Ingredients

For the base:

12 ounces (340 g) pasta (penne or rigatoni work well)
2 cups cooked chicken, shredded or diced (rotisserie chicken saves time)
Salt and black pepper, to taste

For the creamy pesto sauce:

1 cup jarred or homemade pesto (about 8 ounces)
1 1/2 cups heavy cream or half-and-half (use heavy cream for richer sauce)
1/2 cup chicken broth (low-sodium if preferred)
1 cup shredded mozzarella cheese (divided)
1/2 cup grated Parmesan cheese
1 small onion, finely chopped (about 1/2 cup)
2 cloves garlic, minced

For finishing:

2 tablespoons olive oil or butter (for sautéing)
1/2 cup breadcrumbs or panko (optional, for a crunchy top)
Fresh basil leaves or extra Parmesan for garnish

Notes: If your butter or cheese is salted, taste before adding extra salt.

How to Make Creamy Pesto Chicken Pasta Bake

Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish. (Preheating ensures even baking.)
Cook the pasta in salted boiling water for 2 minutes less than package directions; drain and set aside. (Under-cooking keeps the pasta from getting mushy in the oven.)
Heat olive oil or butter in a skillet over medium heat. Add the chopped onion and cook until soft and translucent, about 4–5 minutes. Add garlic and cook 30 seconds more until fragrant.
Stir in the pesto, heavy cream, and chicken broth. Bring the sauce to a gentle simmer and let it thicken for 2–3 minutes. (This helps the flavors meld and the sauce coat the pasta.)
Add 1/2 cup of mozzarella and the grated Parmesan to the sauce. Stir until melted and smooth. Season with salt and pepper to taste.
Toss the cooked pasta and shredded chicken into the sauce, making sure everything is evenly coated. Pour into the prepared baking dish and spread level.
Sprinkle the remaining 1/2 cup mozzarella and the breadcrumbs evenly over the top for a golden finish. (For a softer top, skip the breadcrumbs and add more cheese.)
Bake for 18–22 minutes, until bubbly and the top is golden. If you like a crispier top, broil for 1–2 minutes while watching closely.
Let the bake rest 5 minutes before serving so the sauce sets slightly. Garnish with fresh basil or extra Parmesan. (Resting helps the bake firm up and makes it easier to serve.)

How to Serve Creamy Pesto Chicken Pasta Bake

Spoon onto warm plates and top with torn fresh basil and a sprinkle of Parmesan for a bright finish.
Serve with a simple green salad or roasted veggies and warm crusty bread to soak up the sauce. You can also pair it with our lighter side dish, Creamy Hot Honey Chicken Orzo Bake, for a themed meal night.
For a family-style platter, place the baking dish in the center of the table and let everyone help themselves.

How to Store Creamy Pesto Chicken Pasta Bake

Fridge: Cool to room temperature, cover tightly, and store in an airtight container for up to 3–4 days.
Freezer: Freeze in a freezer-safe dish for up to 2 months. Thaw in the fridge overnight before reheating.
Reheat: Warm individual portions in the microwave for 2–3 minutes, stirring halfway. For the whole dish, reheat covered at 350°F (175°C) for 20–25 minutes until warmed through.

Tips to Make Creamy Pesto Chicken Pasta Bake

Use rotisserie chicken to save time and add flavor.
Slightly undercook the pasta so it won’t over-soften in the oven.
Taste the sauce before baking and adjust salt or pesto for more herb flavor.
For a lighter bake, swap half the cream for milk and add a tablespoon of flour to thicken.
Watch the broiler closely—breadcrumbs can brown fast.

Variation

Gluten-free: Use gluten-free pasta and gluten-free breadcrumbs.
Vegetarian: Replace chicken with roasted mushrooms or chickpeas for a hearty, meat-free bake.

Can I use store-bought pesto?

Yes. Good store-bought pesto works well and saves time. Taste it first; if it’s very salty, reduce added salt in the sauce.

Can I make this ahead of time?

Absolutely. Assemble the dish, cover, and refrigerate for up to 24 hours before baking. Add a few extra minutes to bake time if baking straight from the fridge.

How do I prevent a watery bake?

Avoid overcooking the pasta and make sure the sauce reduces slightly on the stove. If the sauce seems thin, simmer an extra minute to thicken before mixing with pasta.
