Ingredients

• 4 lbs corned beef brisket
• 4 cups water
• 2 cups beef broth
• 1 onion, quartered
• 4 carrots, peeled and halved
• 2 bay leaves
• 1 tbsp whole black peppercorns
• 4 cups green cabbage, shredded
• 2 lbs russet potatoes, peeled and cubed
• 6 tbsp butter
• 1 cup milk
• 4 scallions, thinly sliced
• 1 tsp salt
• 0.5 tsp black pepper
• 2 tbsp parsley, chopped (optional, for garnish)

Directions

Step 1

Preheat your oven to 325°F (165°C).

Step 2

Place the corned beef brisket in a large oven-safe Dutch oven or roasting pan. Add 4 cups of water, 2 cups of beef broth, the quartered onion, halved carrots, bay leaves, and whole black peppercorns.

Step 3

Cover the Dutch oven with a lid or aluminum foil, sealing it tightly, and transfer it to the preheated oven. Braise for 3.5 to 4 hours, or until the brisket is tender and easily pulls apart with a fork.

Step 4

While the brisket cooks, prepare the colcannon. Start by boiling the cubed potatoes in a large pot of salted water until fork-tender, approximately 20 minutes.

Step 5

In a separate pan over medium heat, melt 2 tablespoons of butter and sauté the shredded cabbage until softened, about 5 minutes.

Step 6

Drain the potatoes and return them to the pot. Add 4 tablespoons of butter, warmed milk, salt, and black pepper. Mash until smooth and creamy.

Step 7

Stir the sautéed cabbage into the mashed potatoes along with the sliced scallions. Mix until well combined. Adjust seasoning with additional salt and pepper if needed.

Step 8

Once the brisket has finished braising, remove it from the oven and allow it to rest for 10-15 minutes before slicing against the grain.

Step 9

Serve slices of the braised corned beef alongside a generous scoop of colcannon. Garnish with chopped parsley if desired.
