Salisbury Steak Casserole Recipe

Classic Salisbury steak might bring up memories of a tv dinner warmed on a crumpled aluminum tray, but that misses the mark. By a long shot. Not sure your age, but I remember these and have had a few in my days.

Full of tender ground beef perfectly coupled with mashed potatoes, I mean, right there you can’t go wrong. But then, bake in with a tasty brown gravy and…

You begin to understand why this might be one of the all time great comfort foods.

If you like homemade but don’t want to make homemade salisbury steaks, then this recipe is for you.

My other favorite comfort food casseroles with ground beef are my French Fry Casserole and my Big Mac Casserole with Tater Tots. Both are kid friendly which is a BIG PLUS!

Easy Casserole Recipe

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. The whole family is going to love it like this homemade hamburger helper.

  2. Bake at 350F for 25-30 minutes or until the casserole is bubbly and the internal temperature has reached 165F.

How long does it last?

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 I 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 individual portions if possible. Those are easier to reheat and you don’t end up with leftovers of leftovers.

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.

Tips for the Best Casserole

  • 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.
  • If the meat mixture seems a little dry, add a tablespoon or two of beef broth.
  • 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.
