  • 8 slices of rye bread, cubed

Kitchen Equipment Needed

To make this Reuben Bake, you’ll need just a few basic kitchen tools:

  • Cutting board and knife (for cubing bread and slicing meat)

  • Cheese grater

  • Mixing bowl (optional for combining ingredients)

  • 9×13-inch baking dish

  • Aluminum foil

  • Oven

Minimal tools, maximum flavor. It’s that simple.

Step-by-Step Instructions

Prep Steps

  1. Preheat your oven to 350°F (175°C).

  2. Grease a 9×13-inch baking dish with cooking spray or butter.

  3. Cube the rye bread into bite-sized pieces.

  4. Shred or slice the corned beef as desired.

  5. Drain and rinse the sauerkraut thoroughly to remove excess brine and avoid a soggy bake.

Cooking Steps

  1. Layer half of the rye bread in the bottom of your prepared baking dish.

  2. Add half of the corned beef, followed by half the sauerkraut.

  3. Sprinkle half the cheese over the top, then drizzle half of the Thousand Island dressing evenly.

  4. Repeat the layers with the remaining bread, beef, sauerkraut, cheese, and dressing.

  5. Cover with foil and bake for 25–30 minutes, or until the cheese is bubbly and melted throughout.

  6. Let rest for 5 minutes before slicing and serving.

This resting time helps everything set up just enough so it slices cleanly while still being rich and gooey.

Tips for the Best Reuben Bake

  • Use day-old rye bread for better texture. Fresh bread can become too soggy.

  • Squeeze out excess moisture from the sauerkraut. You can even blot it with paper towels.

  • Customize your layers. Like extra cheese or more meat? Go for it. This recipe is forgiving.

  • Make it spicy. Add a few dashes of hot sauce or pepper jack cheese for a kick.

  • Toast the bread cubes before baking for added crunch.

How to Store and Reheat Leftovers

This Reuben Bake stores beautifully, making it great for meal prep or leftovers.

Storing:

  • Allow the bake to cool completely.

  • Store in an airtight container in the refrigerator for up to 4 days.

Reheating:

  • Oven method (recommended): Cover with foil and reheat at 350°F for 15–20 minutes.

  • Microwave: Place a slice on a microwave-safe plate and heat for 1–2 minutes, covered with a paper towel.

Avoid freezing, as the bread texture may suffer when thawed.

Suggested Pairings

Reuben Bake is hearty, tangy, and rich. Here are some perfect pairings to round out your meal:

Sides:

  • Dill pickles or pickled red onions

  • German potato salad

  • Coleslaw for freshness and crunch

  • Simple green salad with a light vinaigrette

Drinks:

  • Crisp lager or German-style pilsner

  • Dry Riesling or light red wine like Pinot Noir

  • Iced tea or sparkling water with lemon for a non-alcoholic option

  • Low-Carb Reuben Bake: Skip the bread and layer all other ingredients into a greased dish for a keto-friendly option.

Frequently Asked Questions

Can I make Reuben Bake ahead of time?

Yes! Assemble the entire dish, cover tightly with foil or wrap, and refrigerate up to 24 hours in advance. Bake as directed when ready.

What’s the best bread to use if I don’t like rye?

Sourdough or pumpernickel are great alternatives. Even hearty whole wheat can work in a pinch.

How can I make this gluten-free?

Use gluten-free rye-style or multigrain bread and double-check the dressing and sauerkraut labels to ensure they’re gluten-free.

Can I freeze Reuben Bake?

It’s not ideal. While you can freeze it, the bread may become soggy or mushy after thawing and reheating. For best results, enjoy fresh or refrigerated leftovers.

Is this recipe kid-friendly?

Surprisingly, yes! If your kids aren’t into sauerkraut, consider reducing the amount or substituting with sautéed cabbage.
