This Easy Salisbury Steak with Mushroom Gravy is the ultimate guest-worthy comfort food. Imagine an ultra tender, somewhat sophisticated burger that's drenched in luscious gravy. Superbly flavorful yet easy to make!
In a heavy large skillet, heat 2 TB olive oil over medium high heat. Add onions and stir 2-3 minutes. Add garlic and stir 1 minute. Reserve half of this mixture for later.
Add the other half of the garlic/onion mixture to a large bowl with ground beef. Add breadcrumbs, beaten egg, mustard, ketchup, salt, Worcestershire sauce, and pepper to the bowl. Stir to combine mixture well.
Form beef mixture into 7 even sized patties, about 1/2" thick each.
In heavy large skillet, add another TB of oil and heat over medium high heat. Cook beef patties 3 minutes per side or until nicely browned on both sides and fully cooked through -- do this in 2 batches, adding olive oil as needed
Make Gravy
While patties are cooking, make the gravy: In a separate saucepan, add the butter over medium high heat. Add flour to melted butter and whisk until mixture is a thick roux.
Add broth, mustard, Worcestershire, and sugar to the saucepan; constantly whisk until mixture is smooth. Bring to a boil and let sauce boil about 5 minutes or until thickened.
Add reserved onion/garlic mixture from earlier, plus mushrooms, stirring to combine well. Add salt and pepper to taste, if needed. Pour finished gravy over beef patties in original skillet and heat just to warm through.
Notes
When making the beef patties, make sure to handle the meat gently and do not overwork it. This will help to keep the patties tender and juicy.
If gravy is too thick, add a bit more beef broth; if it's too thin, let it simmer a bit longer until it reaches your desired consistency.
Serve your Salisbury steak with a side that can soak up the delicious gravy, like our Creamy Mashed Potatoes.
