Pasta salad quantities for a crowd
A dependable side-dish portion is 4 ounces of finished pasta salad per adult. For 100 people, that is 25 pounds. If several filling sides share the table, 3 ounces each may be enough; if pasta salad is the only substantial side, allow 5 to 6 ounces. For a main course with vegetables, cheese, beans, or meat mixed in, use 6 to 8 ounces per guest.
Finished weight includes cooked pasta, dressing, vegetables, and add-ins. Dry pasta roughly doubles in weight when cooked, but recipes vary, so calculate from your recipe yield whenever possible. A typical 25-pound side batch starts with about 10 to 12 pounds of dry pasta, then gains weight from dressing and mix-ins.
Buying, preparing, and serving
Round purchases up to full package sizes and keep a small reserve separate from the first buffet pan. Prepare the pasta one day ahead, cool it quickly, and add some dressing after chilling because pasta absorbs moisture. Crisp herbs, delicate greens, and crunchy toppings are best added shortly before service.
Keep cold pasta salad at 40 F (4 C) or below until serving. Put out smaller trays and replace them instead of leaving the entire batch at room temperature. Increase the estimate by roughly 10 percent for a long event, a mostly adult crowd, or self-service with large plates; reduce it when many other sides are offered.
