In a skillet brown your ground beef until no pink remains, drain and pour into your slow cooker.
Add can of cream of mushroom soup, onion soup mix, W. sauce, garlic and beef broth - stir together.
Set to low for 4 hours. Then lift lid and stir in sour cream. Recover and set pot to warm.
Boil egg noodles in a pot over medium high heat until cooked to al dente. Drain and pour in (3/4 of the noodles for a thicker sauce coating or all of them to feed more people) Serve!!
Notes
I like to sprinkle some French's fried onions on the top of each bowl when serving it for a bit of crunch and added flavor too!
