Mouth-Watering Guinness Braised Corned Beef (Instant Pot)

Highly-marbled Wagu makes the most luscious corned beef

Corned Beef in the Instant Pot is one of those recipes that works great. The recipe is simple, the meat cooks perfectly, and it tastes great. US markets are inundated with corned beef in March. The best we have found is the one at our local Costco, made with American Wagyu Beef. This meat is highly marbled, like Kobe beef. The marbling makes this a super tender and juicy corned beef. This mouth-watering Guinness braised corned beef is something you’re going to want to make again and again (and again).

I love making corned beef in the Instant Pot because the closed, high-moisture pressure keeps the meat really juicy. The meat is infused with the spices and flavors added to the pot when it cooks (check out our carnitas recipe for another example). In this recipe I keep it simple: an onion, a few garlic cloves, celery stalks, and some Bay leaves. Finally, for the braising liquid I use a can of Guinness! Of course, you can substitute just about any other stout beer you prefer, but my BF and I are partial to the black stuff!

Rest and cool the cooked roast to slice super thin

Serving Corned Beef

There are tons of ways to use your mouth-watering guinness braised corned beef, of course, but one of my new favorites is to use it to make Reuben Tacos! I use street-sized flour tortillas, and top them with sauerkraut, shredded gruyère cheese, and Russian dressing and top it with the crunchy red cabbage.

You can also go the traditional route, and cook cabbage, potatoes, onions, and carrots to serve with it. You shouldn’t cook the vegetables along with the meat. Corned beef in the Instant Pot cooks too long at high heat, subsequently your vegetables will be overcooked and mushy. However, you can take the meat out, and add the vegetables into the liquid in the pot and cook them quickly while the meat rests.

I always cook a big corned beef roast so I have lots of leftovers to eat! I hope you have fun with this easy, tasty recipe.

Wagyu corned beef makes this recipe extra moist and fall-apart tender, but all types of corned beef work equally well.

  • 4 lb Corned Beef Round American Wagyu Beef preferred
  • Spice packet from corned beef
  • 1 Yellow onion peeled and quartered
  • 4 cloves Garlic whole, peeled
  • 3 Bay Leaves whole
  • 4 stalks Celery (optional)
  • 1 can Guinness Draught Stout 14.9 oz can (or substitute any stout beer you prefer)
  • Russian Dressing (for serving)


  • Gather ingredients and tools.

  • Prepare the meat by removing it from packaging, saving the spice packet. Run under water to rinse quickly. Depending on the size of your Instant Pot and your corned beef, you may want to cut the meat into 2-3 chunks. For my 3.6 lb. roast, I cut it into two pieces since I want to be able to slice it later.

  • Put the meat in the bottom of your inner pot. I like to put the meat with the fat side down, if possible.

  • Quarter the onion and remove the skin. Chop the celery into a few large chunks as well. Peel the garlic cloves by smashing them with a knife on the cutting board to loosen the hard skin.

  • Add the vegetables to the pot with the meat, and sprinkle the spice pack into the pot. Drop in the bay leaves.

  • Pour the Guinness over top of everything.

  • Put the lid on the Instant Pot, close the vent, and set it to cook on manual, high, for 90 minutes. When the time is up, let it do a natural pressure release for 10 minutes.

  • Using a slotted spoon, carefully lift the corned beef out of the liquid and set it to rest on the cutting board. Strain the liquid and reserve.
    Note: the meat will be very tender and smell delicious, but refrain from slicing it until it has a few minutes to rest. Cutting before the meat has rested will cause the juices to run out and will give you a dry corned beef.

  • After 5-10 minutes resting, you can cut a few slices off. Try to only slice what you need for your meal. The meat is very soft and will tend to shred.

  • Put the rest of your corned beef into an airtight container and pour back in some of the juices from the pot. This will help keep it moist. Let it rest in the refrigerator overnight.

  • Once cooled and rested, you can use a sharp knife to carefully cut the corned beef into thin slices.

  • When reheated in a pan or in the microwave with some pot juices, the highly-marbled wagyu corned beef will literally melt apart.

  • Enjoy your sliced corned beef in sandwiches, tacos, or however you like! If you want to do corned beef and cabbage, you can cook the cabbage (and potatoes, carrots, etc.) separately, using the juices from the pot.
