Instant Pot Mama’s Pot Roast Recipe

I got an Instant Pot last week and have been cooking with it ever since! One of my favorite slow cooker recipes is with a Roast so I thought my first recipe needed to be Mama’s Pot Roast!

If you have never heard of a Instant Pot – they truly are wonderful! I was a little nervous to try it out because I DO NOT like new things. But my husband surprised me for my birthday so I thought I would try it out. Well, I honestly can say I LOVE IT! Instead of cooking my roast for 8 to 10 hours in the slow cooker, It cooked for 60 minutes and was just as tender!

I also threw in some carrots and potatoes so I could have a side dish done all at one time!

  1. My in-laws gave me an Instant Pot someone had given them and it honestly sat forgotten in a box in my laundry room for ages. Then I kept seeing Instant Pot recipes pop up on my favorite food blogs and I remembered that box. I wasn't even sure that's what I had, but praise be, it was! I love it! I'm so excited to try this (and the Instant Pot cheesecake recipe I found today!) and am looking forward to your upcoming Instant Pot recipes!!!
    • Here is some information I found for you on Instant Pots - On older Instant Pots, the “Manual” button means pressure cooking. On newer pots, there is an actual “Pressure Cook” button. (Hooray!) The default for both of those buttons is High Pressure. Press the manual or pressure cook button, use the plus and minus buttons to adjust the cooking time, then leave the cooker alone for ten seconds and it will beep and start cooking. (Hit cancel if you need to change something.)
    • With a roast that small it's not going to take very long. Maybe 15 minutes. You should have received a cooking booklet with your instant pot that will help you determine the cooking time on different sizes of meat. This website might be helpful too.
  2. I’m going to use this recipe for dinner tomorrow; however, I want to use your recipe for twice baked potatoe casserole as well. Therefore, I’m going to leave out the potatoes in this recipe. How should I alter the ingredients if I leave the potatoes out? Thanks in advance!

    Made the roast today. 2.9 lb roast. Seared, dumped as instructed. The only thing is about 60 minutes or so would have been good. However even at 80 mins it saw like my mom liked it and meat was so tender, veggies a little soft. It was awesome. My first pot roast in IP but won't be my last. I did add a can of drained Rotel tomatoes. SOOOOOO good. Thanks
  4. Daddy (that's me) made Momma's Pot Roast in our newish InstaPot for dinner with Momma. Didn't have the potatoes, but put in lots of green beans. Had only chicken broth, so... what the heck. Followed all other instructions and WaaLaa! It turned out great! This is a pretty can't miss dish. Thanks lots!
