16 lb Brisket at 250°F

Wrapped in butcher paper, a 16 lb whole packer at 250°F runs about 17 h 5 m of cook time — plan 19 h 5 m door to table with a 2-hour rest. For dinner at 5 PM, put it on at 9:45 PM the day before. 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.

Wrapped or naked at 250°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)~15 h 40 m~17 h 40 m

Cooking a flat instead of a whole packer? A trimmed flat is thinner and finishes faster — figure about 15 h 25 m at 250°F in paper.

250°F: the workhorse

250°F is what most working pitmasters actually run, and the math shows why: at 1.15 hours per pound, a 16 lb packer takes about 17 h 5 m in butcher paper — hours faster than the same brisket at 225°F, with no real trade in tenderness. The fire is hot enough to power through the stall's worst stretch but not so hot that the flat dries out while the point catches up.

For a 16 lb brisket this is the flexible middle: start it late the night before and you are resting comfortably before a 5 PM dinner, with the hold absorbing any surprise.

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 250°F?

About 17 h 5 m wrapped in butcher paper, or 18 h 25 m unwrapped — plan 19 h 5 m total with a 2-hour rest. The honest range is 17 h 5 m to 21 h 10 m, because thickness matters more than weight and no two briskets cook alike.

When should I start a 16 lb brisket at 250°F for dinner at 5 PM?

Put it on at 9:45 PM the day before. 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.
