Food at a graduation party

  • Graduation parties often span 4+ hours - plan for grazing, not a sit-down meal.
  • Young adults eat more than you would expect, so add a margin to your calculations for that age group.
  • Set up a separate kids' food station with pizza and sliders to keep parents happy.
  • Outdoor graduation parties need food that won't spoil - keep hot foods hot and cold foods cold.
  • Photo ops happen constantly - finger foods beat anything requiring utensils.

Graduation parties are grazing events. Finger foods work best - pizza slices, sliders, wings, and appetizers that guests can grab while mingling. If your graduate is 21+, expect their friends to eat AND drink more than the older guests.
