Ingredients (Serves 8)
Gather these ingredients before getting started:
-
8–10 slices rye bread, cubed (about 4–5 cups)
-
½ cup (1 stick) unsalted butter, melted
-
1 pound (16 oz) corned beef, sliced or chopped into bite-sized pieces
-
1 can (16 oz) sauerkraut, drained and rinsed
-
2 cups shredded Swiss cheese
-
½ cup Thousand Island dressing
-
2 tablespoons chopped fresh parsley (optional, for garnish)
-
2 teaspoons caraway seeds (optional, for added rye flavor)
Ingredient Notes:
-
Rye Bread: The soul of the Reuben. Choose seeded or marble rye for extra depth.
-
Corned Beef: Deli-sliced or leftover roast both work beautifully.
-
Sauerkraut: Rinsing helps reduce excess salt and sourness.
-
Cheese: Swiss is classic, but Gruyère can be used for a nuttier taste.
-
Dressing: Thousand Island ties everything together with sweetness and tang.
Step-by-Step Instructions
Step 1: Preheat the Oven
-
Preheat your oven to 350°F (175°C).
-
Grease or spray a 9×13-inch baking dish with nonstick spray or a bit of butter.
This helps prevent sticking and ensures even baking.
Step 2: Prepare the Bread Base
-
Cube the rye bread into roughly 1-inch chunks.
-
In a large bowl, toss the cubes with melted butter until well coated.
-
Spread half of the buttery bread cubes across the bottom of your prepared baking dish.
This forms a flavorful, crispy base reminiscent of toasted sandwich bread.
Step 3: Layer the Filling
-
Distribute the chopped corned beef evenly over the bread base.
-
Add a generous layer of drained sauerkraut.
-
Sprinkle with 1 cup of shredded Swiss cheese.
-
Drizzle the Thousand Island dressing over the layers.
Each layer should be spread evenly to ensure that every bite captures all the key components of a traditional Reuben.
Step 4: Add Final Layers
-
Add the remaining bread cubes over the top of the casserole.
-
Sprinkle with the remaining 1 cup of Swiss cheese.
-
Add caraway seeds and chopped parsley, if using, for added flavor and presentation.
These final touches replicate the nutty rye notes and add a visual appeal to the dish.
Step 5: Bake
-
Bake uncovered for 30 to 35 minutes, or until the cheese is melted, the top is golden, and the casserole is bubbling around the edges.
Your kitchen will smell like a gourmet deli—only better.
Step 6: Cool and Serve
-
Allow the casserole to rest for 5 to 10 minutes before slicing. This helps the layers firm up slightly for clean, neat servings.
-
Serve warm as-is, or pair with a side like a green salad or crisp dill pickle slices.

Pro Tips for Reuben Bake Success
1. Rinse the Sauerkraut Well
This ensures your casserole doesn’t become overly sour or soggy. Place it in a colander and rinse under cold water, then pat dry with paper towels.
2. Choose the Right Bread
A sturdy rye or pumpernickel holds up best to the baking process. Avoid very soft sandwich breads that may become mushy.
3. Customize Your Cheese
Try a 50/50 mix of Swiss and mozzarella for a blend of flavor and meltability. For a smoky spin, use smoked gouda.
4. Add a Crunchy Topping
Sprinkle breadcrumbs, crushed rye crisps, or even crushed pretzels on top for extra texture before baking.
5. Add Pickles or Onions
Some cooks like to add sliced dill pickles or caramelized onions between the meat and cheese for more depth.
6. Make It Ahead
Assemble the full dish up to 6 hours ahead of time. Cover and refrigerate until ready to bake. Allow an additional 5–10 minutes of baking time.
7. Turn It Into Mini Servings
Use ramekins or muffin tins to create individual portions—great for parties or lunch prep.
Suggested Pairings
While this dish is rich and flavorful, it plays well with lighter or tangier sides:
-
Green Salad with Dijon Vinaigrette
-
Crisp Dill Pickles
-
Roasted Brussels Sprouts
-
Tomato Soup
-
Potato Salad or Coleslaw
Each of these adds balance and contrast to the cheesy, savory richness of the bake.
Storing and Reheating Leftovers
Refrigeration
Store any leftover casserole tightly covered in the refrigerator for up to 3 days.
Reheating
Reheat in a 325°F oven for 10–15 minutes, or microwave individual servings for 1–2 minutes. For the crispiest texture, the oven is best.
Freezing Instructions
Reuben Bake freezes well either before or after baking. Wrap tightly with foil and freeze for up to 2 months.
-
To bake from frozen: Add 15–20 minutes to the cooking time and cover with foil for the first half of baking.
-
To reheat from frozen (pre-baked): Allow to thaw overnight in the fridge, then warm in the oven.
