What Is Mississippi Pot Roast?
Mississippi pot roast is a popular variation on traditional pot roast. It’s typically made with chuck roast, lots of butter, gravy mix, ranch seasoning, and pepperoncini peppers. The peppers give it a mild, slightly tangy flavor that’s unique to the recipe.
This version includes a few extra ingredients, like onion and carrot, to turn it into a complete meal when served over potatoes.
Ingredients Needed
Ingredients like Montreal seasoning, pepperoncini, au jus gravy mix, and ranch dressing mix give this slow cooker Mississippi Pot Roast its incredible flavor.
(Scroll below to the printable recipe card for details and measurements.)
- Montreal seasoning – This seasoning blend, made with spices like salt, red and black pepper, garlic, and onion, is one of my secret ingredients for elevating a simple Mississippi pot roast recipe.
- Chuck roast – Chuck roast is the most common cut of meat for pot roast, due to its marbled texture, but beef bottom round roast or beef rump roast will also work here.
- Olive oil – Used to get a golden sear on the roast and also necessary moisture.
- Butter – I use Kerrygold Garlic & Herb butter for a huge flavor boost.
- Onion & Carrot – These add more flavor, texture, and substance to the recipe.
- Garlic – For aromatics and flavor.
- Pepperoncini – The star ingredient of any Mississippi pot roast recipe. While you’ll want to grab a 12-ounce jar, you’ll actually need just 8 peppers and some juice.
- Seasoning and gravy mixes – Using au jus gravy mix, onion soup mix, and ranch dressing mix adds incredible depth to the flavor of this pot roast.
- Beef stock – The liquid needed for the roast to cook in.
- Salt & pepper

- Sear the roast. Rub the Montreal seasoning over the roast then sear in olive oil until golden brown – about 2 minutes per side. Place in the crockpot.
- Make the broth mixture. Melt the butter in the skillet then add the onion, carrots, garlic, pepperoncini and juice, the seasoning packets, and beef stock. Stir and simmer for 5 minutes.

Tips for Success
Here are a few tips for making this slow cooker Mississippi pot roast.
- Do I have to sear the roast first? While you could skip this step, I don’t recommend it. Searing the roast takes just a few minutes and it adds SO much flavor.
- Cook low and slow. This is not one of those slow cooker recipes where you can increase the temperature and reduce the cook time. Chuck roast needs to cook on low for an extended period of time to properly break down and become tender. If you reduce the cook time, you’ll just end up with tough meat.
- Do not open the lid while the roast cooks. As tempting as it is, keep the lid on until it’s time to ensure the roast is fully cooked. You want to keep all the temperature and steam in the crockpot and there’s no need to stir it.

Serving Suggestions

For next level comfort, serve it over mashed potatoes. Since it’s cooked with onions and carrots, another side isn’t needed but if desired, you can also enjoy it with some roasted broccoli or roasted cauliflower. You could also serve it with rice.
Another option is to serve it up on hoagie rolls, with or without French fries. Basically, you just want to make sure to serve it with something that will soak up every last bit of the gravy!
How to Store & Reheat Leftovers
- Fridge. You can store leftover slow cooker Mississippi pot roast in an airtight container in the fridge for up to 4 days.
- Freezer. This also makes a great freezer meal. Just allow it to cool completely, transfer to a ziploc freezer bag, and freeze for up to 3 months. Thaw overnight in the fridge.

This was easy and delicious. A little spicy for my 10-year-old. I’ll cut back a bit on the pepperocini juice next time.
This pot roast is delicious and is an easy way to feed a crowd! It has a little bit of heat and the right balance of flavors.
My husband and I really liked this recipe….And so EASY!
Will definitely cook this again.
Wow! Was this delicious! Only way I will make pot roast from now on. I can’t believe at the age of 66, I never had this before!
Absolutely scrumptious!
I’ve tried several variations of the Mississippi roast and this one was BY FAR superior!!! Such great flavor and the meat was very tender. I added a whole bag of baby carrots and it was perfect. Served with mashed potatoes and Texas toast.
This was a big hit with my family.
So easy, it’s hard to believe it’s phenomenal taste! The only issue is the gravy was too salty, likely because of the 3 seasoning packets. Next time, I will omit the salt and cut the amount of seasoning packets by half.
Best potroast ever!
I added potatoes, only change I made. This was excellent!! So much depth of flavor and the meat was incredibly tender. Already looking forward to leftovers today for lunch.
Outstanding!
