- 1 pound boneless beef sirloin steak, cut into serving size pieces
- 1 tablespoon unsalted butter
- 2 cups sliced fresh mushrooms
- 1 tablespoon all-purpose flour
- 1 cup Swanson® Beef Stock
- Season the steaks as desired. Cook the steaks in a 12-inch nonstick skillet over medium-high heat to desired doneness. Remove the steaks from the skillet. Do not pour off any fat.
- Heat the butter in the skillet. Add the mushrooms and cook until they're tender. Stir in the flour and cook for 1 minute. Gradually stir in the stock. Cook and stir until the mixture boils and thickens. Serve the mushroom gravy with the steaks.
