Leftover Corned Beef Low-Carb Reuben Bake!
I love St. Patrick’s Day, and every year I try to encourage people to cook corned beef and cabbage, which go on sale for this holiday in the U.S. And whether you make my tried-and-true Slow Cooker Corned Beef or Instant Pot Corned Beef with Creamy Horseradish Sauce, I really hope you’ll cook some corned beef for the holiday. And of course I’ve already recommended Roasted Cabbage with Lemon as the perfect side dish for corned beef.
And if you’re lucky enough to have corned beef leftovers, I hope you’ll make this amazing Leftover Corned Beef Low-Carb Reuben Bake. But even if you don’t make corned beef (or don’t get any leftovers!) you can buy corned beef at the deli and make this low-carb casserole with layers of mashed cauliflower, cabbage, corned beef, Swiss cheese, and Thousand Island dressing. If you’re a fan of the Reuben Sandwich, you’ll recognize some of those ingredients and realize how this casserole got its name.
This is a recipe I came up with several years ago after I saw a Reuben Bake from My Recipes (probably on Pinterest!) I realized I could switch out the potatoes for cheesy cauliflower (and use low-sugar Thousand Island dressing) and make this into a delicious low carb dish. It took me a couple of tries to get the recipe and photos how I wanted them, but when Kara and I tested this final version we gobbled it up. And I’m hoping I don’t sound like I’m completely lacking in modesty if I say this is a complete winner for a way to use leftover corned beef; enjoy!
How to Make Leftover Corned Beef Low-Carb Reuben Bake:
(Scroll down for complete printable recipe, including nutritional information.)
- Chop up a head of cauliflower and cook in boiling salted water.
- Drain cauliflower at least 5 minutes, then use an Immersion Blender (affiliate link) or hand beater to puree the cauliflower with the sour cream.
- Stir in grated Swiss cheese and green onions.
- Slice up cabbage, shred corned beef apart and then chop, and measure out the Thousand Island dressing.
- Heat olive oil in frying pan and saute the cabbage (seasoned with salt, pepper, and a little caraway seed.)
- When cabbage is starting to wilt, add corned beef and cook 1-2 minutes more.
- Let cool for a few minutes and then stir in the Thousand Island Dressing.
- I used a deep casserole dish so you could see the layers, but any glass or crockery casserole dish that’s not too small will work.
- Make a layer with half the mashed cauliflower in the bottom of the dish.
- Put the cabbage/corned beef mixture over that and top with grated Swiss Cheese.
- Then make another layer of mashed cauliflower, spreading it around.
- Top with another layer of grated Swiss Cheese.
- Bake at 375F/190C about 45 minutes, or until it’s bubbling hot and the top is starting to brown. Serve hot.
I promise this will be a hit with anyone who likes corned beef, even if they don’t care about low-carb eating.

Low-Carb Diet / Low-Glycemic Diet / Low-Carb Diet Suggestions:
For low-carb diets, it’s important to look for Thousand Island Dressing that doesn’t contain a lot of sugar to make Leftover Corned Beef Low-Carb Reuben Bake. (I used Litehouse Thousand Island Dressing with 3 carbs per tablespoon.) Corned beef isn’t really recommended for the South Beach Diet due to the amount of fat, so this is a once-in-a-while treat for South Beach Dieters but I’d certainly make it for St. Patrick’s Day leftovers if you have some. South Beach would also recommend using light sour cream and reduced-fat Swiss cheese if you can find it.
