Put one roast in a 6 qt crock pot then sprinkle with dry onion soup mix. Top with one onion quartered, carrots, and potatoes. Cook on high 6 hours our until meat is completely cooked.
I mash my carrots with a fork and put butter on them, mash potatoes with a fork and put sour cream on them, and put salt and pepper on everything! That is the best way to eat this roast...just like my Mama!
