How Long to Smoke Brisket

A beef brisket smoked at a temperature between 225°F and 250°F (107°C to 121°C) will generally take about 1 to 1 1/2 hours per pound to cook. Based on this estimate, a common 12 pound packer brisket could require anywhere from 12 to 18 hours in the smoker. This range applies to both whole packer briskets and the smaller brisket flat.

This calculation is only a starting point. The exact time can vary, so it is better to cook to a target tenderness rather than watching the clock. Experienced pitmasters rely on the feel of the meat to know when it is ready. The final test of doneness is always how easily a thermometer probe glides into the thickest part of the meat.

Good to know

• Expect a stall where the temperature stops rising for hours
• Pitmasters judge brisket by tenderness rather than a set time

What changes the cooking time

The rule of 1 to 1 1/2 hours per pound is a helpful guide for planning, but several factors can make the actual cooking time shorter or longer. Understanding these variables will help you manage the cooking process.

• Meat characteristics: The thickness of the brisket is more important than its total weight. A thicker cut will take longer for heat to penetrate to the center. The amount and type of fat can also affect how it cooks.
• Smoker temperature: Maintaining a consistent temperature is critical. If your smoker runs hotter or cooler than the target range of 225 to 250°F, it will directly change the cooking duration. Fluctuations in temperature will also extend the time.
• The stall: It is normal for a brisket’s internal temperature to stop rising for several hours during the cook. This phase, known as the stall, happens as moisture evaporating from the surface cools the meat. This is a primary reason why brisket cooking times are so unpredictable.

How to tell when brisket is done

Since time is an unreliable measure, the best way to determine when brisket is finished is by testing for tenderness. A brisket is ready when a thermometer probe slides into the thickest part of the flat with very little resistance, similar to a probe entering soft butter.

While the United States Department of Agriculture (USDA) states that beef is safe to eat once it reaches an internal temperature of 145°F (63°C), brisket requires a much higher final temperature to become tender. The tough connective tissues in the cut do not break down and render until the meat is cooked well past this point. This is why tenderness, not a specific final temperature, is the preferred indicator of doneness.

The only way to accurately check for tenderness and monitor the internal temperature throughout the cook is with a reliable meat thermometer. It removes the guesswork from the process and is an essential tool for smoking brisket.

Tips for better results

Patience is key when smoking brisket. Rushing the process or pulling the meat too early can result in a tough texture. Always allow more time than you think you will need.

After the brisket is tender and removed from the smoker, it needs to rest. Wrap the brisket and let it rest for at least one hour. This resting period allows the muscle fibers to relax and reabsorb the juices that moved to the surface during cooking. Slicing into a brisket without a proper rest will cause the juices to run out, leaving the meat dry.

For food safety, the USDA sets minimum internal temperatures for various cooked foods. For example, all poultry must reach 165°F (74°C) and ground beef must reach 160°F (71°C). While brisket is cooked to a much higher temperature for quality, these official minimums are important for other types of cooking.
