Ingredients for Reuben Casserole Recipe in Family Circle

Classic deli ingredients transform into a comforting baked dish with minimal effort.

The corned beef is the foundation here. Delicounter slices from a quality butcher or Boar’s Head brand at the grocery store provide the best texture—avoid canned for this recipe. Sauerkraut should be fresh-packed (found in the refrigerated section), not shelf-stable. For the Swiss cheese, Emmental or Gruyère offer superior melt and flavor compared to pre-shredded blends.

No rye bread? Pumpernickel works beautifully for a darker, richer flavor. If sauerkraut is too tangy, rinse it thoroughly under cold water. Thousand Island can be swapped for Russian dressing (slightly spicier). For a lighter version, low-fat cheese and Greek yogurt dressing reduce some richness without sacrificing flavor. The caraway seeds add authenticity—skip if you dislike their anise-like taste.

Assemble the casserole just before baking—it doesn’t hold well uncooked. Leftovers keep for 3-4 days refrigerated and reheat best covered with foil. The flavors actually improve overnight, making this ideal for meal prep. Freeze portions for up to 2 months if desired.

Step-by-Step Instructions for Reuben Casserole

This method preserves the classic deli flavors in a convenient baked format.

Step 1: Prepare the Sauerkraut Mixture

In a large bowl, combine the 16 oz Sauerkraut (drained and rinsed) with the 0.5 whole Onion (finely diced) and 1 tsp Caraway Seeds. I squeeze the sauerkraut gently in my hands to remove excess moisture before mixing—this prevents a watery casserole.

Stir in the 2 cloves Garlic Cloves (minced) and 0.5 tsp Black Pepper for a fragrant base. The caraway seeds add that authentic deli flavor, but you can omit them if preferred. This mixture forms the tangy foundation of your casserole.

Step 2: Create the Creamy Dressing Base

In a separate bowl, whisk together the 1 cup Thousand Island Dressing and 2 tbsp Yellow Mustard until smooth. The mustard adds a sharp tang that balances the richness of the dressing.

I fold in 4 oz Swiss Cheese (half of the total) to create a creamy, cheesy sauce that will bind the layers together. This step ensures every bite has that signature Reuben flavor profile without being overly heavy.

Step 3: Build the Casserole Layers

Lightly grease a 9×13-inch baking dish with some of the 2 tbsp Butter. Start with a layer of the 6 slices Rye Bread (cubed and lightly toasted) on the bottom, then spread half the sauerkraut mixture evenly over the bread.

Add the 1 lb Corned Beef (thinly sliced) in an even layer, followed by the remaining sauerkraut. Drizzle the dressing mixture over the top, then sprinkle with the remaining 4 oz Swiss Cheese. The layering ensures every forkful contains all the classic elements.

Step 4: Bake to Perfection

Cover the dish with foil and bake in a preheated 375°F oven for 25 minutes. This initial covered baking allows the flavors to meld together without the top drying out.

Remove the foil and bake for an additional 10-15 minutes until the cheese is bubbly and golden brown and the edges are crisp. Let it rest for 5 minutes before serving to allow the layers to set.

Garnish with the 0.5 cup Pickles (chopped) for a fresh, tangy contrast that completes the Reuben experience. Serve warm for the best texture and flavor.

Flavor Customization for This Recipe

Spice It Up

Swap the 2 tbsp Yellow Mustard for Dijon mustard to add a more robust, spicier kick. I also love adding ½ tsp smoked paprika to the dressing mixture for a subtle, smoky depth that complements the corned beef beautifully. 🌶️

Extra Cheesy Twist

Mix in 4 oz shredded Gruyère with the Swiss cheese for a nuttier, richer flavor. The Gruyère melts wonderfully and adds a gourmet touch. For even more indulgence, sprinkle ¼ cup grated Parmesan on top during the last 5 minutes of baking.

Meat Variations

If you want to experiment, try pastrami instead of corned beef for a peppery, more intense flavor. For a lighter option, use turkey pastrami—it’s leaner but still packed with that deli-style taste. I’ve found both work beautifully in this casserole.

Veggie Boost

Add ½ cup sautéed mushrooms or diced bell peppers to the sauerkraut mixture for extra texture and nutrients. The mushrooms soak up the flavors wonderfully, while bell peppers add a touch of sweetness and crunch.

Sauerkraut Swap

If sauerkraut isn’t your thing, try shredded cabbage sautéed with 1 tbsp apple cider vinegar and 1 tsp sugar for a milder, slightly sweet alternative. It won’t have the same tang but still adds that classic crunch. 💡

Crunchy Topping

Before baking, sprinkle ½ cup crushed potato chips or panko breadcrumbs mixed with 1 tbsp melted butter on top for an irresistible crispy topping. It adds a delightful contrast to the creamy layers below.
