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. It was delish! So flavorful and the meat was very tender. Served with toasted Hawaiian rolls.
I made this recipe in a crockpot instead of an instant pot. I used the same ingredients but cooked it seven hours on low. Turned out perfect. My husband said it was the best pot roast he’s ever had. I used leftovers to make pulled beef enchiladas that were also incredible.
Thanks for an awesome recipe!
Awesome this is what I was looking to see! Did you do step 1? I’d love to be able to skip that lol
Two questions:
1) can I use this same recipe as-is in an 8qt IP?
2) is there a way to use pork instead of beef? one of my family members is stomach-sensitive to beef
Thank you!
So I thought I’d be innovative and throw in some veg with the meat ; potatoes, celery and carrots. I spooned out the meat and veg before adding the starch mixture. It was very delicious, served over buttered noodles- the vegetables were pretty mushy..but the taste was definitely there! Next time, I’ll make it as directed, thank you for another great and easy recipe!
10/10. Uh-freaking-mazing. One of our more expensive meals but worth it. We dont like onion soup so we subbed that for a pot roast seasoning packet.
Made this last night- it was AWESOME. And by far- ridiculously easy. Gotta love that combo.
It’s a special night when my picky husband AND my 19 month old are excited about the same meal. Thanks, Chungah!
wonderful pot roast recipe, I would have never guessed pepperoncini, but love them even by themselves good thinking, and a great thing to IP! Thank you!
I am really addicted on your recipes. I follow you everyday, bravo. Thanks a lot!
How can I do this in a crock pot?
I’m wondering the same thing. How can this be done in the slow cooker / crockpot?
Since there are just 2 of us can I reduce all but cook time in half giving us some left overs? Can the left overs be frozen. I would appreciate a capability on your web site to adjust # of servings and it would recalculate the ingredients?
I’ve frozen it after shredded it up. Tastes great! I use the leftovers to make shredded beef enchiladas.
Yummo!! We love Mississippi pot roast. I will have to try this in the IP. Have you tried Miss. pot roast with the ranch seasoning packet instead of the onion mix? So delicious. I will try this version! We love all your recipes!!
I agree on the ranch sesoning, particularly if you don’t want so much dill seasoning. This is the way I have always made it — with ranch rather than dried onion soup. Each to their own.
You can definitely make this in crockpot. I do it all the time. Just throw everything, except for the cornstarch mix, into CP. Cook on low 6-8 hours. I don’t add in cornstarch, but I would imagine it would be added in at the last half hour or so. Delish!
I only have an 8at IP, is the cook time the same?
Thanks!
Sounds delicious!!! What if you don’t have a Instant Pot? How long would this need to cook in a crock pot? Thanks!
Agree. Need a stovetop or crockpot adaption please
Thank you

I love making pot roast with onion soup mix. It’s the best! Your recipe sounds delicious.
Looks so good. I never know how much fat to remove. Do you take out that thick white middle section and leave all else?
Pot roast is comfort food. Leave the fat on, unless there’s a truly humongous chunk somewhere. You can defat the liquid before you thicken it (pour it into a measuring cup and wait a minute, the fat will rise to the top and be easy to pour off). Remember if you thicken the gravy with flour instead of cornstarch, you’ll need some fat!
Sure looks YUMMY! No IP here. Suggestion(s) for making stovetop and/or crockpot?
You can make this in the crockpot on low. Just add the cornstarch slurry towards the end and after you remove the meat to shred (30 minutes or so before finish cooking).
Just a question. Can you substitute boneless, skinless chicken and chicken broth instead of beef?
If you try that, I wouldn’t cook it the same amount of time. Look up some other recipe for the chicken you’re going to use — I think whole boneless chicken breast takes 6 minutes, but that’s off the top of my head. The ranch dressing and pepperoncini should be a good flavor combo for chicken… I’d maybe leave out the onion soup mix or other seasonings above. Yes for using chicken broth for your liquid.
