FAQ
Can I make this in just a slow cooker?
Yes, brown the brisket first then transfer to slow cooker with liquids. Cook the cabbage separately on the stovetop since it needs higher heat to caramelize properly.
How do I know when the brisket is done?
The meat should be fork-tender and easily pull apart. If still tough after the recommended time, continue cooking in 30-minute intervals until tender.
Can I freeze the leftovers?
Yes, the brisket freezes well for up to 3 months. Freeze cabbage separately as it may become mushy. Thaw overnight before reheating gently.
