How Much Food Per Person? Catering Portion Planning

5 min read

Portion planning is where catering profit is actually decided — order too much and you donate the margin to the compost bin, too little and the host remembers forever. These are working numbers per adult guest; scale confidence with your own returned-pan data.

Mains

Plated protein: 6–8 oz cooked
Buffet protein, single option: 8–10 oz (guests self-portion generously)
Buffet with two proteins: 5–6 oz each — most guests take both
Pasta as a main: 5–6 oz dry equivalent

Sides, salads, bread

Starch: 4–5 oz
Vegetable: 3–4 oz
Composed salad: 2–3 oz dressed
Bread: 1.5 pieces (order 2 — it's cheap insurance)

Reception mode

Passed apps before a meal: 4–6 pieces per guest per hour
Apps as the meal: 10–14 pieces per guest across the event
Cheese/grazing display: 2–3 oz per guest as an accent, 4–5 as a course
Dessert: 1 plated portion, or 1.5–2 small bites per guest

The multipliers that save you

Overage: cook 5–10% above the guaranteed count (see event food cost). Demographics: a college athletics banquet eats 1.5× a retirement luncheon; daytime corporate eats ~20% lighter than evening social. Open bar: add 10–15% to late-night food.

Worked example: 50-guest buffet

Two proteins (chicken thighs + brisket): 50 × 6 oz × 2 = 37.5 lb cooked — at ~60% cook yield that's 62 lb raw. Starch: 50 × 5 oz ≈ 16 lb. Vegetable: 50 × 4 oz ≈ 12.5 lb. Salad 9 lb dressed, bread 100 pieces, dessert bites 85. Add 8% overage to the proteins, cost every line at yield-adjusted prices, and your quote stands on arithmetic instead of vibes.

Freecost costs each buffet item as a recipe with real yields, so “62 lb raw brisket” carries its true dollar figure into the quote automatically.
