Gathering the right ingredients is surprisingly straightforward with this recipe, yet each one plays an essential role in building the incredible flavor, tender texture, and inviting aroma that make these sandwiches unforgettable.

3-4 pound beef chuck roast: The star of the show, perfect for slow cooking to achieve that tender, shreddable texture.
1-2 tablespoons avocado oil: A high smoke-point oil that helps develop a beautiful crust on the roast during searing.
1 large sweet onion (sliced): Adds a mild sweetness and depth of flavor to the slow-cooked pot roast.
3 cloves garlic (minced): Infuses the dish with savory notes that complement the beef perfectly.
1 ounce packet ranch dressing mix: Brings a subtle tang and herbaceous kick to the sauce.
1 ounce packet au jus gravy mix: Enriches the gravy, making it flavorful yet light enough to soak into the sandwich bread.
1 cup sliced pepperoncini peppers (or 10 whole peppers plus 1/4 cup juice): Provides a zesty and slightly spicy bite that balances the richness of the beef and butter.
6 tablespoons unsalted butter: Melts into the sauce creating luscious richness and mouthfeel.
Sourdough or hoagie rolls: Ideal for holding all the juicy goodness without getting soggy.
A little oil for brushing the rolls (optional): Helps toast the bread to a perfect golden crisp.
Provolone cheese slices: Melts beautifully over the hot roast, adding a creamy layer of flavor.
Parsley for garnish (optional): A fresh, colorful touch that brightens up the finished sandwich.
Chips for serving: A crunchy sidekick that complements the juicy, tender meat perfectly.

How to Make Mississippi Pot Roast Sandwiches Recipe

Step 1: Searing the Roast

Start with heating a cast iron skillet over medium-high heat and adding the avocado oil. Sear your chuck roast on all sides, about 5-8 minutes per side, until you get that gorgeous brown crust. This step locks in the flavor and creates a beautiful texture contrast with the tender meat inside. Then, transfer the roast to your slow cooker to start the magic of low-and-slow cooking.

Step 2: Adding the Flavor Boosters

Surround the roast with the sliced sweet onions, then sprinkle the ranch dressing mix and au jus gravy mix evenly over the top. Next, add slices of butter, the pepperoncini peppers along with their juice, and finish with the minced garlic. Each of these ingredients will melt together into a rich, tangy sauce that bathes the beef in unforgettable flavor as it cooks.

Step 3: Slow Cooking to Tender Perfection

Cover your slow cooker and cook on LOW for 6 to 8 hours or on HIGH for 4 to 6 hours, depending on your timeline and the size of the roast. You’ll know it’s ready when the meat falls apart at the touch of a fork—it will be so tender you can’t wait to start making those sandwiches.

Step 4: Shredding and Mixing

Carefully transfer the tender roast to a baking tray or chopping board and shred it using two forks. This is where the fun begins because that shredded beef is going to soak up all the delicious juices left behind. Return the shredded meat to the slow cooker, stir it into the sauce, and get ready for assembly!

Step 5: Preparing the Rolls

Preheat your oven to 425 degrees Fahrenheit. Slice the sourdough or hoagie rolls lengthwise, but don’t cut them all the way through—keeping the top connected ensures that the meat stays piled in. Brush the tops lightly with oil to get an irresistible golden toast, then place the rolls on a baking tray and into the oven for 3-5 minutes until perfectly toasted.

Step 6: Building the Sandwiches

Fill each toasted roll with a generous scoop of the juicy shredded beef. Top with extra pepperoncini if you love that tangy kick, and don’t hold back on the provolone cheese slices that melt right into the warm meat. If you want, add fresh lettuce or onions for crunch, then transfer your creation to a serving platter. Serve alongside some of the leftover gravy and crunchy chips for an unbeatable meal.

Garnishes

Make Ahead and Storage

Storing Leftovers

Leftover roast and sauce can be stored in an airtight container in the refrigerator for up to 3 days. Keeping them together allows the flavors to deepen even more as they rest, making your next sandwich just as delicious as the first.

Freezing

If you want to keep this delicious meal longer, freeze the shredded roast and juices in a sturdy freezer bag or container for up to 3 months. Thaw overnight in the refrigerator before reheating, so it retains its juicy tenderness and flavor.

Reheating

The best way to reheat your Mississippi Pot Roast Sandwiches Recipe leftovers is gently in a saucepan over low heat, stirring occasionally to keep the meat moist. Alternatively, microwave in short bursts with a splash of beef broth or water to keep the roast from drying out. Reheat your rolls separately to maintain the toasted texture.

FAQs

Can I use a different cut of beef for the pot roast?

While chuck roast is ideal because of its marbling and slow-cook tenderness, other cuts like brisket or rump roast can work as well. Just make sure they are suitable for slow cooking to get that tender, shred-ready texture.

What if I don’t have pepperoncini peppers?

Pepperoncini add a unique tangy spice, but you can substitute with mild banana peppers or pickled pepper slices. Adding a splash of vinegar or lemon juice can help mimic the bright acidity pepperoncini provide.

Can I make this recipe in an Instant Pot?

Yes, you can adapt the recipe for an Instant Pot by searing the roast first on sauté mode, then cooking under high pressure for about 60-75 minutes. Natural release will help keep the meat tender and juicy.

How spicy will this dish be?

The spice level is generally mild, thanks to the gentle heat of the pepperoncini. If you prefer more heat, you can add a pinch of crushed red pepper flakes or hot sauce when mixing the shredded beef.

What type of bread works best for these sandwiches?

Sourdough or hoagie rolls are perfect because they’re sturdy enough to hold the juicy meat and soak up the flavorful gravy without falling apart. You can also try ciabatta or kaiser rolls for a similar effect.
