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.

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!

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, place the frozen block of chicken spaghetti back into the casserole dish when you’re ready to bake it.

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.
