This is what I do:
Marinade a beef roast in Lawry's Mesquite marinades.
Poke hole push garlic thru
then marinade for a few hours.
Then roast in oven. For a couple of hours.
Place potatoes, carrots and onions around the roast in the pan. Little water in pan to prevent burning.
Good stuff lawry's marinades.
Merry Christmas
