Ingredients
For the Casserole:
-
1 (32 oz) jar sauerkraut, drained and rinsed
-
1.5 lbs deli-style corned beef, roughly chopped or sliced into strips
-
12 slices Swiss cheese
-
1/2 cup Thousand Island dressing
-
1/3 cup Russian or Thousand Island dressing (for topping)
For the Rye Crumb Topping:
-
4 slices rye bread, torn into pieces (or about 2 cups rye breadcrumbs)
-
2 tbsp unsalted butter, melted
-
1 tbsp fresh parsley, chopped (optional)
-
1 tsp caraway seeds (optional, but highly recommended for authentic flavor)
For Serving (Optional):
-
Additional Thousand Island or Russian dressing
-
Fresh parsley for garnish
-
Marbled rye bread slices, toasted
Equipment
-
9×13 inch baking dish
-
Mixing bowls
-
Colander (for rinsing sauerkraut)
-
Food processor or blender (for making breadcrumbs, optional)
Instructions
Step 1: Prep & Preheat
Preheat your oven to 375°F (190°C). Grease the 9×13 inch baking dish lightly with butter or non-stick spray. Drain the sauerkraut in a colander and rinse it thoroughly under cold water. Squeeze it firmly with your hands to remove as much excess liquid as possible. This prevents the casserole from becoming watery. Set aside.
Step 2: Create the Rye Topping
If using bread slices, place the torn rye bread into a food processor and pulse until coarse crumbs form. In a medium bowl, combine the rye breadcrumbs, melted butter, optional parsley, and caraway seeds. Toss until the breadcrumbs are evenly coated. Set aside.
Step 3: Assemble the Layers
This is where the magic happens. Layer the ingredients in the prepared baking dish in the following order, spreading each layer evenly:
-
The Base: Spread the drained, rinsed sauerkraut evenly across the bottom of the dish.
-
The Beef: Scatter the chopped corned beef over the sauerkraut layer.
-
The Dressing: Drizzle the 1/2 cup of Thousand Island dressing evenly over the corned beef.
-
The Cheese: Layer the Swiss cheese slices neatly to cover the entire surface, overlapping slightly if needed.
Step 4: Add the Finishing Touches
Spoon the remaining 1/3 cup of dressing in small dollops over the cheese layer. Finally, sprinkle the prepared buttery rye breadcrumb mixture evenly over the top.
Step 5: Bake
Place the casserole dish on the center rack of the preheated oven. Bake, uncovered, for 40-45 minutes. The casserole is done when the cheese is fully melted and bubbling around the edges, and the rye topping is deep golden brown and crisp.
Step 6: Rest and Serve
Remove the casserole from the oven and let it rest for 8-10 minutes before serving. This crucial step allows the layers to set slightly, making it easier to cut and serve neat portions. Garnish with fresh parsley if desired. Serve directly from the dish with extra dressing on the side and toasted rye bread for the ultimate experience.
Chef’s Notes & Variations
-
Make Ahead: Assemble the casserole completely (through step 4) up to a day in advance. Cover tightly with plastic wrap and refrigerate. When ready to bake, let it sit at room temperature for 20-30 minutes while the oven preheats, then bake as directed, adding 5-10 minutes to the bake time if needed.
-
Corned Beef Shortcut: For an even quicker version, you can use 1-1.5 lbs of chopped pastrami.
-
Vegetarian Twist: Omit the corned beef and substitute with 2 cups of sliced mushrooms sautéed with a pinch of smoked paprika, or use a plant-based deli “meat” alternative.
-
Dressing Note: Russian dressing (which contains more horseradish/pickle relish) can be used interchangeably with Thousand Island for a slightly zestier flavor profile.
-
Top Tip: For a super-crisp topping, you can broil the casserole for the final 1-2 minutes of cooking. Watch it closely to prevent burning!
