Put all the ingredients into the crock pot and cook on low for at least 9 hours. I made a small roast as there is just the two of us, but you can use any size. The larger the longer you want it to cook. I cooked the small one for 9 hours. The key is the longer you cook it the better. It was just delicious. If the gravy is to thin you can thicken it up with wondra or corn starch. I served the roast with mashed potatoes.
This is just a great recipe and requires few ingredients.
