This slow-cooked corned beef and cabbage meal delivers deep comfort and big flavor with minimal hands-on time. Brisket gets a golden sear, then simmers for hours with garlic, onion, and spices. Toward the end, carrots and cabbage soak up the savory broth, while oven-roasted red potatoes give you that crispy edge. A swipe of horseradish sauce and a sprinkle of herbs tie it all together. It’s a go-to for St. Patrick’s Day at our house, and a winter favorite that never fails to fill the kitchen with cozy smells.
I threw this together one evening after work with just what I had on hand. It turned out so well, my family begged for it again the next week.

Irresistible Ingredients
- Roasted red potatoes: They get crispy in the oven and stay firm. Pick smooth ones without blemishes
- Horseradish sauce: Adds bright heat and cuts the richness. Look for a fresh kind in the refrigerated section if possible
- Parsley or chives: Adds freshness and color. Choose bunches that smell fresh and have no wilting
- Bay leaves: Bring depth to the broth. Choose dried ones that still snap when bent
- Whole peppercorns: Give a subtle bite. Use freshly cracked if you like more kick
- Kosher salt: Essential to season the broth and cabbage. Helps bring out the natural flavors
- Butter: Makes cabbage silky and rich. Stick with real butter for best results
- Oil: Use a high-heat option like avocado or canola to get that perfect sear on the beef
- Onion: Adds sweetness as it simmers. Use firm, tight-skinned onions
- Garlic: Infuses everything with mellow heat. Avoid soft or sprouting cloves
- Carrots: Their natural sweetness balances the brine. Thick ones cook better and don’t go mushy
- Green cabbage: Holds its shape well when cooked. A heavy head means tightly packed fresh leaves
- Fresh thyme: Adds aromatic notes. Fresh sprigs work best but dried can be used in a pinch
- Beef broth: Forms a rich base for the whole dish. Go for low-sodium to adjust seasoning later
- Whole grain mustard: Brings tang and texture. Look for one with visible mustard seeds for best flavor
- Corned beef brisket: Choose a four-pound flat cut for even cooking. A good balance of fat and meat makes for tender slices
Simple Step-by-Step Directions
- Sear the Beef:
- Get your pan hot with a splash of oil. Set the brisket fat-side down and let it brown deeply without moving it. Flip once and brown the other side. This step builds key flavor
- Deglaze the Pan:
- Pour in the beef broth and mustard right into the hot pan. Scrape up every browned bit and let it simmer. Pour this rich liquid over the seared brisket in your cooker
- Layer the Vegetables and Spices:
- Tuck thick onion slices and crushed garlic around the beef. Scatter thyme sprigs, bay leaves, and peppercorns on top. Add any spice packet that came with the meat
- Slow Cook the Beef:
- Cover everything and let it go low and slow for six to seven hours. You’re aiming for beef that falls apart when you touch it with a fork
- Add the Carrots:
- About two hours from the end, nestle the carrot chunks on top. They’ll cook just enough to be soft but not overdone
- Prepare and Sauté the Cabbage:
- Slice the cabbage, discard the core, and sauté with butter and salt in a big pan. Cook it until just wilted and still a bit crisp
- Finish with Cabbage in Cooker:
- Once the meat and carrots are nearly ready, pile the cooked cabbage on top. Let it steam with the other ingredients for half an hour to an hour so it absorbs all the savory juices
- Roast the Potatoes:
- Toss your red potatoes with oil and roast them in the oven until they’re crisp and golden. This keeps them from turning soggy like they might in a slow cooker
- Plating and Serving:
- Let the brisket rest on a cutting board, then slice across the grain. Use a slotted spoon for the veggies and plate everything up with the roasted potatoes. Add herbs and horseradish sauce right before serving

Tips for Leftovers
Store sliced beef and vegetables in airtight containers in the fridge for up to four days. A splash of broth when reheating helps everything stay moist. You can freeze portions, though the cabbage may get a bit soft. Still tastes great and works wonderfully in sandwiches or hash
The smell of butter sizzling with cabbage reminds me of my grandma’s tiny kitchen. She’d laugh as we all tried to sneak bites straight from the pan. That buttery aroma alone still pulls me back
Swaps You Can Make
No brisket on hand? Use a chuck roast—it’s a bit different but still tender and rich. If you’re out of whole grain mustard, try Dijon or even spicy brown. Want to avoid potatoes? Cooked cauliflower or parsnips do the trick. You can also add rutabaga for an earthy bite
Ways to Serve
Lay everything out on a platter or board for family-style serving. Add slices of Irish soda bread if it’s a holiday meal. Leftovers make killer sandwiches with mustard and pickles on rye. Cold or warm, they hit the spot
Story Behind the Dish
Corned beef and cabbage is more of an Irish-American tradition than something you’d actually find on Irish tables. Immigrants in the U.S. made it a celebration meal using budget cuts like brisket and hearty cabbage. Today, it’s a dish that brings everyone together, especially in March, over warm plates and shared stories
