Ingredients You’ll Need

Pulling together this Layered Reuben Casserole Bake is a snap, thanks to a short ingredient list loaded with bold flavors and fantastic texture. Every item plays a vital role—from the earthy rye to the sharp Swiss and tangy sauce, each adds something special you don’t want to miss.

• Rye bread (6 slices): The classic foundation, it soaks up flavor and gives the dish its signature hearty texture, plus crunch from breadcrumbs on top for the perfect bite.
• Pastrami or corned beef (1 lb, thinly sliced): Rich, savory meat is the heart of this casserole, so choose quality slices for the best flavor.
• Sauerkraut (1 can, 14.5 oz, drained): Brings a bright, tangy kick that balances all the cheesy, meaty goodness beautifully.
• Swiss cheese (4 cups, shredded): Melts into gooey ribbons that bind the layers together and keep every forkful creamy and rich.
• Caraway seeds (2 tsp, divided): These tiny seeds deliver a nutty, mildly licorice note that sets a good Reuben apart from the rest—don’t skip them!
• Dill pickles (1 cup, chopped): Adds bites of crunch and an acidic zing that really wakes up the whole casserole.
• Milk (1 cup): Helps keep the casserole moist and gives it a tender, custardy richness.
• Eggs (3 large, beaten): Act as the binder that holds all the flavorful layers together when baked.
• Thousand Island–style creamy dressing (1/3 cup): Adds sweetness, tang, and an unmistakably “Reuben” flavor that ties everything together.
• Yellow mustard (1/4 cup): A punch of tangy sharpness and color that takes the flavor to another level.

How to Make Layered Reuben Casserole Bake

Step 1: Prep and Preheat

Start by heating your oven to 350°F (175°C) so it’s nice and toasty when your casserole is ready to bake. Give your 9×13-inch (or 11×7-inch) baking dish a light spray with cooking oil—this will ensure easy cleanup and perfect portions that won’t stick.

Step 2: Build the Bread Base

Cut 4 slices of your rye bread into rough 2-inch cubes. Scatter them evenly across the bottom of your greased dish, creating a soft layer that will soak up all the delicious juices and form the hearty base. Take your remaining 2 slices and pulse in a food processor until you have fine, fluffy breadcrumbs—set these aside for an irresistibly crispy topping at the end.

Step 3: First Layers – Meat, Vegetables, and Flavor Boosts

Lay half of your thinly sliced pastrami or corned beef right on the bread cubes—the warmth will fuse the flavors together as they bake. Next, evenly spread the drained sauerkraut and your chopped dill pickles over the meat. Sprinkle 1 teaspoon of caraway seeds across this layer for that unmistakable “Reuben” flavor.

Step 4: Time for Melty Cheese

Spread half (2 cups) of your shredded Swiss cheese evenly over the sauerkraut and pickles. This layer will get deliciously gooey and help bind everything underneath together as it bakes.

Step 5: Repeat and Top

Layer the rest of the pastrami or corned beef on next, gently pressing down to help everything settle. Follow up with the final 2 cups of Swiss and another sprinkle (1 teaspoon) of caraway seeds. You’ll have a gloriously stacked Layered Reuben Casserole Bake just waiting for its finishing touches!

Step 6: Whisk and Pour the Custard

In a bowl, vigorously whisk together the milk, beaten eggs, Thousand Island dressing, and yellow mustard. Make sure it’s smooth and creamy—this custardy mix will soak through your layers, binding everything and packing each bite with flavor. Pour this mixture evenly over your assembled casserole, letting it seep into every nook and cranny.

Step 7: Add Crunch and Bake

Finish by sprinkling your fresh rye breadcrumbs over the top. Cover the whole dish tightly with foil and bake for 45 minutes—a little patience means bubbly, golden perfection. Let it cool for 5 minutes after baking to help everything set, then slice into thick, satisfying pieces. Serve warm for the ultimate comfort food!

How to Serve Layered Reuben Casserole Bake

Garnishes

A shower of freshly chopped dill or parsley brightens each plate, while a few extra dill pickle slices on top deliver crunch and classic deli vibes. If you want to go all out, a light dusting of cracked black pepper or an extra drizzle of Thousand Island dressing right before serving will have your guests swooning.

Side Dishes

Pair your Layered Reuben Casserole Bake with a crisp green salad tossed in a simple vinaigrette, or complement the richness with roasted potatoes or tangy vinegar coleslaw. Even a cup of tomato soup brings out the sandwich-like comfort of this bake. Keep sides light and fresh to balance every luscious, cheesy forkful.

Creative Ways to Present

Transform each serving into an open-faced sandwich by placing it on a toasted round of rye, or cut your Layered Reuben Casserole Bake into appetizer squares and skewer with a cocktail pickle for parties. Little ramekins make for adorable, individual portions—perfect for brunch or a deli-themed lunch spread!

Make Ahead and Storage

Storing Leftovers

Leftover Layered Reuben Casserole Bake keeps exceptionally well. Cover the cooled casserole tightly with foil or transfer slices to an airtight container. Store in the refrigerator for up to 4 days; the flavors only get better as they mingle!

Freezing

You can freeze this casserole either whole or in individual portions. Wrap thoroughly with plastic wrap, then foil, to guard against freezer burn. It will keep for up to three months. Thaw overnight in the fridge before reheating for best results.

Reheating

To reheat, cover your casserole loosely with foil and bake in a 350°F oven until heated through (about 20 minutes for a whole bake, or 8–10 minutes for individual pieces). You can also microwave slices in 30-second bursts, but the oven is best for restoring that golden, crisp top.

FAQs

Can I substitute the pastrami or corned beef with another meat?

Absolutely! While pastrami and corned beef are classic, thinly sliced turkey or roast beef can work in a pinch. Just keep the slices thin for layering and flavor balance.

Is it necessary to use rye bread, or can I try something different?

Rye is traditional and imparts a distinct flavor, but pumpernickel or a sturdy artisanal whole grain bread make tasty alternatives if you’re feeling adventurous. The caraway seeds will still give you that classic Reuben character!

My family doesn’t love sauerkraut—can I leave it out?

You can swap the sauerkraut for a well-drained coleslaw mix, or simply use less kraut if you’re looking to mellow the tang. The casserole is flexible, though omitting it will slightly change the signature Reuben profile.

Can I make Layered Reuben Casserole Bake ahead for a party?

Definitely! Assemble everything (except for the breadcrumb topping) up to one day ahead, cover tightly, and refrigerate. Just sprinkle the breadcrumbs right before baking so the top stays crispy and golden.

What’s the best way to get clean slices when serving?

Letting your Layered Reuben Casserole Bake rest for five minutes after baking is key. Use a sharp, serrated knife to cut neat portions, and a spatula to lift out delicious, intact squares every time!
