This has become my go-to roast recipe.  With a short ingredient list, it is super cheap and makes a ton, so there are always a lot of leftovers. It tastes pretty great too.

• 1 packet McCormick’s Au Jus seasoning
• 1 packet Hidden Valley Ranch dressing mix
• 1 stick salted butter
• 3-4 lb chuck roast

Line your crock pot with foil and lay the roast in the bottom.  Sprinkle the seasoning packets over the roast and place the stick of butter on top.  Cook on low for 8 hrs.
