How to Make Instant Pot Mississippi Pot Roast

STEP ONE: Prepare the Roast

Season the beef chuck roast with salt and pepper. Set your Instant Pot to 'Sauté' mode and add olive oil. Once hot, sear the roast on all sides until browned, about 4-5 minutes per side. Remove and set aside

STEP TWO: Deglaze the Pot

Pour the beef broth into the Instant Pot, scraping the bottom to release any browned bits. This step adds extra flavor to your pot roast.

STEP THREE: Add Ingredients

Place the roast back into the Instant Pot. Add the pepperoncini peppers, their juice, au jus mix, ranch seasoning, and the stick of butter on top of the roast.

STEP FOUR: Pressure Cook

Close the lid and set the Instant Pot to 'Pressure Cook' (Manual) on high for 60-80 minutes (20 minutes per pound). Allow a natural release for 15 minutes, then quick release any remaining pressure.

Carefully remove the roast, shred it with two forks, and mix it back into the juices before serving.

Storage

Store any leftover Mississippi Pot Roast in an airtight container in the refrigerator for up to 3 days. To freeze, store the cooked and cooled pot roast in an airtight container or freezer bag for up to 3 months, then reheat gently when ready to serve.
