We love Mississippi pot roast in the instant pot, like this Mississippi chicken, but there are so many ways to cook it including a cast-iron dutch oven over the stovetop, air-fryer, and pressure cooker–not only a crock pot! The key to a moist cut of beef is to cook it slowly in the preferred cooking methods.

What is Mississippi Pot Roast?

Mississippi pot roast is basically an American pot roast made with chuck steak, ranch seasoning powder, and pepperoncini peppers. This recipe is made without the sweet Italian chili peppers and is swapped out with jalapeno peppers, making it a spicy Mississippi pot roast. The au jus gravy packet gives this beef dish a light gravy, however, if you want to thicken the gravy, simply stir in a cornstarch slurry during the last hour of slow cooking time made of two tablespoons of cornstarch and two tablespoons of water mixed together.

Is Mississippi Pot Roast Spicy?

The simple combination of chuck roast and jalapeno peppers gives this beef dish a little heat and tenderizes the beef. Once it’s slowly cooked, a lot of the juices render and it just leaves the meat with a zesty and peppery taste. We are not lovers of really spicy foods and this was not too hot for us. For mild Mississippi pot roast simply use pepperoncini peppers or adjust the heat by adding fewer jalapeno slices and more of the pickled brine. Using jalapeno peppers definitely enhance and flavor the meat so this is not your bland beef recipe! (P.S. You will love this aroma as it cooks!)

Mississippi Pot Roast Ingredients:

The ingredients for Mississippi pot roast are so simple! All you need is 5 ingredients and some patience because the key to a moist and tender roast is the slow cooking technique. Here is the list you need:

ingredients for Spicy Mississippi pot roast

  • Beef- chuck roast is well-marbled and tender when cooked. You want a thick cut for braising steak that is not too lean and that has good marbling. Some popular roast choices are Angus beef top round steak, rump roast, and ribeye steak. Lack of fat makes dry roast. I use chuck roast.
  • Dry Ranch Seasoning- is the perfect savory seasoning mix for this beef dish.
  • Au Jus Gravy Packet- is a dry gravy mix that makes a light gravy as the juices cook. If you prefer thicker gravy make a cornstarch slurry towards the last hour of cooking.
  • Butter- I use a stick (4 oz) of unsalted butter that I place over the seasonings right on top of the roast. It ends up melting into the meat as it slowly cooks making it so succulent!
  • Pickled Jalapeno Slices- come in a glass jar with vinegary brine. I use Mt. Olive Jalapeno Slices and also make my own pickled jalapenos. You can use diced or whole pickled jalapenos just keep in mind that diced will be more compact when measuring so, use more brine so it’s not overwhelmingly hot. You’ll want 1.5 cups of both the brine and slices just adjust to desired heat (add more slices for spicy or more brine for mild heat.)

How To Make Mississippi Pot Roast:

The best Mississippi pot roast is slowly cooked for super-tender meat. Braising maintains the moisture and the liquids help it stay that way. Simply put the crock pot on high if you are in a rush to get dinner served within 4 hours, (it will still be a moderately low cooking temperature of 300°F.) If the time allows it’s best to set the slow cooker over low for 7-8 hours.

  1. Wash and pat dry the chuck roast. Place on the bottom of the slow cooker (any brand of a slow cooker, will work.)
  2. Sprinkle with the ranch seasoning mix and the au jus gravy packet.
  3. Put the butter right on top of the roast.
  4. Pour 1.5 cups of the brine and jalapeno slices of pickled jalapenos (this is almost a 16 oz jar of jalapeno slices.)
  5. Cook the roast slowly. Set the crock pot on high for 4 hours or low for 7-8 hours. The internal meat temperature should be 195°F /90°C for tender beef.
  6. Let meat rest for 5 minutes before pulling it apart or serving.

How Long To Cook Mississippi Pot Roast:

Typically, Mississippi pot roast cook time is 4 hours over high in a slow cooker. If the time allows you can prepare this early in the morning and set it over low for 7-10 hours. Generally, a slow cooker on high is 300 degrees Fahrenheit and the low setting is 200°F. To replicate these cooking temperatures using different cookware, simply cook the beef at the given temperatures or until the internal meat temperature is 195°F for a tender roast. The roast is ready when it falls apart easily.

Variations and Add-ins:

Crockpot Mississippi pot roast can be made in a few different ways. Here are some creative ways to prepare this Mississippi pot roast in a slow cooker with different add-ins.

  • Classic Mississippi pot roast- use a whole 16 oz jar of pepperoncini peppers for the jalapenos and omit the au jus gravy packet.
  • Mississippi pot roast oven- place roast in the oven at 300°F for 3-4 hours. Use a cast-iron dutch or enamel dutch oven pot with an oven-safe lid.
  • Mississippi pot roast with Potatoes and carrots- add a small bag of baby carrots and 1.5 pounds of baby potatoes with the roast.
  • Add your favorite vegetables like broccoli or Brussels sprouts or serve them roasted on the side if you prefer them firmer.
  • Substitute onion soup mix for the au jus gravy packet for a savory flavor. Swap out the beef with pork roast and add liquid smoke for a smoked flavor.

Mississippi Pot Roast Sides:

We love this easy Mississippi pot roast with creamy mashed potatoes! The gravy goes so well with the potato puree but there are so many ways to eat this including some gluten-free options. Here are some of the best ways to serve Mississippi pot roast and our favorite sides!
