Add the noodles to the slow cooker and stir to evenly coat the noodles with the sauce and chicken. Top the casserole with the cheese and add the lid until the cheese has melted and noodles are tender to your liking. Serve topped with the fried onions.

Notes
Chicken Casserole On the Stove
In pot mix together the soups, sour cream, and seasonings. Submerge the chicken into the sauce. Cover with a lid over medium heat so it is bubbling slowly so the meat can cook until it is fork tender enough to pull apart, about 30 minutes depending on thickness.Once meat is shredded, add frozen vegetables and submerge. Allow to bubble until veggies are as tender as you like, about 10 minutes. Boil noodles 'til al dente in a pot on the stove separately. Drain and add into the meat and veggies pot. Fold together with half your cheese to melt. Serve with more cheese and fried onions on top of each bowlful.
