How Long To Smoke Beef Brisket? | Backyard Timing Guide

Beef brisket usually reaches tender in 8–16 hours at 225–250°F, depending on size, trimming, wrapping, and when the stall breaks.

Nothing tests patience like a full packer on the smoker. Time swings by hours from pit to pit, and that’s normal. The timeline below gives you dependable ranges and a plan you can follow without babysitting every minute.

Smoking Time For Beef Brisket By Size And Temp

Cook time hinges on weight, pit temperature, fat left on the flat, and whether you wrap. Use the ranges below as planning windows; tenderness decides the finish.

Cut & WeightPit TempEstimated Time To Tender*
Flat, 4–6 lb225°F6–9 hr
Flat, 4–6 lb250°F5–7 hr
Packer, 10–12 lb225°F12–16 hr
Packer, 10–12 lb250°F10–14 hr
Packer, 13–16 lb225°F14–20 hr
Packer, 13–16 lb250°F12–18 hr
Point, 5–8 lb250°F6–10 hr

*Ranges assume typical trimming, a stall near 150–170°F internal, and a wrap at the stall or later. Unwrapped cooks lean to the longer end.

Choose The Cut And Trim With Intention

A full packer (flat + point) gives the most forgiveness. Thicker points keep moisture while the flat carries pretty slices. Flats alone cook faster but dry out if trimmed hard. Leave a modest fat cap—about 1/4 inch—so the surface stays protected during the stall. Square off thin corners on a flat; thin lips finish early and can go crumbly before the middle turns soft.

Set The Pit Temperature And Manage Smoke

Stick with 225–250°F for steady rendering and clean bark. At 275°F you’ll shave time, but watch the flat edge and bark color. Thin blue smoke beats white billows every time; heavy white plumes push bitter flavors and slow drying of the bark. Let the fire run clean before meat goes on.

Track Internal Temperature And The Stall

Brisket climbs briskly to the mid-150s, then stalls near 150–170°F as surface moisture cools the meat through evaporation. The stall can sit for 1–3 hours. When it drags, wrap or ride it out. A tight wrap shortens cook time and softens bark a bit; no wrap keeps a stronger crust and adds time.

Wrap Or Ride It Out

Butcher paper wrap: breathes a little, keeps bark from going soggy, trims 45–90 minutes from a long cook.

Foil wrap: traps steam, speeds past the stall, and gives a softer bark. Handy for a late start or wind that keeps knocking down pit heat.

No wrap: best bark, longest timeline. Plan the high end of the range or bump the pit to 260–270°F once bark looks set.

Know When Brisket Is Ready

Ignore a single magic number. Tender brisket feels like warm butter when you slide a probe into the flat and the point. That often lands near 198–205°F internal, but tenderness wins over digits.

Food safety has its own line: whole beef roasts are safe at 145°F with a short rest, per the Safe Minimum Internal Temperature Chart. Pitmasters cook brisket past that point for texture, not safety. If you want a deeper dive on “low and slow” science for big cuts, Texas A&M’s Cooking And Smoking Barbecue page explains why 200–250°F pits suit briskets and butts.

Planning The Day: A Reliable Timeline

Work backward from when you want slices on the table. Add buffer for the stall and the rest. Here’s a pattern that lowers stress:

  • Night before: Trim, salt or rub, fridge overnight.
  • Early morning: Fire up the pit; let smoke run clean.
  • Meat on: Aim for 225–250°F steady.
  • Stall window: Expect it around 3–5 hours in.
  • Wrap (optional): Once bark sets and color looks deep.
  • Tender check: Start probing near 195°F internal.
  • Rest: At least 1–2 hours; longer rests are gold.

Time Plans For Common Setups

Use these plans as build-outs you can copy. The rest holds the schedule together even if the stall runs long.

ScenarioGame PlanTime Budget
12 lb Packer, 225°F, Paper WrapOn at 6 a.m.; stall 11 a.m.–1 p.m.; wrap at bark set; probe tender mid-afternoon; rest in a cooler.Cook 12–15 hr; rest 1–3 hr
14 lb Packer, 250°F, No WrapOn at midnight; hold pit steady; once bark is set, ride it; if timing slips, bump to 265°F late.Cook 12–18 hr; rest 2–4 hr
Flat, 5 lb, 250°F, Foil WrapOn at 8 a.m.; wrap at deep color; pull when probes glide; slice thicker to protect moisture.Cook 5–7 hr; rest 1–2 hr
Point Burnt Ends, 6 lb, 250°FSeparate after the stall; cube, sauce lightly, back on for caramelizing.Cook 6–9 hr; finish 45–90 min
Windy Day, Kettle SmokerUse a windbreak; run 250°F; consider paper wrap to speed past the stall.Cook +1–2 hr vs calm

Why Time Swings Happen

Stall Length

Evaporation is the governor. Higher humidity, a wet rub, or a foil wrap shortens the flat’s “sweat” period. A dry, breezy day stretches it.

Trim And Thickness

Fat left on the flat slows heat flow but shields meat. Thin flats finish sooner yet carry less margin for error.

Wood Choice

Oak or hickory give steady heat. Mesquite runs hot and can spike temps. Fruit woods burn cooler; plan a small bump in fuel.

Pit Type

Offset pits breathe well but lose heat when you open the lid. Pellet grills hold temp tightly but push lighter smoke. Ceramics retain heat, so lid checks cost less time.

How To Read Bark And Color

Set the wrap point by sight and touch. The surface should feel set—rub no longer smears on a gentle rub with a finger. Color lands deep mahogany, not black ash. If the bark looks pale past 160°F internal, leave it unwrapped a bit longer or keep spritzes light so the surface can dry and set.

Probing For Tender Without Tearing The Flat

Use a thin probe and test in three spots: thick flat center, flat near the point, and the point. Slide in with the grain to avoid leaving stripes on slices. If one zone still grabs, give it 15–20 minutes and test again. When all zones glide, you’re there.

Resting, Holding, And Slicing

Resting turns a decent cook into a keeper. Vent steam for 5 minutes to stop carryover, then wrap and hold warm. A dry cooler with towels will keep a packer in the 145–170°F pocket for hours. Holding blends juices back into the meat and evens texture end-to-end.

Slice the flat across the grain in pencil-thick slices. When you reach the point, rotate the slab 90 degrees and keep slicing across the new grain. Keep the knife long and sharp; sawing roughs up bark and squeezes juice onto the board.

Sample Day Plan: Dinner At 7 P.m.

This plan covers a 12–14 lb packer on a steady 250°F pit with a paper wrap.

  • 6:00 a.m. — Pit on, smoke runs clean.
  • 6:30 a.m. — Brisket on, point toward the firebox.
  • 11:30 a.m. — Internal near 160°F; bark looks set; wrap in paper.
  • 2:30–4:30 p.m. — Probe start at 195°F; pull when slides like butter.
  • 4:45 p.m. — Vent steam 5 minutes; rewrap; into a warmed cooler.
  • 7:00 p.m. — Slice and serve.

Troubleshooting Slow Or Fast Cooks

Cook Is Lagging

  • Bark is already set: bump pit to 265–275°F until internal climbs again.
  • Bark still soft: hold temp, wait for color to deepen, then wrap.
  • Fuel issue: clean ash from vents; add a split; keep light blue smoke.

Cook Is Racing

  • Lower pit to 225°F to protect the flat edge.
  • Switch to paper to slow steaming while guarding moisture.
  • Extend the rest to smooth texture if pull time lands early.

Seasoning And Spritz: Do They Change Time?

Salt early for even seasoning; coarse pepper sticks better after a light oil rub. A spritz cools the surface and can add minutes, so use it to manage bark color, not as a timer.

Weight-Based Planning Rule Of Thumb

At 225°F, plan around 1–1.5 hours per pound for a packer. At 250°F, plan 45–60 minutes per pound. Wrap trims the long end; no wrap leans long. These are planning numbers, not finish lines; probe feel ends the cook.

Safety, Storage, And Reheat

For safety, whole beef roasts are safe to eat once they hit 145°F and rest briefly, per the Safe Minimum Internal Temperature Chart. Slice leftovers within two hours, chill in shallow pans, and reheat to steaming hot. If you hold a cooked brisket for service, keep it above 140°F. Those steps keep food tasty and safe for guests.

Quick Reference: When To Act

  • Color looks right, rub set: wrap or ride unwrapped for a firmer crust.
  • Stall passes 2 hours: choose paper or foil to push through.
  • Probe meets light resistance near 200°F: check other zones; pull when all glide.
  • Flat edge looks dry: wrap and add a small beef tallow smear over that edge only.
  • Guests running late: hold wrapped in a warm cooler; the rest makes slices better, not worse.

Final Notes On Flavor And Feel

Time targets help, but your senses close the deal. Watch the bark, feel the probe, and give the meat a proper rest. Hit those marks and the clock takes care of itself.
