how to make a reuben casserole
Layering the ingredients of a reuben sandwich in a baking dish makes for an easy comfort food meal. I love that this reuben casserole recipe is so easy to toss together.
Step 1: Start off by tossing the rye bread cubes with melted butter. Transfer half of the cubes to a 9 x 13 inch casserole dish.
Step 2: Next spread the corned beef on top of the bread cubes. Then add the sauerkraut.
Step 3: In a small bowl, make the homemade thousand island dressing. Combine mayonnaise, ketchup, and sweet pickle relish. Spread the dressing evenly over the sauerkraut.
Step 4: Next sprinkle half of the shredded Swiss cheese evenly over the dressing.
Step 5: Top with the remaining buttered bread cubes. Sprinkle the remainder of the cheese on top of the casserole.
Step 6: Bake until the casserole to hot and the cheese melts.
expert tips
Shred the Swiss cheese either by hand or with a food processor. It will be much fresher tasting than the preshredded variety. It also melts beautifully.
Homemade dressings take only a few ingredients to make and are in well stocked pantries. Whipping up a delicious thousand island dressing takes less than a minute. A store bought dressing of this creamy dressing is also an alternative. Bottle Russian dressing is an alternative.
frequently asked questions
Sauerkraut is typically stored in water, and this excess liquid can make the casserole soggy. Drain the sauerkraut, and squeeze out as much water as you can.
Completely cool the casserole and cover with plastic wrap. Store in the refrigerator for up to 3 days. Alternately, transfer the cooled casserole to an airtight container.
Yes you can! Transfer the casserole to an airtight container. Store in the freezer for up to 1 month. Thaw before heating.

I used Jewish rye bread cubes with melted unsalted butter & baked the bread to make lightly toasted croutons. I had deli corned beef which I cut into long narrow strips and then cut them into 3" pieces. For the homemade 1000 Island dressing, I added at least an extra Tbsp. of dill relish. We liked how light and crispy it was using croutons. Very delicious dinner!!
I especially appreciated all the tips and your explanations of why it's helpful to do so - thanks!

I love to hear that Carroll! This is a recipe I make on repeat in our house. It's such an easy way to make reuben sandwiches.

Delicious! I used deli pastrami instead of corned beef. I don't like Swiss cheese so substituted with a mix of provolone & American cheese. Proportions of meat to other ingredients is perfect. This recipe is a keeper! Thank you for sharing!
Amy Casey
I'm glad to hear that my recipe worked with your substitutions. This one is one of my favorites!
Lisa Govel
