Baked chicken spaghetti is a simple dinner casserole that can be made ahead of time and frozen for later as an easy meal. A creamy sauce over shredded chicken and creamy spaghetti noodles is comfort food at it’s finest.

What you’ll need

You will need a 13×9” casserole dish, large pot, and colander for this recipe.

  • Spaghetti– for the best noodle, use a lighter color
  • Chicken, shredded– rotisserie chicken leftovers are great for shredding and tossing with spaghetti
  • Velveeta Cheese– one 16 oz. block
  • Cream Cheese
  • Diced Tomatoes and Chilies (or Rotel)
  • Cream of Mushroom Soup– any brand will do!
  • Cream of Chicken Soup
  • Garlic Powder
  • Onion Powder
  • Creole Seasoning (optional)
  • Mozzarella Cheese, shredded
  • Cheddar Cheese, shredded

Making a huge batch of spaghetti for the whole family is the ultimate in comfort food.

To boost the flavor of this dish, I threw in some large chunks of pre-cooked, store-bought rotisserie chicken. Add some melted cheese on top for even more flavor!

When I’m in a rush, this meal is our family’s go-to Italian-inspired supper and it lasts for a few days.

How to make creamy baked chicken spaghetti

  1. Preheat the oven to 350 degrees Fahrenheit and shred the rotisserie chicken once it has been deboned. 
  2. In a large pot, cook the pasta until it is al dente (just soft enough to the bite). Drain the water and set it aside.
  3. Add the velveeta cheese, cream cheese, chopped tomatoes and chilies, cream of mushroom soup, and cream of chicken soup to the same pot where the spaghetti was cooked.
    Stir constantly over medium heat until everything has melted and blended.
    Stir in the garlic powder, onion powder, and Creole Seasoning.
  4. Combine the pasta and shredded chicken in a large mixing bowl. Toss well to ensure that everything is equally distributed.
  5. Pour the mixture into a 13×9″ casserole dish that has been gently oiled.
    Place in the oven after sprinkling the mozzarella and cheddar cheese over the top.
  6. Bake for 25-30 minutes, or until the edges are bubbling.

Serve the baked chicken spaghetti while it’s still hot, garnished with parsley.

Shredded mozzarella and cheddar cheese go into the pasta to create a cheesy crust. The cheddar imparts a great aged, sharp taste to these cheeses, which melt beautifully. I bake the casserole with the lid on at 350 degrees for about 35 minutes.

seconds, please!

By using this temperature, you’re able to cook the pasta without drying it out while also melting the cheese on top. Just before serving, broil the cheese for a few minutes if you want it golen-brown.

Add some red pepper flakes to the sauce if you love a spicy kick to compliment the creamy chicken bake.

Recipe FAQ

How do I make a vegan option?

Red bell pepper, spinach, or zucchini are good additions to the meal if you’d want to include some veggies or for a vegan option.

What kind of chicken can I use?

To make this meal, you can use any kind of cooked chicken. Cooked or roasted chicken breasts are excellent options.

The minimum amount of chicken needed is 2 cups; however, if you prefer more protein over noodles, simply reduce the spaghetti and add more chicken.
