Ingredient Notes

• Corned Beef Brisket – Typically comes pre-seasoned with a spice packet. Choose a cut with some marbling for the best flavor.
• Beef Broth or Water – Keeps the meat moist while cooking. Beef broth adds extra depth.
• Whole Grain Mustard – Adds tang and enhances the crust on the beef. Dijon works well, too.
• Garlic & Onion – Classic aromatics that infuse the roast with rich flavor.
• Carrots & Potatoes (Optional) – Cooked alongside the roast, they soak up all the delicious juices.
• Cabbage (Optional) – A traditional pairing with corned beef, adding a mild sweetness.

Step-by-Step Instructions

1. Prep the Meat

Rinse the corned beef under cold water to remove excess brine. Pat it dry with paper towels.

2. Set Up the Cooking Liquid

Place the brisket in a slow cooker, Dutch oven, or roasting pan. Pour in enough beef broth or water to come halfway up the meat. Add minced garlic and chopped onion.

3. Add Seasonings

Rub the top of the beef with whole grain mustard, then sprinkle on the included spice packet. If your corned beef doesn’t come with one, use a mix of peppercorns, mustard seeds, bay leaves, and cloves.

4. Cook Low and Slow

• Slow Cooker: Cook on low for 8-10 hours or high for 4-6 hours until fork-tender.
• Oven: Cover and roast at 300°F (150°C) for 3-4 hours, checking for tenderness.

5. Add Vegetables (Optional)

In the last 2 hours of cooking, add potatoes and carrots. Add cabbage during the last 30 minutes so it stays tender-crisp.

6. Rest and Slice

Let the beef rest for 10-15 minutes before slicing against the grain for the most tender texture.

Expert Tips for the Best Results

• Don’t Skip Rinsing – Corned beef is very salty. A quick rinse removes excess brine, ensuring the flavors aren’t overpowering.
• Cook Low and Slow – This cut of beef needs time to break down. The longer it cooks, the more tender it becomes.
• Slice Against the Grain – Cutting across the fibers ensures each bite is juicy and easy to chew.

Serving Suggestions

Corned beef roast pairs beautifully with:

• Mashed potatoes or buttered new potatoes for a creamy contrast.
• Irish soda bread to soak up the delicious juices.
• Dijon mustard or horseradish sauce for an extra zing.

Storage and Reheating Tips

• Refrigeration: Store leftover corned beef in an airtight container for up to 4 days.
• Freezing: Wrap slices tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
• Reheating: Warm in a skillet with a splash of broth or microwave in short bursts to retain moisture.
