Mississippi Pot Roast Ingredients List

Unlike traditional pot roast, Mississippi Pot Roast has a bit of zesty, tangy flavor thanks to the combination of the ranch dressing mix, brown gravy, and pepperoncini.

For specific amounts, please refer to the printable recipe card at the bottom of the post.

• Chuck Roast (Or Rump Roast) – nicely marbled 
• Dry Ranch Dressing Mix – or two tablespoons of a homemade ranch mix
• Au Jus Gravy Mix or Brown Gravy Mix – either will work beautifully in Mississippi pot roast
• Unsalted Butter*– if you have it. The ranch, au jus, and pickled pepperoncini contain plenty of salt. 
• Pepperoncini Peppers – pickled and jarred, you will use the peppers and some of the juice. They are found in the condiment aisle at the grocery store.

How To Make Super Easy Mississippi Slow Cooker Pot Roast

I’m all about the time-saving factor (and the fantastic flavor, of course) for this savory, tender Mississippi pot roast. That means dump and done! No pre-searing is required! Grab your slow cooker and let’s get started!

When you are cooking, you’ll want to use the full recipe at the bottom of the page.

1. Throw the roast in the slow cooker and dump both seasoning packets, evenly over the roast.
2. Dump the pepperoncini peppers and juice in, then put the stick of butter on top of the pot roast. 
3. Set the slow cooker on low for 7-8 hours or high for 4-6 hours. 
4. Use two forks (or these cool meat claws) to shred your Mississippi slow cooker roast when it’s done. 
5. Serve the amazingly savory, tender roast with gravy and a pepperoncini on the side.

Mississippi Roast Recipe Notes and Tips

DON’T MIX ANYTHING!! This pot roast is an authentic dump-it-and-leave-it slow cooker recipe! (The thicker your Mississippi pot roast, the longer you will need to cook).

• The Roast: A rump roast is usually more tender than a chuck roast. A rump roast is classified as an extra-lean cut of meat, while a chuck roast is just considered lean. Both the chuck and rump roasts are inexpensive cuts of beef. These cuts can produce a tasty, tender Mississippi roast in the slow cooker when cooked on low for a long period of time.
• To Sear or Not to Sear: Some people sear their roast first; I do not. If I’m going to use my slow cooker, why dirty another pan to cook the pot roast before it goes into the slow cooker? If you’d like to take that extra step to sear it first, I’m sure the slow cooker roast will be extra flavorful, although I can’t imagine it tasting any better than it does without searing. 
• The Salt: The first time I made this pot roast recipe several years ago, I seasoned it with salt and pepper. The pepperoncini roast turned out SO salty! As a matter of fact, we disliked it so much I didn’t make it again for two years. The ranch and gravy mixes have a lot of sodium, so there’s no need to add salt! I also recommend unsalted butter and prefer to buy a low-sodium gravy mix if I can find it. Mississippi pot roast now makes an appearance on our table quite often.
• The Butter: I think I have used a whole stick (½ cup) of butter a few times, but most of the time, I only use half of a stick (¼ cup), and we can’t really tell any difference. If I buy a larger roast, I’ll use the whole stick of butter on the pot roast.
• The Peppers: My family is usually not a big fan of spicy peppers or even sweet peppers, so I wasn’t sure how this pepperoncini roast recipe would go over. I’m happy to report everyone gave it a big thumbs up and loves the unexpected flavor and tenderness the pepperoncini add. I usually discard most of the peppers when serving the shredded beef, but I will save a few in case anyone wants them.
• The Gravy: The au jus gravy and brown gravy mix are both excellent in a Mississippi pot roast recipe. The brown gravy mix makes the roasting liquid a little thicker than the au jus.

How To Store Slow Cooker Pot Roast

Slow cooker roast with pepperoncini is terrific as leftovers. This shredded beef roast recipe will keep in an airtight container for 3-4 days in the fridge.

Freeze

Mississippi pot roast leftovers can be frozen for up to 3 months. A time-saving hack is to freeze shredded beef in individual portions for sandwiches or enough for a dish you plan to make.

Reheat

You want to be careful when reheating shredded beef so it doesn’t dry out. 

• Microwave – Always add some gravy/au jus to the shredded beef when microwaving. Cover it with a microwave-safe cover to trap the steam and retain moisture in the Mississippi pot roast. Run 60-90 seconds, then stir and check for hot spots. Return to the microwave, checking every 30-45 seconds, depending on the strength of your unit, until it’s as hot as you like.
• Oven or Toaster Oven – Use a glass dish and a piece of aluminum foil in a 325°F oven to reheat slow cooker beef. Spread shredded Mississippi pot roast evenly in a baking dish with juice and cover, baking until heated through. If your slow cooker roast seems dry, putting some thin butter pats here and there is a good hack.

Recipe Variations

• Sub in banana peppers for pepperoncini. They don’t have quite the tangy “bite” as pepperoncini. However, they are also very flavorful in a Mississippi pot roast, a touch sweeter, and pre-sliced into nice little wheels.
• Some folks like the added enhancement of a bay leaf in their Mississippi pot roast. And some claim a slow cooker roast doesn’t have status without the addition of garlic, and garlic, and more garlic!  
• Baby carrots tossed in with the roast as it cooks are a bright and flavorful addition to a slow cooker pot roast.
• Make a cornstarch slurry if you use the au jus mix, and prefer the Mississippi pot roast gravy to be a tad thicker. Add by the teaspoonful when you have lifted the roast out to shred. Stir and give the cornstarch a few minutes to do its thickening magic. Continue adding the slurry until you get the consistency you’d like.
