Instant Pot Mississippi Pot Roast
I'm going to fully admit here, I kept hearing stories about Mississippi pot roast being the "best ever" roast recipe and I've been pretty skeptical since the entire recipe seemed like an odd assortment of ingredients.
Yet, pot roast makes for a quick and easy dinner that the whole family enjoys - especially Instant Pot roast, so off I went to see what all the fuss was about (all the while questioning pepperoncini peppers in a pot roast? Could pepperoncini pot roast really be the BEST EVER pressure cooker pot roast recipe?).
After researching the original recipe and tweaking it just slightly (and adapting for my pressure cooker!), we were certainly surprised at how much we loved this Mississippi roast! And instant pot Mississippi roast actually IS the best pot roast recipe. Who knew??
To keep your Instant Pot Mississippi roast in true southern form, you are going to want to serve it alongside some tasty grits. However, there are other sides that go just a well including cheesy low-carb cauliflower casserole, mashed potatoes, and oven-roasted broccoli.

Ingredient Notes
Your Instant Pot Mississippi roast may be full of BIG flavor, but your ingredient list is small with just 5 items needed.
- chuck roast, boneless
- olive oil
- beef broth
- pepperoncini liquid
- ranch dressing (or homemade Ranch mix)
- au just gravy (or homemade au jus mix)
- butter
- Whole pepperoncini peppers - 2 per person is recommended
Ingredient Notes: I try as much as possible to avoid packaged mixes due to food allergies/sensitivities in our family. If this is you too Simply Organic carries a packaged Ranch dressing mix that was a great substitute for the popular Hidden Valley ranch dressing.
I've also linked recipes from other bloggers if you'd rather make a homemade Ranch mix or homemade au just mix.
Equipment
A Pressure Cooker - This is the Instant Pot model that we used.
Step by Step Instructions
Prep
Turn the instant pot to sauté and wait until the instant pot is hot (and you get the "hot" signal letting you know your pot is fully heated).
Add the olive oil and sear the chuck roast on high on each side until brown, which will take 2-3 minutes per side.
Remove the roast and set aside. Add the beef broth and scrape up the little bits on the bottom of the pot. The reason you want to remove the roast and scape up the meat bits is to avoid getting the burn signal during cooking.
Assemble
Add the chuck roast back to your instant pot and sprinkle with the ranch mix, au jus mix and pepperoncini liquid.
Cut the butter into 4 pats and lay on the top of the roast. Many recipes call for up to 1 full stick of butter for this recipe, so feel free to add more if you prefer. We personally found that this recipe had tons of flavor by just using a ยฝ stick of butter.
Add the whole pepperoncinis to the pot as well.
Pressure Cook
Put the lid on the instant pot and set it to Pressure Cook for 75 minutes (1 hour 15 minutes). Depending on the size of your roast, it could take a little bit longer. The roast I used was 2.75 pounds.
Let the roast fully natural release, which took my roast 25 minutes.
The beef should be easy to shred and be falling apart when you check it. So if this isn’t how your roast is, put the roast back in and add 5 mins more to the cooking time.
Simply shred the roast right in the pot and be sure to serve with a side dish that helps soak up that incredible sauce!
This instant pot Mississippi roast is terrific served with mashed potatoes, grits, rice, cauliflower rice, roasted vegetables, or just as is!
Recipe Tips
- You can skip searing the meat step to make this a "dump and start" recipe if you prefer or don't have time to sear.
- Depending on the size of your roast, it could take a little bit longer than 75 minutes to cook. The roast used in the recipe was 2.75 lb. If you open up the Instant Pot and the meat isn't easy to shred, put the lid back on the pot and pressure cook it for 5 more minutes.
- To bring the sodium content down in the recipe, use unsalted butter instead of salted.
- The original Mississippi pot roast recipe uses an entire cube of butter, our version cuts this down to ยผ cup of butter (ยฝ cube), but it can be omitted entirely if preferred.
- Add vegetables like potatoes and carrots for variety, the cooking time will still be the same.

Has anyone else used a PowerCooket XL brand pressure cooker for this? The timer would not let me cook for 60 minutes. Had to select Stew option for maximum of 50 minutes.
RESA DAY says
Hubby and I found this recipe on Facebook years ago. We add more veggies to it to fill the crock pot up to the rim.
We add the regular onion, potatoes & carrots. But then we add Allen's green beans & short cut ears of corn.
We cook ours in the crockpot 6 to 8 hours and it is 100% always falling apart. I shave the corn off of the cob before adding it to my bowl. The corn was a surprising addition!!! It is such a sweet contrast with the roast.

I bet it's even better with lots of veggies added like you're doing! Adding fresh corn sounds amazing, thank you for sharing the tips!

KB says
I've made this twice now, and while I really like the flavor, the roast has come out very tough and dry both times. Am I cooking it too long? Too little? Please help--I really want to perfect this recipe!
WholeLottaYum says
If the roast is still dry you'll want to cook it longer! If it isn't falling apart it isn't done yet.
Ana says
The instructions with the pictures say to cook for 60 minutes, but the ones at the bottom say 75. Which one is correct?
Dee Hawthorne says
I made this for the first time last night, my husband loved it. I will be making this more often?
Billie says
Your instructions says to use whole pepperoncini peppers (5-8). Then later it says use the pepperoni juice and never says when to add the peppers.
I'm singing it, but would like to know the correct instructions please. Can you help?
Billie says
*winging it
WholeLottaYum says
Hi Billie! Sorry about that if it wasn't clear. The pepperoncini's get added at the beginning when the roast gets added. I'll update the recipe to make it more clear! Enjoy! It's one of our favorites!
