Salisbury Steak Casserole
Hearty Salisbury steak casserole is an easy way to have your favorite comfort food without a lot of fuss. Juicy ground beef, simmered in French onion soup, mixed with veggies, and topped with fluffy mashed potatoes, all in a single dish!
Classic Salisbury steak might bring up memories of a tv dinner or two that I have eaten. Yes, my parents ran a restaurant, but we still ate convenient comfort food. I did, especially when I was home along after school.
I couldn’t resist the ground beef patty and that gravy that I usually stirred into the mashed potatoes. Right along with my peas.
You can certainly understand why it’s so delicious, and something I still eat every now and then (yes, I mean the tv dinner!) and enjoy every bite. I have upgraded mine to the Trader Joe’s version, but still makes my heart and belly happy.
If you like salisbury steak but don’t want to take the time to make those patties, 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, like this homemade hamburger helper. which is a BIG PLUS!

Ingredient Notes
- Ground beef – Substitute hamburger patties or even ground turkey like these turkey salisbury steaks.
- Green beans – I like to use the french style cut ones to make it “fancy” but feel free to use what you prefer. If you use the canned ones, I suggest rinsing and draining them really well. Frozen ones work great too!
- Mashed potatoes – Make them fresh, use up those leftover ones, or if you’re short on time, buy some already made at the store.
- Cream of mushroom soup – Substitute cream of onion soup if needed.
- French onion soup – Swap out for canned brown gravy and onions.

How To Make Salisbury Steak Casserole
- Preheat oven to 350F. Spray a 9×13 pan with nonstick cooking spray. In a large skillet, over medium-high heat, cook the lb 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.
- Spread the ground beef in the bottom of casserole dish.
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.
- Drain and rinse the canned green beans. Spread them over the mushrooms and onions. Spread prepared mashed potatoes over the top of the casserole and spread into an even layer.

How To Store
Any leftovers can be stored in the refrigerator in an airtight container for up to three days. 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 in airtight containers for up to 3 months. Thaw overnight in the refrigerator and reheat. My favorite way to do this is in single portions. That way I can thaw them when my husband is traveling or I am craving it for lunch.
Serving Suggestions
I love this all on its own but if you need to stretch the budget a bit or want something on the side, I recommend a big salad, maybe some roasted veggies, and some crusty bread to soak up the yummy gravy.
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 spray your casserole dish with a light spray of cooking oil.
- If the meat mixture seems a little dry, add a tablespoon or two of beef broth.
- 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.
