Corned Beef Grilled Cheese

There is no more perfect grilled cheese for St. Patrick’s Day than Corned Beef Grilled Cheese. A stack of salty corned beef, topped with sweet caramelized onions, and gooey melted cheese- Yum! This is perhaps the best way to eat corned beef. Can you disagree?

I didn’t even mention the crispy pumpernickel bread.

What is it about pumpernickel bread that makes such a great hot sandwich?

The onions are cooked in beer and flavored with a little Worcestershire sauce, mustard, and a few caraway seeds.

You can use either leftover corned beef that you’ve cooked yourself, or a deli-sliced corned beef.

It reminds me a little of my all time favorite sandwich – the Reuben.

If you really wanted to go with the Irish theme, you could always add some sautéed cabbage to this Corned Beef Grilled Cheese.

  • 2 medium yellow onion, thinly sliced
  • 1 1/2 tablespoons sugar

  1. Do you add the caraway with the salt and pepper?

    I’m making this tonight, and I don’t have caraway today anyway, but I thought I’d ask for future reference!

    This is fantastic. I love Reuben’s and this is an interesting delicious take on them. The onions definitely make up for the sauerkraut and thousand island dressing.
