Instant Pot Mississippi Pot Roast

Man, I must be on a pot roast kick. Just last week I posted my Oven Braised Balsamic Pot Roast, and now I have this Instant Pot Mississippi Pot Roast. One might be thinking pot roast is pot roast, why all the recipes?

Well, while the oven braised balsamic pot roast would be perfect for a Sunday afternoon when you’re home all afternoon, this Mississippi Pot Roast in the Instant Pot is exactly what you need when you don’t have all day to babysit your pot roast in the oven.

What Is Mississippi Pot Roast?

You also might be wondering, what the heck is Mississippi Pot Roast? It is a combination of a chuck roast, pepperoncini peppers, au jus gravy seasoning, ranch seasoning, and butter. It is just as delicious as it sounds!

How to Make Instant Pot Mississippi Pot Roast

To make Mississippi Pot Roast in the Instant Pot, it is very simple. First, you’ll cut a chuck roast into 1 lb chunks. This helps the meat cook a bit faster. Next, the chunks of meat are browned in olive oil, on the Instant Pot’s saute function. This really helps give the meat great flavor – I wouldn’t skip this step!

Next, you will whisk together beef broth, au jus gravy mix, and ranch seasoning, and then pour it over the chunks of browned chuck roast in the Instant Pot. Lastly, add pepperoncini peppers and butter, and seal the lid.

This pot roast in the Instant Pot is cooked for 60 minutes, with 10 minutes of natural pressure release, and you’ll end up with fork tender, crazy delicious pot roast!

We served our Instant Pot Mississippi Pot Roast with blue cheese smashed potatoes, salad, and bread. It would also be delicious on top of mashed potatoes or in a sandwich.
