WHAT IS MISSISSIPPI POT ROAST?

Mississippi pot roast is a slow-cooked beef roast seasoned with ranch mix, au jus seasoning, butter, and pepperoncini peppers.

Unlike a traditional pot roast filled with broth and vegetables, this version uses only a handful of ingredients. As the beef cooks, its natural juices combine with the butter and dry seasonings to make a savory sauce right in the crockpot.

The pepperoncini are mild rather than intensely spicy. They bring a light tanginess that cuts through the richness of the butter and beef.

And chuck roast is an ideal choice. It contains enough marbling to stay moist during the long cooking time and becomes especially tender when cooked slowly.

CROCKPOT MISSISSIPPI POT ROAST INGREDIENTS

You’ll need:

• 6 tablespoons of unsalted butter, divided
• 1 teaspoon of sea salt
• 1 teaspoon of black pepper
• 2 to 3-pound boneless beef chuck roast
• 1 tablespoon of minced onion flakes
• 1 packet of ranch seasoning mix
• 1 packet of au jus gravy mix
• 6 to 10 whole pepperoncini peppers
• Chopped fresh parsley for garnish, optional

Chuck Roast

Boneless chuck roast is one of the best choices for slow cooker pot roast. It has plenty of marbling, which slowly melts as the beef cooks.

Avoid choosing a roast that is extremely lean. A little visible fat helps keep the finished beef moist and gives the cooking juices a deeper flavor.

Ranch Seasoning Mix

A packet of ranch seasoning adds garlic, onion, herbs, salt, and a familiar savory flavor all at once.

Keep in mind that ranch packets can contain a fair amount of sodium. If salt is a concern, look for a lower-sodium variety.

Au Jus Gravy Mix

The au jus mix adds concentrated beef flavor and helps season the liquid that develops as the roast cooks.

There’s no need to prepare the packet according to its package directions. Add the dry seasoning directly to the crockpot.

Pepperoncini Peppers

Whole pepperoncini give the roast a slightly tangy flavor with just a mild bite.

Six peppers will keep the flavor fairly subtle. Add closer to ten if you really enjoy pepperoncini.

Butter

Unsalted butter adds richness and blends with the beef juices to create the sauce.

Using unsalted butter also gives you better control over the final salt level since the ranch and au jus mixes already contain seasoning.

MISSISSIPPI POT ROAST SUBSTITUTIONS AND ADDITIONS

BEEF: Chuck roast is our first choice because it becomes beautifully tender during slow cooking. Another slow-cooking beef roast can work, but look for a cut with visible marbling rather than something extremely lean.

PORK: You can replace the beef with a pork shoulder or pork butt for a different version of the recipe. Cooking time can vary depending on the size of the roast.

AU JUS: If you don’t have an au jus packet, a one-ounce packet of brown gravy mix can be used instead.

VEGETABLES: Add peeled carrots, chunks of onion, celery, or small potatoes around the beef if you’d like to turn the roast into a complete one-pot meal.

PEPPERONCINI: Add a little pepperoncini juice if you prefer a stronger tangy flavor. Start with a small amount since it can also increase the saltiness.

HOW TO MAKE CROCKPOT MISSISSIPPI POT ROAST

This recipe is very simple, but a quick sear before slow cooking gives the outside of the roast extra color and flavor.

Here’s how to make it:

STEP ONE

Heat one to two tablespoons of the butter in a large skillet over medium-high heat.

Let the skillet get hot before adding the beef. A properly heated pan helps the roast brown instead of simply steaming.

STEP TWO

Season both sides of the chuck roast lightly with the sea salt and black pepper.

Place the roast into the hot skillet and sear it until browned. Turn the beef and brown the opposite side as well.

You aren’t trying to cook the roast through at this point. You’re only building a browned crust on the outside.

PRO TIP:

If you’re using salted butter or particularly salty seasoning packets, reduce or leave out the added sea salt.

STEP THREE

Transfer the browned chuck roast to the crockpot.

Pour the remaining melted butter and all of those browned bits from the skillet over the meat.

Don’t leave those browned pieces behind. They add plenty of flavor to the finished cooking juices.

STEP FOUR

Sprinkle the minced onion flakes evenly over the top of the beef.

STEP FIVE

Sprinkle the ranch seasoning mix and au jus gravy mix over the roast.

You do not need to stir them into liquid. They will dissolve into the butter and natural beef juices while everything cooks.

STEP SIX

Cut the remaining butter into several pieces and place them over the top of the seasoned roast.

Arrange six to ten whole pepperoncini around and on top of the beef.

Cover the crockpot with the lid.

STEP SEVEN

Cook on LOW for eight hours, or until the beef is extremely tender and pulls apart easily with a fork.

Try not to remove the lid repeatedly while the roast cooks. Every time the lid is lifted, heat escapes and the cooking time can increase.

PRO TIP:

Low heat gives this cut of beef enough time to soften properly. You can cook a roast faster on high, but the texture may not be quite as tender.

STEP EIGHT

Once the beef is tender, use two forks to pull it apart into large chunks.

Stir the shredded meat gently into the cooking juices so all of those pieces get coated.

STEP NINE

Serve immediately. Sprinkle chopped parsley over the top if desired.

And don’t forget the juices left in the crockpot. Spoon them over the beef and whatever side dish you’re serving with it.

DO YOU HAVE TO SEAR MISSISSIPPI POT ROAST?

No. You can place the uncooked chuck roast directly into the slow cooker and continue with the recipe.

Searing is worth the few extra minutes when you have time, though. Browning the surface gives the beef a deeper roasted flavor and leaves flavorful browned bits in the pan that can be added to the crockpot.

Short on time? Skip it. The roast will still cook properly.

TIPS FOR THE BEST MISSISSIPPI POT ROAST

THAW THE MEAT FIRST: Don’t put a frozen roast directly into the crockpot. Thaw it completely in the refrigerator before cooking.

COOK ON LOW: Chuck roast becomes tender through long, gentle cooking. Eight hours on low gives you a better texture than trying to rush it.

WATCH THE SALT: Ranch seasoning and au jus can both contain quite a bit of sodium. Unsalted butter and reduced-sodium seasoning mixes are helpful if you prefer less salt.

DON’T ADD EXTRA LIQUID: The beef releases plenty of juice as it cooks. You generally don’t need broth or water for this recipe.

CHECK FOR TENDERNESS: The roast is ready when a fork slides easily into the meat and the beef separates without much resistance. If it still feels tough, it probably needs more time.

CAN I COOK MISSISSIPPI POT ROAST ON HIGH?

You can, but low heat is the better option for this particular recipe.

Chuck roast contains connective tissue that needs time to soften. Slow cooking allows that tissue to break down gradually, giving you moist, tender beef instead of a roast that still feels firm when sliced.

If your roast reaches the end of the expected cooking time but doesn’t pull apart easily, keep cooking it. A tough slow-cooked chuck roast is usually undercooked rather than overcooked.

WHAT TO SERVE WITH MISSISSIPPI POT ROAST

Creamy mashed potatoes are one of the best sides for Mississippi pot roast. They soak up the buttery, savory juices beautifully and turn the beef into a full comfort-food dinner.

Rice is another easy option, especially when you want something simple that won’t compete with the flavorful roast.

For vegetables, try green beans, glazed carrots, roasted carrots, corn, or steamed broccoli. If you want to cook everything together, potatoes and carrots can also be added directly to the slow cooker.

Soft dinner rolls or crusty bread are especially good for soaking up any sauce left on the plate.

For leftovers, pile the shredded beef onto toasted sandwich rolls and add a little of the cooking liquid before serving.

HOW TO STORE CROCKPOT MISSISSIPPI POT ROAST

This roast keeps well, making it a good option when you want to cook once and get several meals from it.

MAKE AHEAD

You can season and cook the roast a day before you plan to serve it.

Once cooked, cool the meat and juices before refrigerating them together. Keeping the beef in the cooking liquid helps prevent it from drying out.

When you’re ready to eat, reheat everything gently until hot.

IN THE FRIDGE

Store leftover Mississippi pot roast in an airtight container in the refrigerator for up to four days.

Add some of the cooking juices to the container with the meat. They keep the shredded beef moist and flavorful.

IN THE FREEZER

Let the roast cool completely before freezing.

Place individual portions or a larger batch into freezer-safe airtight containers. Include some cooking liquid with each portion, leaving a little room at the top of the container for expansion.

Freeze for up to three months.

Thaw frozen pot roast overnight in the refrigerator before reheating.

REHEATING

Reheat the beef slowly on the stovetop over low heat with some of its juices, stirring occasionally until hot.

You can also reheat individual servings in the microwave. Cover the dish and heat in short intervals so the edges don’t dry out before the center gets warm.

CROCKPOT MISSISSIPPI POT ROAST FAQS

Why is my Mississippi pot roast tough?

It probably needs more cooking time.

Chuck roast doesn’t become tender the moment it reaches a safe temperature. The connective tissue needs additional time to soften. Keep cooking until the beef separates easily when pulled with a fork.

Can I put a frozen roast in the crockpot?

No. Thaw the roast completely before adding it to your slow cooker.

A frozen roast can spend too much time warming slowly before the center reaches the proper temperature, and it won’t cook according to the timing given in this recipe.

Is Mississippi pot roast spicy?

Not very.

Pepperoncini peppers have a mild heat and a noticeable tangy flavor. They give the beef a little zip without turning it into a particularly spicy dish.

Can I add potatoes and carrots?

Yes. Potatoes, carrots, onions, and celery can all be added around the roast.

Cut the vegetables into fairly large pieces so they can stand up to the long cooking time without becoming too soft.

Do I need to add water or beef broth?

No additional liquid is needed for the basic recipe.

The chuck roast releases liquid as it cooks, while the butter melts into those juices. By the end of the cooking time, there should be plenty of flavorful liquid in the bottom of the crockpot.

Can I use salted butter?

Yes, but be careful with additional salt.

Both ranch seasoning and au jus mix are already salty. If you use salted butter, leave off the sea salt when seasoning the beef or use reduced-sodium packets.

Can I use brown gravy instead of au jus?

Yes. Substitute a one-ounce packet of brown gravy mix for the au jus seasoning.

The flavor will be slightly different, but it works well with the ranch, butter, and beef.

How do I know when the roast is done?

Don’t rely only on the clock.

After about eight hours on low, test the roast with a fork. When the meat separates with almost no resistance, it’s ready to shred.
