Ingredients You’ll Need

This Reuben Casserole Recipe keeps things simple but packs big flavor thanks to each carefully chosen ingredient. From the rye bread’s distinctive bite to the sharpness of Swiss cheese, here is everything you need to create this tasty layered delight.

• Light rye bread (6-8 slices, cubed): Provides a chewy base full of that classic Reuben flavor and soaks up all the delicious layers.
• Unsalted butter (2 tablespoons, melted): Helps the bread cubes crisp up beautifully while adding richness.
• Garlic powder (1/2 teaspoon): Adds a subtle savory note without overpowering the other ingredients.
• Onion powder (1/2 teaspoon): Enhances the depth of flavor with gentle sweetness and warmth.
• Caraway seeds (1 teaspoon): Infuse a traditional touch that pairs perfectly with rye bread and corned beef.
• Salt (1/2 teaspoon): Balances all the layers and pulls flavors together.
• Black pepper (1/4 teaspoon): Adds a hint of mild heat to brighten the dish.
• Deli corned beef (1 pound, coarsely chopped): The star protein that brings that unmistakable Reuben sandwich taste.
• Sauerkraut (14.5 ounces, drained and rinsed): Offers tang and a little crunch to cut through the richness.
• Thousand Island dressing (1 1/2 cups): Creamy and slightly sweet, it binds the layers with classic Reuben flavor.
• Swiss cheese (2 cups shredded, divided): Melts into gooey goodness, creating those irresistible cheesy pockets.

How to Make Reuben Casserole Recipe

Step 1: Prep Your Oven and Baking Dish

Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or a nonstick spray to prevent sticking and help with even browning. Getting this ready upfront makes the layering process smooth and mess-free.

Step 2: Season the Rye Bread Cubes

In a large bowl, toss the cubed rye bread with melted butter, garlic powder, onion powder, caraway seeds, salt, and black pepper. This simple seasoning mix elevates the bread, making every bite flavorful and aromatic. Make sure each cube is evenly coated for that perfect seasoned crunch after baking.

Step 3: Build the First Layer

Spread half of the seasoned bread cubes evenly across the bottom of your baking dish. This creates the foundation for your casserole, soaking up the flavors while providing a satisfying texture contrast with the layers to come.

Step 4: Add Corned Beef

Scatter half of the coarsely chopped deli corned beef over the bread layer. Distributing it evenly ensures each portion will have that savory, meaty punch that’s essential for a true Reuben experience.

Step 5: Layer the Sauerkraut

Spoon half of the drained, rinsed sauerkraut on top of the corned beef. The sauerkraut adds a delightful tang and a slight crunch that balances the richness from the meat and cheese.

Step 6: Spread Thousand Island Dressing

Pour ¾ cup of the Thousand Island dressing over the sauerkraut layer. Gently smooth it out with a spatula to cover the entire tacky surface. This dressing brings a creamy, slightly sweet contrast that ties all these bold flavors together.

Step 7: Add Swiss Cheese

Sprinkle 1 cup of shredded Swiss cheese evenly over the dressing layer. This cheese melts down into a wonderful layer of melty goodness that binds the ingredients and adds a nutty flavor.

Step 8: Repeat the Layers

Now, repeat the exact same process with the remaining bread cubes, corned beef, sauerkraut, dressing, and finish with the last cup of Swiss cheese on top. This double layer is what makes this casserole a hearty meal so perfect for sharing.

Step 9: Bake the Casserole

Cover the dish tightly with aluminum foil and bake for 20 minutes. Then remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is bubbly and golden on top. This baking process melds the flavors and crisps the edges just right.

Step 10: Let It Rest and Serve

Allow the casserole to cool for about 5 to 10 minutes before cutting into it. This rest time helps everything set up, making it easier to serve and enjoy without all the ingredients sliding apart. Then dig in and enjoy the warm, comforting layers of this fantastic Reuben Casserole Recipe!

Garnishes

While this casserole stands beautifully on its own, a sprinkle of freshly chopped fresh parsley or dill adds a pop of color and a hint of herbaceous brightness. You can also serve it with extra Thousand Island dressing or a few pickles on the side to amp up the classic Reuben vibe.

Side Dishes

Pair this hearty casserole with light, refreshing sides like a crisp green salad dressed with lemon vinaigrette or roasted vegetables. These options help balance the richness of the dish and round out your meal perfectly.

Creative Ways to Present

For a fun twist at dinner parties, serve the Reuben Casserole Recipe in individual ramekins for personalized portions. You could also layer it in clear glass casserole dishes so the beautiful layers are visible and tempting guests right from the table.

Make Ahead and Storage

Storing Leftovers

Reuben Casserole leftovers keep wonderfully in an airtight container in the refrigerator for up to 3 days. The flavors marry even more after sitting, making for delicious next-day meals or snacks.

Freezing

This casserole freezes well before baking. Assemble in a foil pan, cover tightly, and freeze for up to 3 months. When ready, thaw overnight in the fridge and bake as directed, adding a few extra minutes if needed to ensure it’s warmed through.

Reheating

Reheat leftovers gently in a preheated oven at 350°F (175°C) until warmed through and the cheese is bubbly again, usually about 15-20 minutes. Avoid microwaving if you want to keep the crispy texture and nicely melted cheese intact.

FAQs

Can I use a different type of bread?

Light rye bread is traditional and provides that iconic flavor for a Reuben, but you could try marble rye or another sturdy rye bread if you prefer. Avoid very soft or thin breads since they won’t hold up to the layers as well.

Is Thousand Island dressing essential?

Thousand Island dressing is a key flavor component that gives the Reuben Casserole its classic zing. You can use a homemade version or store-bought, but substituting with other dressings will change the dish’s signature taste.

Can I make this vegetarian?

While the corned beef is central to the traditional recipe, you could substitute with plant-based corned beef alternatives or extra sauerkraut and Swiss cheese for a vegetarian twist, though it won’t have the classic Reuben flavor exactly.

How spicy is this casserole?

This casserole has a mild flavor profile with gentle seasoning like garlic and onion powder and a touch of black pepper. If you want a little heat, you can add a pinch of cayenne pepper or spicy mustard on the side.

What’s the best way to slice and serve?

After allowing the casserole to cool, use a sharp knife to cut it into squares or rectangles. Serve with a spatula to keep the layers intact and enjoy each cheesy, tangy bite.
