Easy Reuben Casserole Recipe with Thousand Island Dressing

This Reuben casserole recipe with Thousand Island dressing brings all the flavor of a Reuben sandwich into an easy recipe the whole family will love.

It’s baked in a casserole dish and makes delicious individual portions—perfect for weeknights or St. Patrick’s Day celebrations.

Ingredients You’ll Need

• 1 pound chopped corned beef (ask for thick slices at the deli counter)
• 16 oz sauerkraut, rinsed and drained
• 1 cup Thousand Island dressing (I like Ken’s Steakhouse for that rich Thousand Island dressing flavor)
• 2½ cups shredded Swiss cheese
• 6 slices of rye bread (marbled rye is my favorite)
• Butter or nonstick cooking spray
  

How to Make This Easy Reuben Casserole

Step 1: Prep the Baking Dish

Preheat your oven to 400°F. Lightly grease a 9×13 casserole dish with nonstick cooking spray. This helps keep everything from sticking and adds a nice finish to the bottom layer.

Step 2: Build the Layers

Spread the chopped corned beef across the bottom of the prepared baking dish. This is your savory foundation.

Take your sauerkraut and rinse it well. Drain the excess liquid, press it through a strainer, and pat it dry with a paper towel. Nobody wants soggy sauerkraut.

Sprinkle the tangy sauerkraut evenly over the corned beef.

Step 3: Add That Creamy Thousand Island Flavor

Drizzle your Thousand Island dressing over the top of the well-drained sauerkraut. Spread it gently with a spoon or spatula to coat the layer. This step brings the creamy, sweet-tangy kick that mimics the classic flavor of a Reuben sandwich.

Step 4: Cheese, Bread, and Toasty Finish

Top with shredded Swiss cheese. Next, cube your slices of rye bread. You can butter them before cubing or wait until after and brush the cubes with melted butter. Either way, this adds the crispy texture we all love.

Sprinkle the rye bread cubes over the top of the casserole. Spray the bread cubes with a non-stick cooking spray or butter the bread before cutting it into cubes. The results are a toasty rye bread topping that bring everything together for this simple comfort food. 

Step 5: Bake Until Golden Brown

Slide your dish into the oven. Bake for 15–20 minutes, or until the bread cubes are golden brown and the cheese has melted to bubbly perfection.

Serving and Storage Tips

Cut into individual portions and serve hot. This dish tastes just like a Reuben sandwich but in casserole form—warm, cheesy, and satisfying. It is a complete meal all in one. 

Store leftovers in an airtight container in the fridge. Reheat in the oven or microwave for a quick lunch or dinner. Reuben lovers will really enjoy this delicious one dish meal. Serve it with a simple salad and you are set.
