Mississippi Pot Roast
Mississippi pot roast is the recipe the internet decided was perfect: a chuck roast, two seasoning packets, a block of butter and a handful of pepperoncini, all left to sort themselves out in the crock pot. And fair play — it works. But your granny never bought a packet of anything in her life, so this version gives you both roads: the classic packet recipe exactly as it should be, and her from-scratch swap for the ranch and the au jus, made from things already in your cupboard.
Now, the butter. The famous version calls for a whole 115 g block sitting on top like a trophy. We use 60 g, and here is the honest reason: a chuck roast renders plenty of its own fat over eight hours, and most of that extra butter ends up as a slick you skim off and pour away. Sixty grams gives the gravy all the silk it needs without the grease. Granny did not waste butter, and neither will you.
One more thing that matters: no water, no stock. A slow cooker barely loses a drop of liquid, and the beef makes its own juices as it goes. The splash of pepperoncini brine is all the help it needs. Add more and you will be ladling soup over your mash instead of gravy.

Ingredients
Tick each one off as you go.
- FOR THE POT ROAST
- 1.6 kg beef chuck roast (about 3 1/2 lb)
- 1 tbsp neutral oil, for browning
- 1 packet (28 g) ranch seasoning mix, or the from-scratch swap below
- 1 packet (28 g) au jus gravy mix, or the from-scratch swap below
- 60 g butter, in one piece
- 8 pepperoncini peppers, left whole
- 60 ml pepperoncini brine, straight from the jar
- 1 tbsp cornflour (cornstarch), optional, for a proper gravy
- Black pepper, to taste (the packets bring salt enough)
- FOR GRANNY'S FROM-SCRATCH PACKET SWAP (OPTIONAL)
- 2 tbsp buttermilk powder
- 1 tsp each dried dill and dried parsley
- 1 tsp each garlic powder and onion powder
- 2 beef stock cubes, crumbled fine
- 1 tsp Worcestershire sauce
Method
- Brown. Pat the roast dry and give it a good grind of black pepper — no salt, the seasonings carry plenty. Heat the oil in a heavy pan over high heat and brown the roast hard, 3 to 4 minutes a side. You can tip it in raw and it will still cook safely, but that dark crust is where the flavour lives, and eight minutes now pays you back all day.
- Mix. Using the packets? Skip along to the next step. Making granny's swap: stir the buttermilk powder, dill, parsley, garlic powder and onion powder together in a cup — that is your ranch. In another, work the crumbled stock cubes into the Worcestershire sauce with a grind of pepper — that is your au jus, without paying for the envelope.
- Load. Set the roast in the slow cooker. Sprinkle both seasonings over the top, sit the butter in the middle, and tuck the pepperoncini around the sides. Pour the brine down the side of the pot, not over the meat. No water and no stock — the cooker keeps every drop, and the beef makes its own juices.
- Cook. Lid on. Low for 8 to 9 hours. Not High — a cheap cut needs the long, slow haul for the collagen to melt into silk. And leave that lid alone: every peek lets the heat out and adds 20 to 30 minutes. Trust your nose, not your eyes.
- Shred. The roast is ready when a fork twists through it with no argument. Lift it onto a board, pull it into fat shreds, and throw away the seam of fat. If there is a shiny layer of grease on the juices, skim off what you do not want, then return the meat to the pot.
- Thicken. For a gravy that clings, push the meat to one side. Stir the cornflour into 2 tablespoons of cold water, then stir the slurry through the juices. Lid off, High, 15 to 20 minutes until it coats the back of a spoon. Serve over mash, rice or split soft rolls, with the peppers on top for the brave.
Buy pepperoncini, not banana peppers — the jars look near identical on the shelf, but pepperoncini bring the gentle vinegar tang this roast is famous for. And keep the rest of the brine: a splash stirred into the finished gravy wakes the whole pot up.
Tips for a melt-apart roast
No water. None.
A slow cooker barely evaporates a thing, so the 60 ml of brine is all the liquid this roast needs. The chuck will make its own juices within the first hour. Add stock or water on top of that and you get a thin, grey gravy that tastes of nothing.
Brown it if you can
Raw meat is perfectly safe in a slow cooker, so skip the searing on a mad morning. But browning builds the deep, roasty base the packets alone cannot give you. If you sear, splash a little water in the hot pan afterwards and scrape the brown bits into the cooker too.
Keep the lid down
Every time you lift the lid, the heat tumbles out and the roast owes you another 20 to 30 minutes. There is nothing to stir and nothing to check until the 8-hour mark, when the fork will tell you everything you need to know.
Questions, answered
Is Mississippi pot roast spicy?
No — pepperoncini are mild, tangy little things, more vinegar than fire, and the long cook mellows them further. The gravy comes out savoury with a gentle zip. For very cautious eaters use 4 or 5 peppers instead of 8; for tang lovers, add an extra splash of brine at the end.
Can I cook Mississippi pot roast on High?
You can, at roughly 4 and a half to 5 hours, but we do not recommend it. Chuck is full of collagen that needs the long, low haul to melt properly — Low for 8 to 9 hours gives you spoon-tender shreds, while High risks meat that is technically cooked but still chewy.
Can I put a frozen roast straight in the crock pot?
No. A whole frozen roast spends far too long in the temperature danger zone before it heats through, and that is not safe in a slow cooker. Thaw it completely in the fridge first — allow a full day or two for a roast this size — then carry on as written.
How do I make Mississippi pot roast in an Instant Pot?
Brown the roast on Sauté, then deglaze thoroughly with 250 ml (1 cup) beef stock — the pot needs that much thin liquid to come to pressure, and any stuck-on bits trigger the burn error. Cut the roast into two pieces so it cooks evenly, add the seasonings, butter, peppers and brine, and cook 60 to 75 minutes on high pressure with a 15-minute natural release. Thicken with the cornflour slurry on Sauté afterwards, never before.
Why only 60 g of butter when every other recipe uses a whole stick?
Because we counted what actually happens to it. Chuck renders a good deal of its own fat over 8 hours, and most of a full 115 g block simply floats on top as grease you skim off and bin. Sixty grams gives the gravy its shine and silkiness without the waste — granny would call the rest showing off.
