How to Make Easy Keto Reuben Casserole
Step 1: Preheat the Oven
Preheat your oven to 400 degrees Fahrenheit. This ensures that your casserole cooks evenly right from the start.
Step 2: Prepare the Sauerkraut
Drain liquid from sauerkraut using a mesh strainer. If you don’t have one, a cheesecloth or even paper towels will work in a pinch. This step is crucial for avoiding excess moisture.

Step 5: Add Sauce and Cheese
Drizzle half of the Russian dressing over the layers and sprinkle with one-third of the Swiss cheese. Repeat these layers with remaining ingredients (meat, sauerkraut, sauce, pickles, and cheese).
Step 6: Bake the Casserole
Cover your casserole with aluminum foil and bake for 10-15 minutes or until the cheese is bubbling.
Step 7: Broil for Finish
Remove foil and broil for an additional 2-3 minutes until golden brown on top.
