Ingredients for Chicken Spaghetti

Chicken – Use cooked chicken—rotisserie chicken makes this easy. You can also use leftovers or bake chicken breasts in the oven.
Pasta – I use spaghetti noodles, but you can replace them with any variety of long pasta.
Onion/Garlic – Use fresh if possible. Replace fresh with 1 teaspoon onion powder and ½ teaspoon garlic powder.
Rotel/Bell Pepper – These also flavor the casserole, and Rotel tomatoes add a bit of freshness.
Chicken Broth – This is the base of the sauce and adds both flavor and salt—if using low-sodium broth or stock, add extra salt.
Cream – Half and half or light cream makes the sauce creamy without being too rich.
Cheese – Both cheddar cheese and Parmesan add flavor to the cheese sauce. Pre-shredded cheese works well in this recipe.

Serving Suggestions

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

Leftovers and Meal Prep

Store leftovers in an airtight container in the fridge for up to 4 days.
This chicken spaghetti recipe 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!

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.

Cook ModePrevent your screen from going dark

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.

Pasta: Don’t overcook the pasta, it will cook more as it bakes.
Cheese: Pre-shredded cheese works in this recipe, but shredding your own makes for a smoother sauce. Sharp cheddar adds the best flavor.
To Make a Shortcut Sauce
Cook the vegetables (onion, garlic, bell pepper) as directed. Add 3⁄4 pound cubed Velveeta cheese, 10 oz condensed cream of mushroom soup or cream of chicken soup, and drained Rotel tomatoes. Stir until melted. Skip the salt and add ½ teaspoon each of onion powder, garlic powder, and black pepper.
