Make classic corned beef and cabbage easily in your slow cooker. This hands-off method results in tender beef and soft vegetables, perfect for a hearty, traditional dinner or St. Patrick’s Day.

Ingredients

Scale
  • 1 (3 to 4 pound) corned beef brisket with spice packet
  • 1 cup water or beef broth
  • 1 tablespoon brown sugar
  • 1 teaspoon mustard powder
  • 1 teaspoon black peppercorns
  • 1 teaspoon dried thyme
  • 1 large onion, quartered
  • 4 medium carrots, peeled and cut into 2-inch pieces
  • 2 pounds small red potatoes, halved
  • 1 medium head green cabbage, cut into 8 wedges
  • Optional: Prepared horseradish for serving

Instructions

  1. Place the corned beef brisket, fat side up, in the basin of your slow cooker.
  2. In a small bowl, mix the water or broth, spice packet contents, brown sugar, mustard powder, peppercorns, and thyme. Pour this mixture over the corned beef.
  3. Arrange the onion and carrots around the sides of the beef.
  4. Cover and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the beef is very tender.
  5. About 1 hour before the cooking time is complete, add the potatoes to the slow cooker, nestling them around the beef.
  6. Add the cabbage wedges on top of the other vegetables. Cover and continue cooking until the cabbage is tender, about 45 to 60 minutes.
  7. Remove the corned beef from the slow cooker and let it rest on a cutting board for 10 minutes before slicing against the grain.
  8. Arrange the sliced beef, cabbage, carrots, and potatoes on a platter. Spoon some of the cooking liquid over the meat and vegetables.
  9. Serve immediately with prepared horseradish, if desired.

Notes

  • For extra flavor, you can use beer instead of water or broth in the liquid mixture.
  • Save your leftover corned beef to make Reuben sandwiches or corned beef hash the next day.
  • If you prefer a stronger cabbage flavor, add the cabbage wedges during the last 2 hours of cooking on LOW.
