It takes the familiar combination of corned beef, tangy sauerkraut, Swiss cheese, and creamy dressing and transforms it into an easy, hearty casserole that’s perfect for a family dinner, weekend lunch, or casual gathering.

Ingredients
For the Bake
- 1 pound cooked corned beef, thinly sliced or chopped
- 4 cups sauerkraut, well drained and squeezed dry
- 6–8 slices Swiss cheese, or about 2 cups shredded Swiss cheese
- 4–5 slices rye bread, cut into small cubes
- 2 tablespoons butter, melted
- 1 teaspoon caraway seeds, optional
- 2 tablespoons chopped fresh parsley, optional
For the Reuben-Style Sauce
- ½ cup mayonnaise
- ¼ cup sour cream
- 2 tablespoons ketchup
- 1 tablespoon Dijon mustard
- 1 tablespoon sweet pickle relish
- 1 teaspoon lemon juice
- ¼ teaspoon garlic powder
- ¼ teaspoon onion powder
- Salt and black pepper, to taste
How to Make Savory Reuben Bake
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9×13-inch baking dish with cooking spray or a small amount of butter.
Step 2: Make the Reuben Sauce
In a small bowl, combine the mayonnaise, sour cream, ketchup, Dijon mustard, sweet pickle relish, and lemon juice.
Add garlic powder, onion powder, a little black pepper, and salt if needed.
Mix until smooth and creamy.
Taste the sauce and adjust the mustard or pickle relish according to your preference. For a sharper flavor, add another small spoonful of Dijon mustard.
Step 3: Prepare the Bread
Place the cubed rye bread in a bowl.
Drizzle the melted butter over the bread and toss gently to coat.
If you enjoy the traditional flavor of rye bread, sprinkle in the caraway seeds and toss again.
Step 4: Layer the Bake
Spread about half of the cubed rye bread across the bottom of the prepared baking dish.
Add half of the corned beef.
Spread half of the drained sauerkraut over the corned beef.
Drizzle or spoon half of the Reuben sauce over the layer.
Add half of the Swiss cheese.
Repeat the layers with the remaining corned beef, sauerkraut, sauce, and Swiss cheese.
Finish with the remaining buttered rye bread cubes.
Step 5: Bake
Cover the dish loosely with aluminum foil and bake for about 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the cheese is melted and bubbling and the top is lightly golden.
For an extra golden top, place the casserole under the broiler for 1–2 minutes at the end. Watch it carefully because the bread can brown quickly.
Step 6: Rest and Serve
Allow the Reuben Bake to rest for about 5–10 minutes before serving.
This gives the layers a chance to settle and makes the casserole easier to portion.
Garnish with fresh parsley if desired.
Tips for the Best Reuben Bake
Drain the Sauerkraut Well
This is one of the most important steps. Sauerkraut contains plenty of liquid, and excess moisture can make the casserole watery.
After draining it, gently squeeze it with clean paper towels or a kitchen towel.
Don’t Skip the Rye Bread
Rye bread gives this bake its unmistakable Reuben character. It also adds texture and absorbs some of the flavorful sauce.
If you don’t have rye bread, sourdough can work as a substitute, although the flavor will be slightly different.
Use Thinly Sliced Corned Beef
Thinly sliced corned beef distributes more evenly throughout the casserole. If using leftover corned beef, simply chop it into small bite-sized pieces.
Watch the Salt
Corned beef, sauerkraut, Swiss cheese, and prepared condiments can all contain salt. Taste the sauce before adding additional salt.
Let It Rest
Giving the bake several minutes to rest after coming out of the oven helps the layers hold together better when served.
Easy Variations
Creamier Reuben Bake
Add ½ cup softened cream cheese to the sauce for a richer and creamier casserole.
Extra Cheesy Version
Add shredded mozzarella along with the Swiss cheese for extra meltiness.
Turkey Reuben Bake
Replace the corned beef with sliced or chopped cooked turkey for a lighter variation inspired by a turkey Reuben sandwich.
Spicy Reuben Bake
Add a few teaspoons of prepared horseradish or a pinch of crushed red pepper flakes to the sauce.
Low-Carb Version
Skip the rye bread and increase the amount of corned beef, sauerkraut, and cheese. You can also add a layer of sautéed mushrooms for extra substance.
Make It Crunchier
For a particularly crispy topping, combine the rye bread cubes with a tablespoon of grated Parmesan before sprinkling them over the casserole.
What to Serve With Reuben Bake
Because this casserole is rich and savory, fresh and lighter side dishes pair especially well with it.
Try serving it with:
- Green salad
- Coleslaw
- Roasted vegetables
- Steamed green beans
- Pickle spears
- Cucumber salad
- Simple tomato salad
- Roasted potatoes
A crisp green salad with a light vinaigrette is especially good because the acidity balances the richness of the casserole.
Make-Ahead Instructions
You can assemble the casserole several hours ahead of time.
Prepare the layers, cover the baking dish, and refrigerate until you’re ready to bake.
For the best texture, keep the final bread topping separate until just before baking so it doesn’t become overly soft.
If baking directly from the refrigerator, you may need to add approximately 5–10 minutes to the cooking time.
Storage
Allow leftovers to cool and refrigerate them in an airtight container.
The Reuben Bake can generally be refrigerated for 3–4 days.
Reheat individual portions in the microwave for convenience, or place the casserole in a covered oven-safe dish and warm it in a 325°F (165°C) oven until heated through.
For the crispiest topping, reheat uncovered for the final few minutes.
Can You Freeze Reuben Bake?
Yes, but the texture of the sauerkraut and bread may soften somewhat after freezing and thawing.
For best results, freeze portions in airtight freezer-safe containers and use them within about 2–3 months for best quality.
Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use leftover corned beef?
Absolutely. Leftover corned beef is perfect for this recipe. Chop or slice it into small pieces before layering.
Can I use Thousand Island dressing instead of the homemade sauce?
Yes. Thousand Island dressing is a convenient shortcut and works particularly well with the other Reuben ingredients.
Can I use pastrami instead of corned beef?
Yes. Pastrami gives the bake a slightly different, more peppery and smoky flavor while still keeping the basic Reuben profile.
Why is my Reuben Bake watery?
The most common reason is excess moisture from the sauerkraut. Drain and squeeze the sauerkraut thoroughly before adding it to the casserole.
Can I prepare this without rye bread?
Yes. Sourdough, French bread, or another sturdy bread can be used. Rye bread simply provides the most traditional Reuben flavor.
