3 tablespoons ketchup
1 tablespoon grated onion
1 teaspoon prepared horseradish
½ teaspoon Worcestershire sauce
½ teaspoon yellow mustard
½ teaspoon smoked paprika

4 cups Swiss cheese, shredded

How To Make Reuben Casserole

Step 1: Preheat Your Oven

Start by preheating your oven to 350°F (175°C).

This will ensure that your casserole bakes evenly and gets that delightful golden-brown top.

Step 2: Prepare the Sauce

In a medium bowl, whisk together the mayonnaise, ketchup, grated onion, prepared horseradish, Worcestershire sauce, yellow mustard, smoked paprika, salt, black pepper, and eggs.

This sweet and tangy sauce will tie all the flavors together beautifully.

Step 3: Layer the Ingredients

In a large mixing bowl, combine the shredded corned beef, drained sauerkraut, and half of the shredded Swiss cheese.

Gently fold in the cubed rye bread, ensuring everything is well mixed.

Step 4: Combine Everything

Pour the sauce over the mixture and stir until all the ingredients are evenly coated.

This step is essential to ensure that every bite is full of delicious flavor.

Step 5: Transfer to a Baking Dish

Grease a large casserole dish with cooking spray or a little oil.

Pour the mixture into the dish, spreading it out into an even layer.

Top with the remaining Swiss cheese for that gooey, cheesy goodness!

Step 6: Bake

Cover the casserole dish with aluminum foil and bake for 45 minutes.

After that, remove the foil and bake for another 15 to 20 minutes, or until the cheese is melted and bubbly and the top is lightly browned.

Step 7: Let It Cool

Once baked, let the casserole cool for about 10 minutes before serving.

This will help it set up a bit and make it easier to serve.

Expert Tips

For easier cutting, let the casserole rest for a few minutes after taking it out of the oven.
If you love extra flavor, consider adding some pickles or jalapeños to the mixture for a little kick.
Feel free to use leftover corned beef for this recipe; it will taste even better!
