🧾 Ingredients – What You’ll Need

Bread:

8-10 slices rye bread, cubed (about 4-5 cups)
½ cup butter, melted

Filling:

1 pound corned beef, cut into bite-sized pieces
1 (16-ounce) can sauerkraut, drained and rinsed (optional: rinse again for a milder flavor)
2 cups shredded Swiss cheese
½ cup Thousand Island dressing (or Reuben dressing of your choice)
2 tablespoons chopped fresh parsley (optional)
2 teaspoons caraway seeds (optional)

💡 Use marble rye for a more colorful and earthy look, or Jewish rye for authentic deli taste.

👨‍🍳 Instructions – How to Make a Reuben Casserole

Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch rectangular baking dish with cooking spray or butter.

Step 2: Coat the Bread

In a large mixing bowl, toss the cubed rye bread with the melted butter until each piece is lightly coated. This helps create that buttery crunch on top while keeping the bread moist underneath.

Step 3: Layer It Up

Spread half of the buttered bread cubes evenly over the bottom of the greased baking dish.
Layer corned beef pieces across the bread.
Sprinkle sauerkraut on top (if using).
Distribute half of the shredded Swiss cheese.
Drizzle Thousand Island dressing evenly over everything.
Add parsley and caraway seeds (if using) for added flavor and authenticity.
Finish with the remaining bread cubes and Swiss cheese.

Step 4: Bake to Perfection

Bake uncovered in your preheated oven for 30–35 minutes, or until:

The cheese is fully melted and bubbling,
The top bread cubes are golden brown and slightly crisp,
The aroma fills your kitchen with deli goodness.

Let cool slightly before serving.

🥄 Serving Suggestions

This Reuben Bake is a hearty meal all on its own, but here are a few ideas to round it out:

Crisp green salad: A tangy vinaigrette balances the richness of the casserole.
Roasted vegetables: Think carrots, Brussels sprouts, or asparagus.
Pickles or dill spears: Classic deli-style sides that complement the corned beef.
Potato salad or coleslaw: Great for summer barbecues or picnic-style meals.

🛠️ Tips & Variations

This casserole is delicious as-is, but there are plenty of ways to put your own twist on it:

✅ Make It Milder:

Rinse sauerkraut twice to tame its tanginess.
Use Swiss and mozzarella blend for a more neutral cheese flavor.

✅ Add a Kick:

Use spicy Russian dressing instead of Thousand Island.
Mix in a little horseradish or mustard.

✅ Use Up Leftovers:

Great for post-St. Patrick’s Day corned beef.
Rye bread getting stale? This is the perfect use.

✅ Vegetarian Option:

Swap corned beef for seasoned tempeh or mushrooms.
Use plant-based cheese and vegan dressing for a dairy-free version.

🧊 Storage & Reheating

Storage: Let the casserole cool completely before storing. Cover tightly with foil or transfer to an airtight container.

Fridge: Store up to 4 days.
Freezer: Store up to 2 months (wrap tightly).

Reheating:

Oven: Cover with foil and bake at 350°F for 15–20 minutes.
Microwave: Heat individual slices for 1–2 minutes, covered, until warmed through.
