Slow Cooker Mississippi Pot

Slow Cooker Mississippi Pot Roast is a fork-tender, flavor-packed dinner that practically makes itself. With just five simple ingredients, you get rich, savory meat with a tangy kick that’s downright delicious.

This recipe is one of my go-to comfort meals because it’s the kind I know will turn out perfectly every time. Plus, the slow cooker does all the work – how can you beat that?

Serve it over mashed potatoes, and everyone will want seconds of this fuss-free dish!

Ingredients You’ll Need

• Chuck Roast: This cut is ideal for slow cooking because it’s loaded with fat, which melts down and creates incredibly tender, fall-apart meat. I always look for one with plenty of marbling for maximum flavor.
• Pepperoncini Peppers & Juice: These tangy, slightly spicy peppers add a zesty kick that balances the richness of the meat and butter. Meanwhile, the juice is the secret ingredient for the tangy, savory flavor. It also tenderizes the meat!
• Unsalted Butter: A cubed stick of butter melts into the meat, creating a rich, silky sauce. I prefer unsalted so I can control the saltiness — plus, the seasoning packets already have plenty of flavor.
• Au Jus Gravy Mix: This brings a savory, beefy depth to the roast. It thickens the juices slightly and enhances the meaty flavor without overpowering the other ingredients.
• Buttermilk Ranch Dressing Mix: A simple packet of ranch seasoning adds a creamy, herby kick that’s key to the recipe’s signature flavor. I always use the classic buttermilk version for the best balance of tang and richness.

What Is the Best Cut of Beef for Mississippi Pot Roast?

You have a few options here. And since it cooks low and slow, most cuts of beef will come out wonderfully tender.

I almost always go for boneless chuck roast because it’s easier to work with and shreds better. But you can use bone-in if you prefer.

Here are my recommendations:

• Boneless Beef Chuck Roast. This is my top choice. It comes from the shoulder of the cow and becomes incredibly tender when cooked. Best of all, a beautifully marbled chuck roast is super affordable and easy to find.
• Rump Roast. This is my second favorite cut of beef. Get the bottom or the top round because they’re lean and easy to cut.
• Beef Brisket. This might be an odd one, but it’s very fatty, which means it’s very tender. It makes for a flavorful pot roast – though it’s more expensive.
• Pork Butt, Pork Roast, or Shoulder. If you’re not a beef eater, they’ll work just as well.

How to Make The Best Mississippi Pot Roast

I think the hardest part of making this Mississippi pot roast recipe is waiting for it to finish cooking! I love that it’s mostly hands-off, yet the results are unbelievably tender and flavorful.

Of course, the magic happens when you let it go low and slow, and the end result is a roast that’s rich, buttery, and incredibly tender.

Sear the Meat (Optional):

Warm 2 to 3 tablespoons of oil in a large skillet over medium-high heat. Sear the chuck roast on all sides until well browned, about 3 to 4 minutes per side. This step isn’t required, but I highly recommend it for extra flavor and those rich, caramelized edges.

Load the Slow Cooker:

Place the chuck roast in your slow cooker and top with the pepperoncini, pepperoncini juice, butter, au jus gravy mix, and ranch packet. No extra liquid is needed — the roast will create its own rich, flavorful sauce as it cooks.

Cook Low and Slow:

Cover and cook on LOW for 8 to 10 hours or until the roast is fall-apart tender. Low and slow is the key here — it’s worth the wait!

Rest the Meat:

Carefully transfer the roast to a chopping board, loosely cover it with foil, and let it rest for about 10 minutes. This helps the juices redistribute throughout the meat, ensuring it stays extra moist and flavorful when shredded. Skipping this step won’t ruin your roast, but I’ve found it makes a noticeable difference in both texture and taste.

Shred and Return to the Juices:

After resting, use two forks to shred the meat. Add the shredded beef back into the slow cooker and stir everything together so the meat soaks up all those flavorful juices. Let it sit for another 15 to 20 minutes for maximum flavor.

Serve and Enjoy:

Dish it up with mashed potatoes, rice, or tucked into a sandwich — whatever you choose, you’re in for a deliciously tender, buttery roast!

Tips for Making the Best Crockpot Roast

A tender, flavorful pot roast is all about a few simple tricks — and trust me, they make all the difference! Whether you’re slow-cooking in a crockpot, using a Dutch oven, or trying the Instant Pot method, these tips will help you nail it every time.

• Bring the Meat to Room Temperature: If you have time, let your chuck roast sit at room temperature for 30 to 45 minutes before cooking. This helps it cook more evenly and results in juicier, more tender meat.
• Cook Low, Not High: For the most tender, fall-apart roast, always cook it on LOW for 8 to 10 hours. Cooking on HIGH speeds things up, but the meat won’t break down as well and can actually come out tough. Low and slow is the secret to melt-in-your-mouth perfection.
• Make Your Own Ranch Seasoning: If you can’t find a packet dry ranch dressing mix, make your own! Combine 2 tablespoons dried buttermilk powder, 1 tablespoon dried parsley, 1 teaspoon each dried dill, onion powder, and garlic powder, 1/2 teaspoon each dried chives and salt, and 1/4 teaspoon pepper.
• Want More Gravy? Add 1 cup of beef broth to the slow cooker with all the other ingredients. To thicken it after cooking, mix 1 tablespoon of cornstarch with 2 tablespoons of water, then stir into the juices. Stir and let thicken while the meat rests.
• Try the Dutch Oven: Don’t have a slow cooker? No problem! Sear the roast in a Dutch oven, then add the remaining ingredients. Cover and cook in the oven at 300°F for 3 to 4 hours or until the meat is tender and shreds easily. It’s a great option if you’re short on time.
• Instant Pot Method for Speed: Sear the roast using the Sauté function, then add the remaining ingredients plus about 1/2 cup of beef broth. Cook on Manual (High Pressure) for 60 to 70 minutes, followed by a 15-minute natural release. The result? A roast that’s still tender and packed with flavor — in a fraction of the time!

How to Store & Freeze Leftovers

When this is on my menu, I always make extra because the leftovers are just as good — if not better — the next day. Whether you’re saving it for sandwiches, rice bowls, or easy meal prep, here’s how to keep your roast fresh and delicious.

• To Store: Let the meat cool fully, then place in an airtight container. Refrigerate for 3 to 4 days.
• To Freeze: For best results, freeze the cooled roast with the juices to prevent it from drying out. Use a freezer-safe bag or airtight container, and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
• To Reheat in the Microwave: Reheat in 30-second intervals, stirring in between, until warmed through.
• To Reheat in the Oven: Place the roast in a baking dish, cover with foil, and heat at 325°F for 20 to 30 minutes or until warmed through.
• To Reheat on the Stovetop: Heat the meat in a skillet over medium heat with a splash of the juices until hot.

Note: For the best results, always reheat with the juices — it keeps the meat tender, flavorful, and just as delicious as when it was first made!
