In this easy chicken spaghetti recipe, shredded cooked chicken and spaghetti are smothered in a creamy, cheesy sauce and baked until browned and bubbly.

While the sauce is homemade, I’ve also included a shortcut sauce for busy weeknights!

It’s versatile; use any cheese or pasta.
This recipe is freezer-friendly – prep it ahead for busy days!

Ingredients for Chicken Spaghetti

Pasta: I use spaghetti noodles, but you can use other varieties of long pasta. Be sure to cook it al dente (firm) so it doesn’t overcook as the casserole bakes.

Chicken: This recipe uses cooked chicken. Shred rotisserie chicken or use up leftovers if you have them. If needed, baked chicken breasts work well too.

Flavor: Onion, garlic, and bell pepper add flavor, while canned diced tomatoes (or Rotel tomatoes) add a bit of freshness.

Chicken Broth: This is the base of the sauce and adds flavor—if using low-sodium broth or stock, add some extra salt.

Cream: Half and half or light cream makes the sauce creamy without being too rich. Replace 1 cup of half and half with ½ cup each heavy cream and milk.

Cheese: Both cheddar cheese and Parmesan add flavor to the cheese sauce. Pre-shredded cheese works well in this recipe.

Variations

You can replace the cheddar with any cheese you’d like, including Monterey Jack cheese or a shredded mozzarella cheese blend.
Replace the chicken with leftover turkey or ham. If using ham, reduce the salt in the recipe slightly.

How to Make Chicken Spaghetti

Cook pasta: Cook the spaghetti and drain.
Prepare sauce: Prepare the sauce (recipe below).
Assemble: Combine the spaghetti, chicken, diced tomatoes, and sauce in a greased casserole dish.
Bake: Top with more cheese and bake until bubbly.

If you’re short on time, this chicken spaghetti recipe can be made with a shortcut sauce.

Cook the vegetables as directed.
Add 3⁄4 pound Velveeta cheese, 10oz condensed cream of mushroom soup or cream of chicken soup, and drained tomatoes and cook until melted.
Skip the salt and add ½ teaspoon each of onion powder, garlic powder, and black pepper. You can also add a can of green chiles if you’d like.

Serving Suggestions

Salad: I love to serve this dish with a fresh salad—either green salad or Caesar salad.

Bread: Bread or garlic bread is great to sop up any bits of sauce and help stretch the meal further.

Leftovers and Meal Prep

Store leftovers in an airtight container in the fridge for up to 4 days.
Chicken spaghetti freezes very well and can be frozen before baking for up to 4 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!

If preparing ahead of time and freezing, line the baking dish with parchment paper and assemble the casserole.

Once frozen, lift the parchment paper and casserole from the baking dish, wrap it tightly with plastic wrap, and freeze. To bake, place the frozen block of chicken spaghetti back into the casserole dish.

Preheat the oven to 375°F. Grease a 9×13-inch baking dish.
Cook the spaghetti al dente in a large pot salted water according to package directions. Drain well, do not rinse.
Meanwhile, to make the sauce, in a large skillet, melt the butter over medium heat. Add onion, garlic, and bell pepper can cook until tender. Stir in the flour and Italian seasoning and cook for 1-2 minutes.
Gradually add the broth and half and half, a bit at a time, whisking until smooth after each addition. Bring to a boil and let boil 1 minute or until thick and bubbly.
Remove from heat and whisk in the Parmesan cheese, 1 cup cheddar cheese, and salt and pepper.
Combine spaghetti, chicken, cream sauce, and canned tomatoes. Mix well. Spread in baking dish.
Top with remaining 1 cup of cheddar cheese and bake for 25-30 minutes or until hot and bubbly.

Don’t overcook the pasta, it will cook more as it bakes.
Pre-shredded cheese does work in this recipe but shredding your own makes for a smoother sauce.
Sharp cheddar adds the best flavor.
