Sprinkle the surface of the chuck roast with salt and pepper on both sides.
Place the chuck roast into the bottom of a medium size crockpot. Set the crockpot on low
Sprinkle the Au Jus, Ranch Seasoning over the top of the roast.
Place the pepperoncini peppers, water, bay leaves and minced garlic in the crockpot too.
Place the lid on securely.
Allow to cook on low for at least 8 hours. After 8 hours you may remove the lid and using a fork, see if the roast is tender. If it is not falling apart (fork tender), place the lid back on and cook for another hour or more until it is fork tender and falling apart.
When falling apart, remove to a serving platter OR you may use a large slotted spoon to remove the meat from the crockpot directly onto plates. Do not serve/eat the Bay leaves. Some people really like to eat the peppers and the garlic cloves if you have used those. The juice left in the crock pot is used to make the gravy in the next step.
