Ingredients You’ll Need

Getting this Reuben Casserole Recipe right starts with a few simple yet essential ingredients that work together to create a depth of flavor, texture, and color. Each item plays an important role, whether it’s the rye bread’s robust bite or the Swiss cheese’s gooey richness, so make sure you have everything on hand.

• 6-8 slices light rye bread (cubed): The hearty base that holds all the flavors together, with just the right amount of texture.
• 2 Tablespoons unsalted butter (melted): Adds moisture and richness to brown the bread cubes beautifully.
• 1/2 teaspoon garlic powder: Offers a subtle savory depth that enhances the overall flavor.
• 1/2 teaspoon onion powder: A gentle, sweet note to complement the garlic and the tangy sauerkraut.
• 1 teaspoon caraway seeds: Classic in rye bread dishes, these seeds provide a distinctive aromatic touch.
• 1/2 teaspoon salt: Brings out the natural flavors and balances the tangy elements.
• 1/4 teaspoon black pepper: A hint of heat to awaken every bite.
• 1 pound deli corned beef (coarsely chopped): The star protein that adds savory, tender bites throughout.
• 14.5 ounces can sauerkraut (drained and rinsed): The signature tangy ingredient that brightens up the casserole.
• 1 1/2 cups Thousand Island dressing: Creamy, slightly sweet, and perfectly complements the other layers.
• 2 cups shredded Swiss cheese (divided): Melts into a luscious blanket of cheesy goodness on top and within the casserole.

How to Make Reuben Casserole Recipe

Step 1: Preheat and Prepare Your Baking Dish

First things first, preheat your oven to 375°F (190°C). To make sure your casserole doesn’t stick, lightly grease a 9×13-inch baking dish with butter or a nonstick spray. This step prevents frustrating cleanups and helps the edges of your casserole brown nicely—trust me, those crunchy parts are worth it.

Step 2: Season the Rye Bread Cubes

In a large mixing bowl, toss the cubed rye bread with melted butter, garlic powder, onion powder, caraway seeds, salt, and black pepper. This coating ensures the bread soaks up all the flavors while adding its own kick. Stir everything gently until the bread pieces are evenly coated—this is where the magic begins.

Step 3: Layer the First Bread Base

Take half of your seasoned bread cubes and spread them out evenly on the bottom of your greased baking dish. This layer acts like a foundation, soaking up all the delicious juices from the next layers, creating a wonderful texture contrast.

Step 4: Add the Corned Beef

Scatter half of the chopped corned beef over your bread layer, distributing it evenly. This ensures every portion of casserole gets that iconic meaty flavor that we all love in a Reuben.

Step 5: Spread the Sauerkraut

Now, grab half of your drained and rinsed sauerkraut and spoon it evenly over the corned beef. The sauerkraut adds an irresistible tanginess that is a key signature flavor in this dish.

Step 6: Dollop and Smooth the Thousand Island Dressing

Pour ¾ cup of Thousand Island dressing over the sauerkraut. Use a spatula to gently smooth it out, covering the entire layer. This creamy dressing ties the savory and tangy layers together beautifully.

Step 7: Sprinkle Swiss Cheese

Next, sprinkle 1 cup of shredded Swiss cheese across the dressing layer. Swiss cheese melts wonderfully and adds that nutty, slightly sweet flavor, melting into all the layers below.

Step 8: Create the Second Layer

Repeat the previous layers—start with the remaining bread cubes, then the rest of the corned beef, sauerkraut, dressing, and finish with the final cup of Swiss cheese on top. Layering creates a casserole that fills every bite with the perfect balance of ingredients.

Step 9: Bake Until Golden and Delicious

Cover the dish tightly with aluminum foil and bake for 20 minutes. Removing the foil partway through baking allows the cheese on top to melt perfectly and develop a gorgeous golden hue. Continue baking uncovered for an additional 10-15 minutes or until bubbly and bubbling with melted cheese.

Step 10: Let it Rest and Serve

Once out of the oven, let your Reuben Casserole cool for 5-10 minutes. This rest time helps everything set up and makes it easier to scoop out beautiful portions—plus, it lets those flavors develop even more. After this quick pause, it’s time to dig in!

How to Serve Reuben Casserole Recipe

Garnishes

A few simple garnishes can elevate this Reuben Casserole Recipe to something extra special. Consider sprinkling chopped fresh parsley or green onions on top for a fresh pop of color and subtle herbal brightness. A few extra caraway seeds scattered lightly can also hint at the bread’s aromatic notes without overwhelming the dish.

Side Dishes

This casserole is so hearty, it pairs wonderfully with crisp, light sides. Think a fresh green salad with a lemon vinaigrette to cut through the richness or some roasted root vegetables for a cozy complement. If you want to keep things super classic, a plate of crunchy dill pickles or coleslaw will echo the tangy flavors of the sauerkraut and dressing perfectly.

Creative Ways to Present

For a casual family dinner, scoop the casserole straight from the baking dish onto plates for a cozy, communal feel. If you’re serving guests, consider layering individual portions into mini casserole dishes or ramekins for elegant presentation. You could even top each serving with a fried egg for brunch — the creamy yolk adds an unexpected but delightful richness.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers of this Reuben Casserole Recipe, store them in an airtight container in the refrigerator. The flavors tend to meld even more after a day, making reheated portions just as delicious as fresh. Consume within 3-4 days for the best taste and texture.

Freezing

Want to save some for later? This casserole freezes beautifully. After baking and cooling completely, portion it into freezer-safe containers or wrap tightly with aluminum foil and plastic wrap. It can be frozen for up to 2 months. When ready, thaw overnight in the refrigerator before reheating.

Reheating

To bring your leftover Reuben Casserole Recipe back to life, reheat it gently in a 350°F (175°C) oven until warmed through, usually about 20-25 minutes. Cover loosely with foil to prevent the top from getting too browned. You can also microwave smaller portions, but the oven method keeps that satisfying texture intact.

FAQs

Can I use different bread instead of rye?

While light rye bread gives the casserole its traditional flavor, you can swap it for other breads like pumpernickel or even sourdough if you want to experiment. Just keep in mind the bread’s texture and density to ensure it soaks up the layers without getting too soggy or falling apart.

Is there a vegetarian version of this Reuben Casserole Recipe?

Absolutely! You can replace the corned beef with hearty sautéed mushrooms or use a plant-based deli meat substitute to enjoy similar textures and flavors. Just make sure any replacements have bold seasoning to stand up to the tangy sauerkraut and creamy dressing.

Can I make this dish spicier?

Definitely. Adding a pinch of crushed red pepper flakes to the bread mixture or mixing some horseradish into the Thousand Island dressing can give this casserole an exciting kick without overpowering the classic Reuben flavors.

What type of Swiss cheese works best?

Look for good melting Swiss cheese like Emmental or Jarlsberg for a smooth, creamy melt with slightly nutty undertones. Avoid pre-shredded cheese with anti-caking agents as it sometimes doesn’t melt as well.

How do I prevent the casserole from becoming soggy?

Draining and rinsing the sauerkraut thoroughly is key. The butter-coated bread cubes also help create a moisture barrier. Additionally, letting the casserole rest after baking allows excess moisture to be absorbed, keeping each serving beautifully textured.

Final Thoughts

This Reuben Casserole Recipe is one of those rare meals that feels both indulgent and comforting without any fuss. It’s perfect for feeding a crowd or simply treating yourself to the best parts of a classic sandwich in an all-in-one dish.
