How to Make Slow Cooker Corned Beef

Step 1: Prep the Slow Cooker

Place onion, carrot, celery, bay leaves, and cloves into the bottom of your slow cooker. Pour in the apple juice and 1 cup water.

Place the corned beef brisket on top of the vegetables.

Step 2: Cook Low and Slow

Cover and cook on LOW for 8 hours, turning the brisket halfway through if possible.

The meat should be fork-tender and easy to slice.


How to Make the Warm Mustard Cabbage

Step 3: Prep the Cabbage

Place thinly sliced cabbage into a large heatproof bowl.

Step 4: Make the Dressing

In a small saucepan over medium heat, combine:

  • Red onion
  • Caraway seeds
  • Olive oil
  • Several grinds of black pepper

Bring to a gentle simmer and cook for 12–15 minutes until the onion softens.

Remove from heat and stir in the whole-grain mustard (don’t worry if it looks slightly lumpy). Pour immediately over the cabbage and toss with tongs until slightly wilted and glossy.

Season with salt, extra pepper, and stir in the sherry vinegar. Add red bell pepper and parsley. Toss again and adjust seasoning.


Step 5: Slice and Serve

Transfer the brisket to a cutting board and rest for 5–10 minutes.

Discard most of the braising liquid, reserving about ½ cup.

Slice the brisket against the grain, arrange on a platter, and drizzle with the reserved braising liquid.

Serve with the warm mustard cabbage spooned over or alongside.


Serving Suggestions

This dish pairs beautifully with:

  • Steamed red potatoes
  • Irish soda bread
  • Roasted carrots
  • Dijon mustard on the side

Storage Tips

  • Store leftovers in an airtight container up to 4 days in the refrigerator.
  • Corned beef freezes well for up to 2 months.
  • Reheat gently with a splash of broth to keep it moist.

Tips for Perfect Corned Beef

  • Always slice against the grain for maximum tenderness.
  • Low and slow cooking is key.
  • Don’t skip resting the meat before slicing.
  • Adding apple juice balances the saltiness beautifully.

Frequently Asked Questions

Can I cook this on HIGH?

Yes, but texture is best on LOW for 8 hours. If needed, cook on HIGH for 4–5 hours.

Can I add potatoes to the slow cooker?

Absolutely. Add halved red potatoes during the last 3 hours of cooking.

What if I don’t have sherry vinegar?

Apple cider vinegar works as a substitute.
