Ingredients & What You’ll Need

For the Casserole:

• 1 pound Deli Corn Beef, chopped
• 1 Cup Sauerkraut, drained
• 2 Cups Shredded Swiss cheese

For the Dressing:

• ½ Cup Mayonnaise
• 4 Tablespoons Ketchup (sugar-free for keto)
• 2 Tablespoons Minced white onion
• 2 teaspoon sugar free granulated sweetener
• 2 teaspoon Dill Pickle Relish
• 2 teaspoon White vinegar

How to Make Keto Reuben Casserole

This recipe is simple, utilizing layering to build maximum flavor in your casserole dish.

Making the Dressing

First, pre-heat your oven to 400°F (200°C). In a small mixing bowl, you should combine the mayonnaise, ketchup, minced onion, granulated sweetener, dill pickle relish, and white vinegar. Stir this mixture thoroughly until the ingredients are well blended. Set the dressing aside while you prepare the casserole.

Assembling and Baking the Keto Reuben Casserole

Spray the inside of a 9×13 casserole dish with cooking spray. Spread the chopped corned beef evenly in the bottom of the dish. Next, spread the drained sauerkraut evenly on top of the corned beef. Spread the dressing mixture over the sauerkraut layer. Finally, top the entire casserole with the shredded Swiss cheese. Bake the dish in the pre-heated oven for 20 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Serve the casserole immediately.

Tips for a Perfect Reuben Casserole

• Draining Sauerkraut: Always press as much liquid as possible out of the sauerkraut before adding it to the dish. Excess moisture can make the casserole watery.
• Cheese Choice: While Swiss cheese is traditional, you can substitute it with Gruyère for a richer flavor.
• Make it Faster: For even quicker assembly, you can use a store-bought keto-friendly Thousand Island or Russian dressing instead of making the dressing from scratch. Just ensure it has zero or low sugar content.
• Serving Suggestions: This dish is very rich on its own. Serve it alongside a crisp, simple green salad or some low-carb steamed green beans to balance the richness.

This Keto Reuben Casserole is an incredible way to enjoy classic comfort food while sticking to a low-carb lifestyle. It is a hearty, flavorful dish that is guaranteed to be a hit with both keto and non-keto eaters.
