What is a Mississippi Roast?
A Mississippi Roast is a modern classic pot roast known for its signature five ingredients: chuck roast, a packet of ranch seasoning, a packet of au jus gravy mix, a stick of butter, and pepperoncini peppers. The recipe is rumored to have been created by Robin Chapman in Mississippi, and it gained widespread popularity through internet food blogs and social media. Its appeal is its incredible flavor and foolproof preparation method, making it a go-to for home cooks everywhere.

The 5 Simple Ingredients You’ll Need
The beauty of this recipe is its minimal ingredient list. You only need a handful of items to create these incredible pepperoncini beef sandwiches.
- Beef Chuck Roast: This cut is essential for a tender, shreddable result. Look for a 3-4 pound roast with good marbling.
- Au Jus Gravy Mix: This packet brings a deep, savory, and beefy flavor to the roast.
- Ranch Seasoning Mix: The secret ingredient! It adds a zesty, herby, and tangy flavor that perfectly complements the rich beef.
- Unsalted Butter: This adds richness and helps create a silky, flavorful gravy as the roast cooks.
- Pepperoncini Peppers: These provide a mild, tangy heat that cuts through the richness of the beef. You’ll use both the peppers and a bit of the brine from the jar.
How to Make Mississippi Roast Sandwiches (Step-by-Step)
Making these slow cooker pot roast sandwiches couldn’t be easier. Just follow these simple steps for perfect results.
- Prepare the Slow Cooker: Place the chuck roast in the bottom of your slow cooker. No need to sear it first!
- Add Seasonings: Sprinkle the entire packet of ranch seasoning mix and the au jus gravy mix evenly over the top of the roast.
- Top with Butter and Peppers: Place the stick of butter on top of the seasoned roast. Arrange the pepperoncini peppers around the butter. Pour about a half cup of the pepperoncini brine over the roast.
- Cook Low and Slow: Cover the slow cooker and cook on low for 8 hours. Do not be tempted to open the lid! Let the slow cooker work its magic.
- Shred the Beef: After 8 hours, the beef will be fall-apart tender. Use two forks to shred the meat directly in the slow cooker. Stir the shredded beef into the juices to absorb all that amazing flavor.
- Assemble Your Sandwiches: Toast your favorite buns, then pile them high with the shredded Mississippi roast. For an extra treat, add a slice of provolone cheese and let it melt over the warm meat.

Choosing the Best Buns
The right bun is crucial for a perfect sandwich experience. You need something sturdy enough to hold the juicy beef without falling apart. Hearty, crusty rolls like hoagie rolls or brioche buns are excellent choices. Toasting the buns is a non-negotiable step—it adds texture and helps prevent them from getting soggy. For a similar feel to our Philly Cheesesteak recipe, a good hoagie roll is key.
Tips for the Best Mississippi Roast
While this recipe is incredibly forgiving, a few tips can elevate it even further.
- Don’t Trim the Fat: The fat on the chuck roast renders down during the long cooking time, adding immense flavor and keeping the meat moist.
- Low and Slow is the Way to Go: Cooking on low for 8 hours ensures the most tender result. While you can cook it on high for 4-5 hours, the low and slow method yields superior texture.
- Don’t Add Extra Liquid: The roast will release plenty of its own juices, which combine with the butter and pepperoncini brine to create the perfect amount of liquid. Adding more will dilute the flavor.
Delicious Variations to Try
Want to mix things up? Here are a few popular variations on the classic recipe.
Make It Spicy
If you like more heat, use hot pepperoncini peppers or add a pinch of red pepper flakes along with the other seasonings.
Different Cuts of Meat
While chuck roast is traditional, this recipe also works well with other cuts like rump roast or sirloin tip roast. You could even try it with pork shoulder for a delicious pulled pork variation.
What to Serve with Your Sandwiches
These hearty sandwiches are a meal in themselves, but they also pair wonderfully with classic sides. Serve them with french fries, onion rings, a creamy coleslaw, or a simple side salad. For a truly comforting meal, pair it with a bowl of crock pot cheesy potato soup.
Storing and Reheating Leftovers
Leftover Mississippi roast stores beautifully. Keep the shredded meat and its juices in an airtight container in the refrigerator for up to 4 days. You can also freeze it for up to 3 months.
To reheat, simply warm the beef and juices in a saucepan over medium-low heat until heated through. You can also microwave it in short bursts. The leftovers are just as delicious, if not more so, as the flavors continue to meld. They are perfect for a quick lunch, similar to how you might enjoy leftover Oklahoma onion smash burgers. You can also use the leftover meat in creative ways, like in tacos, quesadillas, or over baked potatoes.
