• 3 lbs chuck roast (cut into 1 lb chunks): The perfect cut for tender, flavorful meat that shred beautifully after pressure cooking.
• 2 tablespoon vegetable oil: Essential for searing the roast, locking in juices and creating a deep caramelized flavor.
• 1 small onion (diced): Adds sweetness and a subtle aromatic depth to the cooking liquid.
• 9 pepperoncini (whole): Bring a mild heat and tangy brightness that’s signature to this recipe.
• ½ cup pepperoncini juice: Intensifies the zesty flavor and balances the richness of the beef and butter.
• 1 ½ cups low sodium beef broth: Forms the base for a savory, comforting sauce without overpowering the other flavors.
• 1 oz dry ranch dressing mix: Adds a creamy, herby seasoning that enhances the overall taste.
• 1 oz au jus mix: Provides a rich, beefy boost to the cooking liquid.
• 4 tablespoon butter: Melts into the sauce for a silky texture and rich mouthfeel.
• 3 tablespoon all-purpose flour: Combined with butter to create a luscious gravy that clings to the shredded beef.
• 3 tablespoon butter (for gravy): Key to making the flour paste smooth and flavorful.

How to Make Instant Pot Mississippi Pot Roast Recipe

Step 1: Sear the Meat

Start by turning your Instant Pot onto sauté mode and adding the vegetable oil. When the oil is nice and hot, place your chuck roast pieces in one layer. Let them sear without moving for about 5 minutes to develop a gorgeous golden crust, then flip and sear the other side. This step is crucial for locking in juices and building deep flavor that shines through in the final dish.

Step 2: Sauté Onion and Deglaze

Remove the browned roast to a plate and add the diced onion to the pot. Pour in just enough beef broth to cover the bottom, and use a wooden spoon to scrape up all those flavorful browned bits stuck to the pot. This deglazing step captures every bit of flavor so none goes to waste.

Step 3: Add the Flavorful Liquids and Seasonings

Next, toss in your pepperoncini peppers, pepperoncini juice, the remaining beef broth, ranch dressing mix, au jus seasoning, and butter into the Instant Pot. Give it a good stir so everything starts to meld into a rich, tangy base. This combination is what gives the Mississippi Pot Roast its signature bold, comforting flavor.

Step 4: Pressure Cook the Roast

Turn off the sauté mode, nestle the seared meat chunks back into the pot, and seal the Instant Pot lid. Set it to pressure cook on high for 1 hour. After cooking, allow the pressure to release naturally for 15 minutes before manually releasing any remaining pressure. This slow release ensures the meat stays juicy and perfectly tender.

Step 5: Shred the Meat and Thicken the Sauce

Carefully remove the roast pieces and shred them with two forks — the meat will fall apart effortlessly! Then, turn the sauté function on again. While waiting for the pot to heat, mix the flour and butter together to create a paste. Stir this mixture into the hot cooking liquid, and watch as it thickens into a luscious gravy that beautifully coats every tender shred of beef.

How to Serve Instant Pot Mississippi Pot Roast Recipe

Garnishes

A sprinkle of freshly chopped parsley adds a pop of vibrant color and a hint of freshness that perfectly balances the rich, buttery flavors. For a little extra tang, you can also add sliced pepperoncini on top, echoing the zesty heat within the dish.

Side Dishes

This pot roast is hearty and flavorful enough to stand on its own, but pairing it with creamy mashed potatoes or buttery dinner rolls takes the meal to an entirely new level of comfort. Roasted vegetables or a crisp green salad bring a wonderful contrast of textures and brightness to the plate.

Creative Ways to Present

Serve the shredded beef piled high over a bed of buttery egg noodles or creamy polenta for an elegant dinner twist. Another fun idea is to stuff the meat into warm sandwich buns for an indulgent roast beef sandwich, drizzled with extra gravy for that perfect, messy bite.

Make Ahead and Storage

Storing Leftovers

Leftover Mississippi Pot Roast keeps beautifully in an airtight container in the fridge for 3 to 4 days. The flavors actually deepen as it rests, making your next meal just as enjoyable, if not better.

Freezing

This Instant Pot Mississippi Pot Roast Recipe freezes exceptionally well. Portion the shredded beef and gravy into freezer-safe containers or bags for up to 3 months, so you can savor this comforting dish whenever the craving hits.

Reheating

Reheat leftovers gently on the stovetop or in the microwave, adding a splash of beef broth if the gravy has thickened too much. Warm it through until steaming, and you’ll get that just-cooked flavor all over again.

FAQs

Can I use a different cut of beef for this recipe?

Chuck roast is ideal because it becomes tender and flavorful with pressure cooking, but you can also use brisket or rump roast. Just keep in mind that cooking times might vary slightly depending on the cut’s thickness and fat content.

What if I don’t have pepperoncini available?

Pepperoncini add a unique tangy heat, but if you can’t find them, banana peppers with a splash of vinegar can be a decent substitute. The flavor won’t be exactly the same, but it will still add that welcome zing.

Can I make this recipe without the Instant Pot?

Absolutely! While this recipe shines with the speed and convenience of the Instant Pot, you can slow cook the roast on low heat for 6 to 8 hours until tender, adjusting liquid levels as needed.

How thick should I make the gravy?

For the perfect consistency, aim for a gravy thick enough to coat the back of a spoon but still pourable. If it’s too thick, whisk in a bit more beef broth to loosen it up.

Is this recipe spicy?

Thanks to the pepperoncini, the dish has a mild tangy heat that adds dimension without being overpowering. If you prefer spicier food, you could add a pinch of crushed red pepper flakes or hot sauce to suit your taste.
