A simple, flavorful Mississippi pot roast made with just four ingredients in a slow cooker, yielding tender, juicy meat with a rich, buttery, peppery sauce.
Do not skip the butter as it creates a rich, silky sauce. Resist overcooking beyond 9 hours on low to avoid drying out the roast. No need to brown the roast before cooking. Use fresh pepperoncini juice for best flavor. Let the roast rest 10 minutes before slicing. Save leftover sauce for dipping or reheating.
