We had this the other night and I loved the sauce. Mmmm... Very yummy comfort food. I'm going to admit right now that it was not a hit with the kids, but they loved the noodles.:)
2 pounds beef chuck roast
a packet of beef marinade mix (plus the ingredients you need to make it) or 2 cans of Coke
1/2 teaspoon salt
1/2 teaspoon pepper
a stick of butter
1/4 cup finely minced onion
4 tablespoons flour
1 (10.5 oz) can condensed beef broth
1 teaspoon prepared mustard
8 oz sliced mushrooms
1/3 cup sour cream
1/3 cup chicken or beef broth
ground black pepper to taste
cooked egg or other noodles
Remove any fat from roast and cut into strips 1/2 inch thick and 2 inches long. Place in a ziplock bag with the meat marinade or Coke and let marinate in the fridge for 4-5 hours.
Remove meat from marinade and sprinkle with 1/2 teaspoon of salt and 1/2 teaspoon pepper. In a large skillet over medium heat, melt the butter and brown the beef strips. When they are browned remove meat with a slotted spoon and place in a bowl. Set aside. In the butter and beef drippings cook the onion for 3 to 5 minutes. Whisk in flour and pour in beef broth stirring constantly. Bring to a boil. Lower heat and add mustard. Add meat back into skillet and bring to a boil again. Cover and simmer for 1 hour or until meat is tender, stirring now and then.
Five minutes before serving stir in the mushrooms. Let them cook for a while then add sour cream and if it needs thinning up to 1/3 cup broth. Heat briefly and then adjust seasoning with pepper. Serve over noodles.
