• Large eggs: Binding agents that, along with the milk, add structure and heartiness.

How to Make Layered Reuben Casserole Bake

Step 1: Prep the Baking Dish and Bread

Preheat your oven to 350°F (175°C) and grease a 9×13-inch or 11×7-inch baking dish with cooking spray. Cube 4 slices of rye bread into rough 2-inch pieces and scatter them evenly on the bottom—these form the delicious base. Pulse the remaining 2 slices in a food processor or crumble them by hand into fine breadcrumbs and set aside; these will make a crisp, flavorful topping.

Step 2: Layer the Meat, Sauerkraut, and Pickles

Take half your pastrami or corned beef and drape it evenly over the rye bread cubes. Next, sprinkle the drained sauerkraut across the meat, followed by the chopped dill pickles for a burst of brightness. Sprinkle one teaspoon of caraway seeds over this layer to tie all those classic deli flavors together.

Step 3: Add a Blanket of Cheese

Spread half (2 cups) of the shredded Swiss cheese over the veggie and meat layer, letting the cheese tumble into every nook and cranny—this ensures gooey satisfaction in every bite of your Layered Reuben Casserole Bake.

Step 4: Second Meat and Cheese Layer

Layer on the rest of the pastrami or corned beef, pressing down gently to compact the casserole just a tad. Top that with the remaining shredded Swiss cheese and sprinkle the last teaspoon of caraway seeds over the top—a finishing touch that fills your kitchen with aroma as it bakes.

Step 5: Whisk and Pour the Egg Mixture

In a mixing bowl, whisk together the milk, beaten eggs, Thousand Island–style dressing, and yellow mustard until fully blended. This mixture is your creamy secret weapon: it soaks into the bread and brings the casserole together. Pour it slowly and evenly over everything in the dish, giving it time to seep into every delicious layer.

Step 6: Add the Breadcrumb Topping

Take those rye breadcrumbs you prepped earlier and sprinkle them evenly across the top. They’ll bake into a golden, slightly crunchy lid that contrasts beautifully with the creamy, melty center.

Step 7: Bake to Bubbling Perfection

Cover the baking dish with foil and slide it into your preheated oven. Bake for 45 minutes, letting the cheesy, savory aroma fill your kitchen. Once baked, let the casserole rest for 5 minutes before slicing and serving—this helps everything set up perfectly for clean, satisfying servings of Layered Reuben Casserole Bake.

How to Serve Layered Reuben Casserole Bake

Garnishes

Accentuate your casserole with snipped fresh chives, a sprinkle of extra caraway seeds, or even a scatter of chopped dill pickles on top. For an extra zippy bite, put a little extra Thousand Island or grainy mustard on the side for dipping—the perfect touch for lovers of bold flavor.

Side Dishes

This Layered Reuben Casserole Bake needs only simple companions. Try it with crisp oven-roasted potatoes, a fresh green salad, or even some classic deli-style potato chips. If you’re going all out, add a light coleslaw or some tangy pickled vegetables to balance the richness.

Creative Ways to Present

For gatherings or game days, slice the casserole into small squares and spear each piece with a toothpick for party-perfect Reuben bites. If you’re serving a crowd, bring the casserole dish straight to the table and let everyone scoop up generous helpings. For a retro deli feel, serve with a stack of extra rye toast wedges and little bowls of pickles and dressing alongside your Layered Reuben Casserole Bake.

Make Ahead and Storage

Storing Leftovers

Allow any remaining casserole to cool to room temperature before transferring slices to an airtight container. Store in the refrigerator for up to 4 days—this bake reheats beautifully, making it a fabulous next-day lunch or quick dinner solution.

Freezing

The Layered Reuben Casserole Bake can absolutely be frozen! Once baked and cooled, wrap portions tightly in foil or plastic wrap and stash them in freezer-safe bags. They’ll keep up to three months, making it perfect for whenever a comfort food craving hits.

Reheating

Reheat individual slices in the microwave for a couple of minutes or in a 350°F oven, covered with foil, until warmed through (about 15 minutes if thawed, or 30 minutes if frozen). If you want that crispy top again, uncover for the last few minutes of baking.

FAQs

Can I substitute pastrami with corned beef?

Absolutely! Both bring an authentic deli vibe, so feel free to use whichever you love most or even combine the two for maximum depth of flavor.

Does the sauerkraut need to be rinsed?

Rinsing isn’t required, but do drain it very well to prevent extra liquid from making the casserole soggy. If you’re not a major fan of tang, a gentle rinse can help mellow the flavor.

Is it possible to make this casserole ahead and bake later?

Yes, you can fully assemble the Layered Reuben Casserole Bake (except for the breadcrumbs) up to one day ahead, refrigerate it covered, and add the breadcrumbs just before baking. This makes it perfect for entertaining or saving time on busy days.

Can I use a different kind of bread?

Rye bread is traditional and adds unique flavor, but in a pinch, hearty pumpernickel or even sourdough are great alternatives. Just choose a sturdy bread that can hold up to all the delicious layers.

How do I keep the casserole from getting too soggy?

The key is thoroughly draining your sauerkraut and pickles. Also, use a hearty rye bread, and make sure to let the casserole rest after baking to help it set nicely for slicing.
