reasons to make instant pot mississippi pot roast
- Half the cook time. With the help of the pressure cooker, the cook time is significantly cut down, locking in moisture and flavor.
- Perfectly cooked meat. The meat is cooked so perfectly, melt-in-your-mouth tender, literally falling apart with the most heavenly gravy – slightly spicy, tangy and savory.
- Low-carb meal. Serve with cauliflower rice and an assortment of veggies.
what is Mississippi pot roast
Mississippi pot roast is a type of beef roast typically made with dry onion soup mix and pepperoncini, resulting in a tangy taste with a little bit of heat. The meat is shredded and served over mashed potatoes or egg noodles.

tips and tricks for success
- Sear the meat. Browning the beef first is key here. That dark crust on the chuck roast will create such richer, deeper flavors (plus, the browned bits at the bottom of the Instant Pot are all lovely bits here, adding so much flavor).
- Serve with crusty bread. Serve with all the homemade crusty bread for dipping, sopping and dunking!
- Freeze as needed. Mississippi pot roast freezes very well. Let cool completely; portion into plastic freezer bags in individual servings with the cooking juices. Reheat in the oven at 350°F, covered in aluminum foil (to retain moisture) until warmed through, adding a splash of beef broth to prevent dryness.

Made this tonight and it was amazing! Followed the recipe as stated with no modifications. Great flavor profile, not heavy and super tasty. A must in the meal rotation!
This is now my favourite. Dish. Spicy and delicious
Ohhhh my gosh. This was freaking good. The most tender, flavorful chuck roast I have ever made. At first I was skeptical about the peppers, but they give it so much flavorful. So impressed with this recipe, will be sharing with friends and fam 🙂 thank you.
I have made other versions of this recipe, but this one was the best by far. The whole family loved it – even the picky eater!
Should I use dill weed or dill seed?
The only pepperoncini I can find are the jarred pickled ones. Does the recipe call for pickled pepperoncini? I would love to try this but don’t want to make any assumptions and risk ruining a great meal!
Yes the jars picked ones are the correct ingredient for this recipe
I have the ninja foodi…same pressure time ?
Loved this dish!!! What a fabulous recipe and doesn’t use butter like the slow cooker versions.
A must 1-2 times per month! The pepperoncini pepper add the most interesting flavor to a dish we have been serving for years…
We love the new twist!
Wow! Where has this been all my life?? This was so so so good! My extremely picky 6 year-old even ate some. And I am not ashamed to say that I was just slurping up the sauce by the spoonful! This will definitely be put into regular rotation!
Made it tonight and it was SO GOOD! Sometimes I shy away from pot roast, because it’s a little bland for the amount of work that goes into it. But this was PACKED with flavor, a little heat, and lots of moisture! Will be a “go-to…” thanks for a new fan favorite!!
Does anybody have recommendations on whether or not I should reduce cook time if I use a smaller amount of chuck roast? Didn’t want to make the full amount for just the two of us the first time around! Thank you!
i was wondering the same thing.
I would say no. I used a 2.5 pound roast (the biggest I could find) and didn’t reduce the cooking time. It came out perfect.
This is really a flavorful, unique treatment for pot roast. I have very finicky family members who normally don’t like something a little different…but I screwed up my courage and tried this on them anyway and they raved about it. Now this is how I have to make pot roast with them. I really like the tangy flavor from the pepperoni and the dry herb mixture. The crusty bread suggestion is on point and I usually also throw some small potatoes, carrots, green beans and shallots In olive oil in a foil wrapped grill basket and have an amazing weekend feast. This is a great take on pot roast, really cool flavor profile, one of the very best I’ve come across.
Pepperoncini is apparently a word not liked by iPads…not pepperoni…pepperoncini
LOL
I made this recipe exactly as written and loved it. I spent some time trimming the fat off the beef but other than that it came together quickly. We served it on toasted rolls and got a couple of meals out of it. This is a keeper for me. I did not find the dill overwhelming at all but that is just my taste. Great recipe!
Yum yum yum. Followed exactly and turned out perfect. I served with baby potatoes and a dollop of sour cream. The combo of these flavors is reallllllly good. Don’t sleep on this recipe, friends.
Hello! Could we do this has a slow cooked meal instead? I love your recipes and your cute puppies
I was wondering the same thing.
This was truly one of the most flavorful things I’ve ever eaten. Followed the directions exactly as written and it came out perfectly! Will add this to my regular rotation!
I love 99.9 percent of DD recipes, but this one missed the mark. The quantity of dried dill seriously overpowered the dish. I think that if the dill was reduced by half, this roast would be excellent (and I love dill a lot).
Otherwise, cooking times were spot on, texture was what I expect from a Mississippi roast. I made this exactly as written, and other than the dill problem, I would try it again with modifications.
Really good! I chopped up some more pepperoncinis and added them on top for serving. Will make again!
The Best ever. This has to be one of the best pot roast I have ever made. The meat was tender and extremely flavorful. Make sure you buy the right cut of meat.
I made this last night!!! Amazing! So yummmy
The only change I made…. I seared my roast in my cast …..because well… I just get the sear I like in my Enameled cast better than IP
I deglazed w the beef broth in my cast THEN Put it all in my IP
Yuuuummmm
Try it
This looks so good! Thank you for the nice recipe!
