Instant Pot Pot Roast with Mashed Potatoes and Gravy made with onion soup mix is the easiest, most incredibly tender and juicy roast paired with super creamy garlic mashed potatoes and savory brown gravy!

If you’re loving your instant pot as much as I am, you’ve gotta try Instant Pot Parmesan Chicken and Rice with Mushrooms, Instant Pot Shredded Chicken Tacos, and Instant Pot Chicken and Potatoes.

As much as I love an Instant Pot for the easy things, I also love it for the complicated things (which are still easy in an Instant Pot). What I mean is, sure easy things are still great to make, but what makes this appliance really stand out is its ability to take a typically complicated recipe and really simplify it and make it fast while keeping its integrity. I hope I didn’t lose you with my own confusing logic there.  

I’m not sure if Julia Child would agree with me, and she’d probably rather go the long route, but then again, she’s amazing. But in today’s fast-paced world that pulls us in a million directions every day, some things just need to be simplified. Like pot roast.

Even though we are coming off the holidays, I still have a hankering for bigger, heartier meals on occasion. I might not be roasting a whole turkey or preparing a glazed ham, but my leftovers are long gone and some nights I need some warm, filling comfort food.

The inspiration for this revolutionary meal came from all of the above needs, plus my family (kids included) really enjoys a nice, tender bit of beef now and then. This recipe doesn’t contain many ingredients (and most you probably have on hand). It’s also easy for kids to eat plain or even mix in with their mashed potatoes (if they are the kind of kids who will let their food touch). Plus it’s a great leftover to have on hand for so many other dishes (so you might to make this twice).

What Side Dishes Go Well With Pot Roast?

Well mashed potatoes (obviously). I’m a huge fan of the two together! However, the potatoes are the second part of this recipe and are easy enough to skip. Other side opportunities include:

  • If you want a little greens, consider adding this simple tossed green salad.
  • Roasted Brussels sprouts, green beans, or broccoli are easy to whip together while the roast is…roasting.
  • If you like the idea of potatoes but not mashed potatoes, you could make my favorite Company Potatoes or some simple roasted or baked ones in the oven with a little EVOO or butter and salt and pepper.  
  • Sometimes I like to go simple with my veggie sides and arrange cut-up carrots, celery, and cucumbers (or any veggies you like) to a dinner plate with some hummus or ranch dressing for dipping.
  • Other grain and pasta sides that go great with pot roast include couscous, white or brown rice, and wide egg noodles. (I like to put the shredded roast right on top with some of that gravy!)

What Can I Do with Leftover Pot Roast?

As I hinted to above, you’ll love the leftovers almost as much as you’ll love eating the dish the first time. My favorite ways to eat leftover pot roast, in no particular order:

  • On sandwiches. Boring, maybe. But add some banana peppers and a little mayo on top of that roast, slap it between two pieces of bread — any bread will do — and that’s one amazing sandwich!
  • Add shredded pot roast to a simple pasta dish.
  • Beef empanadas!
  • Savory tacos (hey, if I can, I’m making tacos!).
  • Add leftovers to a beef-based soup.
  • Lettuce wraps are a great, low-carb way to serve up this protein.

Customizations

I like to make recipes my own, and I’m sure you do, too. I used two packets of dry onion soup mix (or you can make your own in this recipe). But some other variations include:

  • Skipping the onion soup and instead adding onion powder, garlic powder, and horseradish (for a tangy roast).
  • Add onion powder, garlic powder, salt, pepper, and smoked paprika like I did in this pot roast recipe.
  • Make it simple with salt, pepper, olive oil, and sliced yellow onions and carrots.
  • Consider adding a dry rub to the roast before cooking — make your own or use a store-bought version.

What Cut of Meat Do You Use for Pot Roast?

I have used both chuck and rump roasts in this recipe. You can also try a round roast or a brisket, though both are tougher cuts of meat that might take a little longer in the pressure cooker, so take that into account if you choose different cuts of meat.

Ingredients 

  • 2-3 pounds chuck or rump roast , cut into 4-inch sections
  • salt and pepper
  • 2 tablespoons oil
  • 2 packets dry onion soup mix, (see note for homemade version)
  • 2 cups beef broth
  • 6-8 red potatoes, quartered, with skins on

Mashed Potatoes

  • 8 ounces sour cream
  • 2 teaspoons minced garlic , (or 1 teaspoon garlic powder)
  • 1 teaspoon salt
  • ¼ teaspoon pepper

Gravy

  • cup cold water + 4 tablespoons corn starch
  • 1 teaspoon salt
  • ¼ teaspoon pepper

Instructions 

  • Set instant pot/pressure cooker to saute. Salt and pepper the meat generously all over. Drizzle oil in the pot and add meat chunks, allowing to brown for 2-3 minutes, then flip over and sear on the other side for 2-3 minutes. Sprinkle onion soup mix over the meat, add potatoes and broth. 
  • Cover, make sure vent is set to sealed position, and set to PRESSURE COOK or MANUAL for 60 minutes. Do a natural release for 15-20 minutes (don’t do anything, just let it naturally depressurize) then quick release (turn valve to VENT) and remove lid once float valve drops down. 
  • Transfer beef to a serving platter and shred with two forks. Use a strainer to remove any fat or large bits from the liquid in the pressure cooker. Set to SOUP setting and move on with the next step. 
  • Transfer potatoes to a large bowl. Add sour cream, salt, pepper, and garlic and hand mash or use an electric hand mixer until creamy and smooth. 
  • By now the liquid in the pot should be boiling. Whisk together cold water and corn starch and stir into the boiling liquid. Season with salt and pepper (taste, add more if needed) and serve over mashed potatoes. 

From Frozen

  • Follow instructions above, but do not cut meat into sections (since it’s frozen and very hard to cut through) and skip the searing step. Pressure cook for 90 minutes. 

Notes

The following is a substitute for one packet of dry onion soup mix:
2 tablespoons dehydrated onion flakes, 2 tablespoons beef bouillon granules, 1 teaspoon onion powder, 1/2 teaspoon dried parsley, 1/4 teaspoon black pepper, 1/8 teaspoon celery seed, 1/8 teaspoon paprika

    Can you also use London broil for the meat? Very scarce where I am and that’s what I have on hand.

    1. Tiffany says:

      My concern for using london broil with this recipe is that it may not be able to shred as well as the other cuts! I haven’t tried it, so I can’t speak for sure. If you give it a try, I would definitely love to hear how it turns out!

  2. Lee T. says:

  5. Jess says:

    Hello! Im very excited to make this recipe, but im just wondering if i Can add vegetables (Carrots, etc.) at the same time as the roast and potatoes or if they will become too mushY…?

    1. Tiffany says:

      They will need to be larger chunks if you do. Or you can add them in the last 10 minutes!

        Easy to follow this recipe, and everything was delicious! I also included my traditional pot roast veggies of baby carrots, wedge cut sweet onions, and whole mushrooms. Easily removed before doing the mashed potatoes and gravy.

        1. Tiffany says:

          Awesome job, Vicki!

  6. Stephanie Acquarulo says:

    Do you think I could double this recipe for the meat?

    1. Tiffany says:

      If you can fit double in the instant pot without over filling! 🙂

      1. jen says:

        HAs anyone doubled? and how did it turn out?

  7. E says:

    Will this work in a 3 quart Instant Pot? Should I adjust amounts or cooking time? Thank you.

    1. Tiffany says:

      It’s possible- you may need a smaller cut of meat!

  8. Michelle says:

    I just realized i never cut the meat up into 4 iNch pieces! Will it still turn out ok or do i need to cook it longeR?

    1. Tiffany says:

      You may end up needing to cook it longer!

  9. Jen says:

    Hi can i substitute for almond flour instead of cornstarch ? Would it work?

    1. Tiffany says:

      Hi Jen! I can’t say for sure- I have never made that substitution and am not familiar enough with almond flour to make the call! I’d love to hear the outcome if you give it a try tho.

    Quick question do you cook on low or high in the pressure cooker?

    My family loved this recipe We also added carrots.

    1. Tiffany says:

      I use high pressure! Happy to hear that you and your family enjoyed this recipe!
