I think a Mississippi Roast is probably something everybody has made by now and might even know it by another name. I made one this last week though and used it a few different ways that all came out really good. Took a chuck roast and seasoned it with salt and pepper and let it sit overnight. In the AM I sliced an onion, layered them across a crock pot, and set the roast on top of the onions. Then I emptied a packet of Ranch seasoning and a package of Au Jus over the roast and onions. Then take a full jar of pepperoncini peppers and the juice and dump over the top. Lastly add 1/2 a stick of butter right on top of the roast and cook it on low 8-10 hours.
That's the standard recipe that most make and the only thing I did different was to add a little bit of chicken broth to mine. I do that because the first thing I made out of this was French Dip sandwiches and I wanted that extra broth for cups of Au Jus. It makes killer sandwiches with a loaf of crusty French bread and some provolone. The next thing I made was poutine which I had never had before. It was fantastic. Air fried some fries, added a bag of cheese curds, a big pile of the roast chopped up, layered everything up, and made a brown gravy to pour over the top. Decadent and a fantastic comfort food. Lastly I used the small remaining roast to make a breakfast hash with eggs, potatoes, onions, and peppers.
I love using big pieces of meat like this for multiple dishes throughout the week. It makes me more creative in the kitchen to know I need to come up with a way to eat a roast, brisket, pork shoulder or whatever for for days and keep it from getting boring.
