Jump to Recipe·Print Recipe

There’s nothing quite like a Reuben sandwich—the crispy rye bread, layers of savory corned beef, melty Swiss cheese, tangy sauerkraut, and that signature creamy Thousand Island dressing. It’s a deli favorite for a reason! But what if I told you that you could enjoy all that deliciousness in a warm, cheesy, and oh-so-comforting Reuben Bake?

This easy-to-make casserole takes everything you love about a Reuben sandwich and transforms it into a baked dish perfect for feeding a crowd. Whether you’re making it for a weeknight dinner, a game-day snack, or a holiday potluck, this dish is guaranteed to disappear fast. Plus, it’s a no-fuss meal that doesn’t require standing over the stove, flipping sandwiches one by one.

So, let’s dive into this simple yet satisfying recipe that will make your kitchen smell like your favorite deli!

Getting Started: Ingredients You’ll Need

Before we jump into layering all that deliciousness, let’s go over what you’ll need to make this Reuben Bake:

Ingredients:
1 loaf of rye bread, cubed
1 lb corned beef, sliced
2 cups sauerkraut, drained
2 cups Swiss cheese, shredded
1 cup Thousand Island dressing
¼ cup melted butter
1 tbsp caraway seeds (optional, but adds that classic rye flavor!)
This ingredient list is as simple as it gets, but trust me—the flavors are anything but basic!

Step 1: Preheat and Prep
The first step is to preheat your oven to 350°F (175°C). This gives you time to assemble everything while your oven gets nice and hot.

Next, grease a 9×13-inch baking dish with butter or cooking spray. This will help prevent sticking and make serving a breeze later on.

Step 2: Start Layering
Now, the fun part begins—building those classic Reuben flavors layer by layer.

Lay down half of the rye bread cubes at the bottom of your greased baking dish. This will be the base of your casserole, soaking up all the delicious flavors as it bakes.
Add half of the corned beef on top of the bread. Spread it out evenly so you get some in every bite.
Spoon half of the drained sauerkraut over the corned beef. This adds that signature tangy crunch that makes a Reuben, well… a Reuben!
Sprinkle half of the Swiss cheese evenly over everything. This is where things start getting extra melty and delicious.
Drizzle half of the Thousand Island dressing over the cheese. This adds a creamy, zesty touch that ties everything together.
Step 3: Repeat the Layers
Once you’ve completed the first layer, simply repeat the process:

More rye bread
More corned beef
More sauerkraut
More Swiss cheese
And the rest of the Thousand Island dressing
At this point, you’ve got a dish that looks just as amazing as it smells—and we’re not even done yet!

Now that we’ve layered all those delicious ingredients—rye bread, corned beef, sauerkraut, Swiss cheese, and creamy Thousand Island dressing—it’s time to add the finishing touches and get this casserole baking!

This next step is where the magic happens. We’re going to infuse the dish with buttery goodness, bake it until the cheese is bubbly and golden, and go over a few tips to make sure your Reuben Bake turns out perfect every single time.

Step 4: The Buttery Finishing Touch
Before your dish goes into the oven, it needs one final touch: melted butter.

Drizzle ¼ cup of melted butter evenly over the top layer. This step helps give the bread cubes that irresistible golden-brown crispness while also adding a rich, buttery flavor that ties everything together.
If you’re a fan of traditional rye bread flavor, sprinkle 1 tablespoon of caraway seeds over the top. Caraway seeds add that signature nutty, slightly peppery taste that makes rye bread so distinctive. This step is totally optional, but if you love a classic Reuben, it’s worth adding!
Step 5: Bake to Perfection
Now, it’s time to get this beauty into the oven!

Place the dish in the preheated oven at 350°F (175°C).
Bake for 25-30 minutes, or until the cheese is melty, bubbly, and golden brown on top.
During this time, the flavors will meld together beautifully. The bread will soak up all the goodness from the Thousand Island dressing and butter, while the cheese melts into that perfectly gooey layer we all love.

Pro Tip: If you like your casserole extra crispy, you can bake it uncovered for the full 30 minutes. If you prefer it a little softer, cover it with foil for the first 15 minutes, then remove the foil for the last 10-15 minutes to let the cheese brown nicely.

Step 6: Let It Rest & Serve
Once your Reuben Bake is out of the oven, resist the urge to dig in immediately! Let it rest for about 5 minutes before serving. This helps everything set up, making it easier to scoop out neat portions.

Serving Suggestions:
Pickles on the side – Just like a classic Reuben sandwich, a few dill pickles on the plate balance out the richness.
Extra Thousand Island dressing – Drizzle a little extra on top for an extra punch of tangy flavor.
A simple green salad – If you want something fresh to go alongside this rich and cheesy dish, a crisp green salad with a light vinaigrette is a perfect pairing.
A dollop of sour cream – Believe it or not, a little sour cream on the side can add a creamy, tangy contrast that works really well with the flavors in this dish.
Bonus Tips for the Best Reuben Bake
✔️ Use fresh rye bread. If your bread is very soft, you can toast the cubes in the oven for 5 minutes before assembling the layers to give them a little extra structure.

✔️ Drain your sauerkraut well. Too much liquid can make the casserole soggy. If your sauerkraut seems extra juicy, press it with a paper towel before adding it to the layers.

✔️ Customize it! Not a fan of Thousand Island dressing? Swap it for Russian dressing or Dijon mustard for a slightly different flavor.

Your Reuben Bake is out of the oven, bubbling with melty Swiss cheese and packed with all the bold, tangy, and savory flavors of a classic Reuben sandwich. Now comes the best part—digging in!

Before we wrap things up, let’s go over some common questions about this dish, plus a few extra tips to help you customize it to your liking.

FAQ: Your Reuben Bake Questions Answered

1. Can I make this ahead of time?
Yes! You can assemble the entire casserole up to 24 hours in advance and store it in the refrigerator covered with foil or plastic wrap. When you’re ready to bake, let it sit at room temperature for 15-20 minutes, then bake as directed.

2. How do I store and reheat leftovers?
Leftovers should be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and bake at 300°F (150°C) for about 15 minutes, or microwave individual portions for 1-2 minutes until heated through.

3. Can I freeze Reuben Bake?
Absolutely! After assembling the casserole (but before baking), cover it tightly with foil and freeze for up to 2 months. When ready to bake, let it thaw overnight in the fridge, then bake as usual.

4. What if I don’t like sauerkraut?
No problem! If you’re not a fan of sauerkraut, you can substitute it with sautéed onions and mushrooms, shredded cabbage, or even coleslaw mix for a milder, crunchier texture.

5. Can I use a different type of cheese?
Yes! While Swiss cheese is traditional for a Reuben, you can swap it for Gruyère, provolone, mozzarella, or even sharp white cheddar for a unique twist.

6. Is there a way to make this dish lighter?
If you want a lighter version, you can use reduced-fat Swiss cheese, light Thousand Island dressing, and lean corned beef. You can also substitute whole-grain rye bread for extra fiber.

7. Can I make this gluten-free?
Yes! Just swap out the rye bread for your favorite gluten-free bread and ensure your Thousand Island dressing is also gluten-free.
