The typical cooking time for brisket in a slow cooker on low heat is generally around 7 to 10 hours. Some recipes recommend 7-8 hours on low for a 3-5 pound brisket, with the option to cook up to 9-10 hours if the meat is not yet tender. Cooking on high speed generally takes shorter, about 4-6 hours, but low and slow is preferred for tenderness. The brisket is done when it easily shreds with a fork or becomes tender to the touch. Here are various slow cooker brisket timing guidelines from different sources:
- 7-8 hours on low (3-5 lbs brisket) with possible extra 1-2 hours if not tender.
- 7-8 hours on low, or 4-6 hours on high, depends on size.
- 8-10 hours on low for about 3 lbs brisket, usually the full 10 hours needed.
- About 6 hours on high or 8 hours on low for a 4.5 lb brisket.
- 8 to 10 hours on low for 1.5 to 2 kg (3 to 4 lbs) brisket.
- 6 to 8 hours on low.
In summary, the standard recommended practice is cooking brisket in a slow cooker on low heat from about 7 to 10 hours, depending on the brisket size and desired tenderness, with some flexibility to extend cooking if needed to achieve fork-tender meat. This ensures the brisket becomes tender and flavorful without drying out, typical in slow cooker recipes.
