Take out the corned beef and wrap in tinfoil and set aside.
Place potatoes, cabbage wedges and carrots into the pot.
Take the corned beef out of the tin foil and slice it against the grain. The beef should be fork-tender and cut easily.
Serve vegetables immediately with the corned beef.
Store leftovers in an airtight container in the fridge.
*You can add any other vegetables to this recipe. For instance, I have seen multiple recipes that add onions into the mix. Just throw them in the instant pot with your other veggies!
