Before you start

Before beginning, ensure your workspace is clean and have your slow cooker ready. Verify that the brisket is fully thawed if frozen, as cooking from frozen can lead to uneven results and safety issues.

Trim any excessively thick fat caps from the brisket, as this helps the sauce adhere better to the meat rather than sitting on top of a layer of rendered fat. Have your barbecue sauce measured and ready to pour, and ensure you have a sharp carving knife for slicing the meat once it has finished cooking.

  • 4 lb beef brisket, trimmed
  • 2 cups barbecue sauce
  • fresh parsley, for serving

Instructions

Setting up the slow cooker

  1. Prepare the brisket
    Place the beef brisket into the slow cooker bowl. Pour the barbecue sauce evenly over the top of the meat, ensuring it is well-coated on all sides to allow the flavors to penetrate the thick cut during the long cooking process.
    Look for The brisket should be completely covered by the sauce.
    Tip Trim excess fat from the brisket before placing it in the slow cooker to ensure the final sauce is not too greasy.

At the end of this phase, the brisket should be neatly placed in the slow cooker with the barbecue sauce covering it completely. The kitchen should smell faintly of the sauce spices, and the brisket should be positioned to lie flat to ensure even heat distribution. Check that the slow cooker is plugged in and the settings are correctly adjusted to the low heat function.

The long, slow simmer

  1. Slow cook the beef
    Cover the slow cooker with the lid and set it to cook on low for 8 hours. Allow the meat to simmer in the sauce until it becomes extremely tender and easily pulls apart with a fork, reaching an internal temperature of at least 145°F (63°C). Once cooked, let the meat rest at least 3 minutes before slicing.
    Look for The meat is done when it is fork-tender and pulls away easily.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Avoid lifting the lid during the cooking process to maintain a consistent temperature and moisture level.

During the cooking phase, the slow cooker will emit a savory, rich aroma as the barbecue sauce deepens in flavor and the beef begins to tenderize. The liquid should be bubbling very gently, and the meat should look slightly darker as it absorbs the sauce. Ensure the lid remains tightly sealed throughout the entire duration to maintain the necessary humidity for a tender result.

Resting and final serving

  1. Rest and serve
    Remove the brisket from the slow cooker using metal tongs and place it on a clean cutting board. Let the meat rest for at least 15 minutes to allow the juices to redistribute. Slice the meat against the grain, garnish with fresh parsley, and serve with extra sauce.
    Look for The meat should be firm enough to slice but still very tender.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Slicing against the grain ensures each bite of brisket is as tender as possible.

Once the brisket is removed, it should look glistening and dark with a generous coating of sauce. The meat should be firm enough to hold its shape when sliced but should yield instantly under slight pressure.

After the required resting period, the slices should be moist and tender, with the garnish of fresh parsley providing a bright contrast to the deep, rich colors of the barbecue sauce.

Common mistakes

Avoid the temptation to check on the brisket too frequently, as opening the slow cooker lid releases heat and steam, which significantly increases the cooking time.

Another common mistake is slicing the meat while it is still piping hot and has not had time to rest; failing to rest the meat will cause the juices to run out, resulting in a drier final product. Finally, ensure the meat is not placed on a surface that has been contaminated by raw juices.

How to tell it’s done

The brisket is perfectly cooked when it is fork-tender. Use a meat thermometer to ensure the center of the roast has reached an internal temperature of at least 145°F (63°C).

Once this temperature is achieved, the meat will be safe to eat and should have a texture that allows it to be cut easily with just a fork. Remember to let the meat rest for at least 15 minutes after cooking to ensure the juices are retained.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
