Mississippi Pot Roast has become a beloved staple in American households, offering rich flavors and fall-apart tender meat that satisfies those cool-weather cravings perfectly.

This revolutionary kitchen tool lets you create that same mouthwatering, tender Mississippi Pot Roast in a fraction of the time, making it possible to enjoy this ultimate comfort food even on your busiest weeknights. Whether you’re new to pressure cooking or already an Instant Pot enthusiast, this recipe delivers all the rich, tangy, savory goodness of traditional Mississippi Pot Roast without the long wait. Let’s dive into how you can create this fall favorite with minimal effort and maximum flavor.

What Is Mississippi Pot Roast?

Despite its name suggesting deep Southern roots going back generations, Mississippi Pot Roast is actually a relatively modern creation. The dish was created by Robin Chapman of Ripley, Mississippi, in the early 2000s as an adaptation of a roast recipe shared by her aunt. Chapman modified the original recipe to be less spicy for her children, and what resulted was a perfect balance of flavors that would soon take the internet—and American kitchens—by storm.

The signature taste of Mississippi Pot Roast comes from its unique combination of ingredients: tender beef chuck roast infused with tangy ranch seasoning, savory au jus gravy mix, zesty pepperoncini peppers, and rich butter. This blend creates a harmonious balance of flavors—savory, tangy, slightly spicy, and wonderfully rich—that transforms an ordinary pot roast into something truly extraordinary. The meat becomes fork-tender, absorbing all those complex flavors while creating its own mouthwatering gravy.

What makes this dish particularly perfect for fall is not just its warm, comforting nature, but also its versatility. As autumn schedules fill with school activities, sports, and holiday preparations, having a reliable, delicious meal that practically cooks itself becomes invaluable. The robust flavors pair beautifully with classic fall vegetables and starches, creating a complete meal that feels like the culinary equivalent of a cozy sweater on a crisp autumn day.

Why Make Mississippi Pot Roast Instant Pot?

The traditional method of preparing Mississippi Pot Roast calls for 8-10 hours in a slow cooker, which requires planning ahead and starting your meal preparation early in the morning. While delicious, this timeline doesn’t always align with our busy, often unpredictable schedules. Enter the Instant Pot—a game-changer for time-pressed home cooks everywhere.

Using the Instant Pot reduces cooking time dramatically, transforming what was once an all-day affair into a weeknight-friendly meal that’s ready in about 90 minutes total. The pressure cooking method not only speeds up the process but actually helps to intensify flavors while breaking down the tough muscle fibers in chuck roast more efficiently. The result? A pot roast that’s every bit as tender and flavorful as its slow-cooked counterpart, ready in a fraction of the time.

Beyond time savings, the Instant Pot simplifies the entire cooking process. Its sauté function allows you to brown the meat right in the same pot where it will cook, eliminating extra dishes and capturing all those flavorful browned bits. The sealed pressure environment means less liquid evaporation, resulting in a naturally more concentrated flavor and juicier meat. And perhaps most appealing of all is the “set it and forget it” nature—once everything is in the pot and you’ve set the timer, you’re free to help with homework, fold laundry, or simply relax until dinner is ready.

Ingredients You’ll Need for Mississippi Pot Roast Instant Pot

To create this delicious comfort meal, you’ll need just a handful of ingredients:

• 3-4 pound chuck roast (look for one with good marbling for the best flavor and tenderness)
• 1 packet (1 oz) ranch seasoning mix
• 1 packet (1 oz) au jus gravy mix
• 6-8 pepperoncini peppers, plus 2-3 tablespoons of the brine from the jar
• 1/2 cup butter (1 stick), cut into tablespoon-sized pieces
• 2 cloves garlic, minced (optional but recommended)
• 1 small onion, quartered (optional)
• 1 cup beef broth or water
• 2 tablespoons olive oil (for browning)
• Salt and pepper to taste

These simple ingredients work together to create layers of flavor that make this dish truly special. The best part? Most of these items are pantry staples that you might already have on hand.

Mississippi Pot Roast Instant Pot: Step-by-Step Instructions

Prep the Ingredients

1. Season the meat: Remove the chuck roast from the refrigerator about 30 minutes before cooking to take the chill off. Pat the meat dry with paper towels, then season generously with salt and pepper on all sides. This initial seasoning provides a flavor foundation for your roast.
2. Prepare your add-ins: Slice or mince the garlic if using, quarter the onion, and gather your pepperoncini peppers. Open the seasoning packets and have them ready to go. Cut your butter into tablespoon-sized pieces for even distribution during cooking.

Instant Pot Steps

1. Brown the meat: Set your Instant Pot to Sauté mode and add the olive oil. Once hot, add the seasoned chuck roast and brown for 3-4 minutes on each side until you get a nice caramelized crust. This step is crucial for developing depth of flavor in the final dish.
2. Add the flavor builders: Once the meat is browned, turn off the Sauté function. Sprinkle the ranch seasoning and au jus mix evenly over the top of the roast. Place the butter pieces around the roast, then arrange the pepperoncini peppers on and around the meat. If using, add the garlic and onion quarters around the sides.
3. Add liquid: Pour in the beef broth or water and 2-3 tablespoons of pepperoncini brine. The liquid should come about 1/3 of the way up the sides of the roast – not completely covering it.
4. Pressure cook: Close the Instant Pot lid, set the valve to the sealing position, and program it to cook on high pressure. For a 3-pound roast, set the timer for 60 minutes. For a 4-pound roast, increase to 70 minutes. For an extra-tender result that falls apart easily, add 10 more minutes to either cooking time.
5. Natural release: Once the cooking time is complete, allow the pressure to release naturally for 15-20 minutes before carefully turning the valve to venting to release any remaining pressure.
6. Finish and shred: Open the lid away from your face to avoid the hot steam. The roast should be fork-tender and easy to shred. You can either remove it to a serving platter and shred it there, or shred it directly in the pot, allowing the meat to soak up more of that flavorful liquid.

Key Tips

• Cut size matters: If your roast is too large to fit comfortably in your Instant Pot, cut it into 2-3 large chunks. This will help it cook more evenly and may reduce your cooking time slightly.
• Don’t skip browning: While you might be tempted to save time by skipping the browning step, those few extra minutes create significant flavor development through the Maillard reaction.
• Less liquid is more: One common mistake with Instant Pot cooking is adding too much liquid. Unlike slow cookers, pressure cookers create a sealed environment where very little evaporation occurs. The cup of liquid called for in this recipe is sufficient for creating steam and pressure.
• Customize the heat: If you enjoy more heat, add additional pepperoncini peppers or include a few tablespoons of the brine from the jar for extra tanginess.

FAQ About Mississippi Pot Roast Instant Pot

Can I use a different cut of beef?

While chuck roast is ideal for its marbling and how it breaks down during pressure cooking, you can substitute other cuts. Bottom round, brisket, or shoulder roast will all work, though the texture and fat content will vary slightly. If using a leaner cut like bottom round, consider adding a bit more butter to compensate for the reduced fat content. Cooking times may also need slight adjustments—leaner cuts might require 5-10 minutes less cooking time, while tougher cuts could need a few minutes more.

Can I freeze leftovers?

Absolutely! Mississippi Pot Roast freezes beautifully. Allow the leftovers to cool completely, then portion them into airtight containers or heavy-duty freezer bags, making sure to include some of the gravy to keep the meat moist. Properly stored, it will maintain good quality for up to 3 months. To reheat, thaw overnight in the refrigerator, then warm gently in a covered saucepan over low heat or in the microwave at 50% power, stirring occasionally.

Can I adjust the spice level?

Yes, the heat level is easily customizable. For a milder version, reduce the number of pepperoncini peppers and omit the brine. For more heat, add more peppers, include some of the seeds, or add a pinch of red pepper flakes. You can also experiment with different brands of pepperoncini, as some are naturally spicier than others. Remember that the peppers become milder as they cook, infusing the dish with flavor rather than intense heat.

How do I know if my roast is done?

The perfect Mississippi Pot Roast should be fork-tender, meaning you can easily pull it apart with minimal resistance using just a fork. If your roast isn’t quite there after the recommended cooking time, you can reseal the Instant Pot and cook for an additional 10-15 minutes. Different cuts and sizes of meat, as well as variations in individual Instant Pots, can affect cooking times, so let tenderness be your guide rather than strictly following the clock.
