Take a large bowl. Add ground beef, breadcrumbs, egg, and milk. Mix gently with your hands. Do not overmix. This keeps the patties soft and juicy.

Now add chopped onion, garlic, salt, pepper, and Worcestershire sauce. Mix again until everything combines well. The mixture should feel soft but hold shape easily.

Divide the mixture into equal parts. Shape each part into oval patties. Keep them slightly thick. This helps them stay juicy while cooking.

Heat a skillet on medium heat. Add a little oil or butter. Place patties in the pan. Cook each side for 4–5 minutes until nicely browned.

Take the patties out and place them on a plate. Let them rest for a few minutes. This keeps the juices inside the meat.

In the same pan, add butter. Let it melt. Add flour and stir well. Cook for one minute until it turns light brown.

Slowly pour in beef broth while stirring. This prevents lumps. Add ketchup and mustard. Mix until smooth and thick.

Let the gravy cook on low heat. Stir often. It will become rich and smooth. The smell will be amazing.

Place the cooked patties back into the gravy. Spoon gravy over them. Let them simmer for 10 minutes.

Turn off the heat. Serve the Salisbury steak warm with your favorite side dish. Enjoy every bite.
