If you love Salisbury steak, you won't be able to resist this casserole. Built much like a shepherd's pie, the recipe below combines the flavors of steak, mushrooms, onions, and gravy in a layered casserole. Topped with creamy mashed potatoes and baked, it's a delicious play on the classic.
As with classic Salisbury steak, the secret of success in this recipe is undoubtedly the sauce. To make it, this recipe calls for condensed beef broth and condensed cream of mushroom soup, both of which effortlessly add richness and depth of flavor mirrored by the sautéed mushrooms and onions that are cooked with the beef itself.
Salisbury steak casserole
6
20 minutes
40 minutes
1 hour
1 tablespoon vegetable oil, divided
2 pounds ground beef
1 tablespoon butter
1 cup button mushrooms, diced
2 onions, diced
1 (10 ½) ounce can condensed beef broth
1 (10 ½ oz) can condensed cream of mushroom soup
2 teaspoons Worcestershire sauce
3 cups water
¼ cup salted butter
1 ½ cups milk
8 ounces instant mashed potato mix
Preheat the oven to 400 degrees Fahrenheit.
Heat half of the oil over high heat in a medium saucepan. Add the beef and brown on all sides. Drain the beef and discard the fat; set the drained beef aside.
In the same pan, heat the remaining oil with the butter over medium heat. Add the mushrooms and onion and cook, stirring occasionally, until slightly browned, about 15 minutes.
Return the beef to the pan with the mushrooms and onions, and add the broth, condensed soup, and Worcestershire sauce. Stir until well combined.
Transfer the meat mixture to a greased 9x13-inch casserole dish, and spread out in an even layer.
Heat the water and butter in a saucepan. When it comes to a boil, remove from the heat and add the milk. Whisk in the instant mashed potato mix. Allow to set for a minute before mixing once more spreading in an even layer on top of the meat mixture.
Bake for 20-25 minutes, until slightly browned on top.
