This Mississippi Pot Roast turns a plain chuck roast into fork-tender beef sitting in a glossy, buttery gravy with a gentle tang, using just five main ingredients and no added water or broth.
1tbspolive oil - 15 ml; optional, only needed if searing the roast
Instructions
Pat the chuck roast dry all over with paper towels and season lightly with black pepper on both sides. Skip the salt for now.
Heat olive oil in a cast iron skillet over medium-high heat and sear the roast 3 to 4 minutes per side until deeply browned. Transfer to the slow cooker, or skip searing and place the raw roast straight into the pot.
Sprinkle the entire packet of ranch dressing mix evenly over the roast, followed by the full packet of au jus gravy mix. No need to rub them in.
Place the whole stick of butter on top of the roast, scatter the pepperoncini around and over the beef, and pour in 2 tbsp of the pepperoncini brine. Do not add any water or broth.
Cover and cook on low for 8 hours, or on high for 4 to 5 hours if short on time. Resist lifting the lid.
The roast is ready when it shreds with almost no resistance and reaches an internal temperature of 200 to 205°F (93 to 96°C). If still firm, cook another 30 to 60 minutes.
Lift the roast onto a cutting board and shred with two forks or meat claws. Return the shredded beef to the pot, stir through the gravy, taste, and add salt only if needed.
Notes
Skip the added liquid. The butter, brine, and beef juices are all the moisture this roast needs, so pouring in broth or water only dilutes the gravy.
Choose chuck over leaner cuts. The marbling in a chuck roast is what turns tender, while leaner cuts like rump or sirloin tip can end up dry and stringy.
Use unsalted butter. Both seasoning packets and the brine bring plenty of sodium, so unsalted butter gives you control over the final saltiness.
Do not skip the brine. That splash of pepperoncini juice adds a tang you cannot get from the peppers alone.
Cook on low when you can. High heat works in a pinch, but low heat gives the collagen time to melt for a silkier texture.
Adjust the heat level. For a milder roast use fewer peppers, and for more kick add a couple extra or a few sliced ones.
Let it rest in the gravy. Stirring the shredded beef back into the sauce for 10 minutes lets it drink up the flavor.
Storage: Cool the beef and gravy, then store together in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months.
Reheating: Warm gently in a covered pan over low heat or in the microwave in 60-second bursts, always with the gravy to keep the beef moist.
Repurpose leftovers: Pile the shredded beef onto rolls for sliders, fold it into tacos, or spoon it over baked potatoes.
