This from-scratch green bean casserole skips the canned soup for a quick olive oil mushroom sauce and a crown of shatter-crisp fried shallots. Siracusana Zaituna, one of Tenuta Cavasecca's rarest cultivars from the hills around Noto, brings a robust, green-gold finish that holds its own against the dish's richness.
