This is my most requested recipe. “Olympia” style is a layered dish. Usually with onions on the bottom (I prefer mine with spinach), then fish, next is a creamy layer of equal parts mayo and sour cream, then it’s topped off with a crispy element (bread crumbs, panko, or Ritz). Growing up, this dish was a staple at our family gatherings. It’s traditionally made with halibut, but really, any fish will do.
