This slow-cooked Mississippi pot roast with carrots and potatoes has some unexpected ingredients, including pickled jalapeno peppers and their juice. It is thickened with brown gravy and buttermilk dressing. Try this unusual combination of ingredients for a great pot roast!
One-Pot Slow-Cooked Mississippi Pot Roast
This pot roast recipe was first made by a home cook in Mississippi. Afterward, another cook tried it and placed the recipe in a church cookbook. From there, it spread outside Mississippi, and bloggers started publishing it. One blogger called it Mississippi Roast, and the name stuck! It uses an unusual combination of ingredients that might have you questioning how well they work together. Do not worry because this is a delicious main dish good enough to serve guests.

Slow-Cooked for Convenience
This pot roast is so easy to make. Place the ingredients in a slow cooker and let them cook for several hours until the beef is fork-tender and easily shredded. Cook this dish on high for approximately 7 hours or on low for about 10 hours — whichever suits your schedule. The finished beef should be tender and easily pulled apart. If it is not tender enough, cook it a little longer. Also, remember to adjust the time if you use a different size of roast than what is listed in the recipe.

Peel and Cut up the Vegetables for Mississippi Pot Roast
The vegetables are optional for this pot roast. Add them if you prefer, or prepare the roast without them and serve it with sides such as mashed potatoes. If you do not add vegetables for a one-pot meal, this roast is delicious shredded for making beef sliders or tacos.

Prepare the Roast for Slow Cooking
Season the beef roast with salt and pepper, then place it in a skillet and brown both sides. The browning will caramelize the beef, adding flavor and a nice color. However, there are times when I don’t have time for this step, and I place the beef roast directly into the slow cooker without browning it, and it still turns out just as delicious.



How do Pickled Jalapenos Flavor Mississippi Roast?
The pickled jalapenos and their juice impart a subtle flavor to the roast, giving it a mild pepper taste. The juice contains vinegar (an acid) and will help tenderize the roast as it cooks. I used tamed (less hot) pickled jalapenos; however, you can use hotter jalapenos if you prefer a spicier flavor. Or if you are worried jalapenos could be too spicy, add less than the recipe lists or omit them altogether. However, be sure to add the pickling juice, as it adds flavor and makes the beef extra tender.

Ranch Dressing in Mississippi Pot Roast
Some of the ingredients for this recipe may seem like an odd combination, and you might wonder how well ranch dressing and pickle juice pair together. They are unbelievably delicious! Although the combination might seem questionable, the result is flavorful, melt-in-your-mouth beef. Enjoy!
This roast also comes with a brown gravy that is easy to prepare and adds the best flavor. However, you can substitute a packet of brown gravy for the homemade. Instructions are in the recipe notes.
