Quick answer
For a 4 PM Memorial Day serving of a 12 lb brisket at 225°F: light the smoker at 11 PM Sunday May 24, brisket on at midnight Monday. For hot-and-fast at 275°F: light at 4 AM Monday, brisket on at 5 AM. Always plan a 1-hour minimum rest in a dry cooler.
Start times by brisket size and method
- 10 lb brisket @ 225°F: Smoker lit 11 PM Sunday, on at 1 AM Monday (14 hours total)
- 12 lb brisket @ 225°F: Smoker lit 11 PM Sunday, on at midnight (16 hours total)
- 14 lb brisket @ 225°F: Smoker lit 9 PM Sunday, on at 10 PM (18 hours total)
- 12 lb brisket @ 275°F (hot & fast): Smoker lit 4 AM, on at 5 AM Monday (10 hours total)
Why these specific times
Brisket cook time is dominated by the stall — the 4–6 hour plateau around 165°F internal where moisture evaporation cools the meat as fast as your smoker heats it. The rule of thumb of 75 minutes per pound at 225°F bakes in the stall. Hot and fast (275°F) cuts cook time roughly in half by burning through the stall faster, but produces less smoke ring.

Brisket size adjustments
Use the calculator on each cooking page for your exact weight, or apply these rules:
- 10 lb brisket: Subtract 1.5 hours from the 12 lb plan. Light 11 PM Sunday, on at 1 AM Monday.
- 12 lb brisket: Use the plan above as-is.
- 14 lb brisket: Add 2.5 hours to the 12 lb plan. Light 9 PM Sunday, on at 10 PM.
- 16 lb brisket: Add 5 hours. Cook the day before and reheat — see below.
The "cook ahead and reheat" option
Many central Texas BBQ joints cook brisket the day before service and reheat — and it often tastes better than fresh because the rested meat reabsorbs juices. For Memorial Day, this means cooking Sunday and reheating Monday morning.
- Saturday or Sunday: Smoke brisket to 203°F internal. Rest 1 hour. Refrigerate whole and unsliced (do not slice ahead).
- Monday morning: Wrap brisket in foil with 1/4 cup of beef tallow or beef broth. Reheat at 250°F (oven or smoker) for 1.5 hours.
- Just before serving: Slice against the grain. Serve immediately.
Trade-off: less crisp bark. Pro: total flexibility on cook day, way less stress.
Common Memorial Day brisket mistakes
- Slicing ahead. Sliced brisket dries out in 15 minutes. Slice to order, not "for the buffet."
- No rest. Brisket pulled at 203°F and immediately sliced will lose all its juice. The 1-hour rest is non-negotiable.
- Trusting time over temperature. Two 12 lb briskets can finish 2 hours apart. Probe-tender (probe slides in like warm butter) is the only reliable doneness signal.
- Not buying enough. A 12 lb raw brisket yields about 6 lb cooked. For 12 guests at 1/2 lb each, you need 6 lb cooked — leaving zero leftovers. Buy 14 lb raw if leftovers matter.
