How to Make Reuben Casserole Step by Step
Step 1: Prepare the Ingredients
Gather all the ingredients needed for the casserole. You will need rye bread cubes, corned beef, sauerkraut, Swiss cheese, Thousand Island dressing, butter, and a few seasonings. Preheat the oven to 350°F (175°C) and lightly grease a baking dish.
Step 2: Layer the Bread and Meat
Spread half of the rye bread cubes evenly in the baking dish. Add chopped corned beef over the bread layer, making sure it is evenly distributed for balanced flavor in every bite.
Step 3: Add Sauerkraut and Dressing
Drain the sauerkraut well to avoid excess moisture. Spread it over the meat layer, then drizzle Thousand Island dressing across the casserole. This creates the classic tangy and creamy Reuben flavor.
Step 4: Top with Cheese and Remaining Bread
Sprinkle shredded Swiss cheese generously over the casserole. Add the remaining rye bread cubes on top and lightly brush melted butter over the bread to help it become golden and crispy during baking.
Step 5: Bake and Serve
Place the casserole in the oven and bake for 30–35 minutes until the cheese is melted and bubbly and the bread topping is crisp. Let it cool for a few minutes before serving warm. Enjoy this hearty comfort meal with pickles or a fresh salad.

Tips for the Best Reuben Casserole
Use Quality Corned Beef
Fresh deli-style corned beef gives the casserole a richer and more authentic flavor compared to packaged lunch meat.
Do Not Skip Draining the Sauerkraut
Excess moisture can make the casserole watery. Thorough draining ensures the perfect texture.
Toast the Bread for Better Texture
Toasted rye bread cubes absorb flavor without becoming mushy. This creates a satisfying contrast between creamy filling and crispy topping.
Layer Evenly
Even layering guarantees balanced bites filled with cheese, meat, dressing, and sauerkraut in every serving.
