Instant Pot Mississippi Pot Roast
It’s been over a year now since I made this pot roast for the first time, as Christmas dinner for the family. We ran out! Luckily there were plenty of other things to eat, but everyone wanted more Instant Pot Mississippi Pot Roast!
I will be making this Instant Pot Mississippi Pot Roast again this year, because the guys loved it so much. This year is going to be a double batch! I hope it’s enough.
Cooking a pot roast in your electric pressure cooker is a great time saver. You get a tender, flavorful pot roast in a little over an hour, versus the 3 to 4 hours it normally takes in the oven. And it tastes just as good! The key to the best flavor, in my opinion, is to brown it at least 5 full minutes on each side before pressure cooking it. You don’t have to, but it adds great flavor, and cuts down on the pressure cooking time. I put my own little spin on it, and added onion, which I think add so much more flavor to the recipe.
Robin Chapman, the original creator of the Mississippi Pot Roast, says that this is great in sandwiches, so that’s what we are going to try next!

- Salt and Pepper, to season the meat
- 3-4 lb Chuck Roast, cut into 1 lb chunks of even thickness
- 3 Tbsp Vegetable Oil
- 1 small Onion, chopped
- 9 Pepperoncinis
- 1/2 cup Pepperoncini Juice from the jar
- 3/4 cup Beef Broth
- 1 Packet of dry Ranch Dressing
- 1 Packet of Au Jus
- 1/2 Stick of Butter
- 3 Tbsp Flour
- 3 Tbsp Softened Butter
Salt & pepper all sides of the meat.
Turn pot on Sauté mode (normal). When the display reads "Hot" add the oil.
When oil heats up, place meat in one layer into the pot and don't move it for 5 full minutes (Don't brown for less than that).
Turn meat over and cook for another 5 full minutes.
Remove the meat to foil or a dish you can cover. Wrap it to keep it warm.
Deglaze the pot: Add onion to pot and stir, add a bit of the beef broth or a small amount of water if there is not enough moisture to loosen the brown bits from the bottom of the pot. Stir, scraping the bottom of the pot until the bottom is free of the stuck on brown bits.
Add the pepperoncinis and their juice, beef broth, au jus and ranch packets, and butter. Stir to combine.
Turn off the sauté mode.
Add the meat back into the pot.
Close lid and set knob to Sealing position.
Set to Pressure Cook/Manual for 55 minutes.
When cooking cycle ends, let it sit and count up to 15 min (15 minute natural pressure release, or NPR).
After the 15 minute NPR, turn off IP, and manually release the remaining pressure until the pin drops, and open the lid to a delicious pot roast!
Remove the pot roast to a plate and cover.
Turn the Sauté function back on.
Mix the flour and butter together until well combined.
When the liquid is starting to simmer, add the mixture to the pot, stirring well until thickened. Then turn off the pot and add the roast back in.
Enjoy with mashed or baked potatoes, or over rice.
