The recommended cooking time for corned beef in a slow cooker varies slightly depending on the recipe, but the general consensus is:
- Cook on low for about 7 to 9 hours or sometimes up to 10 hours, until the beef is tender and easy to pull apart.
- Alternatively, cook on high for about 4 to 4 ½ hours , though slow and low is preferred for tenderness.
If adding cabbage, it is typically added in the last 45 minutes to an hour to cook through without becoming mushy. Some recipes suggest adding vegetables like potatoes and carrots earlier in the cooking process. So in summary, the best practice is to cook corned beef on low for 7-9 hours or on high for about 4-4 ½ hours until tender.
