Step 1

Rinse the corned beef and pat it dry (this is important to get a good sear).

Step 2

Preheat a dutch oven over high heat then add the oil. Add the corned beef roast and brown it well on all sides.

Step 3

Add the Guinness to the pot plus enough water to the cover roast completely. Add the onion, garlic, bay leaf, cinnamon, cloves, allspice and pepper. Bring it to a boil.

Step 4

Reduce the heat to low, cover the pot, and simmer for three hours. (Low temperature should keep it at a very gentle simmer; if it doesn't, increase the heat slightly).

Step 5

Add the carrots and potatoes and simmer for another 20 minutes. Add the cabbage and simmer 10 minutes more.

Step 6

Remove the meat, veggies and potatoes to a serving platter. Slice the meat against the grain – it will be very tender – and enjoy it with a nice cold bottle of Guinness!

Step 7

Press “Saute” to preheat your IP and set the temperature to “More”. When the word “hot” appears on the display, add the oil. Brown the corned beef brisket well on all sides (cut it in half if necessary to fit on the bottom of the pot). Add the Guinness draught to the pot, then enough water to cover the meat completely.

Step 8

Close and lock the lid of the IP. Press “Manual” and immediately adjust the timer to 70 minutes. Check that the cooking pressure is on “high” and that the valve is set to “Sealing”.

Step 9

When the time is up, allow the pressure to release naturally for 15 minutes, then use the “Quick Pressure Release” to release any remaining pressure. Carefully remove the lid, then remove the corned beef, place it on a cutting board, drizzle it with about 1/2-1 cup of the cooking liquid, then tent it with foil.

Step 10

Discard all but 2 cups of the liquid that remains in the pot. Add the potatoes, carrots, onions, and cabbage. Close and lock the lid of the Instant Pot. Press “Manual” and immediately adjust the timer to 3 minutes.

Step 11

When the time is up, release the pressure using “quick pressure release” and remove the lid. Continue with the recipe at step 5.
