Flavorful and filling, this Reuben Raclette Casserole takes the components of a Reuben sandwich and rearranges them into a slightly tangy, flavorful concoction that can be dressed up by serving it in individual ramekins or coquettes or made for easy buffet or family style serving in a casserole dish.
I’ve been obsessed with figuring this out since I had a version of it on a cruise ship last year. Of course, that version came with potatoes and regular rye bread, so I needed to keto-fy it. That version wasn’t really a casserole either or a main course. So, some invention was required. This dish assumes you have cooked corned beef. You can either make it yourself or buy it from the deli. I’d never made corned beef before but found that it was super easy, though I freely confess to having bought it already brined and with a seasoning pack included rather than making that part up myself. So all I had to do was vacuum seal it and toss it in the sous vide container to cook.
Pair it with my Keto Irish Boxty or my Reuben Stuffed Mushrooms and you’ve got a party on your hands. Check out my Shamrock Dinner Party for some other menu suggestions.

Equipment

- Strainer for draining and rinsing the sauerkraut

- Large Mixing Bowl
- Non-stick Cooking Spray
- Whisk for beating the eggs and other liquids
- Rubber Scraper Or Other Large Spoon
Notes
- Bread Options
- For the bread, if you are not trying to keep this keto / low carb, you can use rye bread. The number of slices–10–is based on the relatively thin slices that my seeded keto bread comes in. This should be about 4 cups of bread cubes.
- If you want it to be keto, but don’t have access to store-bought keto bread, I would suggest using this Keto Cheesy Skillet Bread recipe from All Day I Dream About Food. Just make it, cube it, and then dry out the cubes in the oven like you would with the store-bought bread. However, it will take a bit longer. Just keep an eye on it so that you don’t burn your hard work.
- Corned Beef
- I bought corned beef that was already brined and came with a spice packet. I cooked it sous vide and it came out perfectly. You can find my instructions here. After the corned beef is done cooking, let it cool a bit on the counter, remove it from the bag of liquid that was produced by the cooking process, stick it in another zip top bag and stash it in the freezer for 30 minutes before slicing and dicing. This will help it to firm up a bit, making it easier to cut up.
- You could also just buy corned beef from the deli.
- You only need 1 pound of the corned beef for this recipe, so I recommend either using another ½ pound to make my Reuben Stuffed Mushrooms or saving it to slice for sandwiches later in the week.
- Cheese
- I used shredded gruyere because I’m not personally a fan of regular Swiss cheese. However, if you like it, go for it.
- I topped this with Raclette cheese. You may have to look around to find this in your grocery store. If you can’t find this, you could use slices of gruyere or Swiss cheese instead.
- Stock
- I used my Homemade Chicken+ Broth, because that’s what was handy. However, you could use beef stock if you prefer.)
- Sugar-free Thousand Island Dressing
- If you are not trying to keep this keto / low carb, you can use regular Thousand Island Dressing.
- Alternative Serving Suggestion
- Rather than making this as one big casserole, you could portion it into individual coquettes and top each one with a slice of Raclette for a more fine dining-esque presentation.
