This Reuben casserole has the flavors of the classic sandwich, baked into a low carb casserole! With corned beef, sauerkraut, plenty of cheese, and creamy Russian or Thousand Island dressing, it only takes 30 minutes to make this recipe, with only 5 minutes prep!
What Makes This Recipe So Good
- There are only FOUR INGREDIENTS in this casserole! Corned beef, sauerkraut, Russian dressing, and Swiss cheese. Everything you love about a classic Reuben (minus the rye bread, of course) all baked in to a gooey, savory casserole.
- It’s so, so, so easy – wayyyy easier than putting together a bunch of sandwiches. Just layer the corned beef, the sauerkraut, and the dressing, and bake it a little before adding the cheese and putting it back in the oven.
- There’s no bread or anything in this recipe because it’s designed to be naturally low carb. If you’re keto, you’ll just need a keto-friendly Russian dressing, which you can make yourself super easily! Use my Russian dressing recipe from my Reuben tacos, and make sure your ketchup is keto.

Key Ingredients
Corned Beef – Leftover corned beef would work really well here, but you can also go the easy route and use deli counter corned beef. Whether you slice the corned beef into strips or chop it up is entirely up to you.
Sauerkraut – It’s really important that you not only drain your sauerkraut but you dry it, too. That way you don’t end up with pool of sauerkraut juice in the bottom of your casserole. A quick dab or two with a paper towel should do the trick.
Chef’s Tips
- There may be some liquid in the bottom of the dish after baking the casserole. That’s totally normal with these ingredients, especially since there’s no bread or anything to soak up the excess. The liquid’ll drain off when you lift the casserole out of the dish, and won’t affect the taste or texture at all.
- If you’re not low carb or keto, you can crumble up or chop some rye bread to spread on top of the casserole when you add the Swiss cheese. It toasts up really well and will give the dish a little crunch.
- Make sure to spray the aluminum foil with cooking spray before you cover the baking dish with it, that way it doesn’t stick to the casserole.

- Russian Dressing: If you’re low carb, look for the brand of Russian dressing that has the fewest carbs.
- Cheese: Use a block of Swiss cheese that you shred yourself, to avoid any unnecessary fillers and carbs from pre-packaged, pre-shredded cheese. Fresh cheese also melts better!
- Make it Keto: Make your own Russian dressing at home using my recipe, but make sure you use a keto ketchup. The nutrition information for this Reuben casserole was calculated using my Russian dressing made with keto ketchup.
