Ingredients You’ll Need
- 1 (3-4 pounds) corned beef brisket: The star of the dish, tender and flavorful. Select high-quality brisket for the best taste.
- 1 large head cabbage, cut into large wedges: Adds sweetness and crunch; savoy cabbage is a lovely alternative if you prefer.
- 4 large carrots, chopped into large chunks: Sweetens the dish and adds color. Feel free to substitute with parsnips for a unique flavor.
- 6-8 medium potatoes (red or Yukon Gold), halved or quartered: Their creaminess complements the meal. Choose your favorite, but avoid waxy varieties.
- 1 large onion, thinly sliced: Enhances flavors with its natural sweetness; use yellow onions for a balance of sweetness and acidity.
- 4 cloves garlic, roughly chopped: Adds aromatic depth; increase based on your personal garlic preference.
- 4 cups beef broth: Provides rich flavor; homemade or low-sodium options help control saltiness.
- 1/4 cup apple cider vinegar: The acidity brightens the flavors and tenderizes the beef.
- 2 bay leaves: Impart a subtle aromatic quality; omit them if you’re short on time.
- 1 teaspoon mustard seeds (if not in seasoning packet): For an added layer of flavor; can substitute with dry mustard.
- 1 teaspoon black peppercorns (if not in seasoning packet): Helps enhance the overall flavor profile; can use pre-ground if needed.
- 1 teaspoon dried thyme: Adds earthiness and warmth; fresh thyme would be even better if available.
- Salt and black pepper to taste: Essential for seasoning. Taste before adding to avoid over-salting.
- 2 tablespoons unsalted butter (for mustard cream sauce): Creates a luxurious sauce; using salted butter can alter the seasoning a bit.
- 2 tablespoons all-purpose flour (for mustard cream sauce): Thickens the sauce; substitute with cornstarch for a gluten-free option.
- 1 1/2 cups milk (for mustard cream sauce): The base for the creaminess; any milk like almond milk or oat milk works fine.
- 2 tablespoons Dijon mustard (for mustard cream sauce): The tanginess pairs perfectly with the beef; feel free to use whole grain mustard if preferred.
- 1 tablespoon stone-ground mustard (for mustard cream sauce): Adds texture; regular Dijon can work as a substitute.
- 1/2 teaspoon white wine vinegar (for mustard cream sauce): Brightens the sauce; lemon juice can offer a similar zesty impact.
How to Make Corned Beef and Cabbage | Traditional St Patrick’s Day Dinner
Prepare the Beef: Unwrap your corned beef brisket, rinsing it thoroughly under cold water to eliminate excess brining solution. Pat it dry with paper towels before placing the beef fat-side up into your slow cooker. If your brisket includes a seasoning packet, sprinkle it generously over the top. For additional flavor, incorporate 1 teaspoon of mustard seeds and black peppercorns directly into the pot, alongside 2 bay leaves.
Add Aromatics: Thinly slice your onion and roughly chop the garlic, scattering them around the brisket. This step enhances the rich aromas wafting through your kitchen. Pour in about 4 cups of beef broth and 1/4 cup of apple cider vinegar around the brisket, ensuring they meld together. Cover the slow cooker, then set it to cook low for 6-8 hours, or on high for 3-4 hours, until the brisket is fork-tender.
Prep the Vegetables: As the beef cooks, prepare your vegetables approximately 2-3 hours before finishing if using low heat, or 1 hour before if using high heat. Cut 1 large head of cabbage into wedges, peel and chop the 4 large carrots into chunks, and halve or quarter your potatoes. This prep is crucial for perfect texture.
Combine Everything: Gently arrange the cabbage, carrots, and potatoes around the corned beef in the slow cooker. Ensure they are partially submerged in the aromatic cooking liquid, stirring gently to combine while being careful not to disturb the brisket too much. Replace the lid and continue to cook until the vegetables are fork-tender but still maintain their shape.
Slice the Beef: Once everything is cooked to perfection, carefully remove the brisket from the slow cooker and let it rest for about 10-15 minutes on a cutting board. This resting period is essential for retaining juices when slicing. At this point, you can strain off some of the cooking liquid for serving.
Make the Cream Sauce: In a small saucepan, melt 2 tablespoons of butter over medium heat. Whisk in 2 tablespoons of all-purpose flour to form a roux, cooking it briefly until golden and fragrant. Gradually whisk in 1 1/2 cups of milk, stirring continuously until the mixture thickens. Lower the heat, then stir in 2 tablespoons of Dijon mustard, 1 tablespoon of stone-ground mustard, and 1/2 teaspoon of white wine vinegar. Season with salt and black pepper to taste, continuing to stir until smooth and creamy.
Serve: Slice the rested corned beef against the grain into thick, beautiful slices. On a large platter or individual plates, artfully arrange the sliced beef next to the perfectly cooked cabbage wedges, tender carrots, and creamy potatoes. Drizzle your warm mustard cream sauce over everything or serve it on the side, allowing your guests to customize their plates. For a beautiful finishing touch, sprinkle finely chopped parsley for that vibrant color.

Storing & Reheating
To store leftovers, allow the corned beef and cabbage to cool completely before transferring them to an airtight container. Refrigerate for up to 4 days. If you’re looking to keep it longer, freeze the dish in a freezer-safe container for up to 3 months. When you’re ready to enjoy, reheat in the microwave or on the stovetop over medium heat until warmed through, stirring gently. Keep in mind that texture may slightly change upon reheating, but a splash of broth can help regain moisture.
Chef’s Helpful Tips
- To prevent the beef from becoming too salty, be sure to rinse it thoroughly before cooking.
- Cooking the vegetables for too long could lead them to lose their color and texture; add them at the appropriate time.
- Use room temperature ingredients when making the mustard cream sauce for smoother results.
- For added depth of flavor, consider adding a splash of stout or red wine to the cooking liquid.
- If time permits, let the dish cool before slicing to allow juices to redistribute throughout the beef for maximum flavor.
It’s a beautiful thing when comfort food can be so easy and rewarding. The richness of corned beef combined with the vibrant colors of the vegetables creates a dish that’s as pleasing to the eye as it is to the palate. Remember, cooking is a personal journey, and you can easily customize this recipe to make it your own. Don’t shy away from experimenting with the mustard sauce or even trying different vegetables. You might just find a new favorite! Gather your loved ones, serve this comforting staple, and savor every delicious bite.
