Place brisket slices into the slow cooker, cover with sauce, and reheat for 45-75 minutes or until hot and bubbly. Serve warm. Place half of the chopped onions, 5 of the garlic cloves and the bay leaves in the bottom of the slow cooker. Rinse the brisket and pat dry. Sprinkle both sides of the meat lightly with black pepper and salt.
You definitely can overcook brisket in the slow cooker, so we highly recommend two tips to ensure your brisket is perfectly cooked: cook low and slow, and keep an eye on it. Make sure your slow cooker is set to low instead of high to avoid overcooking.
Beef brisket is covered in a blend of savory spices and liquid smoke, then smothered in your favorite barbecue sauce and slow cooked to perfection. The most delicious, tender brisket you'll ever try! Mix together all of the seasonings and rub over brisket.
There are even some chefs that insist a proper braised brisket is one made 24 hours ahead of time, then reheated in the oven an hour before it’s meant to be served. You can store it in the pot (once cooled) in your fridge. Or, remove the brisket and store it in a few inches of the braising liquid and use the remaining liquid to make your sauce.
