Ingredients

1 tablespoon unsalted butter, plus more for greasing the dish
8 slices rye bread, preferably marbled, crusts removed, cut into 1-inch cubes (about 4 cups)
3 large eggs, beaten
1/4 cup milk (whole or 2%)
1 tablespoon Dijon mustard
1 teaspoon caraway seeds (optional, for bread base)
1 pound thinly sliced corned beef, deli-style or leftover, roughly chopped or torn into bite-sized pieces
2 pounds (about 32 ounces) sauerkraut, well-drained and gently squeezed dry
1 cup Thousand Island dressing, plus extra for serving (store-bought or homemade)
12 ounces Swiss cheese, freshly shredded (about 3 cups)
1/2 cup panko breadcrumbs (for topping, optional)
2 tablespoons melted butter (for topping, optional)
Fresh parsley, chopped, for garnish

Instructions

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter.
In a large mixing bowl, combine the cubed rye bread, beaten eggs, milk, Dijon mustard, and caraway seeds (if using). Toss gently until the bread cubes are evenly coated.
Press the bread mixture evenly into the bottom of the prepared baking dish. This will form your sturdy, flavorful base.
Evenly spread the well-drained and squeezed sauerkraut over the rye bread base. Ensure the layer is relatively flat.
Distribute the chopped or torn corned beef pieces over the sauerkraut layer. Try to get an even spread so every bite has some meat.
Drizzle 1 cup of Thousand Island dressing evenly over the corned beef layer.
Sprinkle 2 cups of the shredded Swiss cheese over the dressing layer.
If using a panko breadcrumb topping, in a small bowl, toss the panko breadcrumbs with 2 tablespoons of melted butter until coated.
Sprinkle the remaining 1 cup of shredded Swiss cheese over the top of the casserole. If using, sprinkle the buttered panko breadcrumbs evenly over the Swiss cheese.
Cover the baking dish loosely with aluminum foil.
Bake for 25 minutes.
Remove the foil and continue to bake for another 15-20 minutes, or until the cheese is melted, bubbly, and golden brown on top, and the edges are lightly browned. If you desire a deeper golden-brown crust, you can carefully broil for the last 2-3 minutes, watching it very closely to prevent burning.
Once baked, remove the casserole from the oven and let it rest for 10-15 minutes before serving. This allows the layers to set, making it easier to cut and serve neat slices.
Garnish with fresh chopped parsley before serving, and offer extra Thousand Island dressing on the side for those who want more.

Cooking Tips and Variations

For the best Reuben Bake, proper sauerkraut preparation is paramount. Always ensure you drain and squeeze the sauerkraut as dry as possible. Excess moisture will lead to a watery, soggy casserole, detracting from the desired texture. After draining from the can or jar, you can place it in a colander and press down firmly, or even wrap it in a clean kitchen towel and twist to extract maximum liquid. When layering, avoid pressing down too hard on the ingredients, as this can compress them and make the bake dense. Aim for relatively even layers that allow the heat to circulate and melt the cheese uniformly. If you notice the cheese browning too quickly during the uncovered baking phase, you can loosely tent it with foil again to prevent over-browning while the rest of the bake finishes cooking through. A slight rest after baking is also crucial; it allows the cheese to firm up slightly and the internal juices to redistribute, making for cleaner, more intact slices.

This recipe is wonderfully adaptable. For the bread base, while rye is traditional, you can experiment with pumpernickel bread for a richer, darker flavor, or even a sturdy sourdough. If you’re looking for a low-carb alternative, you can omit the bread base entirely and simply start with the sauerkraut layer, though the texture will be different. Beyond corned beef, consider using thinly sliced pastrami for a slightly spicier, smokier note, or even turkey pastrami for a lighter option. For a twist on the cheese, Gruyere or even a sharp white cheddar could offer an interesting flavor profile, though Swiss is classic for a reason. If you like a little heat, a pinch of red pepper flakes mixed into the Thousand Island dressing or scattered over the corned beef layer can add a welcome kick. To make individual portions, assemble the layers in oven-safe ramekins or even large muffin tins, adjusting baking times as needed. For an extra boost of flavor, some people like to mix a tablespoon of Worcestershire sauce into their Thousand Island dressing.

Storage and Reheating

To store any leftover Classic Reuben Bake, allow it to cool completely to room temperature. Once cooled, cover the baking dish tightly with plastic wrap or aluminum foil, or transfer individual portions to airtight containers. The bake can be stored in the refrigerator for up to 3-4 days. It is not generally recommended to freeze this casserole, as the sauerkraut can become mushy and the cheese texture may change upon thawing and reheating.

For reheating, individual slices or portions can be warmed in the microwave for 1-2 minutes, or until heated through. Be careful not to overheat, as this can make the corned beef tough and the cheese rubbery. For larger portions or to maintain a crispier topping, preheat your oven or toaster oven to 300-325°F (150-160°C). Place the leftover bake in an oven-safe dish, cover loosely with foil (to prevent drying out), and bake for 15-25 minutes, or until thoroughly heated through and the cheese is bubbly again. Uncover for the last few minutes if you want to re-crisp the topping. Reheating in an air fryer at around 325°F (160°C) for 8-12 minutes can also yield excellent results, especially for crisping up the top layer.

Frequently Asked Questions

Can I make this Reuben Bake ahead of time?

Yes, you can certainly assemble the Reuben Bake a day in advance. Prepare all the layers in the baking dish, then cover it tightly with plastic wrap and refrigerate. When ready to bake, remove it from the refrigerator about 30 minutes before baking to allow it to come closer to room temperature, then bake as directed, potentially adding 5-10 minutes to the covered baking time to ensure it heats through evenly.

What kind of Thousand Island dressing should I use?

You can use your favorite store-bought Thousand Island dressing, or make your own for a fresher taste. Homemade Thousand Island typically involves a base of mayonnaise and ketchup, with relish, finely minced onion, and sometimes a dash of Worcestershire sauce or hot sauce. If you prefer a Russian dressing, which is often used in Reubens, it’s a very similar dressing but might include horseradish or chili sauce for a different kick.

My sauerkraut is very salty. Should I rinse it?

Some brands of sauerkraut can be quite salty. If yours tastes excessively salty, you can rinse it briefly under cold water before draining and squeezing dry. Rinsing can help reduce the sodium content and temper the tanginess, but be sure to drain and squeeze it extremely well afterward to prevent a watery casserole.

Can I use different bread for the base or topping?

While rye bread is traditional and highly recommended for its flavor, you can experiment. Pumpernickel bread offers a darker, slightly sweeter alternative for the base. For the topping, while panko breadcrumbs provide a great crunch, you could also crush some rye crackers or even more rye bread for a homemade breadcrumb topping. If you’re avoiding bread, simply omit the bread base and panko topping, though the texture and structure of the bake will be different.
