PREPARATION:
1. Combine the ground beef, breadcrumbs, finely chopped onion, milk, egg, Worcestershire sauce, garlic powder, salt, and freshly ground black pepper in a mixing bowl. Mix until all of the ingredients are properly combined.
2. Form the mixture into oval or round patties 1/2 to 3/4 inch thick. This recipe makes 4-6 patties, depending on the size you choose.
3. Brown the beef patties on all sides in a pan over medium-high heat. This process is used to sear the patties and increase their taste. Put the browned patties in the slow cooker.
4. Whisk together the condensed cream of mushroom soup, dry onion soup mix, and beef broth in a separate basin until thoroughly blended. If you want a thicker sauce, add 2 tablespoons of all-purpose flour at this point.
