Corned beef and cabbage isn't just for Saint Patrick's Day. Using an Instant Pot makes it so easy to have corned beef weekly or even daily. Hey, I won't judge, I know it's good. Using an instant pot to pressure cook your corned beef is so simple, taking only 90 minutes to cook and it really doesn't require a lot of hands on interaction. In fact, while the corned beef is cooking you will have time to search for a leprechaun and get his pot of gold.
