Quick Facts

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

Ingredients

For the Main Dish:

• 1 lb corned beef, chopped or shredded
• 1 1/2 cups sauerkraut, drained well
• 2 cups shredded Swiss cheese
• 4 cups cubed rye bread (day-old works best)
• 2 tbsp unsalted butter, melted
• 1/2 cup Thousand Island dressing (store-bought or homemade)

For the Sauce / Garnish (if applicable):

• Extra Thousand Island dressing, for serving (optional)

How I Make It

Step 1:

Start by preheating your oven to 350°F. Lightly butter or spray a 9×13-inch baking dish—this helps the bread cubes crisp up nicely without sticking.

Step 2:

In a large bowl, toss the rye bread cubes with the melted butter until they’re evenly coated. This step is key to getting that golden, toasty texture that balances the creamy cheese and juicy meat.

Step 3:

Layer half the bread cubes in the bottom of your prepared dish. Then sprinkle half of the chopped corned beef over the bread, followed by half of the sauerkraut and 1 cup of the shredded Swiss cheese.

Step 4:

Drizzle half of the Thousand Island dressing evenly over the layers. Repeat the layering one more time—bread, corned beef, sauerkraut, cheese, and finish with the dressing.

Step 5:

Cover the dish loosely with foil and bake for 20 minutes. After that, remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden on top. You’re looking for those beautiful browned edges that mean flavor city!

Step 6:

Let it cool for a few minutes before serving—this helps everything set up and makes it easier to slice. Serve warm with a little extra Thousand Island on the side if you want that classic tangy kick.

Variations & Tips

• Swap rye bread for pumpernickel or sourdough for a different flavor profile.
• Use pastrami or turkey instead of corned beef for a twist on the classic.
• Sauté sauerkraut with some onions and caraway seeds before adding for extra depth.
• Add a sprinkle of paprika or smoked paprika on top before baking for a smoky touch.
• Make it vegetarian by trading corned beef for a hearty mushroom mix and extra Swiss.
• If you like it extra creamy, stir a little sour cream into the Thousand Island dressing before layering.

How I Like to Serve It

This Reuben bake is fantastic on a chilly evening paired with a crisp dill pickle and a simple green salad for freshness. It also works wonderfully for casual gatherings—just set it on the table and watch everyone dig in. Bonus points if you serve it alongside a cold beer or a fun cocktail with a hint of spice!

Notes

• Store leftovers covered in the fridge for up to 3 days; reheat gently in the oven to keep that crisp top.
• For easy prep, use leftover corned beef or chopped deli meat to save time.

Closing: This classic Reuben bake is one of those foolproof recipes that always delivers comfort, flavor, and that perfect balance of tangy and cheesy goodness—making every bite feel like a little celebration at home.
