Recipe Ingredients

Main Ingredient:

Meat- Take 2 lb of chuck roast, freeze the meat before cutting. Remove the extra fats of meat.

Other Ingredients:

We are using here beef stock/broth, vegetable or chicken broth will also work but I would suggest you use beef broth to get a great taste!

You can also use sour cream instead of butter but I personally like the taste of roast with butter. We are using here dried onion soup mix, you can easily buy it from any market or departmental store. In spices, you can add or less according to your taste.

Recipe FAQs

Can I use Frozen Meat?

Yes, you can use frozen meat for this Instant Pot Mississippi pot roast recipe. Please note you will need a few more minutes to brown it.

Fresh (not frozen) beef will most likely get a better sear and turn out even more flavorful. If you are using frozen meat, I recommend fully defrosting it in the refrigerator before cooking. Then, dry the roast with paper towels before seasoning to get that desired golden-brown crust.

How Long Can I Keep it in the Fridge?

You can keep the Instant Pot Mississippi Pot Roast in an airtight container for up to 3 days in the refrigerator. It’s so tasty though, I don’t see it lasting that long! We never have leftovers at my house.

How Long Can I Keep it in the Freezer?

Up to 3 months!

This recipe freezes beautifully, making it a perfect make-ahead meal. Try freezing it in individual-sized containers for meal prep.

So What are the secret Ingredients!?

The first secret ingredient is a package of dry onion soup mix! Dry onion soup mix adds a TON of flavor that is perfect for seasoning beef. It’s usually a combination of dehydrated minced onion, beef broth flavor, and a mixture of spices that were made for complimenting beef.

The second secret ingredient is… jarred peppercini! These flavorful pickled peppers add just a hint of spiciness. Plus, using some of the peppercini’s liquid adds a bright burst of acidity to balance out the dish. It’s brilliant, really.

  1. 5 stars
    18 mins was not nearly enough for us. We like our meat to shred easily and I was having a tough time using my bear claws. Just put it back into the Instant pot for another 15 mins to see if that will make it more tender/shreddable. The little piece I tasted was very good!! Hoping the extra time will do it as this was an easy recipe!

  2. I just read the recipe a d had to go to the store and buy the ingredients. It looked so good I wanted to try it right away.

  3. I just made this. When I opened it, the meat didn’t shred. It was still tough. It was 2.25 lbs. I’ve put it back in for 6 mins. What else do you suggest?

    1. Yes, at 18 minutes, the meat will shred somewhat but will stay in larger pieces. If you want the meat to be completely shreddable, you just need to add more time. Maybe try 30 minutes next time for your personal preference.

  4. WOW. So simple yet so delicious. This is definitely a keeper. Everyone loved it. Have a little left over for a sandwich tomorrow. Thanks.

    1. Diced potatoes only take about 3-5 minutes in the Instant Pot. You could add them with 5 minutes remaining, but you will have to wait for the pot to come up to pressure a second time so it will take longer. Or you could cook them separately and serve them on the side.

    2. Yes open it about 5 minutes before it is done then add potatoes then start back up. Be sure to cook only 5 minutes.

  5. I tried this in my new pressure cooker and put it on a hoagie bun and it was delicious! I didn’t have tge pepperoncini so I used banana peppers instead

    1. Me too! If I can get away with it, i will make it 3-4 it's a month! It's a staple meal, in our house
