3 tablespoons olive oil
1 medium onion, thinly sliced
1 1/2 to 2 pounds round steak
Salt and pepper
1/3 cup all-purpose flour
3/4 cup beef broth
1 tablespoon ranch dressing mix
1/2 cup sour cream
Heat oil in large heavy, non-stick skillet. Fry onions until limp. Remove from pan and set aside.
Cut meat into serving size pieces. Sprinkle both sides with salt and pepper. Dust lightly with flour and beat it into meat with edge of a saucer. Brown on both sides, adding more oil if needed. Return onion to pan with meat. Add beef broth, cover and simmer 50 to 60 minutes or until meat is very, very tender, adding a little more broth if needed.
Combine ranch dressing mix and sour cream. Remove meat to platter. Stir sour cream mixture into meat juices. Heat through until bubbly. Pour over meat and serve.
Serves 4 to 6.
