What are Pioneer Woman Reuben Casserole?
This recipe transforms the beloved Reuben sandwich into a layered casserole.

Essential Ingredients for Pioneer Woman Reuben Casserole
Here are the seven ingredients you need, straight from the recipe. Each one plays a key role in building the classic Reuben flavor profile.
- 1 lb deli-sliced corned beef, cut into 1-inch pieces — This is the hearty protein that gives the casserole its savory base. Ask for thick slices at the deli counter for easier cutting. Avoid very fatty pieces, as noted in the recipe, for a cleaner texture.
- 1 can (14 oz) sauerkraut, drained and squeezed dry — The tangy backbone of the dish. Squeezing out as much liquid as possible keeps the casserole from turning watery. If you prefer a milder sourness, rinse the sauerkraut briefly under cold water before squeezing.
- 8 oz Swiss cheese, shredded (about 2 cups) — Swiss cheese melts beautifully and adds a nutty, slightly sweet flavor that balances the tangy kraut and dressing. Shred your own from a block for the best melt — pre-shredded cheese often contains anti-caking agents.
- 1/2 cup Russian dressing (or Thousand Island) — This creamy, tangy dressing ties everything together. Russian dressing is typically a bit spicier and less sweet than Thousand Island, but either works perfectly here.
- 2 cups rye bread cubes (from 3-4 slices, crusts on, cut into 1/2-inch cubes) — The signature Reuben bread gives the topping its distinctive flavor and crunch. Leaving the crusts on adds texture and prevents the cubes from disintegrating during baking.
- 2 tbsp unsalted butter, melted — Brushed over the bread cubes before toasting, it adds richness and helps them brown evenly in the oven.
- 1/4 tsp freshly ground black pepper — A simple seasoning that enhances all the other flavors without overpowering them.
Equipment You’ll Need
- 8×8-inch baking dish or 1.5-quart casserole dish — This is the correct size for the recipe. A larger dish will spread the layers too thin and may dry out the casserole.
- Small rimmed baking sheet — For toasting the rye bread cubes. The rim prevents the buttered cubes from rolling off.
- Nonstick cooking spray — A light coating on the baking dish ensures the casserole releases easily after baking.
- Chef’s knife and cutting board — You’ll need a sharp knife to cut the corned beef into 1-inch pieces and to slice the rye bread into cubes.
- Large spoon or spatula — For layering the ingredients evenly into the dish.
Instructions to Make Pioneer Woman Reuben Casserole
Follow these six steps exactly, and you’ll have a perfectly layered, bubbly casserole every time. The toasting step is non-negotiable — it makes all the difference in the topping texture.
- Preheat and prep — Preheat your oven to 375°F (190°C). Lightly grease the 8×8-inch baking dish with nonstick spray so nothing sticks.
- Toast the bread cubes — Spread the rye bread cubes on a small rimmed baking sheet. Drizzle with melted butter and toss to coat evenly. Bake for 5 minutes, just until lightly toasted. Set them aside — they’ll go on top later.
- Build the first layer — Arrange half of the corned beef pieces in an even layer on the bottom of the prepared dish. Top with half of the drained sauerkraut, spreading it out so every bite gets some tang.
- Add dressing and cheese — Drizzle half of the Russian dressing over the sauerkraut, then sprinkle with half of the shredded Swiss cheese. Take your time to spread the dressing evenly — globs of dressing can make the casserole overly rich in spots.
- Repeat the layers — Add the remaining corned beef, then the remaining sauerkraut, dressing, and cheese. This double layering ensures every forkful has a balanced mix of all the components.
- Top and bake — Scatter the toasted rye bread cubes evenly over the top. Sprinkle with black pepper. Bake uncovered for 20-25 minutes, until the casserole is hot and bubbly around the edges and the bread cubes are deep golden brown. Let rest for 5 minutes before serving — this allows the layers to set so you get neat slices instead of a messy scoop.
Common Mistakes I Made (And How I Fixed Them)
- Watery casserole — I didn’t squeeze the sauerkraut dry the first time, and the dish turned soupy. Now I squeeze it firmly in a clean kitchen towel or paper towels until no more liquid comes out.
- Soggy bread topping — I skipped the toasting step once to save time. The bread cubes absorbed moisture from the layers and turned mushy. Toasting for just 5 minutes creates a barrier that keeps them crunchy.
- Burnt bread cubes — I left the casserole in the oven a few extra minutes while I set the table. The bread cubes went from golden to nearly black. Watch the topping closely during the last 5 minutes of baking.
- Underseasoned layers — I forgot the black pepper. That single ingredient adds a subtle warmth that balances the tangy dressing and sauerkraut. Don’t skip it.
- Uneven layers — I rushed through the layering and ended up with all the corned beef on one side. Spreading each component evenly ensures every serving has all the flavors.
Best Tips for Pioneer Woman Reuben Casserole Success
- Toast the bread cubes until just golden — Five minutes at 375°F is usually enough. They will continue to brown slightly during the final bake, so pulling them early prevents burning.
- Use freshly shredded Swiss cheese — Pre-shredded cheese has anti-caking powders that affect melt quality. Grating a block yourself gives you a smoother, creamier melt.
- Let the casserole rest after baking — The 5-minute rest is crucial. It allows the layers to firm up, making serving much easier and preventing a sloppy plate.
- Drain the sauerkraut thoroughly — This is the number one tip for avoiding a watery casserole. Use your hands or a potato ricer to squeeze out as much liquid as possible.
- Cut the corned beef into even pieces — Uniform 1-inch pieces cook evenly and distribute nicely throughout the casserole. Larger chunks can be chewy, and tiny pieces disappear.
- Don’t overbake — Once the edges are bubbly and the bread cubes are deep golden brown, pull it out. Overbaking dries out the corned beef and makes the cheese tough.
- Serve with a side of extra dressing — Some people love a little more tangy dressing drizzled on top. Offer a small bowl of Russian or Thousand Island alongside the casserole.
Best Ingredient Swaps for Pioneer Woman Reuben Casserole
- Replace Swiss with Gruyère — The recipe notes recommend substituting half the Swiss with Gruyère for extra richness. Gruyère melts even creamier and adds a slightly nutty, earthy flavor.
- Use Thousand Island dressing — If you don’t have Russian dressing on hand, Thousand Island is a perfect swap. It’s sweeter and milder, but still provides that classic Reuben tang.
- Substitute deli corned beef with leftover roast beef — It won’t taste exactly the same, but thinly sliced roast beef works in a pinch. The texture will be less tender, so slice it against the grain.
- Try rye bread with seeds — Caraway seeds in the rye bread add an extra layer of traditional Reuben flavor. The seeds also stay crunchy on top.
- Swap sauerkraut for coleslaw mix — For a milder, slightly sweeter version, use a bagged coleslaw mix (drained) instead of sauerkraut. This turns the dish into more of a “Reuben-inspired” casserole.
Delicious Variations to Try
- Reuben Dip Casserole — Omit the top bread cube layer and mix all ingredients together with extra dressing and cheese. Bake until bubbly and serve with rye crackers or toasted baguette slices for dipping.
- Pastrami Swap — Replace corned beef with thick-sliced pastrami for a peppery, spicier twist. Pastrami’s bold flavor pairs beautifully with the other ingredients.
- Low-Carb Reuben Casserole — Skip the rye bread cubes entirely and top the casserole with crushed pork rinds mixed with a little melted butter. It bakes up crunchy and satisfying without the carbs.
- Reuben Breakfast Bake — Add six beaten eggs mixed with ¼ cup milk over the layered ingredients before adding the bread cubes. Bake as directed, and you have a hearty breakfast or brunch dish.
- Spicy Reuben — Stir 1-2 tablespoons of sriracha or chipotle hot sauce into the Russian dressing before layering. The heat cuts through the richness of the cheese and corned beef.
- Individual Reuben Casseroles — Assemble the layers in 4 small ramekins (about 1-cup capacity). Reduce baking time to 15-18 minutes. Great for portion control or dinner parties.
How to Store Leftovers Properly
- Use an airtight container — Transfer any leftover casserole to a container with a tight-fitting lid. It will keep in the refrigerator for up to 4 days.
- Keep the topping separate if possible — The bread cubes lose their crunch when stored with the moist layers. If you have extra room, store the toasted bread cubes in a separate paper bag or container and add them just before reheating.
- Freeze for up to 2 months — Assemble the casserole completely but do not bake. Cover tightly with foil and freeze. When ready to serve, bake from frozen at 375°F for about 40 minutes, then uncover and bake an additional 10 minutes to crisp the top.
How to Reheat Pioneer Woman Reuben Casserole
Reheating this casserole requires a little care to preserve the texture of the bread topping and prevent the layers from drying out. Here are three methods that work.
- Oven method (best for texture) — Preheat to 350°F. Place leftover casserole in an oven-safe dish and cover with foil. Bake for 10-15 minutes, then remove foil and bake 5 more minutes to re-crisp the bread cubes.
- Microwave method (fastest) — Place a single serving on a microwave-safe plate and heat on medium power for 1-2 minutes. The topping will soften, so if crunch matters, top with fresh toasted rye cubes afterward.
- Air fryer method (crispiest) — Set the air fryer to 350°F. Place a portion of casserole in an air fryer-safe dish and heat for 5-7 minutes. The circulating air restores the crunch to the bread cubes beautifully.

FAQs
Can I freeze Pioneer Woman Reuben Casserole?
Yes, you can freeze it unbaked or fully baked. For unbaked, assemble the casserole, wrap tightly with foil, and freeze for up to 2 months. Bake directly from frozen at 375°F for about 40 minutes uncovered, then remove foil and bake 10 more minutes to crisp the top.
What’s the best way to drain sauerkraut for this recipe?
Drain the can in a colander, then transfer the sauerkraut to a clean kitchen towel or several layers of paper towels. Gather the edges and squeeze firmly until no more liquid comes out. This step is crucial for avoiding a watery casserole.
Can I use Thousand Island dressing instead of Russian dressing?
Absolutely. Thousand Island is a bit sweeter and less spicy, but it works perfectly in this casserole. Many people actually prefer its milder flavor. The recipe gives it as an option.
How do I prevent the rye bread cubes from getting soggy?
Pre-toast the cubes for 5 minutes in butter before adding them to the casserole. This creates a crisp outer layer that resists moisture from the filling. Also, avoid over-saturating the casserole with dressing — the recipe’s ½ cup is enough.
Is this Pioneer Woman Reuben Casserole gluten-free?
Not as written because rye bread contains gluten. To make it gluten-free, use gluten-free rye-style bread (available at some specialty stores) or gluten-free sandwich bread. Also, check the label on your Russian dressing and corned beef to ensure they are gf-friendly.
