The absolute BEST Crock Pot Guinness Corned Beef and Cabbage recipe with Guinness reduction sauce!  Fall-apart corned beef that melts in your mouth!

Corned Beef & Cabbage with a Guinness Reduction Sauce

Married to Mr. Fantabulous and him being a GINORMOUS beer snob I’ve been ‘coerced‘ to try umpteen different types with the line of “baby, maybe you’ll like this one.  If you loved me, you’d try it.” 

My response is always “..and if you loved me you’d remember that we’ve yet to find one that I like or can even get past the smell. If YOU loved me you’d figure out how to pick up your clothes, put the dishes in the dishwasher and figure out that vacuuming CAN be fun.” Sounds fair, right? 

TKW Family Love

This is by far the best corned beef recipe we’ve ever done, and it’s been our go to for years since we found it.

I brine my own brisket rather than using a store bought, which I highly recommend to anyone who hasn’t done it yet if you like to dabble in that sort of thing.

We also add one mini shooter of Jameson to Irish it up a little more, though I don’t know it’s really noticed one you reduce the juice down to a glaze. We freeze the extra glaze and add to other meat since my wife loves it so much.

I’d give this recipe six stars if I could!

But like the good wife I give in to spousal pressure, take the god-awful sip, make the funniest yucky squinched-up-7-year-girl-I’m-gonna-die face and then say that I still hate it while he chuckles at my response.

I LOVE Cooking and Baking with Beer!

Guinness Corned Beef & Cabbage2

It’s funny though as I don’t like the taste of beer straight from the bottle but I LOVE the flavor of it when it’s cooked or reduced. 

The flavors tend to be mellow and almost create this magical taste. I use beer quite often in various chocolate cakes (reduced stout in a chocolate cake is EPIC!) as well as in brownies. Heck, I’ve even made beer syrup and used it in ice cream.

From Stovetop to Crock-Pot For Corned Beef

Now I’ve been making corned beef & cabbage since I was little.  I can remember my Mom making it on the stovetop for hours on end. 

When she got her first crockpot you would have thought Sweet Baby Jesus delivered it to her personally!  From then on, corned beef was made in the crock.  And as always it had a beer in it. 

TKW Family Love

Absolutely amazing! I have never cared for corned beef before this recipe. I would HIGHLY recommend that everyone try it.

What about making Corned Beef in the Instant Pot?

I got you guys! I have the instant pot recipe already posted. You can’t go wrong with either method, to be honest!

The beer matters in this recipe

Being married to a beer snob, we always have a ton on hand to work with. I tried more than my fair share. The best beer I’ve found for this recipe is Guinness Draught Stout. As it cooks, it adds an incredible depth of flavor.

What I did find was that the stout beers—those darker beers—infused such an intense flavor when cooked that you find yourself unable to stop eating the beef (case in point last night when I made this recipe). 

If you’re not a beer drinker, like I am, you can buy single cans or bottles in most grocery stores, so you don’t have to feel concerned about having to buy a whole case.

Ingredients needed to make THE BEST Guinness Corned Beef

  • Flat Cut Corned Beef Brisket with seasoning packet  – flat is best for slicing
  • Veggies – carrots, cabbage, potatoes,  and onions
  • Beer – Guinness Draught Stout
  • Seasonings & liquids – mustard, Worcestershire, water, horseradish, salt, pepper, and honey
  • Sugar – This depends on how sweet you like your meat and sauce. Start with less for the sauce, as you can always add more if you need

How to Cook The Best Corned Beef with Beer!

TKW Family Love

So good! The sauce was just incredible and even my toddler approved of the meal!

Hayley


It’s super simple to make: Throw most of it in the crockpot and let it cook all day!

  1. Pat your meat dry and place it fat side up in the crockpot. Add the carrots and potatoes around the meat.
  2. Mix the mustard and seasoning packet and spread it all over the meat. Next, add the beer around the meat (not on top).
  3. Sprinkle some sugar over the top of it all and cover.
  4. Cook on low for 7 hours.
  5. Add the cabbage and cook for another 2 hours.

How to Make Guinness Reduction Sauce

  1. Once the meat is done, strain the juice out and place it in a pot over high heat.
  2. Once boiling, add in some sugar and the rest of the ingredients. *Remember this is where you want to start in small amounts
  3. The sauce can take 30-55 minutes to reduce. This depends on how liquid your beef is.

Difference Between Corned Beef Cuts – Flat and Point

There are a few different cuts of corned beef brisket, but the two most popular are Flat Cut and Point Cut.

TKW Family Love

This is undoubtedly the BEST corned beef I’ve ever eaten. I’m not a fan of mustard because I have an ulcer but the mustard smear on the corned beef made the dish, with a little help from the Guinness. This cooked mustard smear never irritated my ulcer and the flavor is to die for. Next year I’m making twice as much and inviting my friends over. They have to taste this. My complements to this dish’s creator!

Flat Cut Corned Beef

The flat cut is leaner, though it still has a fat cap layer that helps keep the meat moist. You want to use this when you want to slice your corned beef and lay it nicely on the plate or sandwich.

Point Cut Corned Beef

The most obvious difference is the pointed tip at one end. This type of cut has more fat, so when you cook it, it comes out super tender and juicy. This is perfect for shredding it for nachos and sandwiches.

Uses for Corned Beef Leftovers

  • Irish Nachos: Pub-Style Irish Nachos are crispy thin potatoes topped with 3 types of cheeses, corned beef, sauerkraut, green onions and beer cheese.
  • Reuben Nachos: Simply shred the meat and layer it on the nachos with some Irish cheddar, green onions, and braised cabbage/slaw. You can even drizzle some of the Guinness sauce on the side!
  • Pulled Corned Beef Sliders: These paired with Irish Cheddar – EPIC!
  • Reuben Sandwiches: The hardest part is deciding if you want mustard of 1000 island dressing.
  • Reuben Tart: tart dough filled with sauerkraut, corned beef, and cheese!
  • Reuben Pizza: need I say anymore?
  • Cheesy Reuben Dip: all the great flavors of a Reuben sandwich but in a dip!

The absolute BEST Guinness Crock Pot Corned Beef & Cabbage with Guinness Reduction Sauce

  • Author: The Kitchen Whisperer
  • Prep Time: 15
  • Cook Time: 9 hours
  • Total Time: 10 hours
  • Category: Beef
  • Method: CrockPot
  • Cuisine: Beef

Ingredients

  • 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

Instructions

Make the Corned Beef

  1. 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.
  2. 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

  1. 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.

Serve

  1. Slice the meat against the grain and serve with the reduction sauce over top with a side of potatoes, carrots and cabbage.

Notes

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.

    OMG thank you so much for sharing this recipe. I made this it is by far the best corned beef I have ever had. The sauce was amazing. Although I have to admit i saved some juices for leftovers and I didn’t strain it, I like all the spices and bits. Great recipe ☘️

    I have a question it might be silly but humor me. How do you keep everything hot while making the sauce?

      No silly questions Rick 🙂 Put it in a dish and cover it with foil with a little bit of liquid and place in the oven on “warm” while the sauce is being made.

      I saved a bit of the juice added a bit of beef broth and water to keep mine in the crockpot while making the sauce. This is an amazing recipe.
