8 ounces mushrooms
1 cup thin sliced yellow onion
¼ cup butter
1 teaspoon Worcestershire sauce
¼ cup flour
1 cup sour cream
1 1/2 cup beef stock
1 bay leaf
Cooked egg noodles
1. Sauté the beef in the butter at medium-high heat. Caramelize the beef until brown in color.
2. Add the onions and mushrooms. Cook for 2 minutes then add 1 cup of beef stock. This should deglaze you pan. Reduce the mixture to a simmer. Add the bay leaf and Worcestershire sauce then cover and simmer for 15 minutes.
3. Combine the flour and remaining ½ cup beef stock in a small bowl. Mix well until smooth.
