For the Dressing
- 1/2 cup mayonnaise
- 1/4 cup Thousand Island dressing (or Russian dressing)
- 1 tablespoon Dijon mustard
- Salt and pepper, to taste
For the Topping
- 2 tablespoons melted butter
- 1/4 cup grated Parmesan cheese (optional)
- 2 teaspoons caraway seeds (optional, for added rye flavor)
Equipment You’ll Need
- 9×13 inch baking dish
- Mixing bowls
- Spatula
- Knife and cutting board
- Whisk
Step-by-Step Directions
1. Prepare the Ingredients
- Preheat the Oven: Start by preheating your oven to 375°F (190°C).
- Cube the Bread: Cut the rye bread into bite-sized cubes and set aside. You want enough to cover the base of your baking dish in a single layer.
- Shred the Corned Beef: If you’re using leftover cooked corned beef, shred or chop it into small pieces. If using deli-style, simply chop it into bite-sized pieces.
- Drain the Sauerkraut: Make sure to drain the sauerkraut well. If it’s too wet, your bake may turn out soggy.
2. Assemble the Reuben Bake
- Layer the Bread: Spread the cubed rye bread evenly across the bottom of your greased 9×13 inch baking dish.
- Add the Corned Beef: Distribute the corned beef evenly over the bread cubes.
- Top with Sauerkraut: Sprinkle the drained sauerkraut over the corned beef layer.
- Sprinkle the Cheese: Add the shredded Swiss cheese as the final layer, covering the sauerkraut completely.
3. Make the Dressing
- Whisk the Dressing: In a small bowl, whisk together the mayonnaise, Thousand Island dressing, Dijon mustard, salt, and pepper. You can adjust the seasonings to taste.
- Drizzle Over the Bake: Pour the dressing mixture evenly over the layered ingredients in the baking dish.
4. Add the Topping
- Prepare the Topping: In a small bowl, combine the melted butter, grated Parmesan cheese, and caraway seeds (if using).
- Brush Over the Bake: Brush the buttery topping over the surface of the casserole for extra flavor and crunch.
5. Bake the Reuben Casserole
- Bake: Place the dish in the preheated oven and bake for 25-30 minutes, or until the cheese is melted and bubbly and the top is golden brown.
- Cool and Serve: Allow the casserole to cool for a few minutes before slicing and serving. This helps the layers set and makes it easier to dish out.
Tips for the Best Homemade Reuben Bake
- Drain the Sauerkraut: Make sure the sauerkraut is well-drained to avoid sogginess. You can even press it lightly with a paper towel.
- Make it Crispier: For a crispy top, finish the casserole under the broiler for 2-3 minutes after baking, but keep a close eye on it to prevent burning.
- Customize the Cheese: While Swiss cheese is traditional, feel free to mix in or substitute with mozzarella, provolone, or even a sharp cheddar for a twist.
- Low-Carb Option: For a low-carb version, skip the bread and layer the corned beef, sauerkraut, and cheese directly in the baking dish. Bake the same way!
How to Store and Reheat
Storing:
- In the Fridge: Store leftovers in an airtight container in the fridge for up to 3-4 days.
Reheating:
- In the Oven: Reheat in the oven at 350°F (175°C) for about 10-15 minutes, or until heated through.
- In the Microwave: For a quicker option, reheat individual portions in the microwave for 1-2 minutes, though the bread may not stay as crisp.
Freezing:
- Freezer-Friendly: You can freeze the baked Reuben casserole by wrapping it tightly in plastic wrap and aluminum foil. It will keep in the freezer for up to 2 months. To reheat, thaw in the fridge overnight and bake at 350°F until heated through.
What to Serve with Reuben Bake
This Homemade Reuben Bake is a hearty dish on its own, but if you want to pair it with something, here are a few ideas:
- Pickles: A side of dill pickles or pickled vegetables adds a bright, tangy contrast to the rich casserole.
- Coleslaw: Serve with a simple cabbage coleslaw for a crunchy, refreshing side.
- Potato Salad: A creamy or mustardy potato salad complements the flavors of the corned beef and sauerkraut beautifully.
- Beer: Pair with a cold, crisp lager or a dark beer like a stout to match the hearty flavors of the Reuben bake.
