How to Make Easy Keto Reuben Casserole
Step 1: Preheat the Oven
Preheat your oven to 400 degrees Fahrenheit. This step is essential for ensuring that your casserole cooks evenly.
Step 2: Prepare the Sauerkraut
Drain liquid from the sauerkraut using a mesh strainer. You can also use cheesecloth or paper towels if needed. It’s important to remove excess moisture to keep your casserole from becoming watery.

Grease your casserole dish with nonstick cooking spray or butter. This will prevent sticking and make serving easier.

Start by layering half of the corned beef in the bottom of your dish. Next, top with sauerkraut and diced pickles.
Step 5: Add Sauce and Cheese
Drizzle half of the Russian dressing over the layers and sprinkle one-third of the Swiss cheese on top. Repeat these layers with the remaining ingredients (corned beef, sauerkraut, pickles, sauce, and cheese).
Step 6: Bake
Cover with aluminum foil and bake in the preheated oven for about 10-15 minutes, or until the cheese is bubbling.
Step 7: Broil for Extra Crispiness
Remove the foil and broil for an additional 2-3 minutes until golden brown on top. Once done, serve hot!
