My family loves this meal....after visiting Elvis's Graceland, I saw this was one of his favorite meals and decided to make up a recipe of my own. I serve it with mashed potatoes, super sweet corn, and a yeasty dinner roll! Great Sunday Dinner!
In a large bowl, mix together the ground beef, egg, breadcrumbs, parmesan cheese, pepper, salt, onion & garlic powders, and worcestershire sauce.
Form into 8 balls, and flatten into patties. In a small bowl with the flour, dip the patties in the flour until the whole patty is nicely covered with a light covering of flour.
Heat the oil in a large skillet over medium heat. Fry the patties and the onion slices in the oil until patties are nicely browned. About 4 minutes each side...I fry them a little longer...I like them crispy! Remove the beef patties to a plate and keep them warm.
Take the remaining flour and sprinkle 2 to 4 tablespoons over the onions and drippings in the skillet. Stir in flour with a fork or whisk, scraping bit of beef off of the bottom as you stir.
Gradually mix in the beef broth. You can season to taste with seasoning salt or your favorite seasoning.
Simmer and stir over medium-low heat for about 5 minutes, until the gravy thickens. Turn heat to low, return the patties to the gravy, cover, and then simmer for another 15 to 20 minutes.
