I’ve got a plan for tomorrow.

It’s Saturday. It also happens to be the day after St. Patrick’s Day and many of us will have leftover corned beef in the fridge so…..

I say we sleep in late and make these Leftover Corned Beef Breakfast Sandwiches. Sound good?

English muffin halves topped with sauce, corned beef, an egg, and cheese on a foil lined baking sheet.

They are oh-so simple to make.

Just top a couple of English muffins with a fried egg, some of your leftover corned beef, a good amount of shredded Irish white cheddar cheese and pop them under the broiler for a minute or two until melt-y, toasty, and glorious. Once they come out of the oven, top them off with some Thousand Island dressing and you’ve got a warm, delicious breakfast sandwich that is perfect for a lazy weekend morning.

Especially if you had a pint (or two) the previous night.

Look for Irish white cheddar in your grocery store’s deli or gourmet cheese section. I used this Aged White Cheddar from Kerrygold. It enhances this sandwich with a creamy, nutty, salty bite that is entirely intoxicating. I’m certain you’ll happily consume any that is left after you make your sandwiches.

If you’re lucky enough to have corned beef leftovers this weekend, I hope you’ll give these delicious breakfast sandwiches a try!
