    Keto Reuben Casserole - 3 Net Carbs

    Jump to Recipe Pin for Later

    Keto Reuben Casserole is all the classic flavors we love, layered into one 30 minutes meal.  Corned beef, sauerkraut, special sauce, and Swiss cheese layer up to make a hearty and family friendly dinner.

    Who else grew up on reuben sandwiches?  My mom made some that were absolutely delicious!  Corned beef, Swiss cheese, and sauerkraut sandwiched between 2 pieces of garlic butter soaked rye bread.  They were heaven...even without the sauce.

    This casserole is so close in flavor, I don't even miss the rye bread.  It is so easy to make...just layer everything up in the casserole dish and bake in the oven.

    Our layers start with 1 pound of deli sliced corned beef, followed by a layer of sauerkraut, a layer of special sauce, and finally a layer of Swiss cheese.

    steps to layering reuben casserole

    The special sauce is amazing and gives the reuben casserole all of the flavor.  The ingredients are mayo, sugar free ketchup, minced onion, keto friendly sweetener, dill pickle relish, and white vinegar.

    The first time I made this we used half of the sauce, but this deserved extra sauce, so we doubled it!

    Even my picky husband loves Reubens and this casserole.

    Can I use canned corned beef or homemade corned beef?

    Yes, you can definitely use canned corned beef or homemade corned beef.  Just be aware of the carb counts on both of those.  The deli corned beef I used had zero carbs.

    Serving suggestions

    This is a rich casserole so I would suggest serving this with a fresh green salad or a sautéed green vegetable such as zucchini or Brussels sprouts.

      My husband and father LOVED this! We had a leftover corned beef brisket so I used it. I’m not a Ruben fan so I didn’t try it, but they gave it 5-stars. The only change I made was that I didn’t use a 9x13, the dish I used was a bit smaller.

      This is delicious, but there was a lot of liquid in the pan when it wad done cooking. I did drain the sauerkraut!

      The sauce is delicious. It is the same recipe that I use to make thousand island dressing except I leave out the onion and add a boiled egg. It was all great.

      this is a winner! The sauce puts over the top. I added some caraway seeds to mimic a little rye bread flavor.

        I considered doing the same, but couldn’t find caraway in my spice cabinet and didn’t want to go to the store. I will make sure I have them next time I make this.

      I’ve been this numerous times and absolutely love it!!! Made it and had my very picky Momma out for dinner and she asked for seconds! A huge hit!!! Now I have a question: my youngest daughter is about to have a major surgery and I would love to make this and freeze one for them to eat while she recovers. Do I bake it then freeze it, do I assemble it and freeze it before freezing???? HELP!!!!!!

        I would think that you would make it, bake it and then freeze it. They can then reheat in oven or Microwave. Hope all went/goes well with your daughters surgery.

      Delicious. I make a corned beef brisket, not deli meat, and do this. It’s so good.

      I also put a teaspoon or so (I never measure ?) of caraway seed in with the corned beef... completes the flavor profile for me!!!!

      Turned out delicious we all loved it! Will definitely go into rotation in our weekly keto meals. Ps I added caraway seeds into the casserole. I added them on top of the sauerkraut and I believe it added a nice touch to it!

      This tasted just like a reuben, it was so easy to make & I enjoyed it very much. I didn’t miss the rye bread, at all. I’ll make again.
