Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

Cooked pasta (penne, rigatoni, or fettuccine)
Cooked chicken breast or rotisserie chicken (shredded or cubed)
Butter
Garlic (minced)
All-purpose flour
Heavy cream or half-and-half
Milk
Grated Parmesan cheese
Shredded mozzarella cheese
Salt and black pepper
Italian seasoning
Fresh parsley (optional, for garnish)

Directions

I preheat the oven to 375°F (190°C) and grease a large baking dish.
I cook the pasta just until al dente, then drain and set it aside.
In a large saucepan, I melt butter over medium heat and sauté garlic until fragrant.
I whisk in the flour and cook for 1–2 minutes to form a roux.
I slowly add in cream and milk, whisking constantly until smooth and thickened.
I stir in Parmesan cheese, Italian seasoning, salt, and pepper. Once melted and creamy, I remove it from the heat.
I mix the cooked pasta and chicken with the Alfredo sauce, then pour everything into the baking dish.
I top it with shredded mozzarella and bake uncovered for 20–25 minutes, until bubbly and lightly golden on top.
I let it cool for a few minutes before garnishing with parsley and serving.

Servings and timing

This dish makes about 6 servings. It takes 15 minutes to prep and 25 minutes to bake, so it’s ready in about 40 minutes from start to finish.

Variations

Sometimes I add steamed broccoli or spinach for a veggie boost. For extra flavor, I mix in crumbled bacon or sautéed mushrooms. I’ve also made this with shrimp instead of chicken for a seafood twist, or used gluten-free pasta and flour for a gluten-free version.

storage/reheating

I store leftovers in an airtight container in the fridge for up to 3 days. To reheat, I add a splash of milk and warm it in the microwave or oven until heated through. It also freezes well—I just wrap it tightly and bake from frozen (covered) at 350°F (175°C) for about 45–50 minutes. Creamy Chicken Alfredo Pasta Bake

FAQs

Can I use jarred Alfredo sauce?

Yes, if I’m short on time. I just mix it with the cooked pasta and chicken, then bake as directed. Homemade sauce gives the best flavor, but jarred works in a pinch.

What kind of pasta works best?

I usually use penne or rigatoni because they hold the sauce well, but fettuccine or rotini also work.

Can I make this ahead of time?

Definitely. I assemble the whole dish, cover, and refrigerate it overnight. I add a few extra minutes to the baking time when cooking it straight from the fridge.

Is this dish freezer-friendly?

Yes, I freeze it before or after baking. I wrap it tightly and bake directly from frozen or thaw overnight before reheating.

What can I serve with this?

I like to serve it with a simple green salad and garlic bread to soak up the creamy sauce.

Creamy Chicken Alfredo Pasta Bake is the ultimate comfort food that’s rich, hearty, and easy to love. It’s a satisfying crowd-pleaser that I turn to again and again, especially when I want a no-fuss dinner that feels a little special.
