Imagine sinking your fork into layers of savory corned beef, tangy sauerkraut, and creamy Swiss cheese, all nestled atop a bed of perfectly toasted rye bread. This isn’t just dinner; it’s a culinary hug on a chilly evening!

It’s the perfect dish for potlucks, family gatherings, or simply a satisfying weeknight meal.

Get ready to experience a symphony of flavors with this delightful Reuben Casserole recipe!
Ingredients:
- 1 pound corned beef, thinly sliced
- 1 (16 ounce) can sauerkraut, rinsed and well drained
- 1 (12 ounce) bottle Russian dressing
- 1/2 cup mayonnaise
- 1 tablespoon Dijon mustard
- 1 loaf rye bread, crusts removed, cubed
- 8 ounces Swiss cheese, shredded
- 1/4 cup butter, melted
- 2 tablespoons chopped fresh parsley, for garnish (optional)
Preparing the Bread Crumbs and Base
Okay, let’s get started! First, we need to prepare our rye bread cubes. This will form the base of our casserole and give it that classic Reuben flavor.
- Preheat your oven to 350°F (175°C). This is important so the casserole bakes evenly.
- Prepare the Rye Bread: Remove the crusts from the loaf of rye bread. This will prevent the crusts from becoming too hard during baking. Cut the bread into approximately 1-inch cubes. You want them to be a manageable size for soaking up the dressing and baking nicely.
- Toast the Bread Cubes (Optional): While not strictly necessary, toasting the bread cubes lightly will prevent them from becoming soggy in the casserole. Spread the bread cubes in a single layer on a baking sheet. Bake for about 8-10 minutes, or until lightly golden brown and slightly crisp. Keep a close eye on them so they don’t burn! Let them cool slightly before proceeding.
- Melt the Butter: In a small bowl, melt the butter. You can do this in the microwave in short bursts (about 30 seconds at a time), or in a small saucepan over low heat. Be careful not to burn the butter.
- Combine Butter and Bread: In a large bowl, toss the bread cubes with the melted butter. Make sure all the bread cubes are evenly coated with butter. This will help them crisp up nicely in the oven and add a delicious richness to the casserole.
Preparing the Reuben Mixture
Now for the heart of the Reuben Casserole the delicious mixture of corned beef, sauerkraut, and dressing!
- Prepare the Corned Beef: If you bought a large piece of corned beef, make sure it’s thinly sliced. Pre-sliced corned beef from the deli works great too! If the slices are very long, you might want to cut them into smaller, more manageable pieces. This will make it easier to distribute them evenly throughout the casserole.
- Drain the Sauerkraut: This is a crucial step! Rinse the sauerkraut thoroughly under cold water. This helps to remove some of the excess saltiness and tanginess. After rinsing, squeeze out as much excess water as possible. You can do this with your hands or by pressing it in a clean kitchen towel. Excess moisture will make the casserole soggy.
- Make the Dressing Mixture: In a medium bowl, combine the Russian dressing, mayonnaise, and Dijon mustard. Whisk them together until they are smooth and well combined. The mayonnaise adds a creamy richness, and the Dijon mustard gives it a little extra zing.
Assembling the Casserole
Time to put everything together! This is where the magic happens, and all those delicious ingredients come together to create a Reuben masterpiece.
- Grease the Baking Dish: Lightly grease a 9×13 inch baking dish. You can use cooking spray or a little bit of butter. This will prevent the casserole from sticking to the dish and make it easier to serve.
- Layer the Ingredients: Now, we’re going to layer the ingredients in the baking dish. Start with half of the buttered rye bread cubes. Spread them evenly across the bottom of the dish.
- Add the Corned Beef: Next, layer half of the thinly sliced corned beef over the bread cubes. Try to distribute it evenly so that every bite has a good amount of corned beef.
- Add the Sauerkraut: Spread the drained sauerkraut over the corned beef. Again, make sure it’s evenly distributed.
- Drizzle with Dressing: Drizzle half of the dressing mixture over the sauerkraut. Use a spoon or spatula to spread it evenly.
- Sprinkle with Cheese: Sprinkle half of the shredded Swiss cheese over the dressing.
- Repeat Layers: Repeat the layers with the remaining rye bread cubes, corned beef, sauerkraut, dressing, and Swiss cheese.
Baking the Casserole
Almost there! Now it’s time to bake the casserole and let all those flavors meld together into a warm, comforting dish.
- Bake the Casserole: Cover the baking dish with aluminum foil. This will help to prevent the top from browning too quickly and ensure that the casserole is heated through.
- Bake for 30 Minutes: Bake in the preheated oven for 30 minutes.
- Remove Foil and Bake Longer: Remove the foil and bake for another 15-20 minutes, or until the cheese is melted and bubbly and the top is lightly golden brown. Keep a close eye on it to prevent burning.
- Let it Rest: Once the casserole is done, remove it from the oven and let it rest for about 10-15 minutes before serving. This will allow the casserole to set slightly and make it easier to cut and serve.
Serving and Enjoying Your Reuben Casserole
The moment we’ve all been waiting for! Time to serve up your delicious Reuben Casserole and enjoy the fruits of your labor.
- Garnish (Optional): If desired, garnish the casserole with chopped fresh parsley for a pop of color and freshness.
- Serve Warm: Serve the Reuben Casserole warm. It’s delicious on its own, or you can serve it with a side salad or some extra Russian dressing for dipping.
- Enjoy! Dig in and enjoy the classic flavors of a Reuben sandwich in a comforting casserole form!
