This is all you need:
1 Roast (I used a deer roast Jeremiah got from hunting last season)
2 pks. Onion Soup Mix
2 Cans Cream of Onion (or chicken, mushroom, celery..etc)
Spray your crock pot with cooking oil. Put the roast on the bottom. Cover it with 1 of the soup mix packets, then with one of the Cream of Onion. Dump the carrots and potatoes on top of that. Then put the other soup mix packets and Cream of Onion on top of them. Pour about 1 1/2 cups water over it all. Cook on Low for 8 hours or High for 6. It makes a delicious gravy.
It's so simple! And, it was perfect for this cold wet day.
