This is one of my favorite recipes
1 3- 5 # Chuck roast (frozen)
2 packages onion soup mix - dry
Pull off enough heavy duty foil to fold it into three layers that will be long enough when layered to wrap the roast.
In the center of the foil, sprinkle one package of the dry soup mix, place roast on top and sprinkle the additional soup mix on top of the roast. Wrap meat in the heavy duty foil (doubled). Place in baking pan with sides and put in oven at 225 or 250 early in the day. Roast will be done in the evening. Before serving, poke a hole in foil and pour off juices for gravy or just serve with the juice. Always tender and delish!!! The meat will fall off the bone.
