Slow Cooker Reuben Casserole
One day while flipping through one of those fancy magazines my local grocery store puts out I spotted the idea of a reuben casserole. Because I was checking out and it was my turn at the register I quickly put the magazine back on the rack and filed away the idea of a new casserole in the back of my mind.
I love a good Rueben sandwich with all of it;s corned beef, sauerkraut and Swiss cheese!
When it came time to make the casserole, I didn’t have a recipe to use for reference so I sort of winged it based what I could recall from the magazine. Of course I decided that this casserole would have to be made in my slow cooker.
So, I pulled out my 3.5 quart casserole Crock-Pot (this recipe can also be cooked in a 6 quart or larger slow cooker). And MAN did it come out TASTY!
I hope you enjoy this recipe as much as my family and I did!

Yayyyyy! Thank you sooooo very much for replying to me! My grocery NEVER has it in the deli or lunch meat section so i went ahead and got the canned kind. You’re awesome for replying so quick, i REALLY curious to try your version of a Ruben casserole!
You’re welcome! Hope you enjoy it! I loved it!
Im cooking it now and the pre-taste test is already yummy! It smells awesome! I was wondering if know if anyone knows if it freezes well. There’s ALOT for just the 2 of us….not complaining about that though! 😁
I think it would freeze fine! Glad you like the recipe! Enjoy!
I do not like peppers of any kind at all! Could you substitute celery???
Hi Teresa, while we have not tested this recipe using celery over peppers I don’t see why it wouldn’t work. If you give it a try come back and let us know how it turned out for you!
