Making A Salisbury Steak Casserole

As casseroles go, Salisbury steak is one the easiest. You mix some sautéed seasoned ground meat with condensed soup to create the brown gravy style sauce, and layer that with mushrooms, onions, and green beans.

Top it with mashed potatoes, then bake it about 20 to 25 minutes and serve.

It is like a side dish, main course, and salad all composed into a single bite that delivers on every trip to the taste buds.

How to make Salisbury Steak Casserole

  1. Preheat oven to 350F. Spray a 9×13 pan with nonstick spray.
  2. In a large skillet, over medium high heat, cook the ground beef and ⅓ can of french onion soup until the meat is no longer pink. Remove to a bowl and drain excess fat if desired.
  3. To the skillet add the butter. Cook the mushrooms and onions in the butter until the mushrooms are brown and the onions are tender.
  4. Spread the ground beef in the prepared 9×13 pan.
  1. In a medium bowl, combine the remaining french onion soup, onion soup mix, condensed mushroom soup, ketchup, water, Worcestershire sauce, flour, salt, pepper, and mustard powder. Stir to mix.

  2. Pour soup mixture over the meat mixture in the 9×13 and spread into an even layer. Top the soup mixture with the onion and mushrooms.

  3. Drain and rinse the canned green beans. Spread them over the mushrooms and onions.
  1. Top with prepared mashed potatoes and spread into an even layer.
  2. Bake at 350F for 25-30 minutes or until the casserole is bubbly and the internal temperature has reached 165F.
  3. Remove and let set for 3-5 minutes (it will be runny a little). Serve warm and enjoy.

Got Leftovers?

Storage: Store in the refrigerator in an airtight container for up to three days.

Reheat: Reheat in the microwave in 30 second intervals until warmed through. Warm large portions in the oven at 350F for 15-20 minutes or until heated through.

Freeze: Freeze in air tight containers for up to 3 months. Thaw overnight and reheat.

Can you freeze it?

Want to save leftovers? Good luck. You might have to double up the recipe to save some for later. Just warning you ahead of time.

But if you do have some leftover, and you want to freeze it, then no problem. This casserole is one of the more freezer friendly casserole recipes.

With all leftovers destined for the freezer, remember these helpful tips.

  • Store in sealable containers. The more airtight, the longer it keeps in the freezer. You can store this casserole up to two months in the right containers.
  • Make sure to label the container with the date and even the name of the dish.
  • Store in portions if possible. Those are easier to reheat and you don’t end up with leftovers of leftovers.

Why is it called Salisbury Steak?

This dish has origins in Germany, but an English gent with the last name Salisbury gets credit for invented it over 100 years ago. You know it is a certified comfort food because it really hasn’t changed much in all those years.

Some folks get a mountain, a monument, or even a road named after them. But something as universally beloved as Salisbury steak? Well, that seems like a lot more of an honor at the end of the day if you think about it.

What’s the difference between salisbury steak and hamburger steak?

Although some people view “hamburger steak” and “Salisbury steak” as the exact same thing, there are subtle differences.

Yes, both involve ground beef, but usually Salisbury includes some sort of filler, in this case flour. But, breadcrumbs are also commonly used.

How is it different from meatloaf?

Meatloaf and Salisbury steak have a little in common as well. However, meatloaf typically involves a mix of meats, like pork and beef and lamb, or turkey and venison.

Some recipes mix beef, onions, and spices, while some are just meats. Hence, the term meatloaf.

Best Casserole Tips

  • If you want to brown the top just a bit more, then stick it under the broiler for the last few minutes. Keep an eye on it though so it doesn’t burn the top.
  • To make clean up easier, then pre-coat your casserole pan with a light spray of cooking oil.
  • Make sure to strain the ground beef after cooking it. There is enough liquid in the dish that you don’t need extra water and oil.
  • You can garnish the top with some chopped parsley to sprinkle some color onto it.
  • Let this sit a few minutes after removing from the oven. This allows everything to thicken a bit more so it is easier to serve.
