Slow Cooker Guinness Corned Beef

Sunday, April 10, 2016
Slow-cooked corned beef with Guinness beer is one of the most flavorful ways to cook this meat fork tender! I just love the ease and flavors from making this in a slow cooker! It gets so tender you can cut it with a fork!

I love being Irish for a day so much and St. Patrick's Day celebration foods, I really wonder why I wait once a year to have this tender fabulous corned beef!

I really love it like this, this is a classic recipe for sure. I was never a big fan of this cut of meat because it's can be a tougher cut, but in the slow cooker with stout beer, it's fabulous.

I tried many recipes but nothing compares to the flavors and tenderness with this recipe. It is now my go-to recipe and I always go back to cooking it on low heat and slow and it's the best method of cooking this brisket.

St. Patrick is was a real person, and he lived some time in the fifth century A.D. and was British, not Irish.

St Patrick's Day, on March 17 is celebrated with all kinds of green beer and the culture is popular here in the United States.

American's celebrate with foods for the day that are Irish-inspired, like corned beef and cabbage, shepherd's pie and Irish soda bread.

Whatever vessel you choose to cook this in, the secret to a tender corned beef is the slow cooker method.

It must be slowly cooked to break down the brisket meat or slow and low on top of the stove if you want it to be fork-tender.

My Cooking Thoughts

In my experiences, the best results will come from making sure the meat is slow-cooked.

This was full of flavors from the packet and just melts in your mouth, this corned beef is just delicious.

Cooking Methods

  1. Slow Cooker: Add the corned beef and ingredients as directed slow cook on high 6 to 8 hours low 8 to 12 hours.
  2. Instant Pot or Pressure Cooker Mode: Place the corned beef in the pot, set for 1 hour and 10 minutes on pressure cook mode for 2 to 3 lbs. Close valve. Let rest after cooking 10 minutes before releasing steam.
  3. Oven: in a covered dutch oven add all the ingredients and set the oven on 275 for 5 hours.
  4. Stovetop: In a large covered deep 8-quart saucepan add all ingredients, simmer on low heat for 4 hours. Continue to add more beer, water or apple juice and check to see if the liquid is evaporating.

  • Below I give many suggestions.
  • You can put this all together or make the vegetables any way you want.
  • The slow cooker is always the way to go on cooking this cut of meat.
  • The stout beer gives it the added richness this meat needs however you can use apple juice in its place.

Vegetables and Additions

I recommend cooking the vegetables separately and then add them at the end.

Just boil the carrots, potatoes, and cabbage until soft then toss with some olive oil, granulated garlic to taste, salt, pepper or some butter around 2 tablespoons toss while hot.

You can serve the vegetables pre-cooked or just add to the slow cooker to whatever pot you're using.

I used cabbage, carrots and tiny white potatoes and boiled them first.

I add them to the slow cooker at the end of cooking the meat just to coat the vegetables with the meat and brisket flavors.

  • I use a slow cooker for cooking preferably 6 to 8 hours on low or pressure cooker mode 1 hour and 10 minutes for 3 lbs.
  • Using the slow cooker, sometimes vegetables tend to take a longer time to cook don't come out as tender.
  • I prefer to boil them separately or even bake them on a large cooking sheet with butter, salt, and pepper.
  • You can decide how you want to cook your vegetables. I love cabbage, carrots, and potatoes soft and usually cook them separately.
  • Throw in more or less salt and pepper to taste corned beef is salty and usually doesn't need more seasoning, however, the vegetables cooked in another pot need to be seasoned.
  • Use a good grade stout beer for this recipe, apple juice or water.

Cooking the Vegetables

This is just a guideline on how we like ours cooked and vegetables

Corned beef with cabbage potatoes and carrots can all go in the crockpot/ slow cooker or pressure cooker, cooked on the stovetop or in a dutch oven-baked, with the seasoning packet and any other spices you prefer, that is the original authentic recipe, all in one pot.

Usually, they all go into one pot, I am not a fan only because I like the fresh colors of the carrots, cabbage, and potatoes to stay whiter so I boil mine separate in saltwater I have done this both ways and the taste difference is that the packet gives the cabbage the same flavors as the meat.

Again, we like our vegetables softer than most with a hint of flavor and not overpowering as the seasoning packet takes over.

The Real Story

The Irish Americans transformed St.Patrick's Day from a religious feast day to a celebration of their heritage and homeland.

With the celebration, came a celebratory meal.

Instead of corned beef and cabbage, the traditional St. Patrick's Day meal eaten in Ireland is lamb or bacon.

Why is it Corned Beef Red and Some Gray

The reason some briskets are redder than others is because of the brine salt that is used.

Corned beef is brined or cured using saltwater or sodium nitrite mixture, which fixes the pigment in the meat and causes it to be pink in color.

That's why corned beef remains pink after cooking

The red brisket is the traditional flavor old-time New Englanders always recognize.

Another Method

There is another method used to brine the corned beef that stays gray in color.

The reason for this color, it is cured in a saltwater brine for two weeks or more.

This brine contains no preservatives, so the grey corned beef is a great option for those who are looking to avoid nitrates and nitrites.

Because the brine isn’t seasoned, the grey corned beef can also be seasoned to your tastes.

Flat Cut or Point Cuts?

Point Cut is good for shredding, but for corned beef, I always choose the flat cut for slicing.

It still has a good amount of fat on the bottom to keep the meat moist.

Either way, they are both tasty, the flat cut is usually just more expensive.

The easiest tender corned beef I ever ate or made and so delicious. Perfect for St. Patrick's Day and leftover, if there are any, are fabulous for Reubens!


  • 1- 4 pound or larger corned beef brisket and seasoning packet
  • 2/3 cup brown sugar ( I have used less before depending how big the roast is, use 1/4 cup for less than a 4-pound beef)
  • 1 bottle stout beer Irish beer 12-ounce bottle
  • Optional: 1 head of cabbage cut up,1 cup finger carrots and 4 potatoes cut in cubes
  • see note below


  1. Place beef in the slow cooker, rub with the sugar then pour the beer on top. If using vegetables add on top of the meat.
  2. Cook on low 6 to 8 hours or on high 4 to 6 hours. Make sure you test this with a fork that it pulls apart easily and is tender.
  3. Note: I boil my carrots, cabbage and potatoes separately until tender and add to the pot 1 hour before the corned beef is completed.
