Crock Pot Beef Stroganoff

Crock Pot Beef Stroganoff
1 lb beef (I like to use stew meat)
2 tbsp butter
1 1/2 cup beef broth
1/4 cup red wine
2 tbsp tomato paste
2 tsp garlic
1 tsp salt
1 tsp pepper
1 cup chopped mushrooms
1/2 cup onion
3 tbsp flour
1 cup sour cream
Pasta

Dredge beef in flour, salt & pepper. Melt butter in skillet and brown beef & onion. After browned pour into crock pot. Use red wine to deglaze the pan and pour in crock pot.
Place all other ingredients (except pasta and sour cream) in crock pot and stir
Cook on low for 5-6 hours
Add sour cream, cover and cook on low for 30-45 minutes (do not allow mix to boil)
Prior to eating cook pasta, serve beef stroganoff over pasta
