Ingredients
  

Main Ingredients
  • 1 Corned Beef Brisket (3-4 lbs, flat cut, with spice packet included, if available)
Aromatics & Liquid
  • 1 large Yellow onion quartered
  • 3-4 cloves Garlic smashed
  • 2 large Carrots roughly chopped
  • 1 Bay leaf
  • 8 cups Water or low-sodium beef broth enough to cover brisket
  • 1 cup Guinness stout or apple cider optional, for flavor depth
Pickling Spices (if not using included packet)
  • 1 tbsp Whole black peppercorns
  • 1 tbsp Coriander seeds
  • 1 tsp Mustard seeds
  • 1/2 tsp Whole allspice berries
  • 4-5 Whole cloves
  • 1/2 tsp Red pepper flakes optional, for a kick

Equipment

  • Large Dutch oven or stockpot with a lid
  • Sharp carving knife
  • Cutting board
  • Measuring cups and spoons

Method
 

Preparation
  1. Remove the corned beef brisket from its packaging. Rinse it thoroughly under cold water to remove excess brining solution and salt. Pat dry with paper towels.
Cooking
  1. Place the rinsed brisket in a large Dutch oven or stockpot, fat-side up. If your brisket came with a spice packet, sprinkle the contents over the brisket. If not, add the pickling spices (black peppercorns, coriander seeds, mustard seeds, allspice, cloves, red pepper flakes) directly to the pot.
  2. Add the quartered onion, smashed garlic cloves, roughly chopped carrots, and bay leaf around the brisket in the pot. Pour in enough water or beef broth to completely cover the brisket. If using, add the Guinness stout or apple cider now.
  3. Bring the liquid to a rolling boil over high heat. Once boiling, reduce the heat to low, cover the pot tightly, and let it simmer gently for 3 to 3.5 hours, or until the brisket is fork-tender. The internal temperature should reach 160°F (71°C), but tenderness is the key indicator for corned beef.
Resting and Serving
  1. Once tender, remove the brisket from the pot and place it on a cutting board. Tent it loosely with foil and let it rest for at least 15-20 minutes. This allows the juices to redistribute, ensuring a more tender and flavorful slice.
  2. After resting, slice the corned beef against the grain into thin pieces. Serve hot with traditional accompaniments like boiled cabbage, potatoes, carrots, or mustard.

Notes

For best results, allow the corned beef to simmer gently; boiling too vigorously can make it tough. The cooking liquid (broth) can be strained and used as a flavorful base for soup or to moisten the sliced brisket. Leftovers can be stored in an airtight container in the refrigerator for 3-4 days. It's delicious in sandwiches or hash.
