Make the most tender corned beef brisket using your slow cooker. This easy recipe includes a sweet and savory brown sugar mustard glaze for deep flavor, paired with classic cabbage and potatoes.

Ingredients

Scale
  • 1 (3 to 4 pound) corned beef brisket with spice packet
  • 1 cup beef broth
  • 1 large yellow onion, cut into wedges
  • 4 medium carrots, peeled and cut into 2-inch pieces
  • 1.5 pounds small red potatoes, halved
  • 1 head green cabbage, cut into 8 wedges
  • For the Glaze:
  • 1/2 cup packed brown sugar
  • 1/4 cup Dijon mustard
  • 2 tablespoons apple cider vinegar
  • 1 teaspoon dry mustard powder

Instructions

  1. Place the corned beef brisket, fat side up, in the basin of your slow cooker. Sprinkle the contents of the spice packet over the meat. Pour the beef broth around the meat.
  2. Arrange the onion wedges, carrots, and potatoes around the corned beef. Do not place vegetables on top of the meat.
  3. Cover the slow cooker and cook on LOW for 8 to 10 hours, or on HIGH for 4 to 5 hours, until the beef is fork-tender.
  4. About 30 minutes before the cooking time ends, prepare the glaze. In a small bowl, whisk together the brown sugar, Dijon mustard, apple cider vinegar, and dry mustard powder until smooth.
  5. Remove the cooked cabbage wedges from the slow cooker and set them aside on a serving platter. Remove the potatoes and carrots and place them around the cabbage.
  6. Place the corned beef on a large cutting board. Brush half of the brown sugar mustard glaze over the top of the brisket.
  7. Increase the slow cooker setting to HIGH (if using LOW) and add the cabbage wedges to the liquid in the slow cooker. Cook for 15 minutes to heat through.
  8. Slice the corned beef against the grain into half-inch thick pieces. Arrange the sliced corned beef on the platter with the vegetables.
  9. Brush the remaining glaze over the sliced corned beef. Serve immediately with the cooked vegetables and cooking liquid if desired.

Notes

  • For an even crispier crust, place the sliced corned beef on a baking sheet after glazing and broil for 2 to 3 minutes, watching closely to prevent burning.
  • Save your leftover corned beef for making classic Reuben sandwiches or corned beef hash the next day.
  • If you prefer a Guinness braised corned beef, substitute 1 cup of Guinness stout for the beef broth.
