Make Mississippi pot roast using a pressure cooker
Two different cooking methods depending on how much time you have. Dump and go, sear and cook methods. Each has benefits.

Prepare the Roast
If the roast is too large, cut it into 4-6 pieces.

Sear the Meat
- Preheat the Instant Pot to Sauté. When the display reads "Hot," add 1-2 tablespoons of oil.
- Sear the meat on all sides until golden brown, about 3-4 minutes per side.
- Remove and set aside.

Deglaze the Pot
Drain excess oil, then add stock and scrape up the browned bits from the bottom of the pot.

Pressure Cook
- Return the meat to the pot. Sprinkle with ranch and au jus packets, then add pepperoncini, juice, and butter.
- Close the lid, set the steam release knob to Sealing, and pressure cook on High for 60 minutes.
- Allow a 15-minute natural pressure release, then manually release any remaining pressure.

Remove Meat
- Remove the cooked meat to a clean plate and make the liquid/drippings into gravy.

Make the Gravy
Turn on Sauté mode, whisk in flour, and cook until thickened.

Serve
Serve over mashed potatoes, rice, or thick-cut fries.

Dump and Go Instructions
- Add the roast to the Instant pot (still cut it into chunks if it doesn't fit in one piece).
- Add the rest of the ingredients leaving out the flour.
- Cook on High Pressure for 80 minutes. 15 minute natural release (With a frozen roast increase the cook time to 90 minutes).
- Finish with the gravy making instructions.
Storage Tips for the Beef Roast
Be sure to cool the extra pot roast completely before storing in an air-tight container in the refrigerator. Use up leftovers within 3 days. I reheat in the microwave but reheating on the stovetop is always a good idea.

You can use a frozen piece of meat but I would do the dump and go method. I would also increase the cook time to 90 minutes.

- The meat will easily pull away from the pan when it is properly seared.
- Remove the meat to a clean plate before deglazing the pan.
To Deglaze The Pot:
- after the meat is removed from the pressure cooker, carefully drain out any excess oil. Add the stock to the pot, stirring and scraping the bottom of the pot of the stuck on brown bits. Those bits are full of flavor and will help enhance the sauce.¼ Cup (59 ⅐ ml) stock

To Make the Gravy:
- Turn the Sauté function back on.
- When the liquid is starting to simmer, sprinkle the flour over the drippings in the pan.
- Whisk well until the gravy starts to thicken. Continue to boil for one minute to cook out the starch flavor.
- Then turn off the pot and add the roast back in or serve the gravy on the side.
- Serve with baked potatoes, mashed potatoes or cooked noodles. I would suggest my sous vide potatoes with rosemary.






Robert Dinsmore says
No amount of flour to make the gravy is mentioned??
Sarah Mock says
That is correct, Robert! The au Jus packet and the Hidden Valley Ranch Dressing packets have some thickeners in them.(at least mine did the last time I looked) That is where you are going to find the thickeners for the gravy. ~ Sarah
