The main dish for our Russian meal was Beef Stroganoff. From what I read, the traditional way is to serve it with potatoes. I decided to go with egg noodles because the soup had potatoes in it.
3 tablespoons oil
3 small onions, chopped
1 1/2 lbs beef, sliced in short, thin strips
1/4 cup flour
2 teaspoons dry mustard
2 cups beef broth
1/2 cup sour cream
Saute onions in oil until golden brown.
Add beef. Cover & cook over medium heat for 5 minutes. Remove lid & cook for an additional 5 minutes. Salt & pepper to taste. Remove from heat.
Melt butter in saucepan. Stir in flour & dry mustard. Whisk in broth. Cook, stirring constantly, until thickened. Stir in sour cream, mix well, and combine with meat.
