Easy Mississippi Roast (Pepperoncini Roast)

I can’t even begin to tell you how many times I’ve made this recipe since my niece, Katherine, shared it with me a while back. One day she told me about one of her favorite slow cooker recipes that she makes all the time.

And with just one bite, I was hooked and have been making it ever since! That Kat is a smart, smart young woman!

Traditional Mississippi Roast includes using seasoning and gravy packets. Since I prefer to not use those and keep my recipes as simple as can be, I decided to remake that version into this 3-ingredient wonder! I’ve included the optional ingredients you would need for the more traditional recipe if you’d like.

Now, making this slow cooker roast recipe really couldn’t get much simpler!

Ingredients You’ll Need for this Recipe

  • Roast – I like to use a chuck roast that is about 3 pounds in weight.
  • Stone House Seasoning – You’ll need a tablespoon of my homemade seasoning that I call Stone House Seasoning. If you already have it on hand, great! If not, use 1 1/2 teaspoons kosher salt, 1 teaspoon of ground black pepper, and 1/2 teaspoon granulated garlic or 1/4 teaspoon garlic powder.
  • Pepperoncini Peppers – You will use a whole (25.5-ounce) jar of pepperoncini peppers along with their juices.

You just toss in your roast, sprinkle on your Stone House Seasoning, and then pour in a whole jar of pepperoncini peppers, along with their juices. Finally, put the top on your slow cooker, set the timer and walk away!

That’s it.

Classic Mississippi Roast Recipe

To make this recipe closer to the classic Mississippi Roast recipe, you will add two more ingredients.

Ranch Seasoning – the original recipe that was shared with me included using a packet of ranch seasoning mix. I use my own homemade ranch seasoning in place of it.

Cornstarch – again, the original recipe included using a packet of gravy mix. In place of the gravy packet, I use cornstarch to make a slurry to add back to the roast to form a quick gravy. To do this, simply ladle about 1/2 cup of the juices from the slow cooker once the roast has cooked through. Pour the juices into a small bowl. Add 1 tablespoon of cornstarch to the juices and whisk together until smooth and combined.

Once cooked through, shred the beef with two forks and serve.

It is delicious served with mashed potatoes and vegetables or in sandwiches with provolone cheese, layer on the beef (and a little bit of the juices) and serve warm. If you want your cheese fully melted and scrumptious, pop back into the oven for about 3 to 5 minutes or into the microwave for about 30 seconds.

  1. I’ve made this before in my InstaPot, cooking for about 50 minutes, then adding carrots and onions for 20 more minutes. Also, added a package of dry ranch dressing. It’s delish!

  2. There’s a very similar recipe that’s my go-to, especially when my family is craving comfort food. It’s called Mississippi Pot Roast. Instead of Stone House Seasoning, it calls for a packet of ranch dressing mix and a packet of au jus mix. Throw in the pepperoncini and top with 1 stick of butter. Set slow cooker on low for 8 hours. Everyone who tastes it asks for the recipe, but only after dinner is over. All you’re likely to hear during dinner is your guests making yummy sounds. Simply amazing.

  3. This was a super easy recipe with a surprising amount of flavor. I don’t even like pepperoncini peppers but it gave the meat a great flavor. I’d definitely make it again. I served it on sub rolls with provolone cheese as suggested; delicious!

  4. I too was doubtful, yet made the recipe. I used a traditional top-of-the-stove cooking method. It was wonderful! Definitely a keeper!
