Step 1

Insert the rack into the Instant Pot.

Step 2

Add the onion and garlic to the 6-quart Instant Pot distributing it evenly on the bottom.

Step 3

Remove the Corned Beef Brisket from the package, reserve the spice packet and rinse the meat thoroughly.

Step 4

Place the brisket in the Instant Pot on the lift-out rack (if there is a fattier side put that facing down) on top of the onions and garlic and sprinkle the seasonings evenly on top of the brisket and around it in the pot.

Step 5

Pour in the beer around the edges of the Instant Pot (to keep the spices on the brisket in place).

Step 6

Add the lid to the Instant Pot, select MANUAL High Pressure (default pressure setting) and 90 minutes.

Step 7

When done, do a QUICK RELEASE of the pressure, remove the brisket, brush the seasoning from the top of the brisket (more difficult to remove when it has cooled) and allow to rest.

Step 8

Add the potatoes (on the bottom) and carrots (on top of the potatoes) to the Instant Pot.

Step 9

Seal and select MANUAL for 3 minutes on High Pressure.

Step 10

When done do a QUICK RELEASE and remove vegetables with a slotted spoon.

Step 11

Slice the Corned Beef across the grain and serve on a platter with the vegetables. The cooking juices may be spooned over the meat to keep it moist.
