What do you need to make Mississippi Pot Roast?

This recipe is famous because it is simple. You do not need fancy ingredients, and you can usually find everything at a regular grocery store. I also like that it is forgiving. If your roast is a little bigger or smaller, it still works.

Ingredients that make the magic happen

• Chuck roast (about 3 to 4 pounds is perfect)
• 1 packet ranch seasoning mix
• 1 packet au jus gravy mix
• Butter (usually 6 to 8 tablespoons, adjust to your taste)
• Pepperoncini peppers (5 to 10 peppers, plus a splash of the juice if you like extra tang)
• Optional: a little black pepper, since the packets already bring plenty of flavor

If you love the comfort of classic beef dinners, you might also like this classic slow cooker pot roast. It is more traditional, with that Sunday dinner vibe.

One quick shopping tip: chuck roast is my favorite here because it has enough fat to stay juicy during the long cook. Leaner cuts can work, but they can end up a bit dry unless you are careful.

How do you make Mississippi Pot Roast?

This is the part I love. It is basically layer, set, and forget. Your house will smell incredible, and you will feel like you have your life together even if the laundry is still sitting in a basket.

• Put the chuck roast in the bottom of your crock pot.
• Sprinkle the ranch seasoning and au jus mix over the top.
• Place the butter right on top of the roast.
• Add the pepperoncini peppers around the roast. If you want it more tangy, add 1 to 3 tablespoons of pepperoncini juice.
• Cover and cook on low for 8 hours or high for 4 to 5 hours, until it shreds easily with a fork.

When it is done, I shred it right in the slow cooker and stir it around so the meat soaks up the buttery, savory juices. That is where the payoff is. This is also where I usually sneak a taste straight from the pot. For quality control, obviously.

I made this for my family last weekend and everyone went back for seconds. The pepperoncini flavor was the surprise hit, not spicy, just really tasty. It is officially on our monthly meal list now.

Serving ideas: I love it over mashed potatoes, but it is also amazing on rice, egg noodles, or piled onto sandwich rolls with a little of the juice spooned on top.

How do you make Mississippi Pot Roast in the Instant Pot?

If you forgot to start the slow cooker in the morning, I have been there. The Instant Pot version is a lifesaver when it is already late afternoon and people are asking what is for dinner.

Quick Instant Pot method

Here is how I do it in a simple, no stress way:

• Cut the chuck roast into 3 to 4 big chunks so it cooks more evenly.
• Use saute with a little oil and brown the pieces on both sides if you have time. This adds flavor, but you can skip it on a busy day.
• Turn off saute. Add 1 cup beef broth or water to help it come to pressure.
• Add ranch mix, au jus mix, butter, and pepperoncini peppers, plus a little juice if you want.
• Cook on high pressure for about 60 to 70 minutes, then let it naturally release for 15 minutes before quick releasing the rest.

After that, shred the beef and stir it into the juices, just like the crock pot method. It will still give you that signature tangy, savory taste that makes Crock Pot Mississippi Pot Roast with Pepperoncini such a crowd pleaser, even when you do it faster.

On nights when I am leaning into comfort food, I rotate this roast with cozy crock pot classics like crock pot chicken and dumplings. Both feel like a warm blanket in dinner form.

Recipe Variations

Once you make this once, you start thinking of little tweaks based on what your family likes. The base recipe is solid, but here are a few easy ways to change it up without ruining the whole point, which is easy comfort food.

Make it a little less rich: Use 4 tablespoons of butter instead of a whole stick. It still tastes great.

Make it a little more tangy: Add a few extra tablespoons of pepperoncini juice. This is my personal favorite move.

Add veggies: Toss in baby carrots or sliced onions. I usually add them halfway through if I do not want them super soft.

Turn it into sandwiches: Shred the beef, pile it onto rolls, and add provolone. Broil for a minute and it is ridiculous in the best way.

Make it stretch further: Serve it over mashed potatoes or noodles, and add a simple green salad on the side.

If you are feeding a hungry crew and want another easy dinner idea for your list, crock pot cowboy casserole is super filling and very weeknight friendly.

Common Questions

Do I need to add any water or broth in the slow cooker?

Nope. The roast releases liquid as it cooks, and the butter and pepperoncini add more. If your roast is very lean, you can add a small splash of broth, but I usually do not.

Is it spicy with the pepperoncini?

It is more tangy than spicy. If you are sensitive to heat, use fewer peppers and skip the extra juice.

Can I use a different cut of beef?

Chuck roast is the easiest and most reliable. You can use brisket or rump roast, but the texture can be a little different.

How do I store and reheat leftovers?

Store it with the juices in an airtight container in the fridge for up to 4 days. Reheat gently on the stove or in the microwave, adding a spoonful of juice so it stays moist.

What goes best on the side?

Mashed potatoes are my number one. Rice, egg noodles, or roasted veggies are also great, especially if you want something to soak up the juices.
