Ingredients
  

Main Ingredients

  • 1 3-4 lb. corned beef with spice packet, flat cut
  • 4 carrots cut into pieces
  • 8 small red potatoes halved or quartered depending on size
  • 1 onion peeled, cut into chunks
  • 4 cups beef broth
  • 1/2 head cabbage coarsely chopped

Instructions
 

Preparation and Cooking

  • Rinse the corned beef thoroughly under cold water.
  • Carefully place the rinsed corned beef brisket into the slow cooker.
  • Pour the beef broth over the brisket in the slow cooker.
  • Open the seasoning packet and sprinkle its contents evenly over the meat.
  • Cover and cook on low for 8 to 9 hours, or until the corned beef is tender.
  • About halfway through the cooking time (after 4-4.5 hours), add the carrots, potatoes, and onion to the slow cooker.
  • If adding cabbage, incorporate it during the last hour of cooking to ensure it's tender but not mushy.

Notes

For best results, slice the corned beef against the grain before serving. Adjust cooking time slightly based on your slow cooker and desired tenderness of the meat and vegetables.
