What Is Corned Beef?

Corned beef is a type of salt-cured beef. The meat, typically a brisket, sits in a salty brine for at least a week. You can corn beef at home, but many home cooks prefer to buy an already cured beef to cook. The corned beef is cooked long and slow—and the result is a tender piece of meat.

The salt brine can be flavored with different spices. These might include a mix of coriander seeds, mustard seeds, black peppercorns, cinnamon sticks, bay leaves, and cloves.

Tips for Making the Best Slow-Cooker Corned Beef and Cabbage

  • Corned beef and cabbage will take about five hours to cook on the high setting, and 10 hours on the low setting.
  • We use Savoy cabbage because we like the way it looks—and tastes. Feel free to use regular green cabbage if you prefer.
  • When cutting the cabbage, be sure to leave the root end in so the wedges stay intact. This makes a much better presentation.
  • Add the cabbage wedges after the root vegetables toward the end of cooking since they take less time to soften than carrots, onions, and celery. This ensures the cabbage is still green and appetizing, but is also tender when the meal is ready to serve. Allow about 45 mins for the cabbage if cooking the corned beef on high, and about 1 1/2 hours if cooking on low.

The Right Way to Slice Corned Beef

Let the corned beef rest for 10 minutes once it is finished cooking. This allows time for the meat juices to redistribute. If you slice corned beef immediately, the juices will seep out and the meat will seem dry.

  1. Place the corned beef fat-side down on a chopping board. Use a sharp carving knife to remove any excess fat, if desired.
  2. Slice the corned beef against the grain.

Ingredients

  • 2 celery stalks, cut into 3-inch pieces

  • 3 carrots, cut into 3-inch pieces

  • 1 small yellow onion, cut into 1-inch wedges (root end left intact)

  • ½ pound small potatoes, halved if large

  • 6 sprigs thyme

  • 1 corned beef brisket (about 3 pounds), plus pickling spice packet or 1 tablespoon pickling spice

  • ½ head Savoy cabbage, cut into 1 ½-inch wedges

  • Grainy mustard, for serving

How to Store Corned Beef

Once cooked and cooled completely, corned beef can be refrigerated for three to four days—or frozen for two to three months. If you have uncooked corned beef, store it in the pouch with the pickling spices as you bought it and in the refrigerator for five to seven days.

Frequently Asked Questions

  • Do you need to rinse corned beef before cooking?

    Yes, corned beef should be rinsed because it is cured in a salt brine; there is probably excess salt on the meat. The uncooked corned beef should be rinsed under cool running water before it is cooked.

  • Is corned beef and cabbage a traditional Irish food?

    No, beef was relatively rare and pricey in Ireland, and corned beef and cabbage was not a well-known dish. Bacon and cabbage or a stew with lamb were more common foods. Corned beef became popular with Irish settlers in the United States, where beef was much more affordable.

  • Can you boil or bake corned beef and cabbage?

    Yes, corned beef can be boiled or baked in the oven. The most common preparation is boiling, whether on the stovetop or in a slow cooker or Instant Pot.
