This Easy Keto Reuben Casserole Recipe Will Make Your Stomach Smile (2024)

Yep, the image above is correct. Nope, that’s not a typo! Only 3 grams net carbs per serving in this delicious keto reuben casserole.

And we’re not talking about some dinky “diet” serving. We’re talking 1/8th of that big ol’ pan. No need for seconds here. I’m a grown man and I was full from one serving (with no side other than those two pieces of pickled asparagus).

Oh, and did I mention this casserole tastes almost exactly like a real reuben sandwich, minus the carbs.

Sure, you’re skipping the bread but you get all the flavor of the rye bread from the caraway seeds. And don’t forget about the homemade Thousand Island dressing. We’ve got a couple of tricks to make it taste as good (or better) than the real thing.

Sure, it may look like a lot but you’ll probably have most of these ingredients in your kitchen already. In fact, you may only need to run to the store for the corned beef, sauerkraut, Swiss cheese, and caraway seeds.

For the corned beef, it’s best to use a good quality beef since this is the heart of the sandwich…ehem…casserole. I opted for Boar’s Head which, while being kind of pricey, is definitely worth it.

The recipe calls for a pound but I suggest you get a little over a pound since you’ll be snacking on it while making the keto reuben casserole.

It is zero carb so no worries.

As you probably know, traditional Thousand Island dressing is pretty much mayo, ketchup, a pickle relish, and some spices.

BUT, ketchup is definitely not keto. In fact, a tablespoon of sugar-loaded ketchup has 5g of carbs (all from sugar) per serving. We need 3 tablespoons so that’s essentially 15 grams of additional carbs in the sauce.

Fortunately, it’s not necessary. We subbed out this La Victoria Medium Red Taco Sauce in place of the ketchup and actually found it tasted better than when we used the ketchup. NOTE: We tried the mild and found we liked the taste of the medium better. Don’t worry, it’s not spicy.

And this La Victoria taco sauce is super low in carbs at only 1 gram per tablespoon.

After you’ve made the sauce, it’s time to start assembling the keto reuben casserole.

The first thing we want to do is thoroughly grease a large casserole dish. You can use whatever lubricant you want to grease the dish, but for that authentic reuben sandwich taste you’ll want to use butter…and plenty of it.

Remember, butter is what they use at your favorite diner!

Begin by spreading half of the chopped corned beef in the casserole dish. Top the corned beef with about 1/3 of the grated Swiss cheese.

Next, we’ll add the sauerkraut, remaining pickles, and remaining caraway seeds…

Now add the remaining corned beef and another 1/3 of the grated Swiss cheese.

Okay, on to the sauce. Grab a measuring cup or ladle and evenly pour the “Thousand Island” sauce over the casserole.

Finally, add the remaining 1/3 of the grated Swiss cheese on top of the sauce.

Cover with foil and bake for around 40 minutes. Take off the foil, set your oven to broil, and cook for a couple more minutes until the cheese is bubbly and browned.

After the cheese browned, remove the keto reuben casserole from the oven and allow it to sit for at least 5 minutes before cutting. This will help the casserole “set up” a bit before serving.

I know I’ve sold the heck out of this keto reuben casserole but it really is worth all the hype.
