Not all Swiss steak recipes include mushrooms, because any other sauce can substitute the common mushroom sauce. Betty Crocker's Swiss steak recipe is one example of this.
To make Betty Crocker's Swiss steak, cut 1/2 pound of boneless beef into serving pieces and scatter a mixture of 3 tablespoons flour, 1 teaspoon of ground mustard and 1/2 teaspoon of salt over the meat. Pound the mixture into both sides of the beef with a meat mallet. Cook the beef in a skillet with oil over medium heat until brown. Add 1 can undrained whole tomatoes and 2 cloves of garlic, breaking up the tomatoes as they soften. Reduce heat once boiling, then cover the stew and simmer for 75 minutes. After this time, add 1 cup water, 1 large sliced onion and 1 sliced large bell pepper. Heat to boiling, then reduce heat and simmer for five additional minutes.
