This Mississippi Pot Roast is the easiest, most flavorful dinner you’ll make all week! Just throw everything into the Slow Cooker and let it cook low and slow until the beef is tender and falling apart.
Place sliced onions at the bottom of the slow cooker.
Put the chuck roast on top of the onions.
In a small bowl, mix Worcestershire sauce, soy sauce, onion powder, garlic powder, thyme, pepper, and paprika.
Rub this mixture all over the roast.
Sprinkle the ranch dressing mix over the roast.
Place the butter on top of the roast.
Add pepperoncini peppers and pour pepperoncini juice and beef broth around the roast.
For slow cooker: Cover and cook on low for 8 hours or on high for 4-5 hours. For pressure cooker: Cook on high pressure for 60 minutes, then natural release for 15 minutes.
Once done, shred the meat in the pot, mixing it with the juices.
If you prefer a thicker sauce, mix 2 tablespoons cornstarch with a little cold water, then stir into the pot. Cook on high for an additional 15-20 minutes until thickened.
Notes
To Cook in an Instant Pot: Follow the same directions as the slow cooker version, but cook in the Instant Pot on High Pressure for 45-50 minutes, followed by a natural release for 15 minutes. Cook until the roast is tender and can shred easily.
