Keto Reuben Casserole

Low Carb / Keto / Gluten Free

This recipe holds a special place in my heart. The moment I realized that I needed to make a blog was when I was consuming a delicious and bunless corned beef sandwich. When I first took a bite, I was immediately transported back to that St. Paddy's Day. This Keto Reuben Casserole is comforting and filling - perfect for this time of year.

You know, I wasn't always a corned beef fan. In fact, growing up, I mostly only ate chicken and an occasional beef burger. Oh, and bacon, of course. Oh how the times have changed. I am very much a meat-eater now, though I do still enjoy veggies.  This casserole has sauerkraut mixed in (if you're trying to eat a veggie at every meal like me) but it would be perfect alongside a scoop of mashed cauliflower.

Originally, this recipe was made as a dip. In fact, I took it to the first official Steeler's game party of the season with some celery and rye bread for the non-keto-ers.  It wasn't until one of my friends (also doing a low carb diet) started eating it alone that I thought of turning it into a casserole.  It was a hit as a dip, but I enjoyed the small remainder for lunch the next day. Perfect.

The caraway seeds are mostly optional, but they add that small bite that traditional rye bread would add. I quite enjoy them!

As far as corned beef goes, I simply went to my deli and got it from there. I didn't have enough time to slow cook a corned beef. Canned was an option, but I think the deli worked out extremely well (check the carbs on the brand, I found one at zero carbs, but there were a few with a couple).

Like I mentioned earlier, this Keto Reuben Casserole can be served as is or as a dip. It has been tested both ways, and there were no disappointments!

Keto Reuben Dip - Perfect for St. Paddy's Day!

Reuben Casserole


  • ½ pound corned beef diced
  • 1¾ cup sauerkraut, drained (I use canned)
  • 2 cups swiss cheese shredded
  • ½ cup mayonnaise
  • 8 oz cream cheese
  • ½ cup low-sugar ketchup
  • 2 tablespoons pickle brine
  • ½ teaspoon caraway seeds


  1. Preheat oven to 350 degrees F.
  2. In a sauce pan, melt the cream cheese, mayonnaise and ketchup over low heat. While that is melting, slice and dice your corned beef into half inch chunks.
  3. Once the the mixture is melted, add the can of drained sauerkraut, a cup and a half of the swiss cheese and chopped corned beef. Mix until all incorporated and the cheese is melted.
  4. Take the sauce of the heat and mix in the pickle juice if you have it. If not, add a tablespoon of salt, a teaspoon of vinegar and a pinch of garlic salt.
  5. Pour into a greased dish (I used a 9 inch pie pan) and top with remaining swiss cheese. Garnish by sprinkling caraway seeds on.
  6. Pop in the oven for about 20 minutes until the mixture is bubbling and the cheese on top is melted.
  7. Enjoy!

    Holy crippity-crap this just went in the oven and it smells amazing! Thank you for sharing this recipe!

    thank you so much for creating this dish!!! I’ve been low carbing for awhile but it’s been difficult to get my husband on board. One bite of this and he declared it the best thing he’s ever eaten and that the world should know about this. Two thumbs up we will be making this a regular in our meal planning rotation! Thank you!

      What a stunning review! Love that! So glad you and your family enjoyed it 🙂

  4. AnitaB on January 4, 2015 at 4:50 pm

    Oh wow, I am so going to make this. I have been wondering about recipes with sauerkraut as I grew up eating it in my German family. This is going to be good!

  5. Nicole on October 7, 2014 at 11:45 pm

    Making this tonight! Thank you, I have missed my reuben!

  6. Donna on October 2, 2014 at 6:21 pm

    Any ideas if it freezes well? I’m about to find out. I am making a couple casseroles and think I will freeze this one
    I’ll let you know if it doesn’t.

    • Dominic on October 3, 2014 at 1:48 am


      I haven’t tried freezing but assume it would. Do let us know!


  7. Lin on September 25, 2014 at 3:12 pm

    Hahaha! Never mind! I just saw your answer. But can you please update the recipe to reflect that? Again, thanks!

  8. Lin on September 25, 2014 at 3:11 pm

    A whole tablespoon of salt for the pickle juice substitute? That sounds like a lot of salt, especially with the saurkraut and corned beef. Thanks, Dominic! 🙂

  9. Lisa Rudlaff on August 8, 2014 at 12:40 am

    What size can of sauerkraut? I’m so excited about making this, but I want to make sure on the size of the sauerkraut can before I try this recipe. Thanks!

    • Dominic on August 9, 2014 at 3:17 pm

      Mine was 14 oz! You can actually use as much as you’d like as it is the breadth of the dish!

    […] me tell you something about the nutrition value for keto reuben casserole (I know you are eager to read how many calories, fats and stuff it has). For a 1/8 of a meal you […]

    In your directions, you indicate that if you don’t have pickle juice, to add a tablespoon of salt. Is this right? I can’t imagine adding more than a teaspoon, and even that would be a lot, especially with the saltiness of the corned beef.

    • Dominic Geracia on December 17, 2013 at 2:45 am


      That should say teaspoon, sorry!


  12. Spatz on November 15, 2013 at 8:08 pm

    Oh I just love your website! And I have been missing my reubens for soooo long being on the carb nite diet as well, I am making this tonight!

    • Dominic Geracia on November 15, 2013 at 8:51 pm


      Thank you so much! I hope you enjoy it as much as I loved making it 🙂

        Some feedback,

        I made the reuben cass for dinner like I mentioned, and while it tasted very good, and very much like a reuben, we found it to be more like a “Reuben Dip” than a “Reuben Casserole.”

        Still super happy I found it, and we just ate it with celery sticks and very much enjoyed it. I’ll make it next game night and I’m sure it’ll be a big hit!

        Thanks again for sharing your recipes! It was super easy to follow.

    Always happy to have you over for the games because you bring such tasty dishes. Andrew is always surprised to like what you bring because he knows your diet preferences.

    I think you’re starting to change his mind that keto and gluten-free doesn’t mean food can’t still be tasty.

    • Dominic Geracia on November 15, 2013 at 3:11 am


      That’s the idea here! I think most people see the diet as simply a meat fest, and it is far from that! Sure, you can enjoy meat, but there are so many other options as well. I always appreciate the game invites and the awesome company!


  14. Betsy on November 1, 2013 at 3:27 am

    This is such a great recipe. Thanks so, so much!

    • Dominic Geracia on November 3, 2013 at 2:25 am


      You’re very welcome! Glad you enjoyed this as much as I do!


  15. Heather on October 9, 2013 at 5:45 pm

    I could have eaten the whole pan myself! Its so delicious!! I made this to eat on for the whole week and I’m down to 1 piece (its only Wednesday!!) So delicious. Will be sharing with my family!

    • Dominic Geracia on October 10, 2013 at 3:27 am


      So glad you enjoyed it! It is one of my absolutely favorites.



  16. Amy on September 29, 2013 at 3:16 pm

    Thanks, Dominic, I’m totally making this today!

  17. Amy on September 29, 2013 at 2:19 pm

    Looks awesome! This may be a dumb question, but can you clarify how much 1 packet of cream cheese is? Is that a small packet or an 8 oz package? Thanks!

    • Dominic Geracia on September 29, 2013 at 2:26 pm


      Not dumb at all, I should have specified! I was talking about a 1* 8oz package. I’ve updated the recipe to make it easier for people in the future!



  18. Amanda on September 11, 2013 at 4:12 pm

    This sounds so yummy! I really miss ordering a reuben at the pub so this is just great!

    • Dominic Geracia on September 11, 2013 at 5:04 pm


      I hope you like the recipe. I’m not even kidding when I said that this recipe holds a special place in my heart. It’s fantastic. I think it’s going to end up becoming one of my weekly meals!
