Ingredients
- 3 to 3½-pound ready-to-cook corned beef, preferably flat-cut
- 1¼cups semi-dry white wine, such as Riesling
- 1pound red or Yukon gold potatoes, cut into 1- to 2-inch pieces
- 2 to 3large carrots (about ½ pound), peeled and cut into 1- to 2-inch pieces
- ½ small head green or savoy cabbage (about 1 pound), core left intact, cut into 4 wedges
- 3tablespoons Dijon mustard, plus more for serving
- 2tablespoons honey
- Flaky sea salt, if necessary
- Black pepper
Preparation
- Step 1
Remove the corned beef from its packaging in the sink and reserve the spice packet. Rinse the beef well under cold running water and pat it dry with paper towels. (If you don’t rinse off the brine, the meat will be too salty.) If there is a substantial fat cap on top of the beef, place the beef on a cutting board and trim most of it, if you’d like. (The fat will not completely render away during cooking.) Be sure to leave at least a thin layer of fat on top, about ⅛- to ¼-inch thick, to keep the meat moist.
- Step 2
Transfer the corned beef into a 6- to 8-quart slow cooker with the fat cap facing up. Add the wine and the spices from the packet. Cook on high for 4 hours.
- Step 3
Reduce the heat to low. Baste the beef with the cooking liquid. Drop the potatoes and carrots into the liquid surrounding the beef. Lay the cabbage wedges on top. Cook on low for 4 hours, or until the vegetables and beef are tender. (A paring knife should slip easily into the beef, though the meat shouldn’t be falling apart.)
- Step 4
Heat the broiler to high. Stir together the mustard and honey in a small bowl. Using tongs, remove the corned beef from the slow cooker and put it on a foil-lined sheet pan. Spread the honey-mustard all over the top and sides of the beef and place it under the broiler. Cook until the glaze bubbles and caramelizes in spots, about 3 minutes.
- Step 5
Let the corned beef rest for 5 to 10 minutes then slice it against the grain into ½-inch slabs. Place the beef slices on the serving platter alongside the vegetables and drizzle everything with a little bit of the cooking liquid. Taste the vegetables, and season them with flaky sea salt, if necessary. (The beef will not need to be seasoned with salt.) Season the beef and vegetables to taste with black pepper. Serve with Dijon mustard.

I have always used 2 whole cloves, 10 whole black peppercorns, 2 bay leaves, and 1/4 teaspoon mustard seeds. This was my part Irish mother’s recipe.
I would substitute the wine with Guinness Beer. I’ve braised my corn beef with it for years, adds amazing flavor. I also dislike boiled vegetables, so I roast a combination of carrots, Brussels sprouts and small red potatoes on a separate sheet pan in the oven.
What if there is no spice pack included? What spices should be used instead?
This turned out well. I added a smear of mustard and brown sugar to the top of the brisket. I ran out of room in the slow cooker, so I roasted my potatoes separately. Overall good flavor. Probably serves more than the four indicated in the recipe.
4 hours was too long to cook carrot and potatoes. They were very mushy. Next time, I will only cook them 60 minutes.
I made this two days ago and it was delicious, though for some reason, the wine flavor was stronger than I'd expected, especially in the meat. The potatoes, carrots, and cabbage were perfectly cooked and did NOT need any additional salt. I think if I make this again, I might reduce the amount of wine and substitute broth or even water.
