Comfort food at its best!! Mom's chicken casserole recipe is a tried and true family favorite from my childhood and is now a favorite of my kids as well! It is hearty enough to stand on its own as a one dish meal and is easy to throw together in a pinch. You can cook your chicken beforehand or even grab a rotisserie from the store. The creamy pasta and cheese makes this the perfect comfort food. And since the recipe makes a large amount, you might even have leftovers for lunch the next day!
If cooking your own chicken, drizzle both sides of chicken breasts with olive oil, salt, and pepper. Cook on 350 degrees for about 20 minutes or until chicken is cooked through. When cool enough to handle, shred the chicken and set aside. If using a rotisserie, shred about 2-3 cups of chicken.
Cook spaghetti noodles according to directions on package.
While the pasta is cooking, mix sour cream, cream of chicken soup, and shredded cheese together and set aside.
When pasta is done, add it and shredded chicken to sour cream/soup mixture. Mix well. Once it is mixed, pour mixture into 9x13 casserole dish.
Crush the Ritz crackers and pour them on top of the casserole.
Melt the butter, if using, and pour it over the top of the crackers.
Bake for 20 minutes at 350 degrees or until bubbly along the edges.
