Mix up the cream of chicken, rotel, melted butter, Parmesan cheese, garlic powder and chicken broth in the bottom of the crock pot.
Place the chicken breasts into the mixture.
Cook on low for 8-12 hours, or on high for 4-6 hours.
About 45 minutes to an hour before serving, take out the chicken and shred it, and cook the spaghetti noodles and add them. Put everything back in and mix everything and allow to continue cooking for about 45 minutes to an hour.
Serve and sprinkle with shredded cheese pair with a salad and garlic bread for an easy meal.
