If you're craving the classic flavors of a Reuben sandwich but want to feed a crowd or simplify your mealtime, this Traditional Reuben Casserole is your go-to dish. It’s packed with hearty ingredients, the tang of sauerkraut, and the creaminess of Swiss cheese, all baked to bubbly perfection.
Corned beef provides the savory, meaty backbone of the dish. Using thin slices helps create layers that melt together for a flavorful bite. The sauerkraut adds a tangy zest, balancing the richness of the meat and cheese. It’s important to rinse it to avoid overpowering the other flavors. Thousand Island dressing adds a creamy, slightly sweet note that complements the sauerkraut perfectly. Swiss cheese is the melty star here, offering a mild nutty flavor that ties the whole casserole together. Rye bread cubes mimic the sandwich experience, providing that classic rye flavor and a bit of texture. Finally, unsalted butter helps to crisp up the top layer of bread and cheese, giving the casserole a golden finish.
First things first, preheat your oven to 350°F (175°C). While that's warming up, take a moment to grease your 9x13 inch casserole dish to prevent sticking. Now, let's build our layers: spread half of the rye bread cubes evenly at the bottom of the dish. This forms the base that soaks up all the delicious juices.
Next, layer half of the corned beef slices over the bread. You want to cover it well, but don’t worry if it’s not perfect. Then comes the sauerkraut, spread it evenly over the beef. Drizzle half of the Thousand Island dressing over this layer to add a creamy touch.
Now, onto the cheese! Lay half of the Swiss cheese slices over the dressing. Repeat these layers with the remaining ingredients, finishing with a generous top layer of cheese. Finally, drizzle the melted butter over the top to ensure a crispy, golden crust.
Cover the dish with foil and pop it in the oven for 25 minutes. This allows everything to meld together. Afterward, remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown. Once done, let it cool for about 5 minutes before serving. This short wait helps everything set up nicely.
This casserole pairs wonderfully with a crisp green salad dressed with a light vinaigrette. The fresh greens complement the rich casserole and add a refreshing contrast. For a hearty meal, you could also serve it with roasted potatoes or a side of pickles to enhance the traditional Reuben flavors.
