Baked Chicken and Spaghetti Casserole

This simple weeknight chicken spaghetti meal is a family favorite around our house.  In our kitchen, we often make it just as the recipe calls for.  But just as often we like to make little tweaks here and there, whether to add a little spice, a different cheese or toss in some leftover veggies.

Speaking of leftovers, this is the perfect recipe to whip out when you find yourself with leftover cooked chicken.  Whether you have cooked chicken breasts, crockpot shredded chicken, or a grocery store rotisserie chicken without a plan, they will all make an equally yummy casserole.

Another thing to love about this recipe?  It makes a perfect freezer meal!  Make one for now and one for later.  If you’re looking for some Cheap Dinner Recipes or some healthy chicken recipes, be sure to check out my list here for some dinner inspiration.

Key Ingredients

• Spaghetti – considering it is half of the name, we generally stick with spaghetti noodles here.  However, it will work with other pastas like linguine, penne or even shells.
• Chicken Broth – you can use store bought or homemade chicken stock or broth.
• Cream Cheese – this is part of what makes the sauce so creamy, so I prefer to use full fat cream cheese.
• Sour Cream – sour cream is also added to the sauce to add extra creaminess as well as a little tartness. Full fat or lite will work great.  You can also substitute a can of either Cream of Mushroom Soup or Cream of Chicken Soup!
• Parmesan Cheese – grated or shredded Parmesan cheese works best.
• Cooked Chicken – we love using either rotisserie chicken, or any leftover cooked chicken, because it saves time and dishes.  You can absolutely cook chicken breasts for this recipe specifically if you’d like.
• Mozzarella Cheese – you can shred your own or buy pre-shredded.  You can also try other types, or mixing and matching mozzarella, sharp cheddar cheese and Monterey Jack.

How to Make Chicken Spaghetti Casserole

1. Cook spaghetti.  Cook spaghetti noodles to al dente according to package instructions, drain and set aside.
2. Make the creamy sauce.  In a large pot over medium heat, add the chicken broth, cream cheese, sour cream, and garlic powder. Bring to a low simmer and stir until all ingredients are combined.  
3. Add chicken and spread into baking dish.  Remove from the heat, then add in the cooked spaghetti, Parmesan cheese, the diced chicken and half of the mozzarella cheese.  Mix to combine, then spread into a 9″ x 13″ casserole dish. 
4. Bake.  Top with the remaining mozzarella cheese and bake in a 350 degree preheated oven for 20-30 minutes, or until the cheese is melted and bubbly on top.
5. Serve.  Remove from the oven, garnish with fresh chopped parsley and serve hot.  Enjoy!

Easy Recipe Variations

Other than the substitutions we mentioned in the ingredients list, here are a few other ideas if you want to mix things up:

• Mexican Chicken Spaghetti – add diced tomatoes, green peppers and canned green chilis.
• Veggie Spaghetti Bake – skip the chicken and add sautéed mushrooms, bell peppers, zucchini, broccoli and/or spinach.
• Shrimp Spaghetti – instead of chicken, use small cooked shrimp.
• Chicken Spaghetti with Rotel Tomatoes – to many this is the classic way to make this casserole.  Just add a 10-oz can of Rotel Diced Tomatoes along with a small can of green chilis.

Storing and Reheating Instructions

• Refrigerator: cover any leftovers with aluminum foil and store in the fridge for up to 3 days.
• Freezer: you can freeze this dish before baking. Simply wrap well with plastic wrap and aluminum foil and store for up to 2 months.
• To Reheat: cover and reheat leftovers in a 350 degree oven for about 20 minutes. If you are baking from frozen, remove from the freezer for at least 30 minutes and then bake in a preheated 350 degree oven for 45 minutes – 1 hour.
