Homemade Salisbury Steaks

0 In a mixing bowl, combine the ground beef, breadcrumbs, egg, Dijon mustard, ketchup, onion powder, garlic powder, dehydrated onion flakes, beef bouillon powder, and Worcestershire sauce. Use your hands to gently mix everything together until well combined.
1 Divide the mixture and shape it into 4 patties. Place the patties in a hot skillet over medium high heat and sear them for about 3–5 minutes on each side. Remove the patties from the skillet and set aside.
2 Add the sliced onions to the same skillet, stirring them so they are coated in the leftover oil. Cook for about 7–8 minutes, or until the onions become soft and lightly browned around the edges.
3 Sprinkle the flour over the onions and stir to combine. Continue cooking for another 2–3 minutes, stirring frequently.
4 Pour in the beef broth and add the Better Than Bouillon beef paste. Stir well and bring the mixture to a simmer. Return the patties to the skillet and let everything simmer for about 5 minutes. Serve over mashed potatoes and enjoy.
