What Is Corned Beef and Cabbage?
Corned beef and cabbage is a traditional Irish-American dish often served on St. Patrick’s Day. The “corned” in corned beef refers to the large grains of salt historically used to cure the beef. The brisket is simmered until tender and typically served with cabbage, carrots, and potatoes.
History of Corned Beef and Cabbage:
Corned beef and cabbage was made popular in America as a meal to celebrate St. Patrick’s Day. Poor Irish immigrants in America made corned beef from beef brisket as it was the cheapest cut of meat. It was paired with cabbage since that was cheap too. It’s amazing that the tradition of eating corned beef and cabbage for St. Patrick’s Day has stuck for all of these years! If you’re in Ireland, you’re more likely to eat roasted lamb or savory fish, beef or shepherd’s pies on St. Patrick’s Day. Beef or lamb stew and colcannon are popular in Ireland too. The Irish don’t drink green beer, but they do enjoy plenty of Guinness.

Ingredients Needed:
- Corned beef brisket : The star of the dish; comes with a pickling spice packet.
- Pickling spice: Adds classic flavor (peppercorns, mustard seed, bay leaf, etc.)
- Carrots, celery, onion, potatoes: Hearty vegetables that cook alongside the beef
- Fresh thyme: Subtle herbal flavor
- Cabbage: Added at the end so it stays tender
- Grainy mustard: Perfect tangy finishing touch

How to Make Slow Cooker Corned Beef and Cabbage
- Add carrots, celery, onion, potatoes, and thyme to a 5 to 6 quart slow cooker.
- Place the corned beef fat-side up on top of the vegetables. Sprinkle with pickling spice.
- Pour in water—enough to almost cover the meat.
- Cover and cook on HIGH for about 4 hours + 15 minutes (until tender).
- Arrange cabbage over the corned beef, cover, and cook another 45 minutes on HIGH.
- Slice corned beef thinly against the grain.
- Drizzle with cooking liquid and serve with grainy mustard.
Alternate Method: Cook in the slow cooker for 8 hours + 30 minutes on LOW, then add cabbage and cook 1 hour + 30 minutes more on LOW.

Recipe Tips:
- Always slice corned beef against the grain for maximum tenderness.
- Don’t skip the resting time—let the meat sit for 5 to 10 minutes before slicing.
- Add cabbage later to avoid overcooking.
- Save leftover corned beef for sandwiches the next day. Or better yet, use this recipe for ham and cheese sliders, and substitute corned beef for the ham!

Though this recipe is a complete meal, you can serve it with a pint of Irish stout, Irish Soda Bread to soak up the juices, and mustard or horseradish sauce to go with the corned beef.
