Cook on low for 6 hours.TIP - Allow the brisket to rest for about 10 minutes after removing the lid from the slow cooker. Then use two spatulas (or one really long one) to carefully lift the brisket to a cutting board. You should be able to slice the meat with a sharp knife.
Usually when you buy a cut of brisket from the meat shelf, it’s already been trimmed for you. You can purchase larger, untrimmed, pieces at the butcher counter.
If you would like to sear the meat first, you most definitely can. Simply sear in tablespoon of olive oil until all sides are browned.
