Seeking comfort food? This cheesy Reuben Noodle Casserole recipe featuring corned beef, egg noodles, Swiss cheese and more is a delight.

Once the meal of corned beef and cabbage has been consumed, what’s next? Pack up the leftovers and then, have it again a few times until it’s gone? Well, you could. But, oh, there are so many great ways to use up leftovers from that ubiquitous American dinner often consumed around St. Patrick’s Day.
Corned Beef Skillet for One is a personal favorite. So is Irish Benedict. Or maybe you just want Corned Beef Hash? If you are looking for something a bit more outside the box though, I have a recipe for you. Seriously, this is the leftover recipe you didn’t know you needed.


Reuben Noodle Casserole takes the best flavors of a Reuben sandwich and transforms them into a cheesy, comforting pasta bake. Fine egg noodles are mixed with cubed leftover corned beef and a creamy Swiss cheese sauce and spread into a casserole. Then it’s topped with tangy sauerkraut, more cheese and toasted rye bread crumbs. Finish it off with bits of butter and bake to perfection.
It’s divine.
A note on sauerkraut before we go any further. Since I was a child, Silverfloss has been the go-to in our house. I generally prefer the refrigerated bag of it to the canned, but both are good. However, here in Maine, Morse’s Sauerkraut is even better. It’s locally made and locally available (I buy it at our local Hannaford). So if you have the option for something even fresher, take it.

Although Reuben sandwiches often have Thousand Island dressing, this skips it. The dish is rich and filling on its own. But if you are missing the added flavor, serve a dollop on the side and dip forkfuls in.
Ready to get cooking? To make this, you will need leftover corned beef for starters. I tuck some aside when serving for later, typically. Then you’ll have to craft the cheese sauce. Mix, layer and bake and you’ve made it.

Although this Reuben Noodle Casserole recipe takes about an hour to make, it’s pretty easy overall and the leftovers reheat well. Scoop it onto a microwave-safe plate and cook for about 90 seconds.
