Step 1

Place beef in 6-quart crockpot, add salt and pepper. Then add beef broth, mushrooms, onion, Worcestershire sauce, garlic, Dijon mustard, parsley and thyme. Mix well.

Step 2

Cook on low 8-9 hours, or high 4-5 hours. I prefer cooking the beef on low to make sure it's nice and tender.

Step 3

Cook egg noodles according to the package directions.

Step 4

Add the cooked and drained noodles to the crockpot as well as sour cream. Mix well. Let simmer for another 15 minutes, stirring occasionally.
