Prepare tender, flavorful corned beef and cabbage using your slow cooker. This hands-off recipe yields a perfect meal for any occasion, especially St. Patrick’s Day.

Ingredients

Scale
  • 1 (3 to 4 pound) corned beef brisket, with spice packet
  • 1 cup beef broth
  • 1 tablespoon brown sugar
  • 1 teaspoon whole black peppercorns
  • 1 teaspoon mustard seeds
  • 1 large onion, quartered
  • 4 medium carrots, peeled and cut into 2-inch pieces
  • 1 pound small red potatoes, halved
  • 1 medium head green cabbage, cut into 6 wedges

Instructions

  1. Place the corned beef, fat side up, in the basin of your slow cooker.
  2. In a small bowl, mix the beef broth, brown sugar, and the contents of the spice packet (discarding any bay leaves if present). Pour this liquid over the brisket. Sprinkle the peppercorns and mustard seeds around the meat.
  3. Arrange the onion, carrots, and potatoes around the sides of the brisket.
  4. Cover the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours. The internal temperature should reach 195 to 200 degrees Fahrenheit for tenderness.
  5. About 1 hour before the cooking time is complete, nestle the cabbage wedges on top of the meat and vegetables. Cover and continue cooking until the cabbage is tender.
  6. Carefully remove the corned beef from the slow cooker and place it on a cutting board. Tent loosely with foil and let it rest for 15 minutes before slicing against the grain.
  7. To make a simple gravy, skim any excess fat from the liquid remaining in the slow cooker. You can thicken this liquid slightly with a cornstarch slurry if desired, or serve the juices as is over the meat and vegetables.

Notes

  • For lower sodium, rinse the corned beef under cold water before placing it in the slow cooker. You can also reduce the amount of seasoning packet used.
  • If you prefer shredded corned beef slow cooker style, shred the meat after resting using two forks instead of slicing it.
  • To achieve perfectly cooked corned beef, rely on the long, slow cooking time rather than rushing the process on high heat.
