Ultimate Crockpot Mississippi Roast is amazingly juicy and fork-tender! It takes only 10 minutes of prep in the morning and the roast is then simmered in a rich and divine sauce all day in the slow cooker. Add some vegetables to the crockpot and you’ll have a perfect weeknight meal with a delicious built-in gravy.
This Mississippi pot roast is one of the easiest recipes for busy days. You literally only need to spend 10 minutes or less to dump everything in the slow cooker in the morning and you’ll come home with a warm, hearty, and melt-in-your mouth delicious comfort food.
The best part is that the whole meal can be made in one place. It consists of chuck roast (bone-in or boneless) cooked slowly in a crock pot with ranch dressing mix, au jus gravy mix, butter and a few pepperoncini peppers. You can add vegetables such as potatoes, carrots, onions, or your favorite ones to make it a complete meal. They will soak up all that tasty flavor!
Once the Mississippi roast is fully cooked, remove to a serving platter and shred with two forks. To make the sauce into a thick gravy, simply add cornstarch and water mixture to the sauce in a saucepan. It will thicken into a delicious Mississippi roast gravy in a few minutes. You can drizzle it over your pot roast, mashed potatoes and veggies!
Tips for the best slow cooker Mississippi roast:
- No need to brown the beef before putting it in the crockpot. I have tested both ways and searing it first doesn’t make much difference.
- You don’t need to add any liquid as the slow cooker traps steam generated from cooking, keeping the roast moist.
- To have a thicker gravy, simply add cornstarch slurry (mixture of 1 tablespoon cornstarch and 2 tablespoons of water) to the juices and cook them in a saucepan for a few minutes.
- If you’d like to cook the roast with potatoes, Yukon gold and russet potatoes are good choices.
Special ingredients and tools
The roast: It’s best to use tough cuts such as chuck roast, which comes from the shoulder and has great flavor. Other cuts that are good for this recipe include bottom round roast, Brisket, shoulder steak and tri-tip.
Pepperoncini: The original Mississippi roast recipe calls for pepperoncini as a key ingredient, and it delivers just a touch of heat. You can definitely pass it on and use other pickle options such as pickled jalapeños, carrots or dilly beans.
Slow cooker: I used a 6-quart slow cooker, which works great with a 4-pound roast.

This is the most awesome recipe in the world. I was surprised at how good the peppers tasted. So, next time, I plan to add more peppers. This really have a wonderful flavor that you would not expect from such a simple dish.

Best pot roast I have ever had. and so easy. I never want it any other way ever again. Thanks for posting this recipe. We had it Valentine’s night.
Are you supposed to make the au jus and ranch mix according to package directions first or just add the dry powders? There’s no mention of adding any water or broth just the butter and mixes – is that correct?
Hi Ken, simply add the mix directly to the crockpot.
Yes, just put the dry mixes in it and DO NOT add water or broth.
I also like to add a packet of the dry beef gravy.
