An Easy Casserole

I love this dish because it’s the ultimate comfort food and the whole family will love it.

  • Filling and satisfying, this chicken spaghetti casserole is simple to make.
  • There are two options for the creamy cheesy sauce:
    • a homemade from-scratch sauce
    • OR a shortcut version for busy nights (both are listed below).
  • Just like a traditional baked spaghetti casserole, you likely have all of the ingredients on hand!
  • Prepping it is easy and even more so if you make it with rotisserie chicken or leftover chicken breasts!

Ingredients for Chicken Spaghetti

ChickenI usually make this chicken spaghetti recipe with rotisserie chicken since it’s easy; simply shred two cups. If using raw chicken breasts, either poach or bake and then shred it. You can also make a big batch of crock pot shredded chicken to keep in the freezer.

Spaghetti – Use any long pasta you have on hand. Cook it al dente (which means firm) as it will cook more in the oven as the spaghetti bakes.

Sauce – I love the from-scratch version of the sauce for this recipe, but if you’re in a rush, I’ve included a shortcut version too. Green or red peppers add flavor while cream and cheese help make a rich and flavorful sauce. Use a sharp cheddar for the best flavor.

How to Make Chicken Spaghetti

This is an easy chicken spaghetti recipe:

  1. Boil the spaghetti until al dente
  2. Prepare the cream sauce (per the recipe below) and cook until thick and bubbly. Remove from the heat and add in the cheese.
  3. Combine the pasta, chicken, and diced tomatoes in a greased casserole dish.
  4. Top with more cheese and bake until bubbly!
  5. Allow the baked chicken spaghetti to rest for five minutes to help the sauce thicken.

Short Cut Chicken Spaghetti Sauce

Short on time? Make a Short Cut Chicken Spaghetti Recipe! Try it with canned cream of mushroom soup, and a can or two of Rotel tomatoes instead – be sure to buy the Rotel without lime added!

Here’s a quick and easy shortcut sauce for chicken spaghetti:

  1. Sautee the bell pepper and onion in butter until tender.
  2. Stir in ¾ pound diced processed cheese (like Velveeta cheese) and one can of cream of mushroom soup (or cream of chicken soup). Heat until melted and creamy.
  3. Season with ½ teaspoon each of onion powder, garlic powder, and black pepper if you’d like. I skip the salt, as the cheese and condensed soup have enough for my liking.
  4. Continue as directed in the recipe by adding diced tomatoes and shredded or bite-size pieces of chicken.

What to Serve With Spaghetti Casserole

Baked chicken spaghetti is rich and filling so it doesn’t need much on the side. Serve up the same favorites you serve with lasagna like a fresh salad and some dinner rolls, biscuits, or garlic bread.

Leftovers & Meal Prep

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Chicken spaghetti freezes very well and can be frozen before baking for up to four months.

To bake from frozen, cover with aluminum foil to prevent the cheese topping from overcooking and bake at 375°F for about an hour, or until it is piping hot throughout! Be careful as most glass dishes cannot go from freezer to oven)

Freezer Tip

If preparing ahead of time and freezing, line your baking dish with parchment paper. Once frozen, lift the casserole from the baking dish, wrap it tightly with plastic wrap, and freeze. Then just pop the chicken spaghetti back into the casserole dish when you’re ready to bake it.
