Instant Pot Pot Roast makes having a tender and juicy roast so easy!  Mashed potatoes, carrots, and a mouthwatering gravy are made in the very same pot!

instant pot roast on plate with mashed potatoes and carrots

Pot roast is such a classic meal alongside carrots and potatoes.  I remember having roast almost every Sunday after church when I was growing up.  Pretty sure I looked forward to it all week!  We love the instant pot version because I can have a super melt in your mouth roast with tender carrots AND mashed potatoes with gravy in about 90 minutes.  Don’t be intimidated by the length of time, this is simple to make, and most of the time is actually hands off.  If you are new here and looking for some more Instant Pot Recipes be sure to try my Instant Pot Mac and Cheese and Instant Pot Beef Stew!

Instant Pot Pot Roast:

  1. You will want a 3 pound chuck roast for this recipe.  Take your roast out of the package, place it on a large cutting board and season it very well.
  2. Heat your oil up in the instant pot while you season your beef. Sear the beef on all sides.  This step is optional, however, you will have much better all around flavor if you sear your meat.
  3. Remove the roast to a plate.  Pour about 1/4 cup of your beef broth into the bottom of the pot to deglaze.  This step is important so that you don’t end up with the “burn” notice.

4.  For best results use a wooden spoon to deglaze the pot.  This step only takes a minute.  You will notice how all those delicious and flavorful brown bits are no longer stuck to the pot.

5. Once you have deglazed.  Add your roast back to the pot.  Add the remaining broth then cover the Instant Pot and set the valve to seal.  Now, cook on manual for 50 minutes.

6.  When the timer goes off, do a quick pressure release.  Add the sliced potatoes and baby carrots to the pot.  Place the lid back on the pot and set the timer to manual for 5 minutes.  This time, allow the pot to natural pressure release.

After you have naturally released the pressure.  Remove the roast and the carrots (using a slotted spoon) to a plate, and cover with foil to keep warm.  Use the slotted spoon to remove the potatoes to a large bowl and mash as directed below.  Cover the potatoes to keep them warm.  Turn the instant pot to saute and add your cornstarch and water mixture while whisking constantly until gravy thickens.

    SO good! Restaurant quality! Level of seasonings were right on, cook time was perfect. I did double the cornstarch/water mixture for the gravy, but that was the only adjustment needed. My family loved it, even my picky eater! This will definitely be added to our regular cycle of meals.

    The best instant pot pot roast I’ve tried! This one has stuck for my family and is a regular in our winter meals rotation! I never thought to put it on mashed potatoes before mentioned here but now I have to have pot roast this way. Thank you!

    As good of pot roast as you will find regardless of method.
    The seasonings are spot on and the ease of the Instant Pot
    Make it a go to recipe. Delicious!

  4. Please inform me on difference between meat/stew and pressure cook ? Does it make a difference ? I have in the past used the pressure cook , but just now realized I read the recipe wrong and it says use the meat setting ? It’s always turned out delicious
    Thank you

  5. This looks delicious, however, I do not have an Instant Pot with pressure so I’ll still try and do it because all the rest of the ingredients are easy to purchase and I’m happy to have received this wonderful looking dinner. Thank you for your creativity! Love,

  6. About how long does it take for the gravy to thicken? It doesn’t seem to thicken for me so I am wondering if I am not patient enough.

    Fantastic recipe. The kids eat it, mom and dad love it. We slice it instead of shredding it now, it still tastes good shredded up. We just seem to get more flavor sliced.

    1. I tried this recipe today and it was a complete flop for me. I do not mean to be critical, I am sure it was a mistake on my part. Someone else mentioned they could not get the gravy to thicken. I had that problem too. I even added an additional tablespoon of cornstarch and water when I realized it was not thickening. There are some glowing reports on this recipe so I am sure it was something I did wrong. I look forward to trying some of your other recipes.

      1. I agree with you. I have to repeat the thickening step several times and even added some ‘better than bullion’ bc I felt the gravy didn’t have much flavor. Potatoes were good though.
