Brisket for 10 to 100 guests
Standard scenario: adults, average appetites, two or three sides on the table. The "at the counter" column rounds up to pieces you can actually buy.
| Guests | Cooked meat | Raw to buy | At the counter |
|---|---|---|---|
| 10 | 3.5 lb | 6.5–7.5 lb | one ~10-lb packer brisket (≈10 lb) |
| 20 | 6.5 lb | 13–14.5 lb | one ~15-lb packer brisket (≈15 lb) |
| 25 | 8.5 lb | 16.5–18.5 lb | two ~10-lb packer briskets (≈20 lb) |
| 50 | 16.5 lb | 33–37 lb | three ~12.5-lb packer briskets (≈38 lb) |
| 100 | 33 lb | 66–73 lb | five ~15-lb packer briskets (≈75 lb) |
The yield: raw pound ≠ served pound
A whole packer brisket loses roughly half its raw weight before it hits the board: a pound or three of hard fat comes off in the trim, then the long cook renders and evaporates a third or more of what goes on the smoker. Plan on about 45–50% of raw weight ending up as sliceable meat.
Buying brisket: what to look for
Buy the whole packer (point + flat together) — it is far cheaper per pound than a trimmed flat and the point makes burnt ends. Look for a flexible brisket with a thick, even flat; avoid ones where the flat tapers to a thin flag that will dry out. Flats alone run smaller (4–6 lb) and less forgiving. Choice grade is the sweet spot; Prime if the price is close.
Frequently asked questions
How much brisket per person?
⅓ lb of cooked brisket per adult when two or three sides share the table, ½ lb for hearty appetites or a meat-centered meal; kids about half. Since brisket keeps only 45–50% of its raw weight, that's roughly 0.66–0.73 lb raw per adult.
How much brisket for 20 people?
About 13–14.5 lb raw for 20 adults with a normal spread of sides — at the counter, one ~15-lb packer brisket (≈15 lb). Scale with the chart above or the calculator for your exact crowd.
Why buy so much more raw brisket than you serve?
A whole packer brisket loses roughly half its raw weight before it hits the board: a pound or three of hard fat comes off in the trim, then the long cook renders and evaporates a third or more of what goes on the smoker. Plan on about 45–50% of raw weight ending up as sliceable meat.
What internal temperature is brisket safe at?
Whole-muscle beef is safe at 145°F with a 3-minute rest — but safe is not the same as tender. Doneness details and hour-per-pound charts are on the brisket cook-time page.
Packer, point, or flat — which should I buy?
The whole packer. The flat slices, the point makes burnt ends, and per pound it costs much less than buying either muscle alone. Only go flat-only if your smoker genuinely cannot fit a packer.
Is 145°F really safe for brisket?
Yes — USDA calls whole-muscle beef safe at 145°F with a 3-minute rest. Brisket goes to 200°F+ for tenderness, not safety: the extra hours melt collagen into gelatin. Undercooked-but-safe brisket is chewy, not dangerous.
