- 4 carrots, peeled and chopped into 2–3” chunks
- 6–8 small-medium size red potatoes (unpeeled)
- 1 large yellow onion, rough chopped
- 2–3 lb flat cut corned beef brisket with seasoning packet
- 1 14.9 ounce can of Guinness Draught Stout
- 3 tablespoon yellow mustard
- 1/2 – 3/4 cup brown sugar, divided *See note
- 2 tablespoon grainy mustard
- 1 tablespoon Worcestershire sauce
- 1/4 cup water
- 1 teaspoon horseradish
- 1/2 teaspoon salt
- 1/2 teaspoon pepper
- 1/2 cup honey
- 1 medium size head of cabbage, cut into wedges
Make the Corned Beef
- Rinse the corned beef under cold water and pat dry. Place the corned beef, fat side up in a 6 quart (or bigger) crock pot. Add the potatoes, onions and carrots around the beef. In a small bowl, mix the yellow mustard and seasoning packet together. Spread the mustard mixture all over the top of the corned beef. Pour the beer around the beef. Sprinkle 1/2 cup brown sugar over top the beef, veggies and beer. Cook on low for 7 hours.
- Remove the lid and add the cabbage wedges. Cook for 2 more hours. Remove the meat from the crock pot and set aside. Place a tent foil on top. Using a slotted spoon, scoop out the veggies and place in a bowl.
Guinness Reduction Sauce
- Place a sieve/strainer over top a medium pot and strain the juices into the pot. Place the pot over high heat. Bring to a boil, add in the remaining 1tablespoon – 1/4 cup of the remaining brown sugar (depends on how sweet you want your sauce. Start off with a little, taste and adjust from there), water, horseradish, salt, pepper, grainy mustard, Worcestershire, honey and mix. Bring to a boil and then reduce the heat to a simmer to reduce the sauce by half and it starts to thicken. ~35-50 minutes.
- Slice the meat against the grain and serve with the reduction sauce over top with a side of potatoes, carrots and cabbage.
With regards to the brown sugar, keep in mind that reducing the Guinness will render the sauce sweet however I still add up to the last 1/4 cup of brown sugar personally as I found it was a tad ‘bitter’ without it. My advice is to start off with 1 tablespoon of brown sugar, taste the sauce as it reduces and add more if necessary.
