Beef Stroganoff

I have been looking for a good Beef Stroganoff recipe that didn't include a lot of 'cream of soups' since Noah can't have it and I finally found one I love. Aaron even went back for seconds:)

3 lb. beef round steak, 1/2 inch thick
1/2 cup flour
2 teaspoons salt
1/8 tsp pepper
1/2 tsp dry mustard
2 medium onions, sliced thin
1/4 cup flour8 oz sliced mushrooms
1 can condensed beef broth (10.5 oz)
3 tablespoons dry white wine
1 1/2 cup sour cream

Trim all excess fat from steak and cut into 3 inch strips about 1/2 inch wide. Combine 1/2 cup flour, salt, peppers and dry mustard. Toss with the steak strips to coat. Place coated strips in a crock pot; stir in onion rings and mushrooms.Add beef broth and wine, stir. Cover and cook on low for 8-10 hours.Before serving, mix the sour cream with 1/4 cup of flour then stir into the crock pot. Serve with rice or noodles.
