French Onion Soup Salisbury Steak

French Onion Soup Salisbury Steak pairs tender beef patties with a savory skillet gravy full of soft yellow onions. One packet of dry French onion soup mix seasons both the meat and the gravy. Sear the patties first, then finish them in the sauce so the browned bits from the skillet flavor every spoonful.

How to Make Tender Salisbury Steaks

Gently mix the ground beef with panko, beaten egg, Worcestershire sauce, and half the onion soup mix. Shape four oval patties about ¾ inch thick and press a shallow indent into the center of each one. Sear for 3 to 4 minutes per side, then set the patties aside while you make the gravy in the same skillet.

How to Make French Onion Gravy

Cook the sliced onion in butter until soft and lightly golden, scraping up the browned bits as you stir. Sprinkle flour over the onions and stir for a minute. Gradually whisk in the beef broth, remaining soup mix, and Worcestershire sauce to make a smooth gravy.

Return the patties and their juices to the skillet. Partially cover and simmer gently for 10 to 15 minutes, until the gravy thickens and the center of each patty reaches 160°F (71°C).

What to Serve with French Onion Salisbury Steak

Set a patty over mashed potatoes or buttered egg noodles and spoon the onions and gravy over the top. Finish with chopped parsley if you like.

Instructions

  1. In a large bowl, gently mix the ground beef, panko, beaten egg, 1 tablespoon Worcestershire sauce, and half the dry onion soup mix just until combined.
  2. Divide the mixture into four portions and shape each into an oval patty about ¾ inch thick. Press a shallow indent into the center of each patty.
  3. Heat the olive oil in a large skillet over medium-high heat. Sear the patties for 3 to 4 minutes per side, until browned. Transfer them to a plate to finish cooking in the gravy later.
  4. Reduce the heat to medium and melt the butter in the same skillet. Add the sliced onion and cook for 5 to 7 minutes, stirring and scraping up the browned bits, until softened and lightly golden.
  5. Sprinkle the flour over the onions and stir constantly for 1 minute. Gradually whisk in the broth, then stir in the remaining onion soup mix and 1 tablespoon Worcestershire sauce. Bring to a gentle simmer.
  6. Return the patties and any juices from the plate to the skillet. Reduce the heat to medium-low, partially cover, and simmer for 10 to 15 minutes, until the gravy thickens and the patties reach 160°F (71°C) in the center.
  7. Spoon the onion gravy over the patties, garnish with parsley, and serve hot.
