Ingredients You’ll Need
The magic in this Reuben Casserole Recipe comes from simple, familiar ingredients that complement each other wonderfully. Using good-quality rye bread and well-drained sauerkraut really helps the layers hold together and taste balanced.
- Rye bread: I like using slightly dense rye; it soaks up the custard nicely without turning mushy.
- Pastrami or corned beef: Thinly sliced works best to layer evenly and get that classic deli flavor.
- Sauerkraut: Drain it very well to avoid a soggy casserole—this step makes all the difference!
- Swiss cheese: Shredded melts beautifully, adding that mild nuttiness you expect.
- Dill pickles: Chopped for a bright tang that cuts through the richness.
- Caraway seeds: A little sprinkle adds authentic Reuben flavor without overpowering.
- Milk and eggs: These create the custard base that binds everything together.
- Thousand Island dressing and yellow mustard: The special sauce that brings all layers to life with tang and creaminess.
Variations
I love how versatile this recipe is, and you can easily tweak it to fit your taste or dietary needs. Feel free to experiment—it’s all about making it your own and enjoying the process!
- Turkey Reuben Casserole: I swapped pastrami for deli turkey once and my family went crazy for the lighter twist.
- Vegetarian Version: Try using smoked tempeh or thinly sliced mushrooms instead of meat, plus a bit more mustard for that punch.
- Spicy Kick: Adding a dash of hot sauce or a little chipotle mayo stirred into the dressing layers really wakes things up.
- Gluten-free: Use gluten-free bread and make sure your Thousand Island dressing is GF-certified—just as comforting without the gluten.
How to Make Reuben Casserole Recipe
Step 1: Prep the Bread Layers
Start by preheating your oven to 350°F and greasing your baking dish. I usually go for an 11×7-inch dish for a nice thickness, but 9×13 works if you want a thinner casserole. Cut four slices of rye bread into 2-inch cubes and spread them evenly on the bottom. Then pulse the remaining two slices into fine breadcrumbs using a food processor and set them aside for topping later. This bread base is where all the fun begins!
Step 2: Layer the Goodness
On top of the cubed bread, layer half of your pastrami. Next comes the sauerkraut—make sure it’s well-drained—and sprinkle on the chopped dill pickles along with a teaspoon of caraway seeds. Then scatter half the shredded Swiss cheese. Repeat with the remaining pastrami and more Swiss cheese, sprinkle the last teaspoon of caraway seeds, and press everything gently to help it compact. This layering gives you all the classic Reuben flavors in every bite.
Step 3: Whisk and Pour the Custard
In a medium bowl, whisk together milk, beaten eggs, Thousand Island dressing, and yellow mustard until smooth. Pour this mixture evenly over the casserole layers. This custard soaks into the bread cubes and ties all the flavors together—plus, it bakes into a creamy, cohesive dish that’s just irresistible.
Step 4: Top and Bake
Sprinkle the rye breadcrumbs evenly over the top of the custard layer—this adds a lovely crunchy texture once baked. Cover the dish with foil and bake for 45 minutes. When it’s done, let it rest for about 5 minutes to set up before slicing. I find this resting time crucial; it helps your slices keep their shape and makes serving easier.
Pro Tips for Making Reuben Casserole Recipe
- Drain the Sauerkraut Thoroughly: I learned that excess moisture can turn the casserole soggy, so I press the sauerkraut between paper towels for a few minutes before layering.
- Use Fresh Rye Bread: Slightly stale bread works better for soaking up the custard without falling apart, so don’t skip that step if you can.
- Even Layering: Distribute pastrami and cheese evenly so each bite has a perfect balance of flavors—I push down gently to compact but don’t press too hard.
- Don’t Skip the Resting Time: Letting the casserole sit after baking helps it set and makes slicing much easier without crumbling.
How to Serve Reuben Casserole Recipe
Garnishes
I like to keep it classic with a few extra dill pickle slices and a sprinkle of fresh chopped parsley or green onions on top to brighten the richness. Sometimes a little extra drizzle of Thousand Island dressing on the side adds that perfect finishing touch.
Side Dishes
My go-to sides are simple and fresh—think a crisp green salad with a light vinaigrette or oven-roasted potatoes. Coleslaw is another great option, adding crunch and tang that complements the casserole’s creamy, savory layers.
Creative Ways to Present
For special occasions, I’ve served this in individual ramekins layered just like the big casserole—it’s a fun way to personalize portions and make it feel extra fancy. It also makes plating so much easier when friends are over!
Make Ahead and Storage
Storing Leftovers
Once cooled, I cover leftovers tightly with foil or plastic wrap and keep them in the fridge. It reheats beautifully, so you can enjoy next-day comfort food without losing flavor or texture.
Freezing
I’ve frozen this casserole both baked and unbaked—just be sure to wrap it well with foil and plastic wrap to avoid freezer burn. When you’re ready, thaw overnight in the fridge and bake as usual or reheat if already baked.
Reheating
To keep that crispy topping, I pop leftovers into a 350°F oven uncovered for about 15-20 minutes or until warmed through. Microwaving works too in a pinch, but you might lose some of the crispiness on top.
FAQs
-
Can I use corned beef instead of pastrami for this Reuben Casserole Recipe?
Absolutely! Corned beef works just as well and has a delicious salty-sour flavor that pairs nicely with the sauerkraut and cheese. Just slice it thinly and layer it the same way as pastrami for best results.
-
Is it okay to make this Reuben Casserole Recipe ahead of time?
Definitely! You can assemble the casserole a day ahead and keep it covered in the fridge. When you’re ready to eat, just bake it as directed. This actually helps the flavors meld together beautifully.
-
How important are the caraway seeds in this recipe?
Caraway seeds add that traditional, slightly sweet and anise-like flavor that rounds out the Reuben experience. If you don’t have them, you can omit, but I recommend trying them at least once to see how they enhance the dish.
-
Can I use store-bought Thousand Island dressing for the sauce?
Yes! Store-bought Thousand Island works just fine, especially if you’re short on time. If you want to customize, you can mix it with a bit of mustard as the recipe suggests to balance the flavors.
-
What should I serve with this Reuben Casserole Recipe to keep it balanced?
I like pairing it with lighter sides like a fresh green salad, roasted veggies, or a simple slaw to cut through the richness of the casserole and keep the meal balanced.

This Reuben Casserole Recipe holds a special place in my heart because it combines that nostalgic deli flavor we all love with the ease of a one-dish meal.

Notes

- If you don’t have rye bread, a sturdy wheat bread can be used but it will alter the flavor.
- Allowing the casserole to rest after baking helps it to set and slice more cleanly.
- To make ahead, assemble the casserole up to the breadcrumb topping, cover, and refrigerate overnight before baking.
