Ingredients

For the Slow Cooker

1 piece corned beef brisket about 3–4 pounds
3 cups water or low-sodium broth

Honey Mustard Glaze

0.25 cup yellow mustard
2 tablespoons honey
1 tablespoon white vinegar
1 teaspoon prepared horseradish
1 teaspoon dried tarragon
0.5 teaspoon salt adjust to taste
0.5 teaspoon black pepper adjust to taste

Method

Slow Cooking the Corned Beef

Place the corned beef brisket into the slow cooker and add water or broth until it reaches about halfway up the meat.
Cover and cook on low heat for 12 hours, or until the beef is very tender and easily pierced with a fork.

Glazing and Finishing

Preheat the oven to 400°F (200°C). Remove the cooked corned beef from the slow cooker and place it in an oven-safe baking dish.
In a bowl, mix the mustard, honey, vinegar, horseradish, dried tarragon, salt, and black pepper until well combined.
Brush the glaze generously over the corned beef, cover the dish with foil, and bake for 45 minutes.
Remove from the oven and let the beef rest for 15 minutes before slicing against the grain and serving.

Notes

Cooking time may vary slightly depending on the thickness of the brisket.
For a deeper glaze flavor, uncover the beef for the last 10 minutes in the oven.
