When I have a sandwich craving, it’s usually for a Corned Beef Reuben Sandwich.  They’re the perfect blend of melty, tangy, salty and sweet that no other sandwich can compare to. We love a deli in our area for their super messy reuben sandwich but in a pinch, I like to make them at home.

The Reuben Sandwich is super simple to make BUT when I want to make something extra comforting I throw everything into a casserole dish and make this easy Reuben Casserole. It’s fast to whip up and it’s always a huge hit with the family.

Reuben Casserole

If you’re not familiar with the Reuben Sandwich, it’s basically a grilled sandwich made of corned beef, swiss cheese, sauerkraut and dressing. It’s associated with Jewish delicatessens but it’s not, actually, kosher because it contains both meat and cheese.

You can also make a reuben sandwich with pastrami but we’re big fans of corned beef, plus it’s great for using up leftovers from St. Patrick’s Day.

How To Make It

This Reuben Casserole is inspired by the sandwich but is layered in a casserole dish before being baked into a gooey, melty, comfort dinner.

Traditionally, the sandwich is made with Russian Dressing but I like to use my homemade Thousand Island dressing. It has a bit more flavor and the family loves it.

Pro Tips

  • We like to use leftover Corned Beef for this recipe but you can use deli corned beef or even pastrami to make things easier.
  • Be sure to DRAIN your sauerkraut before assembling the casserole so you don’t end up with a soggy meal. I like to put it in a strainer and give it a good rinse, then press down with a paper towel to squeeze out the excess.
  • Shredded swiss cheese will work best because it melts down into the crevices of the other ingredients but you could use sliced deli swiss, too.
  • Thousand Island dressing and Russian Dressing are very similar so they’re basically interchangeable in this recipe.

What To Serve With It

Because this casserole is a one pot dinner, you don’t really need a side BUT we love to serve it with this easy Loaded Wedge Salad to round it out with something fresh. 

You could also serve it alongside a big pile of green beans or make it a completely Irish feast with these easy Colcannon Potatoes. They’re so, sooo amazing!

If you’re looking for even more easy Irish recipes, we love this recipe for Bangers and Mash…although it’s more British than Irish. Or you can try my favorite mini Irish Soda Bread muffins.

We’re also loving these personal sized Reuben Pizzas...they’re melty and amazing AND just like an open faced reuben sandwich. Then, follow it up with a Nutty Irishman. My FAVORITE!
