When I lift the slow cooker lid, the beef is sitting in a peppery, buttery cooking liquid, and it pulls apart with almost no effort. That’s the starting point for Mississippi Pot Roast Sliders: tender shredded chuck tucked into soft Hawaiian rolls with melted provolone. They’re hearty without needing a pile of extra toppings, and the sweet rolls balance the savory beef in every bite.
I keep the rolls connected as I slice them, then build the sliders as one easy-to-handle sandwich before separating them after baking. The roast gets its tang from pepperoncini and their brine, while a little reserved cooking liquid keeps the shredded beef moist inside the rolls. Once the cheese melts and the tops turn golden, the sliders are warm, savory, and just tangy enough.
Kitchen Note
Keep the rolls joined when you cut them horizontally, then lift off the top as one piece. It’s much easier to line it back up after the beef and cheese are in place.
Save these Mississippi Pot Roast Sliders for a crowd-pleasing meal with tender pepperoncini beef, melted provolone, and golden Hawaiian rolls.
The Brine Isn’t the Cooking Liquid—and the Sliders Need Both
Pepperoncini brine and the liquid that collects around the roast do different jobs. The brine brings a tangy, salty note as the beef cooks; the reserved cooking liquid is what I stir into the shredded meat before it goes into the rolls. That small distinction keeps the filling moist without pouring all the slow cooker liquid over the bread.
After cooking, the liquid has picked up beef juices, butter, and seasoning. Skim off the excess fat first, then measure the portion for the filling. Using only the reserved half cup lets the beef stay juicy while the rolls hold their shape. Add more liquid than that and the bottom rolls can turn soggy before the provolone has a chance to set around the meat.
The other useful balance is sweet against savory. Hawaiian rolls bring a soft, lightly sweet bite that works especially well with the tang of pepperoncini and the rich beef. Provolone melts into the layers without taking over. Each part has a job: the brine brightens, the cooking liquid moistens, and the cheese helps hold the filling together.
Why Chuck, Seasoning Mixes, and Provolone Fit These Sliders
- Boneless chuck roast — Chuck has enough connective tissue and marbling to turn tender during a long, covered cook. Choose a roast that fits comfortably in the slow cooker; thaw it before it goes in. After shredding, pull away any large pieces of fat so the filling stays pleasant to eat.
- Ranch and au jus seasoning — The ranch mix brings its familiar herb-and-tang character, while au jus mix deepens the beefy, savory taste. Together they season the roast and its cooking liquid without needing a separate sauce. Use fresh, dry packets; seasoning that has clumped from moisture won’t sprinkle as evenly.
- Pepperoncini and brine — The peppers add a mild, bright tang, and their brine carries that flavor through the cooking liquid. If you prefer less heat, choose mild pepperoncini rather than hot ones; the brine still gives the roast its distinctive lift.
- Hawaiian rolls and provolone — The rolls’ slight sweetness balances the seasoned beef, and keeping them connected makes the assembled sliders easier to handle. Provolone melts smoothly and has a mild taste, so it complements rather than masks the roast.
- Butter, garlic powder, and dried parsley — This trio makes a simple brush-on topping for the rolls. Melt the butter just before mixing so the garlic powder and parsley distribute across the surface instead of clumping.
Slow-Cook the Beef, Then Build the Sliders in One Layer
Let the chuck turn fork-tender
Set the thawed roast in a 6-quart slow cooker and sprinkle the ranch and au jus mixes over it. Add the butter, pepperoncini, and brine around the roast, then cover. Cook on LOW for 8 to 9 hours or HIGH for 4 to 5 hours, until the beef is fork-tender and reaches at least 145°F in the center. The clock gives you a window, but the meat should pull apart easily before you move on.
Shred the beef and reserve the right amount of liquid
Transfer the roast to a cutting board and shred it with two forks, discarding large pieces of fat as you go. Skim excess fat from the slow cooker liquid, then reserve half a cup for the filling. Don’t skip the skimming: excess fat can leave the beef slick rather than juicy. Keep the rest of the liquid nearby only if you want it at the table; the slider filling uses the reserved portion.
Layer the meat between the rolls and cheese
Heat the oven to 350°F and line a 9×13-inch baking dish with parchment paper. Slice the connected rolls horizontally and place the bottom half in the dish. Layer on half of the provolone, all of the shredded beef, and the remaining provolone, then stir the reserved cooking liquid into the beef and set the roll tops in place. Spreading the meat to the edges helps keep each slider equally filled.
Brush, bake, and let the cheese settle
Melt the remaining butter and stir in the garlic powder and dried parsley. Brush the mixture over the roll tops, covering the surface so they brown evenly. Bake for 12 to 15 minutes, until the cheese is melted and the tops are golden brown. Rest the pan for 5 minutes before separating the sliders; that brief pause gives the hot cheese a moment to settle around the filling.
Easy Swaps for Different Tastes and Dietary Needs
Milder Banana Pepper Sliders
Replace the pepperoncini with mild banana peppers and use banana pepper brine in their place, keeping the same quantities. The roast stays tangy, but the pepper flavor is gentler and less distinctive.
A Nuttier Cheese Layer
Use sliced Swiss in place of the provolone, keeping the same amount. Swiss gives the sliders a more pronounced, nutty cheese flavor while still melting into the beef; provolone is milder if you want the pepperoncini to stand out.
A Gluten-Free Version
Choose gluten-free Hawaiian-style rolls and gluten-free ranch and au jus seasoning packets, using the same quantities as the regular versions. The rolls may be less pillowy, so handle the connected top gently when assembling; the beef and melted cheese will still make a satisfying filling.
Storage and Reheating
- Refrigerator: Store leftover sliders in an airtight container for 3 to 4 days. The rolls soften as they sit against the beef.
- Freezer: For the best texture, freeze the cooked shredded beef with some cooking liquid in an airtight container for up to 3 months. Thaw it in the refrigerator before assembling fresh sliders.
- Reheating: Reheat assembled sliders covered in a 350°F oven until the center reaches 165°F. Uncover near the end if you want the tops to crisp; leaving them uncovered the whole time can dry out the rolls.
