Before you start

Before beginning, ensure all ingredients are measured and ready. Drain the sauerkraut thoroughly using a fine-mesh sieve to remove excess liquid, as this is crucial for maintaining the right texture. Slice the corned beef into manageable, bite-sized pieces if the slices are very large.

Preheat the oven fully to 375 degrees Fahrenheit to ensure the baking time is accurate. Arrange the baking dish on a stable surface for easy assembly, and keep all ingredients within reach to streamline the process.

Ingredients at a glance (5)
  • 8 slices rye bread, cubed
  • 1 lb corned beef, thinly sliced
  • 1 1/2 cups sauerkraut, drained
  • 1 1/2 cups Swiss cheese, shredded
  • 1 cup Thousand Island dressing

Instructions

Base Preparation

  1. Prepare the Base
    Preheat the oven to 375 degrees Fahrenheit. Grease a 9x13 inch baking dish lightly. Cut the rye bread into uniform cubes and spread them evenly across the bottom of the prepared baking dish to form a sturdy foundation.
    Look for bread is cut into even cubes
    Tip ensure the bread cubes are distributed evenly so every bite has texture.

The rye bread should be cut into uniform, bite-sized cubes that cover the bottom of the dish in a single, even layer. There should be no large gaps, as this forms the structural foundation of the entire casserole. The dish itself should be lightly greased to prevent sticking, ensuring that the finished bake can be removed easily from the pan once it has completed its time in the oven.

Layering Assembly

  1. Assemble the Layers
    Layer the thinly sliced corned beef over the rye bread. Spread the drained sauerkraut evenly over the meat, then drizzle the Thousand Island dressing across the top. Finally, cover the entire surface with the shredded Swiss cheese to ensure a bubbly, golden crust.
    Look for cheese covers the entire top layer
    Tip draining the sauerkraut well prevents a soggy casserole.

The layers should be distinct but visually integrated. The corned beef should be spread evenly over the bread, followed by the sauerkraut. The Thousand Island dressing should be drizzled in a way that covers the surface area to ensure moisture reaches all layers.

Finally, the Swiss cheese must be distributed uniformly, covering the entire top surface to guarantee a consistent, bubbly, and golden-brown crust across the entire casserole during the baking process.

Final Baking

  1. Bake and Serve
    Place the dish in the preheated oven and bake for 25 minutes until the cheese is melted and bubbling. The internal temperature of the corned beef should reach 145 degrees Fahrenheit (63 degrees Celsius). Remove from the oven and let it rest for 5 minutes before slicing and serving.
    Look for cheese is golden brown and bubbling
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip resting allows the layers to set properly for easier serving.

The casserole is ready when the cheese is deeply golden and shows vigorous bubbling around the edges of the dish. The aroma should be savory and slightly tangy, indicating that the flavors have melded perfectly.

The internal temperature must be confirmed at 145 degrees Fahrenheit (63 degrees Celsius). After the required 5-minute rest, the bake should look firm enough to hold its shape when lifted with a spatula, with the bread base now tender and flavorful.

Common mistakes

A common mistake is using too much liquid from the sauerkraut, which can lead to a soggy base. Always drain it well. Another error is overcrowding the baking dish, which prevents the cheese from browning evenly. Ensure the dish is the correct size. Finally, failing to let the dish rest after baking will make it difficult to serve, as the layers may slide apart. Patience during the resting phase is essential for a beautiful final presentation.

How to tell it’s done

The Reuben bake is done when the cheese on top is fully melted, bubbling, and has developed a light golden-brown color. The edges should appear slightly crisp. The internal temperature of the corned beef layer must reach at least 145 degrees Fahrenheit (63 degrees Celsius) to ensure quality.

Allow the dish to rest for 5 minutes after removing it from the oven, as this helps the structure set, making it much easier to slice into clean portions for serving.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
