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.
