Instant Pot Mississippi Pot Roast

I am so happy to share this Mississippi Pot Roast recipe. It is one of my family’s favorite pot roast recipes.
Being able to use my Instant Pot on slow cook or my crock pot makes this a great make ahead meal that is a hit with the family any time that I make it.

How I Make Mississippi Pot Roast to be Trim & Healthy

I’ve always made Mississippi Pot Roast in my Crock Pot but I really wanted to try it using the slow cook function on my 6qt Instant Pot Duo60. So that’s what I set out to do.

The original recipe that I used had a bunch of seasoning packets that contained off plan ingredients for my Trim Healthy Mama journey.

Homemade Ranch Seasoning Packets (THM NSI, Low Carb, Low Fat)Because they were off plan I replaced that store bought ranch packet with one of my own Homemade Ranch Seasoning Packets

How to replace the au ju packet was another stumbling block, but hey we have to think outside the package sometimes. 

So I used some coffee that was leftover as well as a bit of water for the win.

Potato Replacements

Since beginning my journey I have replaced potatoes with a variety of non starchy vegetables. Things like radishes, kohlrabi and turnips. Rick prefers when I use turnips in our pot roast so that is what i used in this recipe although any of these options will work.

One thing about using a Crock Pot or your Instant Pot you need to make sure that your vegetables are all about the same size so that everything cooks evenly. As you can see from the photos I did add carrots to this, just remember that you can have a few carrots in a meal like this Mississippi Pot Roast. 

Beef Roast in the Instant Pot

Different cuts of beef will cook differently in your instant pot but not so differently in your crockpot. I belong to a couple of Facebook Groups that focus on cooking in your Instant Pot. Most of them do not recommend cooking “rump roast” under pressure because it needs the low and slow cooking times of a slow cooker or crock pot to become tender. I purposely purchased a “rump roast (bottom round) for this recipe because I was testing the slow cook function on my Instant Pot Duo60.

I’ve seen many many fails with “rump roast” under pressure so I leave that to cuts like chuck or sirloin like my friend Carey from The Healthy Milestone uses in this recipe.

So mama remember “low and slow” for those “rump roasts”!!

  1. Why is the instant pot time longer than the crockpot time? I am new to Instant Pot, but I thought it was supposed to be faster than the Crockpot.

    1. I used the slow cook function on the IP and it heats differently than a traditional crockpot. I was also being cautious t make sure that it was all the way done.

  2. If I cooked this on the Pressure Cooker setting instead of slow cooker, what time would you give it at high pressure?
