Sabrina’s Slow Cooker Salisbury Steak and Mashed Potatoes Recipe
Salisbury steak is a cherished memory for me as it is one of the first meals anyone ever cooked for me. I know that may not be a huge deal, but when you’re a chef people don’t cook for you. I have loved Salisbury steak ever since. It was also one of my favorite meals my moms group made when we were doing meal swaps together. So making this entire meal in one slow cooker (and a bowl) has become an awesome weeknight dinner for my family.

- 1/2 teaspoon Kosher salt , divided
- 1/4 teaspoon crushed black pepper , divided
- 2 tablespoons butter
- 1 yellow onion , sliced
- 8 ounces crimini mushrooms , sliced
- 2 cups beef broth

MASHED POTATOES
- 6 russet potatoes , scrubbed clean
- 4 tablespoons of butter
- 1/2 cup sour cream
- 1 cup whole milk or heavy cream
- 1/2 teaspoon Kosher salt
- 1/4 teaspoon ground black pepper
Instructions
SALISBURY STEAK
- Mix the ground beef with breadcrumbs, ketchup, mustard, beef base (if using), ¼ teaspoon Kosher salt and half the black pepper.
- Form them into four patties and add the patties to a heavy skillet or the stove safe slow cooker insert.
- Cook the patties on medium-high heat until browned on both sides, 4-5 minutes per side.
- Place the patties into ½ of the slow cooker.
- Add the butter to the pan and add the rest of the salt and pepper to the onions and mushrooms.
- Cook for 4-5 minutes, stir, then cook an additional 4-5 minutes.
- Add to the slow cooker on top of the cooked beef patties.
MASHED POTATOES:
- Add a piece of 12×12 inches of foil into half of the slow cooker.
- Place the clean and scrubbed potatoes into the slow cooker and press down tightly with another sheet of foil.
- Cook on low for 4 hours.
TO FINISH:
- Uncover the foil and remove the potatoes. Peel if you’d like by rubbing off the skin with a paper towel or leave the skin on.
- In a bowl mash the potatoes with a potato masher.
- Add in the butter, sour cream, milk, salt and pepper and mash until desired consistency (I mashed the pictured potatoes for 1 minute).
- Add the potatoes back to the slow cooker in the foil still lining the bottom.
- In a cup mix the beef broth, 2 teaspoons of Worcestershire sauce and one tablespoon of cornstarch and add it to the beef patties.
- Cook on high for 20 minutes.
- Garnish with chopped parsley, optional.

Chefs Note
Browning the beef before placing it into the slow cooker is an absolute must for this recipe. Not only does it enhance the flavor of the dish, it also enables the meat to hold up better during the cooking process as well as looking more visually appealing when it is finished cooking.

About this Recipe
Slow Cooker Salisbury Steak and Mashed Potatoes in a single slow cooker with mashed potatoes, rich gravy, mushrooms and onions over tender beef patties. Does it get any better than this?
Recipe Tips & Tricks
- Brown the mushrooms and onions before you add them to the slow cooker to get a huge boost in flavor. If you don’t have time to do that, place them under the beef patties with butter cut into slices on top of them with the salt and pepper.
- Speed this recipe up by taking the liquid and putting it in a small saucepan. Add the broth, cornstarch and Worcestershire sauce and cook on medium heat until thickened and pour over the beef, mushrooms and onions.
What to Pair With
This slow cooker dinner already comes with protein and a starchy side but if you want to add some extra veggies to your family table tonight I recommend adding Sautéed Green Beans or Tin Roof Bistro Brussels Sprouts. If you have some extra time on your hands, add some Crusty French Bread Rolls to soak up all of the yummy gravy.
How to Store
- Storing: You can keep it on warm for 4 hours or up to 2 hours at room temp. Place any leftovers in an airtight container and refrigerate for up to 3 days.
- Reheating: Reheat in a slow cooker, covered on low, until hot. You can also heat it on the stove top, in the microwave or oven. Stir occasionally to make sure it heats up evenly.
- Freezing: Store leftovers in a freezer-safe container for up to 3 months. Thaw in the refrigerator overnight before reheating.
Variations
- French Onion: You can swap out the broth mixture and onions for 2 cans of French Onion Soup to make prep faster.
- Potatoes: I like to remove the skin from the potatoes after cooking but you can keep them off if your family likes them. Alternatively, you could also use baby red potatoes, Yukon Potatoes, or Baby Potatoes in this recipe.

I travel and work on the road in construction. The slow cooker has become essential.
I made this yesterday. After a 12 hour day it smelled lovely when I opened the door at the end of the day. It tasted yummy.
I highly recommend it.
Glad you enjoyed the steak and potatoes Craig!
Hamburger patties were great BUT the potatoes were no where beer being done!! I ended up with very lumpy potatoes, TERRIBLE
This is probably a silly question but do you cook this with the lid on the slow cooker?
No silly questions in cooking! You do use a lid on the slow cooker. If you try it, I’d love to hear how it turns out!
I’m fixing this for Valentines tonight. Only change is I went and thickened the broth and poured it over the meat patties and cooked onions and mushrooms and slow cooked them all together. Taters will be done separately.
I had this recipe on High for 4 1/2 hour cause I knew the potatoes would not get done on low for 4 hours. BUT they were not even done on high for 4 hours. This recipe needs to be revised.
Does this create a gravy too?
Yes but you can always thicken it up to your liking on the stovetop with some butter and flour.
I want to make this but my crock pot (slow cooker) instructions specifically say to Never Use Without Liquids in it. Will it hurt the recipe to add beef broth when you place the patties in the pot during the 4 hour cook time?
No, it won’t hurt the recipe. 🙂
This Salisbury Steak recipe that is to be made in a slow cooker, but the only times given for cooking are 4-5 minutes. That really doesn’t make much sense if your using a slow cooker. It sounds good but I would like a corrected recipe, please…..
I think the recipe plug in I’ve been using is having a glitch. I’ll edit it and hopefully it’ll stick. It should read hours.
Thanks for letting me know.
Excited to make this recipe tonight! Just wondering, how long do you keep the patties in the slow cooker?
Everything will cook at the same time in the slow cooker for 4 hours. Hope this clears up any confusion. I hope you enjoy it!
Just wondering can I peel the potaties first before putting them in the slow cooker..making this recipe today.thanks
Ugh, I missed your question. So sorry. I know you already made it but I take the skin off the potatoes after they’re done cooking but if you like them they’re totally fine to leave on. Hope you enjoyed it!
What a DELICIOUS meal! I would have never thought you could make the potatoes AND steak in the slow cooker at the same time!
Thanks, Erin! Enjoy!!
What a great comfort food dish! My family will love this!
Thanks, Krista!
What a nice memory you have! This looks wonderful, and I hadn’t thought about making it in a slow cooker! Great idea!
Thanks, Patricia!
Perfect comfort food! And I love that you made both the steaks & the potatoes in the slow cooker- so convenient! 🙂
Definitely saving this to make for my husband!!
I adore that you made this in the slow cooker–along with the mashed potatoes. This is just SO smart.
I love my slow cookers, that’s for sure!!
OMG – Talk about comfort food and made my favorite way; in a crock pot. I so enjoy your recipes and amazing photography and looking forward to more.
Thank you so much, Raschell! That’s so sweet of you to say.
