Chuck or Shoulder Roast
A-1 Sauce
Family-Sized Cream of Chicken
Lipton's or Camptbell's Onion Soup Mix
Not sure whether this would be considered pot roast or not but we make it all the time and it is one of the things that we make for other families when someone is sick or there has been a bereavement because it is easy and travels well. If you want to do the pot roast vegetables, I am sure they would cook well just by using a bit more foil and including them in with the roast.
Use chuck or shoulder roast (original recipe was chuck roast and accidentally discovered when there was nothing at the store but shoulder that it was even better). Purchase the long heavy duty tin foil and pull off about a foot and a half so there is enough to roll down before you put it in the oven. Place the foil in any type of casserole dish that is big enough to accomodate the roast. Put the roast on the foil and sprinkle 1-2 T of A-1 and about a half package of the Lipton's or Campbell's French Onion Soup Mix. A Family-sized can of cream of chicken soup (original recipe called for cream of mushroom, again when I had nothing else, used the chicken and it is better) spooned over that.
Put the long ends of the foil together and roll it down, crimp the sides upward and roll those. Leave a little room so that when things get steamy the sauce is not fighting to get out of the foil. If you manage to do this right not only do you have the gravy, you have no mess because you just lift the foil out of the pan and you're done. Most of the time there is some minimal leakage but we're working on it.
Cook at 350 for about 2-3 hours. The longer you cook it, the more tender it gets. We usually judge cooking time by leakage and the way the gravy smells/sounds, sorry not more precise on that one. We often make two of them and leave one wrapped up in the foil to eat a day or two later. Watch it getting the foil open, steam can burn the heck out of you. It is easiest to just remove the roast to a plate and get the gravy transferred from the foil to a bowl.
We usually serve with mashed potatoes. Boil the potatoes, while mashing add sour cream and cream cheese to taste. Big pot 16 oz container of sour cream and whole package of cream cheese. We usually don't need butter or milk but add them if the potatoes are at all lumpy.
