Preheat Oven: Begin by preheating your oven to 350°F (175°C). Lightly grease a baking dish to ensure easy removal and prevent sticking.

Prepare Ingredients: Cube the rye bread slices, shred or thinly slice the corned beef, and drain and rinse the sauerkraut. Having everything ready will make the layering process smooth and efficient.

Layer Ingredients: Start by layering half of the cubed rye bread in the bottom of the greased baking dish. Next, add half of the corned beef, followed by half of the sauerkraut. Sprinkle half of the grated Swiss cheese over the sauerkraut layer, ensuring even distribution.

Add Dressing: Drizzle half of the Thousand Island dressing evenly over the cheese layer, adding a creamy and tangy element to the dish.

Repeat Layers: Repeat the layering process with the remaining ingredients: rye bread, corned beef, sauerkraut, and Swiss cheese. Building these layers creates a harmonious blend of flavors and textures.

Finish with Dressing: Drizzle the remaining Thousand Island dressing evenly over the top layer of cheese, providing a luscious finishing touch.

Bake: Cover the baking dish with aluminum foil to trap the heat and moisture, then place it in the preheated oven. Bake for approximately 25-30 minutes, or until the cheese is melted and bubbly, and the casserole is heated through.

Serve: Once baked to golden perfection, remove the foil and allow the Reuben Bake to cool slightly before serving. Cut into squares and serve hot, savoring each mouthwatering bite.
