Ingredients for Chicken Spaghetti
- Pasta: I use spaghetti noodles, but you can use other varieties of pasta. Be sure to cook it al dente (firm) so it doesn’t overcook as the casserole bakes.
- Chicken: Use rotisserie chicken or leftovers you can also make baked chicken breasts to enjoy in this recipe.
- Vegetables: 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, but it also adds flavor—if using low-sodium, add extra salt.
- Half and Half: Half and half make 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.
How to Make Chicken Spaghetti
- Cook the spaghetti.
- Prepare the sauce (recipe below).
- Combine the spaghetti, chicken, diced tomatoes, and sauce in a greased casserole dish.
- Top with more cheese and bake until bubbly.
Leftovers and 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!

Notes
- 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.

- 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.
