casserole version of a classic

Who doesn’t love Pasta?! We make at least one pasta dish a week.

Our favorites include Spaghetti, Homemade Mac and Cheese, Creamy Penne Pasta – you name it!

We LOVE Fettuccine Alfredo and knew a casserole version with chicken would be just as good. We were right… this recipe is a family favorite and is on the monthly rotation because it’s loved by all.

Penne pasta for Chicken Alfredo casserole recipe.

How to Make

OPTIONAL MARINADE. If time allows, marinate the chicken. Add chicken and Italian dressing to a bag. Let sit overnight or even a few hours to make the chicken tender and full of flavor.

PASTA. Cook pasta as directed. Drain and set aside.

While pasta is cooking, heat 1-2 TB of oil in a skillet on medium heat.

CHICKEN. Slice your marinated chicken in half so they are thinner pieces. This will help them cook through evenly.

  • In a bowl, mix salt, pepper, thyme, and poultry seasoning. Rub it on all sides of your chicken breasts.
  • Add chicken to hot oil and cook on both sides until done (about 15-20 minutes).
  • Remove to a plate to let cool.

SAUCE. While the chicken is cooling, preheat your oven to 350°F and start on your sauce. In a separate large skillet melt the butter; add garlic and cook for 1-2 minutes.

  • Using a wire whisk, mix in flour and stir until bubbly.
  • Mix in half & half and milk (you can also sub these two for heavy cream), and stir to combine. Bring to a boil and then reduce to low heat and simmer for 5 minutes.
  • With your whisk, mix in 1½ cups of cheese. Cook an additional 5 minutes until the sauce starts to thicken.
  • Remove sauce from heat.

ASSEMBLE. Cut your cooked chicken into bite-size pieces and add to a large bowl. Add the pasta to your bowl and then the sauce. Mix everything to combine.

BAKE. Spray a 9×13 baking dish with nonstick spray. Add the pasta mixture to the pan and sprinkle with an additional 1½ cups of cheese.

Sprinkle with pepper and bake for 30 minutes or until bubbly and golden brown. Garnish the dish with chopped parsley, if desired.

Recipe Tips

Pasta. Alfredo sauce is often served over fettuccine noodles, but we chose to use penne noodles for this baked dish. Other pasta choices include mini penne or rigatoni.

Veggies. Add broccoli, spinach, peas, corn, bell peppers, or mushrooms.

Chicken. Use leftover chicken or rotisserie chicken to save time. Make chicken alfredo pasta bake without chicken or substitute the chicken with cooked sausage. Mix in shrimp or add crumbled bacon on top. 

Kraft 5 Italian Cheese Blend contains mozzarella cheese, provolone cheese, parmesan cheese, asiago cheese, and romano cheese. Shred your own cheese blend using these cheeses.

What to serve with Baked Chicken Alfredo

There are so many sides and bread that go great with this chicken alfredo casserole. Here are some of our favorites:

Storing Info

Make ahead of time. Prepare as directed, cover, and place in the fridge. We typically do this the night before or the morning of, but it can be stored up to 24 hours before baking.

STORE leftovers in an airtight container(s) in the fridge for 3-4 days.

FREEZE. Allow the ingredients to cool and then wrap the dish with plastic wrap and again with aluminum foil. If done properly, it will keep for up to 2-3 months in the freezer.

Reheat. The best way to reheat a large amount is in the oven or on the stovetop. Reheat slowly over low heat and add extra milk to help smooth out the texture.

If you are in a hurry, or on the go, reheat smaller portions in the microwave.

  7. Pam Kelly says:

    I only have 2 cups of half and half. Do I add an extra cup of milk?

    1. Lil'Luna Team says:

      Yes, you could do that and it should still turn out just fine!

  8. Barbara says:

    When do you add the olive oil. The recipe doesn’t say.

    1. Lil'Luna Team says:

      I think we may have double listed the oil…. you can use either olive or vegetable to pan fry the chicken. We’ll look into updating that recipe card. Thanks!
