Slow-Cooker Corned Beef with Veggies and Horseradish Sauce is something that’s a once-a-year splurge for me, but I do make corned beef either in the crockpot or in the pressure cooker every St. Patrick’s Day. The last few years I’ve been cooking it for my slightly Irish father, who isn’t on a diet and would love to have corned beef any time of year.

If you live in the U. S. most packages of corned beef come with a spice packet included, but if you don’t have one of those packets, this recipe from Mark Bittman’s How to Cook Everything will tell you what spices to use. Corned beef is easy to cook, but be careful not to overcook the vegetables. This year I’m going to try serving the corned beef to dad with some Roasted Cabbage with Lemon for a slightly different twist, and I might try roasted carrots and roasted potatoes (for dad) as well.

There’s not much to cooking corned beef in the crockpot; just put enough water to barely cover the meat, add spices and a few onions, and let it simmer on low for 6-7 hours, or until the meat is tender enough to pierce easily with a fork.

Serve with cabbage, carrots (and even a few potatoes if you’re not on a diet) for a great Irish American meal that definitely tastes good, especially if you only eat it once a year! If you wanted to add something else, this would taste great with Pureed Cauliflower with Garlic, Parmesan, and Goat Cheese or 100% Whole Wheat Brown Soda Bread.

Slow Cooker Corned Beef with Veggies and Horseradish Sauce

This Slow-Cooker Corned Beef with Veggies and Horseradish Sauce is something I make every year for St. Patrick’s Day!



  • 1 corned beef, 3-5 pounds (flat cut preferred)
  • 1 bay leaf
  • 1 head garlic
  • 3 whole cloves
  • 10 peppercorns
  • 5 allspice berries or small pinch ground allspice
  • 1 whole onion
  • 1 head cabbage, cut in 4 pieces
  • 2 cups carrots, cut up if large
  • (You could add onions if you wish)

Horseradish Sauce Ingredients

  • 3/4 cup mayo, lite mayo, or sour cream (or use a combination)
  • 2-3 T cream style horseradish


  1. Trim all visible fat from corned beef and place in bottom of crock pot.
  2. Cut onion into a couple of pieces and place around the meat.
  3. Pour in enough water to cover, add spices and cook on low for about 6-7 hours.
  4. When you can pierce corned beef fairly easily with a fork, pour out most of the liquid (saving it if you want to make the “au jus” sauce below) remove onion, and add cabbage and carrots.
  5. Cook on high about 1 hour, or until veggies are tender. (If you’re hanging out in the kitchen you might want to put the carrots in for a while, then add the cabbage.)
  6. You can remove the meat for part of the cooking time if you feel it is getting too done.
  7. Optional – To make a flavorful “au jus” type sauce to serve with the meat: While veggies are cooking, skim reserved cooking liquid and simmer to reduce by half or more. (I taste it to decide how concentrated to make it. It can get too salty if you simmer too long.) If you are needing extra comfort, you can whisk a tablespoon or so of butter into the au jus when it has been reduced to the desired consistency. I find I don’t need that any more, but it does give a good flavor.
  8. Horseradish sauce: Combine mayo, sour cream, or a mixture with horseradish and whisk together. I would advise starting with a smaller amount of horseradish and tasting, then adding more until you get the amount you prefer. (You can replace some of the mayo or sour cream with milk if you want a thinner sauce.)
  9. When veggies are done to your liking, cut corned beef across the grain and serve with vegetables and sauce.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Corned beef isn’t really South Beach Diet approved, so this Slow Cooker Corned Beef is a once-a-year treat if you’re following that diet, but corned beef and cabbage (without the carrots) would be great for most low-carb eating plans. This could be a whole meal by itself, but if you have non-South Beach Dieters in the family, you might want to cook potatoes in with the other vegetables for them.

  1. Sadly, I guess not everyone has a great dish. Mine was a failure,& I followed the recipe exactly. Bought the flat cut meat,red potatoes,cabbage,carrots…etc. and it was disappointing. I made a vow that I will not make again..too much money & effort wasted. Don't have much of a clue what to do w/all the left overs..I love cb patties,but I'm not going to buy a grinder to mix up the meat..soup? don't see that,so I'm going to take it as a loss,and a lesson…next yr. I'll go out to a restaurant and have it…more affordable that way. Just to let anyone/everyone know not all recipes turn out winners.

    • I have made this at least 10 times and it's been great every time. So I don't have any idea why yours was not a success. But I know the recipe is okay, because as I said I've made it at least 10 times.
