Ingredients for Your Reuben Casserole

Here’s what you’ll need to create this masterpiece. Don’t worry, most of these are pantry staples!

• Sauerkraut: 1 can (14.5 ounces), drained well. Draining the sauerkraut is essential to prevent a soggy casserole.
• Swiss Cheese: 3 1/2 cups shredded. The nutty, slightly tangy flavor of Swiss cheese is key to that classic Reuben taste.
• Russian Dressing: 6 tbsp. Adds that signature tang and sweetness. Thousand Island dressing works as a substitute if you don’t have Russian dressing on hand.
• Eggs: 3 large. These act as a binder for the custard, creating a creamy texture.
• Pastrami: 1 1/3 lb. While corned beef is traditional, I love using pastrami for its smoky flavor.
• Rye Bread: 7 slices. The foundation of our casserole.
• Milk: 1 1/2 cups. Adds moisture and richness to the custard.
• Yellow Mustard: 4 tbsp. Provides a tangy kick that complements the other flavors.
• Pickles: 1 cup, chopped. Dill pickles add a delightful crunch and tangy contrast.
• Caraway Seeds: 2 tsp. These little seeds are what give rye bread its distinctive flavor.

How to Make Easy Reuben Casserole: Step-by-Step

Let’s walk through the steps together. Don’t worry, it’s easier than you think!

1. Preheat and Prep: Preheat your oven to 350°F (175°C) to ensure it’s hot and ready once you assemble the casserole. Lightly grease a 9×13-inch baking dish with non-stick cooking spray.
2. Prepare the Rye Bread Base: Take 4 slices of rye bread and cut them into rough 2-inch cubes. Spread them out across the bottom of your prepared dish, making sure to cover the surface evenly without overcrowding. Then, take the remaining 2 slices of rye bread and pulse them in a food processor until they turn into fine breadcrumbs—these will be used as a crunchy topping at the end. Set the crumbs aside in a small bowl.
3. Layer the Ingredients: Sprinkle half of the chopped pastrami over the cubed bread layer. Then add a 14-oz can (or jar) of sauerkraut—make sure it’s been drained very well to avoid a soggy casserole. Press gently with paper towels or squeeze through a colander. Follow that with 1 cup of chopped dill pickles for tangy crunch and 1 teaspoon of caraway seeds for classic rye flavor. Gently press the layers down so they start to settle without becoming compacted.
4. Add Cheese and More Pastrami: Layer 2 cups of shredded Swiss cheese over the sauerkraut and pickle mix, spreading it to the edges so every bite gets melty cheese. Then add the remaining pastrami, making sure it’s evenly distributed. Press everything down again—this helps the custard soak in later. Top it all with the final 2 cups of shredded Swiss cheese and another teaspoon of caraway seeds for an extra burst of flavor on top.
5. Make the Custard: In a medium bowl, whisk together 1 cup of milk, 3 large eggs (beaten), ⅓ cup Russian or Thousand Island dressing, and ¼ cup yellow mustard until smooth and fully combined. This mixture is what binds the casserole together and gives it that signature creamy texture. Pour the custard mixture slowly and evenly over the entire casserole, making sure to coat all corners and edges. Use the back of a spoon or spatula to gently press the mixture into the layers so it fully absorbs into the bread.
6. Add the Crumbs and Bake: Take the reserved rye breadcrumbs and sprinkle them generously over the top of the casserole. This creates a crunchy, golden crust once baked. Cover the dish with foil to trap moisture and bake for 45 minutes. Then, remove the foil and bake for an additional 10 to 15 minutes, or until the cheese is melted, bubbling, and lightly browned on top.

Pro Tips for the Perfect Reuben Casserole

Here are a few extra tips to ensure your casserole turns out perfectly every time:

• Drain the Sauerkraut Well: This is crucial to prevent a soggy casserole. Use paper towels or a colander to remove excess moisture.
• Don’t Overcrowd the Bread Base: The bread cubes should cover the bottom of the dish without being too tightly packed. This allows the custard to soak in properly.
• Press the Layers Down Gently: This helps the ingredients meld together and prevents the casserole from falling apart when you serve it.
• Use a Good Quality Cheese: The flavor of the Swiss cheese really shines through in this recipe, so choose a good quality brand.
• Let it Rest: After baking, let the casserole rest for 10-15 minutes before slicing and serving. This allows the custard to set and the flavors to meld together even further.

Common Mistakes to Avoid

Even the best cooks make mistakes! Here are a few common pitfalls to watch out for:

• Using Too Much Liquid: Soggy casseroles are no fun! Make sure to drain the sauerkraut thoroughly and avoid adding extra liquid to the custard.
• Overbaking: Overbaking can result in a dry, tough casserole. Keep an eye on it and remove it from the oven when the cheese is melted and bubbly and the top is lightly browned.
• Skipping the Breadcrumb Topping: The breadcrumb topping adds a delightful crunch that really elevates the dish. Don’t skip it!
• Not Seasoning Properly: Taste as you go and adjust the seasoning as needed. A little extra salt and pepper can make a big difference.

Reuben Casserole Variations

Want to mix things up? Here are a few fun variations to try:

• Corned Beef Reuben Casserole: Substitute the pastrami with corned beef for a more traditional flavor.
• Spicy Reuben Casserole: Add a pinch of red pepper flakes or a dash of hot sauce to the custard for a spicy kick.
• Vegetarian Reuben Casserole: Use a plant-based corned beef substitute and vegetable broth in the custard for a vegetarian-friendly version.
• Deluxe Reuben Casserole: Add sauteed onions and peppers to the layers for extra flavor and texture.

How to Store Leftover Reuben Casserole

If you have any leftovers (which is rare!), here’s how to store them:

• In the Refrigerator: Store the casserole in an airtight container in the refrigerator for up to 3-4 days.
• To Reheat: Reheat individual portions in the microwave or bake the entire casserole in a preheated oven at 350°F (175°C) until warmed through.

Frequently Asked Questions (FAQ)

Here are some common questions about making Reuben Casserole:

• Can I assemble the casserole ahead of time?: Yes! Assemble the casserole, cover it tightly with plastic wrap, and store it in the refrigerator for up to 24 hours. Add the breadcrumb topping just before baking.
• Can I freeze Reuben Casserole?: While you can freeze it, the texture may change slightly. If freezing, wrap the casserole tightly in plastic wrap and then in foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before baking.
• Can I use a different type of cheese?: While Swiss is traditional, you can experiment with other cheeses like Gruyere or provolone.
• Can I use pre-shredded cheese?: Yes, but freshly shredded cheese melts more smoothly.
