Ingredients You’ll Need

This Reuben casserole is built with layers of classic components and a few surprise twists for texture and creaminess.

Ingredient Notes

• Corned Beef: Leftover home-cooked corned beef or sliced deli-style both work very well.
• Sauerkraut: Rinse and drain thoroughly; for a lighter flavor, lightly rinse and squeeze out excess brine.
• Rye Bread: Caraway-marble rye is traditional, but regular rye or pumpernickel can be substituted.
• Cream Soup: If you avoid condensed soups, try a homemade white sauce in place of cream of chicken.

Step-by-Step Directions

This Reuben casserole is easy to assemble and comes together in just a few simple steps. Here’s how to do it:

1. Preheat the oven to 350°F (177°C). Grease a 9-by-13-inch baking dish generously with butter.
2. Make the Hash Brown Layer: In a large mixing bowl, combine 1/4 cup of melted butter, cream of chicken soup, milk, 1 cup of shredded Swiss cheese, Thousand Island dressing, caraway seeds, salt, and pepper. Add thawed hash browns and stir to coat evenly.
3. Spread the Mixture: Spoon the hash brown mix evenly across the bottom of the prepared baking dish and smooth into a layer.
4. Layer the Fillings: Distribute the corned beef over the hash browns. Scatter the well-drained sauerkraut on top. Sprinkle the remaining Swiss cheese over the sauerkraut.
5. Add the Rye Topping: Toss cubed marbled rye bread with the remaining melted butter. Scatter these cubes over the top of the casserole as a crunchy finishing layer.
6. Bake and Finish: Bake, uncovered, for 45–50 minutes, or until the casserole is bubbling and the bread cubes are toasted golden brown.
7. Garnish and Serve: Let rest a few minutes before serving. Garnish with fresh chopped parsley and an extra drizzle of Thousand Island dressing if desired.

Pro tip: Allowing the casserole to rest for 10–15 minutes before cutting ensures cleaner slices.

Tips, Variations, and Make-Ahead Options

• Rinsing Sauerkraut: For a milder tang, rinse and squeeze your sauerkraut before adding it. For extra zip, leave as is.
• For Extra Crunch: Broil the casserole for the last 2–3 minutes to further brown the bread topping, but watch closely to prevent burning.
• Cheese Swaps: Instead of Swiss, try gruyère or provolone for different melting properties and flavor.
• No Cream of Chicken? Use cream of mushroom or a homemade béchamel.
• Gluten-Free Option: Use gluten-free rye-style bread and a gluten-free creamy soup.
• Vegetarian Twist: Substitute roasted mushrooms or tempeh for the corned beef, and use a vegetarian cream soup.

Make-Ahead and Storage

• To Make Ahead: Assemble all layers in your baking dish (reserve the bread topping separately), cover, and refrigerate up to 24 hours. Add the bread just before baking to keep it crisp.
• Storing Leftovers: Store tightly covered in the fridge for up to 3 days. Bread topping may soften; reheating in the oven restores some crispness.
• Freezer Friendly: Assemble (without bread topping), wrap tightly, and freeze for up to one month. Thaw, add bread, and bake as directed.

Serving Suggestions and Storage

• Classic Accompaniments: Serve with extra Thousand Island or Russian dressing, dill pickle spears, and a simple green salad to cut through the casserole’s richness.
• For Brunch: Pair with poached eggs or a tangy fruit salad.
• For Lunch: Serve warm slices alongside coleslaw or a crisp apple slaw for balance.

Frequently Asked Questions (FAQs)

Q: Can I use Pastrami instead of Corned Beef?

A: Absolutely! Pastrami brings a smoky, spiced note that works well in this casserole. Slice or dice thinly for best texture.

Q: Is it necessary to rinse the sauerkraut?

A: Rinsing sauerkraut is optional. Rinsing tempers the tanginess and reduces salt; leaving it un-rinsed yields a sharper flavor.

Q: Can I make this casserole gluten-free?

A: Yes, simply use gluten-free rye-style bread (or omit the bread) and a gluten-free condensed soup. Always check ingredient labels.

Q: What other cheeses work well?

A: Gruyère, provolone, or even mozzarella may be substituted for Swiss, though the flavor will differ slightly.

Q: How do I keep the bread crisp?

A: Add the buttered bread cubes just before baking, and avoid covering the casserole while baking to ensure the topping crisps.
