Salisbury steak is one of those classic comfort foods that I’ve loved since I was a kid.

Tender beef with a savory gravy paired with mashed potatoes? What’s not to love?

Well, mushrooms. I don’t love mushrooms. So I leave them out of my version…but if you want to add some in, go right ahead!

I’ve been making Instant Pot mashed potatoes for a while now, which I love to serve alongside my Instant Pot Swiss steak.

So recently I decided to test out whether I could make the Salisbury steak in the Instant Pot while also cooking the potatoes, as a way to save a little time.

I use a similar technique with my Instant Pot shepherd’s pie, so I thought it was worth a try!

I love Brittany’s Salisbury steak recipe from Our Home Made Easy, so I adapted it to work in the pressure cooker (if you don’t have a pressure cooker, check out her recipe to see how to make it in a skillet).

It turned out SO well, and it was so easy since everything cooked at the same time!

And did you know you can also reheat mashed potatoes in the Instant Pot? A great way to warm up your leftovers!

This dish would also pair fabulously with these southern style pressure cooker green beans.

How to Make Instant Pot Salisbury Steak and Mashed Potatoes at the Same Time

Salisbury steak is one of the most comforting Instant Pot ground beef recipes, in my opinion!

You’ll start by combining some ground beef, french onion soup, breadcrumbs, an egg, black pepper, and garlic powder in a medium bowl.

I use my hands to mix everything well, but you could also use a stand mixer if you prefer. Then, shape that into four round patties.

In a separate small bowl, combine ketchup, french onion soup, water, Worcestershire sauce, and mustard powder. This will become that dreamy gravy!

In the insert pot of your Instant Pot, add some olive oil and heat it using the Saute function. Add in the four patties (if they won’t all fit, you may need to do this step in batches).

Sear the patties for a couple of minutes before flipping over to brown the other side as well.

Turn off the Saute function by pressing Cancel/Keep Warm.

The next step is really important–you need to scrape the bottom of the insert pot to make sure there are no brown bits stuck to the bottom of the pan. If not, you could get the dreaded BURN message during cooking.

You may be able to simply scrape a spatula under the patties to loosen any bits that are stuck. If there are a lot of pieces stuck to the pot, I would recommend removing the patties to a plate for just a minute, then adding in a couple tablespoons of water and scraping the bottom of the pot well to loosen any browned bits. Then return the patties to the pot.

Next, pour the ketchup and french onion soup mixture over and around the patties. Place the trivet on top of the patties.

In a baking dish or steaming basket that fits in your Instant Pot, place the cubed potatoes. Set the dish or basket on top of the trivet. Close the lid and set the vent to the sealed position.

Select a cook time of 10 minutes at high pressure.

While that is cooking, heat some butter, milk, and sour cream until the butter is melted (I do this in a saucepan, but you could also use the microwave).

Once the cook time is complete, perform a quick release of pressure. Carefully remove the lid and lift out the baking dish or steaming basket of potatoes.

Add a cornstarch slurry to the sauce in the insert pot, allowing it to thicken to the consistency of a gravy.

Mash the potatoes and combine them with the milk and butter mixture, mashing until the desired consistency is reached.

Serve the Salisbury steak and gravy with the mashed potatoes and, voila! Dinner is served.
