Mississippi Pot Roast Sliders Recipe: Pepperoncini-Infused Party Pleasers

These sliders redefine party food with their irresistible blend of tender pot roast and bold Mississippi flavors. The slow-cooked beef absorbs every ounce of the pepperoncini-infused juices, creating a filling that’s both hearty and packed with character.

Assembling them is simple: pile the shredded roast onto soft Hawaiian rolls, then top with melted provolone. The result is a perfectly balanced combination of savory, tangy, and slightly spicy that guests can’t resist.

What makes these sliders special is their ability to feed a crowd without sacrificing quality. Each bite delivers the rich, fall-apart texture of the pot roast paired with the creamy cheese and buttery rolls.

Serve warm for the ultimate comfort food experience at your next gathering. The flavors only deepen as they sit, making them ideal for parties.

Ingredients for Mississippi Pot Roast Sliders

Party-size flavors packed into these irresistible sliders with tender beef and bold toppings.

The beef is everything here. Chuck roast with good marbling breaks down beautifully during the long cook. Look for Costco or Sam’s Club for bulk packs—more economical for feeding a crowd. The pepperoncini peppers (don’t skip the juices!) add that signature tang. Meijer or Kroger usually stocks the big jars near the pickles.

No ranch or au jus packets? Homemade mixes work too—just combine the right ratios of spices. Provolone can be swapped for Swiss or mozzarella (whatever melts well). Hawaiian rolls are key for that sweet-savory balance, but potato rolls in a pinch work as a backup. The mayonnaise is just for moisture—skip it if you prefer.

Sliders hold up well for 2-3 hours at room temp during parties. Store leftovers wrapped in foil for up to 4 days. The pot roast freezes beautifully for 3 months—perfect for making ahead.

Step-by-Step Instructions for Mississippi Pot Roast Sliders

This method turns tough chuck roast into tender, flavor-packed sliders that’ll disappear fast at any gathering.

Step 1: Season and Slow-Cook the Chuck Roast

Place the 3 lb chuck roast in the slow cooker. Sprinkle the ranch seasoning mix and au jus seasoning mix evenly over the top, pressing lightly so it adheres. Add the yellow onion (sliced), 4 cloves garlic cloves, and the entire 1 jar pepperoncini peppers—juices and all.

Pour in the 1 cup beef broth and 2 tbsp Worcestershire sauce. Top with the 0.5 cup unsalted butter (cubed). The liquid should mostly cover the meat. Cook on low for 8-10 hours or high for 5-6 hours until the roast shreds easily with a fork.

Step 2: Shred and Mix the Meat

Once the chuck roast is fall-apart tender, remove it from the slow cooker and shred it using two forks. Discard any large fat chunks. Return the shredded meat to the slow cooker and toss it with the cooking juices, onions, and pepperoncini.

This step ensures every bite soaks up the tangy, savory liquid. Let it sit in the warm juices for 10-15 minutes to absorb maximum flavor before assembling. The meat should be moist but not soupy—if it seems too wet, use a slotted spoon when serving.

Step 3: Prepare the Hawaiian Rolls

Slice the 12 whole Hawaiian rolls in half horizontally, keeping them connected if possible. Spread the 0.5 cup mayonnaise evenly across the bottom halves. This adds richness and helps protect the rolls from getting soggy.

Layer the 12 slices provolone cheese on top of the mayonnaise. The cheese will melt slightly from the warmth of the meat, creating a perfect bond. Keep the top halves of the rolls nearby—you’ll need them next.

Step 4: Assemble and Serve the Sliders

Using a slotted spoon, pile the shredded chuck roast mixture onto the cheese-covered bottom buns. Press down gently so the meat adheres. Place the top halves of the rolls over the meat to close the sliders.

For serving, you can either serve them as-is or return the assembled sliders to the slow cooker (or a warm oven at 200°F) for 10-15 minutes to melt the cheese completely. Slice into individual sliders and serve warm with extra pepperoncini on the side.

Pro Cooking Tips for This Dish

Slow Cooker Setup

For even cooking, place a rack or crumpled foil under the chuck roast to elevate it slightly. This prevents the bottom from stewing in its juices. I always use my 6-quart Crock-Pot for this recipe—it’s the perfect size for 3 lbs of meat. 🌡️

Butter Distribution

Instead of dumping all ½ cup butter on top, dot it around the edges of the slow cooker. This helps it melt evenly over the roast as it cooks. The butter will carry the ranch and au jus flavors deep into the meat.

Shredding Technique

Use two forks to shred the roast directly in the slow cooker—this keeps the juices contained. Pull the meat against the grain for the most tender texture. I discard any large fat chunks but leave smaller pieces for extra flavor.

Roll Preparation

Lightly toast the Hawaiian rolls in a 350°F oven for 3-4 minutes before assembling. This creates a barrier against sogginess. Brush the tops with melted butter for extra richness and shine.

Warm Holding

To keep sliders warm for a crowd, arrange them on a baking sheet and tent with foil. Place in a 200°F oven for up to 30 minutes. The cheese stays melted and the rolls stay soft without drying out. 💡

Juice Management

If your pot roast seems too wet after shredding, let it sit in a colander over the slow cooker for 5 minutes. This drains excess liquid while keeping the meat moist. Save the juices for dipping or au jus.
