How to Cook Brisket Low and Slow

Low and slow brisket means cooking at 225-250°F for 12-16 hours until the internal temperature reaches 203°F. The key is patience, consistent temperature, and letting the meat rest properly. You'll know it's done when a probe slides through like butter.

Ingredients

Step by step

  1. Trim the brisket. Leave about ¼ inch of fat on the fat cap. Trim any hard fat and silver skin from the lean side. The fat will render down and keep the meat moist.
  2. Season generously. Coat all sides with your rub at least 2 hours before cooking, or overnight. Salt, black pepper, and garlic powder work perfectly. Press it into the meat so it sticks.
  3. Set up your smoker or oven. Heat to 225°F. If using a smoker, add wood chunks (oak or hickory work well). For oven cooking, use a heavy roasting pan with a wire rack.
  4. Place brisket fat-side up. The fat will baste the meat as it renders. Insert a probe thermometer into the thickest part of the flat, avoiding fat pockets.
  5. Cook until it hits the stall. This happens around 150-160°F internal temperature, usually 6-8 hours in. The temperature will plateau for hours. This is normal.
  6. Wrap or push through. Either wrap in butcher paper or foil to speed cooking, or leave unwrapped for better bark. Wrapped brisket finishes 2-3 hours faster.
  7. Cook to 203°F internal temperature. This takes 12-16 hours total. Test doneness by sliding a probe or toothpick through the meat - it should feel like warm butter.
  8. Rest for at least 1 hour. Wrap in towels and place in a cooler, or leave in a 170°F oven. The meat needs time to reabsorb its juices.
  9. Slice against the grain. Find the direction of the muscle fibers and cut perpendicular to them. Slice the flat thin, the point thicker.

Questions

How much brisket should I buy per person?
Plan for about ½ pound of raw brisket per person. A whole packer brisket usually weighs 12-16 pounds and feeds 20-25 people.
Can I cook brisket faster at higher temperatures?
You can cook at 275-300°F to cut time, but you won't get the same tender texture. Low and slow breaks down the tough connective tissue properly.
What if my brisket is tough?
Either it didn't cook long enough or you sliced with the grain instead of against it. Tough brisket can be chopped and mixed with sauce for sandwiches.
Should I flip the brisket while cooking?
No need to flip. Fat-side up lets the rendering fat baste the meat naturally. Some pitmasters prefer fat-side down to protect from direct heat.
