A cool, creamy retro Watergate Salad bursting with pistachio, pineapple, mini marshmallows, and whipped topping. No baking, just 5 main ingredients, and perfect for potlucks and holidays.
Use instant pistachio pudding only—cook-and-serve will not thicken properly with pineapple juice. Do not skip the chill time; 2–4 hours in the fridge allows the marshmallows to soften and the flavors to blend. A small pinch of salt helps balance the sweetness and enhances the pistachio and pineapple flavors. Serve well-chilled, and refrigerate after 2 hours at room temperature for food safety. For potlucks, serve the salad in a clear glass bowl or trifle dish so the pale green color is visible.
