How Much Food for a Brunch for a Crowd?

By Diwakar Patel · Updated August 2026

Quick answer: For a seated brunch, plan per person: 2 large eggs, 3 regular-cut bacon slices (about 3 oz / 85 g raw), 1 pastry, ½ cup (120 ml) fruit, 6 fl oz (180 ml) juice and 12–16 fl oz (350–475 ml) coffee. For a buffet, add 25% to bacon and pastries.

Two eggs, three slices of bacon, one pastry, half a cup of fruit. That is the whole answer for a seated brunch, and every other number on this page is an adjustment to it.

Those aren't invented. They're what Ellen's Kitchen — a long-running, non-commercial quantity-cooking reference — specifies for breakfast for 100: 16–18 dozen eggs, 18 pounds of thin-sliced bacon at three slices per person, and 9 dozen large pastries. Do the division and it lands exactly where the table above does.

The trouble starts the moment anyone tries to buy it.

Bacon: the number that changes meaning between two sentences

Brunch advice switches units mid-paragraph, and bacon is where it does the most damage. Half the sources count slices (two or three per head). The other half quote pounds (a quarter to a half per head). Converting between them requires a number almost nobody states: how many slices are in a pound.

There is no single answer, and that is the finding. USDA's Institutional Meat Purchase Specifications, Series 500 — the federal buying spec for sliced bacon — doesn't fix a count at all. For center-cut sliced bacon (Item No. 538A) it offers the buyer a menu: "12–14; 14–18; 18–22; 22–26; 26–30; 28–32: or as specified." A pound of bacon can legitimately be twelve slices or thirty-two. In practice retail and foodservice cluster near the fat end of that range — Wright Brand's regular sliced bacon is specified at 14–18 slices per pound, and its thick sliced at 10–14.

So "half a pound of bacon per person" is five slices or sixteen depending on a cut choice the writer never made. That is a threefold swing hiding inside a figure that looks precise.

Then there is the second unit switch, which is worse. Bacon loses about 70% of its weight in the pan. The USDA Table of Cooking Yields for Meat and Poultry gives cured pork bacon a yield of 31% pan-fried, 32% baked and 29% microwaved. A quarter-pound of raw bacon per person is about 1¼ oz (35 g) on the plate. Half a pound is 2½ oz (70 g). If a figure doesn't say raw or cooked, assume raw — nobody buys bacon by its cooked weight — but check, because catering yield sheets often don't.

The per-person chart

Seated brunch, one plate per guest, no returns to a buffet.

Serve bacon and sausage and you don't double the meat — split it, roughly two bacon slices plus one link each, and buy a little over half of each figure.

Eggs are counted, but sold by weight

"Two eggs per person" is the most stable number in brunch planning and also a quiet trap at scale, because an egg is not a fixed quantity. USDA's Standards, Grades, and Weight Classes for Shell Eggs sets minimum net weight per dozen: Large is 24 oz, Extra Large 27 oz, Jumbo 30 oz, Medium 21 oz.

That means Jumbo eggs are 25% more egg than Large, and Medium are 12.5% less. Buying "17 dozen eggs for 100 people" in Medium instead of Large short-changes the pan by more than two dozen eggs' worth of volume. When you're scaling, count in ounces of egg, not eggs. Ellen's Kitchen adds a good trick that has nothing to do with weight: hard-boil an extra dozen and fold them chopped through the scramble at the end. It stops the pan going watery over a long service.

Where the sources genuinely disagree: sausage

Bacon shrinkage is settled. Sausage isn't, and the gap is large enough to matter.

The USDA cooking-yield table gives fresh pork sausage a pan-fried yield of 80% — a 20% loss. Ellen's Kitchen, working from big-batch practice, budgets 24 lb of patties for 100 two-patty servings and states flatly that "it shrinks 50%."

We're not going to average those. They are probably measuring different things — the USDA figure is a controlled lab preparation of bulk fresh sausage, Ellen's is formed patties on a flat-top losing both fat and water at commercial heat — but neither says so, and there is no source that reconciles them. Practical read: buy against the pessimistic number. Sausage that shrinks less than expected is a plate of extra sausage; sausage that shrinks more is a queue.

Coffee and juice: the third unit problem

Coffee has its own version of the bacon disease. Ellen's quantity chart lists 1 lb of coffee to 3 gallons of water for 50 servings, which works out to a single 8 fl oz cup per head and about ⅓ oz (9 g) of grounds per cup. That is a canteen-breakfast figure. Brunch is not a canteen breakfast — people sit for two hours, and a brunch mug is 10–12 fl oz, not 8. Plan 12–16 fl oz per person and treat the chart figure as a floor. Our coffee calculator converts guests into grounds and water; the coffee for a crowd guide covers urns and holding times.

Juice splits by what it's for. Straight juice runs 4–6 fl oz a glass. Mimosas change the arithmetic completely, because the juice is now half a cocktail rather than a drink: a 750 ml bottle of sparkling wine wants 750 ml of orange juice and makes about ten mimosas, which our orange juice for mimosas guide works through in detail. The mimosa calculator does it by guest count.

Seated versus buffet

The multiplier is not the same for every dish, which is why blanket "add 20% for a buffet" advice over-buys fruit and under-buys bacon.

At a seated brunch the per-person figure is the portion — someone plates it. At a buffet guests serve themselves, take more of the hero items, and come back. Our read, and we're labelling it as a read rather than a sourced figure: add 25% to bacon, sausage and pastries; leave eggs, fruit and potatoes at the chart figure. The self-serve premium lands almost entirely on the items people feel they're being rationed on. Nothing on a brunch table is over-taken like bacon.

One buffet rule that is sourced: University of Minnesota Extension caps room-temperature food at two hours cumulative. Put out half of the eggs and bacon, hold the rest hot, and swap trays — which also stops the chafing dish looking picked-over an hour in.

By guest count

Seated brunch, at the per-person figures above.

Bacon poundage assumes regular cut at 16 slices to the pound. Buy thick cut and the same slice count costs you about 25 lb at 100 guests instead of 18. Coffee is brewed volume at 16 fl oz a head; 12½ gallons needs roughly 4 lb of grounds.

The caveat worth reading

The strongest figures here — the slice-count spec, the cooking yields, the egg weight classes — are all USDA, and they are conversion factors rather than portion advice. The government publishes how bacon behaves; it does not publish how much of it to give a guest.

For the per-head portions themselves, the honest position is that we found one substantial non-commercial source and used it. Ellen's Kitchen has been publishing big-batch quantities free for decades and has no product to sell, which makes it the best available anchor — but it is one source, and its figures are institutional line-service portions that skew lean. The per-person pound figures for bacon that circulate widely online (¼ to ½ lb) are 1.5–3× what Ellen's actually budgets, and we could not trace any of them to a source that isn't a recipe site or a retailer. Treat the low end of every range here as reliable and the top end as generosity, not as a requirement.

If your brunch is really a drinks event with food attached, how many appetizers per person covers the grazing half, and the party drink calculator sizes everything poured.

Next step: get the coffee right first — it's the item guests notice running out. Start with the coffee calculator, then work the food back from your headcount.
