The way the cheese bubbles up and the edges crisp? Absolute magic. Plus, no slippery rye bread to try juggling here! I can’t wait to walk you through how to build this ridiculously satisfying layered bake, perfect for weeknight dinners or casual weekend hangs when you want something warm and totally crave-worthy.

Quick Facts

Yield: Serves 6
Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes

Ingredients

For the Main Dish:

12 oz sliced corned beef, chopped or shredded
1 1/2 cups sauerkraut, well-drained and patted dry
2 cups shredded Swiss cheese
4 cups rye bread cubes (day-old is best)
1/2 cup Thousand Island dressing (store-bought or homemade)
2 tbsp unsalted butter, melted
1 tsp caraway seeds (optional, for authentic flavor)

For the Sauce / Garnish (if applicable):

Extra Thousand Island dressing for serving
Fresh parsley, chopped (optional garnish)

How I Make It

Step 1:

Preheat your oven to 350°F and grease a 9×13-inch baking dish. In a large bowl, toss the rye bread cubes with the melted butter and caraway seeds so everything is coated and ready to soak up those flavors while baking.

Step 2:

Now, it’s layer time! Start by spreading a thin layer of Thousand Island dressing across the bottom of the baking dish. This adds moisture and tang that will marry all the flavors together beautifully.

Step 3:

Next, sprinkle half the rye cubes evenly over the dressing, then scatter half the corned beef over that. Follow with half the sauerkraut, making sure it’s drained well to avoid sogginess. Top this with one cup of the Swiss cheese.

Step 4:

Repeat the layers — rye bread cubes, corned beef, sauerkraut — and finish off with the remaining Swiss cheese on top. This double-layer technique makes sure every bite is packed with those classic Reuben flavors.

Step 5:

Cover the dish tightly with foil and bake for 20 minutes. Then, remove the foil and bake for another 10 minutes to get that glorious cheesy crust bubbling and slightly golden.

Step 6:

Let the bake rest for about 5 minutes before slicing. This allows it to set up nicely and makes serving easier. For extra flair, drizzle a little Thousand Island dressing on top and sprinkle chopped parsley before serving.

Variations & Tips

Use rye bread with caraway seeds for more authentic flavor or swap for pumpernickel for a deeper, richer taste.
Swap Thousand Island with Russian dressing if you like it a little tangier.
If your sauerkraut is too wet, give it a quick squeeze in a clean kitchen towel to avoid watery layers.
Add a thin layer of Dijon mustard under the bread cubes if you want a subtle spicy kick.
Leftovers reheat well in the oven — just cover loosely with foil to prevent drying out.
For a lower-fat version, substitute half of the cheese with a lighter Swiss or Gruyere cheese.

How I Like to Serve It

This bake is perfect for chilly evenings, maybe paired with a crisp green salad and a cold beer to cut through the richness. It also shines at casual gatherings or game day parties where everyone can grab a hearty slice with their hands or fork. And trust me—leftover slices make an amazing breakfast the next day when warmed up with a fried egg on top.

Notes

Store leftovers covered in the fridge for up to 3 days. Reheat at 325°F until warmed through.
Make sure your corned beef is fully cooked and sliced thinly — deli-style works great here.

Closing: When you want all those irresistible Reuben flavors without the mess of sandwiches, this bake always hits the spot and makes dinner feel a little extra special.
