To your slow cooker, add the stew meat. Sprinkle salt, pepper, and paprika over top. Add onion and garlic.
In a medium mixing bowl, whisk together cream of mushroom soup, beef broth, and Worcestershire. Pour this over the beef.
Cook on high 3-4 hours or low 6-8.
Before the last hour of cooking, add cream cheese, and sour cream. Stir to combine. Let this melt for the remainder of the cook time, and stir well.
Once cooking has finished, boil egg noodles according to package directions (we typically use 3/4 of a package). Add cooked noodles to the slow cooker and stir well to combine.
Top with fresh chopped parsley.
