Slow Cooker Pepperoncini Roast

If you like pot roast with huge flavors – without much effort – this Slow Cooker Mississippi Roast Recipe is one you’re going to love forever and ever.

I had never heard of a crock pot Mississippi Roast until recently – but the second I tasted it, I was in love forever.

Mississippi Pot Roast is so simple and easy -but bursting with rich meaty flavor and a little bit of zip from pepperoncini peppers and hearty aus jus gravy.

This roast doesn’t even require pre-browning, so it is lightning quick to prepare – just add to a slow cooker, set it, and go about your day. When you come back at night, simply shred the roast, serve, and enjoy!

Can you get any easier than that for a delicious pot roast dinner? I don’t think so!

I truly love this Mississippi Roast recipe, and hope you love this delicious and easy slow cooker pot roast as much as I do!

Mississippi roast is a huge pinterest favorite – it’s been all over the internet for a long time, and for a reason.

Mississippi roast is a simple rich and slightly tangy pot roast that is incredibly quick and easy to prepare – simply add ingredients and set the timer for a delicious dinner.

The original recipe of this family favorite roast recipe centers around just five ingredients – au jus packets, pepperoncini peppers, a stick of butter, and ranch dressing seasoning.

From time to time however, I skip adding the au jus gravy mix and just add the peppers, butter, and ranch dressing seasoning packet – and it’s still amazingly delicious, tender, and full of flavor.

You can also swap out ranch dressing seasoning for onion soup mix for a little bit of a different roast flavor that is still melt in your mouth delicious!

If you’re wondering what cut of meat makes the best Mississippi Roast – or any pot roast – it can be a bit confusing, since many stores and meat markets label cuts of meat differently, and might cut or package them differently than you’re used to – so I find it’s important to learn about the cuts you’re looking for, and know why they make a deliciously tender roast.

When going for a Mississippi Roast, or any pot roast dinner, you want to buy a tougher cut of beef.

This means lean cuts of meat with lots of connective tissue and very little fat, usually parts of the animal that move a lot and would be incredibly tough and hard to chew if you simply tossed it in a pan or on the grill like a steak.

When you cook down tougher meats, the collagen in the tissues breaks down into gelatin, which tenderizes your meat and adds a delicious meaty flavor to your sauce for a gravy that can’t be beat.

What Meat For Mississippi Roast Recipe:  


From the front part of the cow. Look for chuck roast, shoulder steak, boneless chuck roast, chuck shoulder pot roast, chuck seven-bone pot roast, or beef chuck arm.


From the breast or lower chest of the cow. The flat cut is leaner, and the point cut has more fat. Be sure to trim off any excessive fatty areas before slow cooking in this recipe.


From the rear leg area of the animal. Look for rump roast or bottom round.

Can You Freeze Mississippi Roast

Mississippi Roast isn’t just great because it is delicious and so easy – it’s also insanely versatile and takes well to freezing and reheating without getting tough or drying out, so saving leftovers in the freezer is a great option!

You can also make a giant batch of this roast and freeze it in individual portion sizes if you’re eating for one or two without having to slog through the same meal for leftovers day after day – this pot roast is just as delicious reheated as it is right out of the slow cooker.

There are two issues you want to be aware of when freezing and thawing cooked meat (or really anything) – you want to minimize the formation of ice crystals, and you want meat to be able to thaw quickly and evenly on it’s own in the refrigerator.

For best results when freezing:

Don’t overstuff roast into freezer bags to make a giant, thick blob – anytime I freeze anything I try to lay it in a bag so the meat can lay flat and not be too full because I want it to thaw evenly and quickly.

When adding to a plastic or freezer bag, lay the bag flat instead of piling in meat from the top, so you can spread it out and not make a big round shape in the middle.

Lay bags flat in the freezer until they “set”, at which point you can move them around to wherever fits best.

Again – you want it to thaw evenly, so a flatter, thinner shape will thaw naturally faster than a big, thick, rounded clump.

Let roast thaw in the refrigerator naturally for best results.

If in a hurry, I prefer to add frozen Mississippi roast to a pan with a little beef stock on medium low until piping hot.

Instant Pot Mississippi Roast

Like other roasts, Mississippi Roast is delicious in an Instant Pot – and the only thing you need to change is the cooking time and the liquid since you’re not slow cooking the roast, and rely on liquid for steam to pressurize the instant pot.

To convert this recipe to be a delicious Instant Pot Mississippi Roast, follow these tips:

Add all ingredients to the instant pot (save the butter for the very top).

Set instant pot to seal and cook on high pressure for about 80 minutes.

Let release naturally.

If your roast is over 4 pounds, I suggest increasing cook time to 90 minutes.

    I am an amateur. Is there no liquid added to crockpot?

    1. Courtney ODell says:

      There isn’t any – the butter and fat from the roast will create a rich gravy in the slow cooker, there is no additional liquid needed!
