1 pound ground beef
1/3 cup dry bread crumbs
1/4 cup chopped onions
1 egg, beaten
1 teaspoon salt
1/4 teaspoon pepper
2 cups beef broth
1 large onion, thinly sliced
1 cup sliced mushrooms
3 tablespoons cornstarch
3 tablespoons water
Combine ground beef, bread crumbs, chopped onion, egg, salt and pepper in a bowl until evenly mixed. Shape beef mixture into 4 patties, about 3/4 inch thick.
Fry patties in a large skillet over medium heat until browned on both sides, about 10 minutes. Add beef broth, onion, and mushrooms; bring to a boil. Reduce head to low, cover, and simmer until patties are no longer pink in the center, about 10 minutes more. Transfer patties to a platter and keep warm.
Bring onion mixture to a boil. Mix cornstarch and water in a small bowl; stir into onion mixture. Cook and stir until gravy is thickened, about 1 minutes. Pour over patties to serve.
