Tips to Make This Chicken Spaghetti Recipe

A couple of shortcuts have transformed my classic chicken spaghetti recipe into an easy weeknight option. And we’ve done it without compromising the flavor of the dish.

Using pre-cooked chicken saves about 30 minutes of cooking time.
Recipe-ready chicken broth or stock adds more flavor to the dish and makes up for not having liquid from cooking the chicken.
We recommend using freshly grated cheddar cheese it’s creamier and melts more smoothly than the pre-shredded cheese you find at the grocery store.
Cook the pasta just to al dente – it will finish cooking during the baking time. Overcooking the noodles before assembling the casserole may result in mushy noodles.
You might not need the reserved pasta cooking water . Only use it if the pasta mixture appears to be on the dry side. The dish should have a creamy consistency, but not too liquidy. If you forgot to save the water feel free to use broth or warm tap water in a pinch.

Ingredient Substitutions and Recipe Variations

I’ve successfully used my meal prep chicken, canned chicken breast, rotisserie chicken and Kirkland brand Grilled Chicken Breast Strips from Costco in this recipe. Leftover chicken also works well here.
Substitute with a different cheese or use a blend of cheeses if that’s what you have on hand. Just make sure it’s a “melty” kind of cheese like mozzarella or Monterey Jack.
If your people don’t like green peppers or onions, don’t use them. You can also substitute red peppers for the green.
For a smoky flavor, add 3/4 cup of cooked, chopped bacon.
Add a can of Rotel tomatoes for a pop of color and flavor.
For a spicy kick, add red pepper flakes or a couple dashes of cayenne pepper.

Can I substitute other soups with this recipe?

Yes, you can use 2 cans of cream of chicken or 2 cans of mushroom soups. Or lighten it up by using reduced-fat or reduced-salt soups.

Can I make this recipe in advance?

Yes you can! If you’re faced with an extremely busy day or week, it’s a breeze to prepare this easy pasta dish ahead of time. Prep it the evening before or in the morning to lessen the dreaded after work scramble. And it’s a great choice if you need to cook food for friends in need.

To prepare in advance, follow the steps up to baking. Cover the assembled dish and store it in the refrigerator until you’re ready to bake it. These casserole dishes with lids are fab for storing prepped casserole dishes in the frig.

To bake, remove the casserole dish from the frig about 15 minutes before baking and set it on the counter while the oven preheats. Remove the lid, pop the baking dish into the pre-heated oven and cook as directed. You may need to add a couple minutes to the bake time.

What to Serve with Cheesy Chicken Spaghetti

I like to serve this cozy meal with a simple Greek salad and garlic bread. If you’re feeling ambitious, round out the meal with a big bowl of fruit salad with honey lime dressing.

How to Store Leftover Chicken Spaghetti Casserole

After letting the dish cool, cover or transfer leftovers to an airtight container. Refrigerate leftovers for up to 3-4 days. Reheat in the oven or microwave until warmed through. You may need to add a little liquid if it’s on the dry side.
