Corned Beef Crock Pot Recipe (Slow Cooker Corned Beef and Cabbage)

This corned beef crock pot recipe is the easiest way to make tender corned beef and cabbage: rinse a corned beef brisket, set it on onions in your slow cooker with the spice packet, broth and a little brown sugar, and cook it 8 to 10 hours on LOW. Add potatoes and carrots at the start and the cabbage for the last 1½ to 2 hours, so everything finishes together and nothing turns to mush.

The short answer to how long to cook corned beef in a crock pot: 8 to 10 hours on LOW or 5 to 6 hours on HIGH for a 3 to 4 pound brisket, until a fork slides in easily. Below you’ll find the best cut to buy, the step-by-step method, a timing chart by weight, how to slice it, a glaze option, what to do with leftovers and an FAQ.

Why You’ll Love Corned Beef in a Crock Pot

• Hands-off. About 20 minutes of prep, then the slow cooker does the work.
• Very tender. Long, gentle heat breaks down the tough brisket into soft, sliceable meat.
• A full dinner in one pot. Meat, potatoes, carrots and cabbage all cook together.
• Not too salty. Rinsing the brisket and using low-sodium broth keeps the salt in check.
• Great leftovers. Reuben sandwiches and corned beef hash are the best part of the week.

What Is Corned Beef?

Corned beef is beef brisket that has been cured in a salty brine with spices like peppercorns, mustard seed, coriander and bay. The word “corned” comes from the large grains, or “corns,” of salt once used to cure it. The cure gives the meat its pink color and its salty, spiced flavor. It’s sold raw in a sealed bag with brine and usually a small spice packet.

Corned beef and cabbage is a St. Patrick’s Day classic in the United States, but it’s a cozy, budget-friendly dinner any time of year.

Flat Cut vs Point Cut

For a slow cooker, either works. Flat cut slices more neatly; point cut stays juicier. A brisket shrinks by about a third as it cooks, so plan on ½ pound of raw corned beef per person.

Ingredients

• Corned beef brisket: 3 to 4 pounds, with its spice packet.
• Onion: 1 large, cut into thick slices.
• Garlic: 4 cloves, smashed.
• Liquid: 2 cups low-sodium beef broth plus 1 cup water, or swap 1 cup of the liquid for a dark beer like stout.
• Brown sugar: 2 tablespoons, to balance the salt.
• Bay leaves: 2.
• Baby potatoes: 1½ pounds, halved if large.
• Carrots: 1 pound, cut into 2-inch pieces.
• Green cabbage: 1 small head, cut into 8 wedges through the core.
• Butter and parsley for serving, plus grainy mustard on the side.

No spice packet? Mix 1 tablespoon pickling spice, or 1 teaspoon each of whole black peppercorns, mustard seeds and coriander seeds, plus ½ teaspoon allspice berries and a pinch of red pepper flakes.

How to Make Corned Beef in a Crock Pot, Step by Step

1. Rinse. Take the brisket out of the package, rinse it under cold water to remove the surface brine and pat it dry.
2. Layer the vegetables. Put the onion slices and garlic in the bottom of a 6-quart slow cooker. Add the potatoes and carrots around the edges.
3. Add the beef. Lay the brisket on the onions, fat side up. Sprinkle the spice packet over the top.
4. Add the liquid. Stir the brown sugar into the broth and water and pour it around the meat. Add the bay leaves. The liquid should come about halfway up the brisket.
5. Slow cook. Cover and cook 8 to 10 hours on LOW or 5 to 6 hours on HIGH.
6. Add the cabbage. For the last 1½ to 2 hours on LOW (or last 1 hour on HIGH), tuck the cabbage wedges around the beef. Cover again quickly.
7. Check for doneness. A fork should slide into the thickest part with little resistance.
8. Rest and slice. Move the beef to a board and rest it 10 minutes. Slice it thinly against the grain.
9. Serve. Plate the beef with the vegetables, add a pat of butter and parsley to the cabbage and potatoes, and spoon a little of the cooking liquid over the meat.

How Long to Cook Corned Beef in a Crock Pot

Cooking corned beef in a crock pot is all about time, not temperature. Here are the times that work for most slow cooker corned beef.

Times depend on the size and thickness of the brisket and your slow cooker, so start checking at the low end.

LOW gives the most tender result. Cooking on HIGH works but can leave the meat a little firmer. Don’t lift the lid more than you need to; each peek adds 15 to 20 minutes.

When Is Slow Cooker Corned Beef Done?

The USDA safe minimum for whole cuts of beef, including brisket, is 145°F with a 3-minute rest, according to the FoodSafety.gov safe minimum internal temperatures chart. But corned beef is a tough cut, so it needs to go much higher, to about 190 to 205°F, before the connective tissue melts and it becomes tender. Use the fork test: if it goes in easily and the meat starts to pull apart, it’s ready.

Cured corned beef often stays pink inside even when fully cooked. That color comes from the curing salts, not from undercooking.

Crock Pot Corned Beef and Cabbage: Getting the Vegetables Right

If your slow cooker is full, cook the cabbage separately: simmer the wedges in a pot with 2 cups of the crock pot liquid for 12 to 15 minutes, or roast them at 425°F for 20 to 25 minutes with butter and pepper.

How to Slice Corned Beef

1. Rest the meat 10 to 15 minutes so it firms up slightly and holds its juices.
2. Look for the lines of muscle fibers running across the top.
3. Turn the brisket so your knife cuts across those lines, not along them.
4. Slice about ¼ inch thick with a long, sharp knife.
5. For a point cut, the grain changes direction partway through. Cut the brisket in half where the grain shifts, then slice each half against its own grain.

Slicing with the grain leaves long, stringy fibers that are hard to chew, even when the meat is tender.

Optional: Brown Sugar Mustard Glaze

For a sweet, sticky crust, glaze the cooked corned beef under the broiler. Stir together ¼ cup brown sugar, 2 tablespoons Dijon or grainy mustard and 1 tablespoon of the cooking liquid. Set the cooked brisket on a foil-lined sheet pan, fat side up, brush on the glaze and broil 3 to 5 minutes until bubbly, watching closely so the sugar doesn’t burn. Rest 5 minutes and slice.

Crock Pot vs Instant Pot vs Oven vs Stovetop

Slow cooker corned beef is the most hands-off method, but here’s how the others compare if you’re short on time:

For a weekday, the crock pot wins: start it before work and dinner is ready when you get home. For more slow cooker beef ideas, try our shredded beef or crockpot beef stew.

Equipment You Need

• A 6-quart slow cooker. It fits a 3 to 4 pound brisket plus vegetables. A 4-quart works for a small brisket without the cabbage.
• A long, sharp slicing knife for thin, even slices.
• A large cutting board with a groove to catch the juices.
• Tongs and a slotted spoon for lifting out the meat and vegetables.
• An instant-read thermometer if you want to check the temperature.

Making Corned Beef in a Crock Pot for a Crowd

For a St. Patrick’s Day party or a big family dinner, plan on ½ pound of raw brisket per adult. Two 3-pound briskets fit side by side in a 7-quart or larger oval slow cooker; overlap them slightly if needed. Cook the potatoes, carrots and cabbage in a second slow cooker or a large pot on the stove using some of the cooking liquid, so the meat isn’t crowded. Slice the beef just before serving and keep it warm in a covered dish with a ladle of the hot liquid poured over.

Timing Plan for Dinner at 6 PM

1. 8:00 AM: rinse the beef, load the slow cooker and set it to LOW.
2. 4:00 PM: add the cabbage wedges and cover quickly.
3. 5:30 PM: check that the beef is fork-tender. Move it to a board to rest.
4. 5:45 PM: slice the meat; mix the horseradish sauce; warm the bread.
5. 6:00 PM: serve the corned beef and cabbage with butter, parsley and mustard.

Flavor Variations

• Beer-braised: replace 1 cup of the liquid with a stout or dark ale for a deeper, malty flavor.
• Apple cider: swap the water for apple cider and skip the brown sugar.
• Extra spice: add 1 teaspoon whole peppercorns, 4 whole cloves and a cinnamon stick.
• Honey mustard: stir 2 tablespoons honey and 1 tablespoon mustard into the liquid.
• Less salty: soak the brisket in cold water in the fridge for 1 to 2 hours before cooking, and use water instead of broth.

What to Serve With Corned Beef

• Sauces: grainy mustard, horseradish cream (sour cream plus prepared horseradish) or a creamy parsley sauce.
• Bread: Irish soda bread or rye bread with butter.
• Sides: buttery mashed potatoes instead of boiled ones, roasted root vegetables or a simple green salad.
• For another cabbage dinner, see our ground beef and cabbage recipes.

Leftover Slow Cooker Corned Beef Ideas

Is Corned Beef and Cabbage Healthy?

Corned beef and cabbage is a hearty meal with plenty of protein and vegetables. The cabbage, carrots and potatoes add fiber and vitamins. The main thing to watch is salt: corned beef is cured, so it’s very high in sodium. To keep it in check, rinse or soak the brisket, use water or low-sodium broth, don’t add extra salt to the pot, and fill half the plate with cabbage and carrots. Trimming the fat cap after cooking also cuts down on saturated fat.

If you make corned beef in a crock pot often, try a flat cut for leaner slices, and serve it with a big green salad on the side.

Storage, Freezing and Reheating

• Fridge: refrigerate within 2 hours of cooking. Store the sliced beef with a little cooking liquid in a sealed container for 3 to 4 days, the time for cooked meat leftovers in the FoodSafety.gov cold food storage chart.
• Freezer: freeze sliced corned beef in its liquid for 2 to 3 months. Cabbage and potatoes don’t freeze well; eat those within a few days.
• Reheat: warm slices in a covered skillet with a splash of the cooking liquid over medium-low heat, or in a covered dish at 300°F, until steaming hot (165°F).

Slow Cooker Food Safety

Always thaw a frozen corned beef in the fridge before it goes into the slow cooker, so it doesn’t sit too long at unsafe temperatures. Keep the lid on, and if the power goes out while you’re away, throw the food out even if it looks done. The USDA explains more in its slow cookers and food safety guide.

Troubleshooting

Corned Beef Crock Pot FAQ

Quick answers to the questions people ask most about this corned beef crock pot dinner.

Do you put corned beef in a crock pot fat side up or down?

Fat side up. As the fat melts, it bastes the meat. Trim off any thick fat after cooking.

Should the corned beef be covered with liquid?

About halfway up the meat is enough. The brisket and vegetables release more liquid as they cook.

Can you overcook slow cooker corned beef?

Yes. After 11 or 12 hours on LOW, it can fall apart and turn stringy. If that happens, shred it and use it for hash or sandwiches.

Do I need to rinse corned beef?

Rinsing removes some of the salty surface brine and is a good idea, especially if you use broth.

Is HIGH or LOW better?

LOW gives more tender meat. Use HIGH only when you’re short on time.

Can I cook frozen corned beef in a crock pot?

No. Thaw it in the fridge first, which takes 1 to 2 days for a 3 to 4 pound brisket.

Why is my cooked corned beef still pink?

The curing salts keep it pink. Check that it’s tender and above 145°F rather than judging by color.

What goes in a corned beef crock pot besides the meat?

Onion, garlic, the spice packet, broth or beer, a little brown sugar and bay leaves. Potatoes and carrots go in at the start; cabbage goes in near the end.

Can I make corned beef and cabbage without potatoes?

Yes. Leave them out and serve the slow cooker corned beef with mashed cauliflower, rye bread or roasted root vegetables instead.
