Do I have to use beer for instant pot corned beef? While the alcohol does cook out of the beer, 1 1/2 cups of beef broth mixed with 1 tablespoon of cider vinegar makes a delicious substitute.

Slow cooker: Corned beef cooks well in a slow cooker or Instant Pot. In a slow cooker, add the brisket, enough water to cover it, and the spices from the spice packet or your own spices.
