The sauce is what makes the whole thing great!

If you’ve had salisbury steak before, you’ll know it’s a delicious meal that’s perfect for any weeknight dinner. The steaks are made of ground beef, then typically served with a tasty brown gravy along with any other sides you’d like to serve it with, but we found a way to make it even better. Turning it into a casserole is a way to simplify and streamline the whole process, while still getting a delicious meal that will warm everyone up and fill those hungry tummies.

While our version of salisbury steak casserole is still ground beef-based, we make a quick brown sauce – trust us, it tastes so much better than it looks! – and incorporated mashed potatoes, turning this into a full meal. So let’s break down the sauce: while you could absolutely make a brown gravy from the beef drippings, we used French onion soup, cream of mushroom soup, dry onion soup mix, ketchup and Worcestershire sauce to make the sauce that goes with the salisbury steak. While it really doesn’t look like much, and it might not sound like these ingredients all go together, but trust us, they do….

Serves 6-8 | 45 minutes


3 cups mashed potatoes, leftover or store-bought
1 (10.5 oz.) can French onion soup, divided
1 1/2 pounds lean ground beef
1 (10.5 oz.) can cream of mushroom soup
1/2 (1.4 oz.) packet dry onion soup mix
1/4 cup all-purpose flour
1/4 cup ketchup
2 tablespoons Worcestershire sauce
1 teaspoon mustard powder
1/2 teaspoon onion powder
1/2 teaspoon garlic powder
1 (14.5 oz.) can french cut green beans, rinsed and drained
kosher salt and freshly ground pepper, to taste


Preheat oven to 350º F and lightly grease a 9×13-inch baking dish.

In a medium bowl, whisk together 2/3 can French onion soup, mushroom soup, dry onion soup mix and flour, stirring until mixture is smooth.

Season with mustard powder, onion powder and garlic powder, then mix in ketchup, water and Worcestershire sauce.

Season beef and cook in a large pan or skillet over medium-high heat until browned, then stir in 1/3 French onion soup.

Drain fat, if necessary.

Transfer beef to prepared 9×13 and spread into an even layer, then spread soup mixture on top.

Gently place green beans on top of soup mixture, then spread mashed potatoes on top.

Place baking dish in oven and bake for 20-22 minutes, or until hot and bubbly.

Remove from oven and serve hot.
