16 lb Brisket at 275°F

Wrapped in butcher paper, a 16 lb whole packer at 275°F runs about 13 h 25 m of cook time — plan 15 h 25 m door to table with a 2-hour rest. For dinner at 5 PM, put it on at 1:30 AM. Adjust anything below and the plan recalculates.

Planning estimates at ±12% — thickness matters more than weight, and no two briskets cook alike. The clock never decides when it's done: brisket is done when a probe slides into the thickest part of the flat like warm butter, around 203°F internal. Cook to feel, serve on time by resting longer — a wrapped brisket holds beautifully for hours.

Butcher paper wrap, whole packer, 2-hour rest. Start times round down to the quarter hour — early is free, late is dinner at nine.

Wrapped or naked at 275°F?

Wrapping shortens the stall. Foil is fastest but softens bark; butcher paper is the standard compromise; no wrap costs time and buys crust.

Foil (Texas crutch)~12 h 15 m~14 h 15 m
No wrap~14 h 25 m~16 h 25 m

Cooking a flat instead of a whole packer? A trimmed flat is thinner and finishes faster — figure about 12 h 5 m at 275°F in paper.

275°F: hot and fast

275°F is the hot-and-fast school — the temperature many Texas joints quietly run because time is money. At 0.9 hours per pound, a 16 lb packer finishes in about 13 h 25 m wrapped in paper. That turns brisket from an overnight commitment into a same-day cook — for a 5 PM dinner you light the smoker at 1:30 AM.

The trade is attention. Everything moves faster at 275°F, including the window between perfect and overdone, so probe earlier than you think you need to and trust feel over the clock. Wrapping is close to mandatory here — the bark sets fast, and paper keeps the flat from drying while the point finishes.

A 16 lb packer is a big brisket. Thickness, not weight, is what really sets cook time, and big packers are thick — hold the estimate loosely, expect the stall to drag, and lean on the built-in hold if it finishes early.

How many people does a 16 lb brisket feed?

Trimming and a long cook take roughly half the raw weight, so a 16 lb packer yields about 8 lbs of sliced brisket. Plated at half a pound per adult, that is 16 people; chopped into sandwiches at a third of a pound, closer to 24 servings. Feeding a crowd near 15?

Quick answers

How long does a 16 lb brisket take at 275°F?

About 13 h 25 m wrapped in butcher paper, or 14 h 25 m unwrapped — plan 15 h 25 m total with a 2-hour rest. The honest range is 13 h 45 m to 17 h, because thickness matters more than weight and no two briskets cook alike.

When should I start a 16 lb brisket at 275°F for dinner at 5 PM?

Put it on at 1:30 AM. That includes the cook plus a 2-hour rest, and the start time is rounded down to the quarter hour — starting early is free, because a wrapped brisket holds for hours.

How many people will a 16 lb brisket feed?

A 16 lb raw packer yields roughly 8 lbs of sliced brisket after trimming and cooking — about 16 adults as a plated main at half a pound each, or around 24 sandwiches at a third of a pound each.
