Key Ingredients for Your Baked Reuben Casserole

For the best Baked Reuben Casserole, you’ll need a few basic ingredients. Each one plays a crucial role in delivering that classic Reuben taste, with the added bonus of being easy to layer and bake.

Casserole
6–7 cups rye bread, cut into 1½-inch cubes
1 lb (450 g) corned beef, chopped or sliced
2 cups sauerkraut, well drained
2½ cups Swiss cheese, shredded
3 large eggs
1½ cups milk or half-and-half
¾ cup Thousand Island dressing
2 tbsp melted butter
½ tsp black pepper
½ tsp garlic powder
½ tsp onion powder
Optional Toppings
Extra shredded Swiss cheese
Chopped fresh parsley or dried herbs

Key Points to Remember:

  • Rye bread is traditional for this recipe because it complements the tanginess of the sauerkraut and the richness of the dressing, but feel free to experiment with sourdough or pumpernickel if you prefer.
  • Corned beef: This is the star of the dish. Using shredded corned beef gives the casserole that signature Reuben flavor, but if you’re short on time, you can use deli corned beef instead.
  • Swiss cheese: You can’t have a Reuben without Swiss cheese! Its nutty, slightly sweet flavor pairs perfectly with the other ingredients.
  • Sauerkraut: The tangy sauerkraut provides a much-needed burst of acidity to balance the richness of the cheese and beef.

    Tips and Tricks for the Perfect Baked Reuben Casserole

    Creating the perfect Baked Reuben Casserole is easy once you’ve mastered the basic steps. However, there are a few tips and tricks that can help take your casserole to the next level.

    1. Use Fresh Ingredients for the Best Taste

    While it’s tempting to grab pre-sliced corned beef and store-bought sauerkraut, fresh ingredients make all the difference. Freshly shredded cheese and corned beef from the deli will give your casserole a more flavorful and authentic taste.

    2. Experiment with Different Breads

    Rye bread is classic, but if you’re feeling adventurous, try swapping it for sourdough, pumpernickel, or even a whole-grain bread for a healthier option.

    3. Add Extra Crunch

    If you love a crispy topping, add extra Swiss cheese or even some breadcrumbs on top of the casserole for the last 10 minutes of baking. This will give it an irresistible golden, crunchy finish.

    4. Customize the Dressing

    While Thousand Island dressing is the traditional choice, feel free to experiment with other options. Russian dressing or even a tangy mustard sauce can add an interesting twist to the casserole.

    5. Make It Ahead of Time

    One of the best things about casseroles is how easy they are to prepare in advance. Assemble the casserole the night before and store it in the fridge. Then, bake it the next day when you’re ready to eat.
