Brisket takes a bit of prepping before it can be smoked, regardless of the temperature you cook. And it’s important to keep these steps in mind, or you’ll ruin the recipe, even if you got the timing right.

Freeze before Trimming

Keep the brisket in the freezer for an hour or so, to solidify the fat and make it easier to trim. And begin with the fat-side up, trimming that to about a quarter of its total thickness. As you reduce the fat layer, locate the hard fat, which is firm and waxy, and cut it off too- it doesn’t render when cooked.

You’ll repeat the trimming process for the other side when you flip the brisket. Also, don’t forget to cut off the silver skin on its sides.


You can choose between a dry rub or a broth injection for smoked brisket at 225F. And either option will result in a tasty result, so it’s a matter of preference. The dry rub incorporates your favorite spice mixes which are sprinkled and patted onto the meat before smoking. The injection however is used in combo with a dry rub, and mostly features beef broth with any powdered dry rub. Sometimes, phosphates are added to the broth to keep the meat moist as it cooks. After the meat is seasoned, it may be cooked right away or rested in plastic for six to 12 hours under chilled conditions.

Insert Meat Thermometer

Once the brisket is fully rested in the fridge, take it out and stick a probe into it for the meat thermometer. This way, you can monitor the cooking temperature as it smokes. You’ll want the probe at the flat area, about one inch between where it meets the point, for the most accurate reading.

Prepping the Smoker

Ensure to prepare the smoker in a sheltered area, so the wind doesn’t disturb the temperature as it cooks. If not, the smoker will take much longer to cook the brisket. Once this is done, start the smoker as instructed in the manual and like a chafing pan or baking sheet with heavy-duty foil. This will sit under the rack where the brisket with lay and catch any dripping fat.

Brisket Cooking Time at 225,

You’ll want the smoker to preheat to 180F before adding the brisket, and at this temperature, the meat will cook for about eight to 12 hours. It’s why most BBQ enthusiasts start this at night, cooking from about 9 pm or so. By the end, the brisket should internally reach around 150F. So, when you note this temperature, increase the smoker temperature to 225F.

The Stall

You’ll notice that at the 150F to 160F internal temperature mark, the thermometer may seem stuck. This is normal, and the period is nicknamed the Brisket Stall. At this point, the natural moisture has risen to the surface, slightly cooling the meat as it evaporates. And the process occurs faster than the smoker can cook it, causing a flatline in the internal temperature until the moisture is exhausted.

The brisket may take a while to break from this period, so wait for it. Afterward, let it cook until the thermometer indicates 195F to 205F, at which the meat will easily give way to a probe or toothpick. If you’re using a spritz, do it frequently but quickly as it smokes, so you don’t lose cooking heat.

The brisket’s total time should be calculated at 1½ hour per pound, plus an extra one hour for rest. By this rate a 16-pound brisket will cook for 18 to 24 hours, depending on the speed of the smoker.

Rest and Slice

Once the meat is done, wrap it in butcher paper, and a towel, and keep it in a cooler to rest for one hour or more. This gives the juices a chance to redistribute along with the tissues. After the resting period,

  • Two tablespoons of garlic powder
  • Two tablespoons of ground black pepper
  • Two tablespoons of kosher salt
  • One tablespoon of paprika
  • One can of root beer


  1. Set the brisket in the freezer for one hour or more, after which it should be removed for trimming. Then, start the smoker at 180F, and as it heats, trim most of the fat cap leaving about a quarter of it. Ensure to cut off the hard fat, as it doesn’t render during cooking.
  2. Combine the dry spices in a bowl and sprinkle them over the brisket. Ensure to pat it down so it sticks and reaches the entire surface. Then, wrap it in plastic and rest in the fridge for six to 12 hours.
  3. Transfer the brisket to the smoker with the fat cap down, and stick the internal thermometer probe. Cover the lid and smoke the brisket for eight to 12 hours (preferably overnight), or until the internal temperature reaches 150F.
  4. Increase the smoker temperature to 225F, and as the meat cooks, spritz it every 45 minutes to one hour with root beer.
  5. Smoke the brisket at 225F until the internal temperature hits 195F to 203F and a sharp probe can slide into the meat without resistance.
  6. Transfer the brisket from the grill into two layers of butcher paper and wrap it. Then, wrap it again in a towel, and keep it in a cooler to rest for one to four hours.
  7. Slice the meat across the flat, and perpendicularly for the point.
