A Reuben Bake Casserole brings all the cozy flavors of a classic Reuben sandwich into one warm baking dish. You get savory corned beef, tangy sauerkraut, creamy dressing, melty Swiss cheese, and crisp rye bread in every bite. There is no need to build individual sandwiches or stand over a skillet.
This version is made in layers, so it is easy to put together even if you are new to casseroles. The key is to drain the sauerkraut well and spread each layer evenly. That keeps the finished bake from becoming soggy.
Plan on about 15 minutes of active prep and roughly 30 minutes in the oven. The result should be hot in the center, bubbly around the edges, and golden on top. Serve it for a weeknight dinner, game-day meal, or a relaxed weekend supper.
Gather your ingredients and a 9×13-inch baking dish, and you are ready to start.

Gather the Reuben Bake Casserole ingredients
Having everything ready before you start keeps the layering quick and neat. Measure the dressing and cheese, chop the corned beef into small pieces, and cut the rye bread into roughly 1-inch cubes. You can use deli corned beef or leftover cooked corned beef. If your bread is very fresh, leave the cubes uncovered for a few minutes so the surface dries slightly and can hold the casserole juices better.
Drain the sauerkraut thoroughly
Sauerkraut carries a lot of liquid, and that extra moisture can make the bottom of the casserole soggy. Place the sauerkraut in a colander and press it gently with the back of a spoon to remove excess liquid. You do not need to make it completely dry. The goal is to remove the liquid that would otherwise collect in the baking dish.
Prepare the rye bread
Toss the rye bread cubes with 2 tablespoons of melted butter, 1/2 teaspoon garlic powder, and 1/4 teaspoon black pepper. Use a large bowl so you can turn the cubes without crushing them. Coat them lightly rather than soaking them. The bread will absorb some moisture during baking while the butter helps the exposed pieces brown and crisp.
Layer the bread in the baking dish
Grease a 9×13-inch baking dish lightly with butter or cooking spray. Spread the seasoned rye bread cubes across the bottom in one even layer. Try not to leave large empty spaces, but do not pack the bread down tightly either. A loose layer gives the dressing and juices room to move through the casserole as it bakes.
Add the corned beef and sauerkraut
The bread should now have a full layer of toppings without being pressed down. Scatter the chopped corned beef evenly over the bread, followed by the drained sauerkraut. Spread both ingredients toward the corners of the dish so each serving gets a mix of salty meat and tangy cabbage. Keep the layers loose; pressing them down can make the finished casserole dense.
If your corned beef is very salty, use a little less added seasoning on the bread. The sauerkraut and dressing already bring plenty of flavor.
Spread the dressing over the layers
Spoon the 1 cup of Thousand Island or Russian dressing across the sauerkraut and corned beef. Use the back of a spoon or a small spatula to spread it into a thin, even layer. Do not stir the casserole together. Keeping the ingredients layered gives you distinct bites of rye bread, corned beef, sauerkraut, and creamy dressing throughout the finished bake.
Avoid pouring the dressing into one thick mound in the center. An uneven layer can leave some parts dry while making the middle too wet.
Cover with Swiss cheese
Sprinkle 2 cups of shredded Swiss cheese evenly over the dressing. Work from the center toward the edges so the entire surface gets covered. Keep the cheese layer fairly even rather than piling it in the middle. This gives the casserole a melted top in every serving and helps protect the ingredients underneath from drying out during baking.
Bake the casserole until bubbly
Heat the oven to 350°F and place the uncovered casserole on the center rack. Bake for about 25–30 minutes, or until the cheese is fully melted and the edges are bubbling. The center should be hot before you take it out. If the cheese browns too quickly, loosely cover the dish with foil for the remaining baking time.
Rest the casserole before serving
Give the baked casserole about 5–10 minutes to rest on a heat-safe surface before cutting into it. This short pause lets the melted cheese settle and gives the layers time to firm up slightly. Serve it warm while the Swiss cheese is still soft and stretchy. A wide spatula works well for lifting portions from the dish without breaking apart the layers.
Troubleshooting
| If This Happens | Try This |
|---|---|
| The casserole is watery | Drain and press the sauerkraut well before layering it. |
| The bread feels too soft | Use slightly stale rye bread and avoid adding extra dressing. |
| The cheese browns too fast | Loosely cover the dish with foil for the rest of the baking time. |
| The center is not hot | Return the casserole to the oven for another 5–10 minutes. |
FAQ
Can I use leftover corned beef?
Yes. Leftover cooked corned beef works very well. Chop it into small pieces so it spreads evenly through the casserole.
Can I use a different cheese?
Swiss cheese gives the classic Reuben flavor, but mild white cheeses that melt well can work if needed.
Should I rinse the sauerkraut?
You can rinse it if you prefer a milder flavor, but it is not required. The important part is to drain it well before adding it to the casserole.
Can I prepare the casserole ahead of time?
You can assemble the layers ahead of baking and keep the covered dish refrigerated. For best results, let the chilled dish sit out briefly while the oven heats, then bake until the center is hot.
How should I store leftovers?
Let the casserole cool, then cover and refrigerate leftovers. Reheat individual portions until hot throughout. The bread may soften more after refrigeration, but the Reuben flavors will still be there.
