How to Make Layered Reuben Casserole Bake

Step 1: Prep the Baking Dish and Bread

Start by preheating your oven to 350°F (175°C). Give your 11×7-inch or 9×13-inch baking dish a light coating of cooking spray—you don’t want any of this good stuff sticking! Cut four slices of your rye bread into generous, rustic cubes and scatter them across the bottom of the dish. These will soak up all that delicious custard you’re about to add, making a perfect base.

Step 2: Make the Breadcrumbs

Take your two remaining slices of rye and pulse them in a food processor until you’ve got fine, fluffy crumbs. Set these aside; they’ll add irresistible crunch and extra toasty flavor on top of your finished bake.

Step 3: Layer the Pastrami and Veggies

Go ahead and layer half your pastrami (or corned beef) over the bread cubes. Next, spread the drained sauerkraut and those lovely chopped dill pickles right over the meat. Don’t worry if things look a little rustic—it’s all about layers of flavor! Sprinkle on one teaspoon of caraway seeds to really make those aromas start popping as soon as the bake hits the oven.

Step 4: Add Cheese and More Layers

Pile on two cups of the shredded Swiss cheese, making sure to cover everything. Then, repeat with your remaining pastrami or corned beef right on top, and press down gently with clean hands to settle everything together. Finish with the remaining two cups of Swiss cheese and the last teaspoon of caraway seeds for extra punch.

Step 5: Whisk and Pour the Custard

In a medium bowl, whisk together the milk, beaten eggs, creamy Thousand Island dressing, and yellow mustard. You’re making a pourable custard that will transform everything into a cohesive, spoonable bake—just like magic! Pour this mixture evenly over the entire casserole, nudging with a spoon if necessary to make sure it’s well distributed.

Step 6: Top and Bake

Sprinkle your homemade rye breadcrumbs all over the top for a final flourish. Cover the baking dish snugly with foil—it helps keep in moisture and ensures serious gooey-melty action. Place your Layered Reuben Casserole Bake in the oven and let it bake for 45 minutes, until it’s bubbling at the edges and the center is set.

Step 7: Rest and Serve

Once it’s done, let the casserole rest right on the counter for five minutes. This quick pause helps every layer hold together for perfectly sliceable portions. Serve warm and enjoy those rich, savory aromas wafting through your kitchen!

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, cover the cooled casserole tightly or transfer slices to an airtight container. They’ll keep in the fridge for up to three days and are perfect for quick lunches or a midnight snack.

Freezing

You can freeze Layered Reuben Casserole Bake after baking! Let the casserole cool completely, then wrap it tightly in plastic wrap and foil. Store for up to two months; simply thaw overnight in the fridge before reheating.

Reheating

To bring your casserole back to life, reheat slices in a preheated 350°F oven, covered loosely with foil, for 15-20 minutes, or until warmed through. For extra crispness on top, uncover during the last few minutes. You can also use a microwave for quick single servings—just heat in short bursts!

FAQs

Can I use a different type of bread for the base?

Absolutely! Rye is classic for its tang and caraway flavor, but you can substitute pumpernickel or even sturdy sourdough if you want a twist. Whole grain works too—just keep it robust enough to stand up to the creamy custard.

What’s the difference between pastrami and corned beef in this recipe?

Pastrami has more spice and often a smoky edge, while corned beef is saltier and a bit more mellow. Both work beautifully—pick whichever you (or your deli!) prefers, or mix for an extra-flavorful Layered Reuben Casserole Bake.

How do I prevent the casserole from getting soggy?

Make sure to drain your sauerkraut thoroughly and go easy on extra liquid from the pickles. Using the right amount of bread will also keep things sturdy, so don’t skimp on those cubes or crumbs!

Can I assemble the casserole ahead of time?

Yes, this recipe is super make-ahead friendly! Assemble everything up to the point of baking, cover it tightly, and refrigerate overnight. When ready to cook, let it stand at room temp for about 30 minutes, then bake as directed.

Is Layered Reuben Casserole Bake gluten-free?

It’s not gluten-free as written, but you can easily swap in your favorite gluten-free bread and ensure your dressing and mustard are certified gluten-free. You’ll still get all those classic flavors in every bite!
