Mississippi Pot Roast Instant Pot Recipe

I know you have probably found all over Pinterest several Mississippi Pot roast recipes. I even have a delicious Mississippi Pot Roast Recipe for the crock pot.

However, I often put it off and forgot to throw it in the crock pot. One day,  I decided to turn it into a Mississippi Pot Roast Instant recipe. The roast is so tender that it tastes slow cooked.

You really are going to love this instant pot recipe. Roast is the perfect comfort food, you may also love 3 Packet Roast, Crock Pot Chuck Roast Recipe or Crock Pot Dill Pickle Pot Roast.

Why We Love This Recipe

How could a pressure cooker make a roast so quickly and taste like it had been cooking all day? I don’t quite understand how it does it, but it does work.

This roast came out super tender and taste like it had been cooking all day. This would be perfect to throw in before you go to church or when your morning is too busy.

Pressure cooking makes it so tasty but you will think the meat was slow cooked all day. It is seriously that tender. You will love having this easy recipe on hand for quick meals.

Ingredients

How to Make Instant Pot Mississippi Roast

Step 3 – Place the stick of butter on top and pour the Pepperoncini Peppers over it. Pour water around the roast.

Expert Tips

• Instant Pot Recommendations – I am using an 8 quart Instant pot but you can use a 6 quart. I personally have an Instant Pot and so far I am loving it. If you have been putting off trying an instant pot, I highly recommend going ahead and biting the bullet. I love using the pressure cooker when I don’t have much time.
• To Reduce the Salt. – Make sure that you use unsalted butter and do not add any broth. I only use water in this recipe to reduce the salt. You can also use half of the pepperoncinis in this recipe to reduce the salt as well.
• Use whole Pepperoncinis. – They sell whole and sliced pepperoncionis. I use whole pepperoncinis so that anyone that doesn’t like them can easily pick them out. Also, the whole works best with the long cook time that is needed to make the beef tender in this recipe.
• Use a marble roast. I love using a well marbled roast in this recipe so that it adds more flavor to this

How to Make the Pot Roast Gravy

• Remove the beef and peppers from the instant pot and switch the instant pot to the sauté setting.
• Then mix 2 tablespoons of cornstarch (or flour) with 1 cup of cold water. Whisk together until blended completely.
• Whisk this mixture into the juices in the instant pot. Then cook for 2-3 minutes until the sauce has thickened.
• Taste test it and seasoning with salt and pepper. Then it’s ready to serve with the Mississippi roast.

Can You Use a Frozen Roast?

Yes, you can use a frozen roast for this recipe. It will take longer to make in the instant pot but it’s still quicker than cooking in a slow cooker or the oven.

If you use a frozen roast, add 10-15 minutes to the pressure cook time for this recipe.
