshly shred the mozzarella. Freshly shredded cheese often melts more smoothly than pre-shredded varieties.

Don’t add all the mozzarella on top. Mixing some cheese into the pasta gives the interior a creamy, cheesy texture while the remaining cheese creates the golden topping.

Don’t overbake. The chicken and pasta are already cooked, so the oven’s main job is to heat everything through and melt the cheese.

Let the casserole rest briefly. A few minutes allows the sauce to settle and makes serving easier.

Add fresh herbs at the end. Basil or parsley adds freshness that balances the rich creamy sauce.

Serving Suggestions

This pasta bake is substantial enough to be the centerpiece of dinner, so simple side dishes work best.

A crisp green salad with lettuce, cucumber, tomatoes, and a light dressing provides freshness against the creamy pasta.

Garlic bread or warm crusty bread is another excellent choice. The bread is perfect for scooping up extra creamy marinara sauce.

For a vegetable side, try roasted broccoli, green beans, asparagus, or zucchini.

If you’re serving the dish for a family gathering, place the casserole directly on the table and garnish it with fresh basil or parsley just before serving.

A light tomato and cucumber salad can also add a refreshing contrast to the warm, cheesy pasta.

How to Store Baked Creamy Chicken Mozzarella Pasta

Allow leftovers to cool before transferring them to an airtight container.

Store in the refrigerator for up to 3–4 days.

Individual portions can be reheated in the microwave in short intervals until hot throughout.

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

If the pasta has absorbed some of the sauce during refrigeration, add a small splash of milk or cream before reheating to help restore its creamy texture.

The casserole can also be frozen in a freezer-safe container. Allow it to cool completely, cover tightly, and freeze.

Thaw overnight in the refrigerator before reheating.

FAQs

Can I use rotisserie chicken?

Yes. Rotisserie chicken is a convenient substitute for the cooked chicken breasts. Remove the skin and bones, then cube or shred the meat.

Can I use another type of pasta?

Absolutely. Rigatoni, rotini, ziti, shells, and bowtie pasta can all work well.

Can I make this pasta bake ahead of time?

Yes. Assemble the casserole, cover it tightly, and refrigerate until ready to bake. Because it will be cold from the refrigerator, it may require additional baking time.

Can I use half-and-half instead of heavy cream?

You can, although the sauce may be somewhat lighter and less rich. Heavy cream provides the creamiest result.

Why is my pasta mushy?

The pasta may have been cooked too long before baking. Cook it just until al dente because it will continue cooking in the oven.

Can I add vegetables?

Yes. Broccoli, spinach, mushrooms, zucchini, and bell peppers are all good optional additions.

What cheese can I use besides mozzarella?

Provolone, fontina, Monterey Jack, or an Italian cheese blend can be used as optional alternatives or combined with mozzarella.

Can I make it spicy?

Yes. Add crushed red pepper flakes or a little cayenne pepper to the sauce for extra heat.
