  • 2-quart baking dish
  • Silicone spatula
  • Aluminum Foil
  • Cooking spray


  • 1 pound deli corned beef cut into strips or chopped
  • 1 16-ounce can sauerkraut or 2 cups, drained very well and dried off
  • 1 cup Russian dressing see Notes
  • 2 cups freshly shredded Swiss cheese


  • Preheat oven to 400° Fahrenheit.
  • Lay corned beef evenly in bottom of 2-quart baking dish, then top evenly with sauerkraut. Pour dressing on top of sauerkraut and spread out evenly.
  • Spray aluminum foil with cooking spray and cover baking dish with sprayed-side down. Place covered baking dish in preheated oven and bake for 20 minutes.
  • After 20 minutes, remove dish from oven. Discard aluminum foil and sprinkle Swiss cheese evenly over top of casserole. Return baking dish to oven and bake, uncovered, for 10 minutes or so, until cheese is melted and bubbly. Remove from oven and serve warm with additional dressing if desired.


  • There may be some liquid in the bottom of the dish after baking. 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.
  • 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.
