Corned Beef Grilled Cheese with Guinness Caramelized Onions

I guess you could say this Corned Beef Grilled Cheese with Guinness Caramelized Onions is the sister sammy of the Reuben.

The Reuben sandwich (sammy) has always been my favorite, but this one gives it a lot of competition.  Yes, this still has the tender corned beef, but this time we are loading it in to a grilled cheddar cheese sandwich with Guinness flavored caramelized onions, grainy mustard and Worcestershire sauce. How incredible does that sound!

The only time consuming part of this is simmering the onions in the Guinness 4 times for about 15 minutes each time.  But usually, I can find plenty of other things to be doing in the kitchen while that is going on.  And once you’ve done that part, the rest is easy and well worth it.

Give this a try soon, and you’ll make all your fans happy!
