After mentioning Ro-Tel in an interview, Lady Bird Johnson is credited with putting the canned tomato brand on the U.S. map in the early 1960s. The former first lady was known to use Ro-Tel in a few recipes, including her King Ranch Casserole. This simple dish, which serves six, comes from Johnson’s recipe archives at the LBJ Library and Museum in Austin.
King Ranch Casserole
1/4 cup margarine
1 large onion, chopped
1 10 oz. can Ro-Tel tomatoes
1 10.5 oz. can cream of chicken soup
1 10.5 oz. can cream of mushroom soup
