Make the steaks. In a large bowl, combine the ground beef, breadcrumbs, ketchup, Worcestershire sauce, mustard, garlic powder, onion powder, egg, 1 tsp of salt (cut this to 1/2 tsp if using salted beef broth in the gravy), and 1/2 tsp of pepper. Mix gently until just combined and form into 4 oval-shaped patties. I usually make them half an inch thick, and press a divot into the center of each steak to help keep it from shrinking when it cooks. 1 Lb Ground Beef, 1/3 C Plain Breadcrumbs, 1 Tbsp Ketchup, 1 Tbsp Worcestershire Sauce, 1 tsp Mustard, 1/2 tsp Garlic Powder, 1/2 tsp Onion Powder, 1 Large Egg, Salt and Pepper to Taste
Heat the oil in a large skillet over medium-high heat.
1 Tbsp Vegetable Oil
Add the patties to the skillet and sear for 3-4 minutes per side. They don't need to be cooked through yet. Remove the steaks and set aside.
Make the gravy. With the same skillet, reduce the heat to medium. Add the butter and onions, along with a pinch of salt and pepper, cooking until the onions are softened and starting to caramelize. Roughly 8-10 minutes. If using the (optional) mushrooms, add them five minutes in to this cooking time. 1 Tbsp Butter, 1 Medium Yellow Onion, Thinly Sliced, 1 C Sliced Mushrooms, Salt and Pepper to Taste
Sprinkle in the garlic powder and flour, and stir to coat the onions. Cook for another minute.
1/2 tsp Garlic Powder, 2 Tbsp All-Purpose Flour
Slowly stir the beef broth in to form a gravy. Start with 1/4 C at a time to prevent clumps (a whisk might be useful here). Be sure to scrape up any crispy bits in the bottom of the pan.Stir until the first 1/4 C of broth is mixed in and the flour begins to form into a consistent slurry. Then stir in another 1/4 C and repeat. 2 C Beef Broth
Once all the broth is mixed in, add the ketchup and Worcestershire sauce. Bring to a simmer.
1 Tbsp Worcestershire Sauce, 1 tsp Ketchup
Add the patties back to the skillet, nestling them in the gravy.
Cover and simmer for 10 minutes, until the steaks are cooked through and the gravy has thickened to your liking. Note: at the end of cooking, if the gravy is too thin, cook a couple minutes longer, uncovered, to help it reduce down. If it is too thick, stir in a little more broth or water. Season the gravy to taste with salt and pepper.
Serve with mashed potatoes or egg noodles, topped with the onions and gravy. Classic sides for this are green beans or carrots.
