Pastrami-Reuben Casserole: A Comfort Food Classic Reimagined

The scent of a perfectly grilled Reuben sandwich is practically a Proustian madeleine for me, instantly transporting me back to my grandfather’s deli. I remember sitting on those red vinyl booths, the aroma of cured meats and tangy sauerkraut filling the air, as he carefully assembled towering Reubens for his loyal customers. The combination of savory pastrami, sharp Swiss cheese, creamy Thousand Island dressing, and that distinctive sauerkraut tang, all nestled between slices of rye bread…pure heaven. This Pastrami-Reuben Casserole captures all that nostalgic goodness in an easy-to-make, shareable format.

Recipe Overview

• Prep Time: 25 minutes
• Cook Time: 33 minutes
• Total Time: 58 minutes
• Servings: 6
• Yield: 1 casserole
• Dietary Type: Not Gluten-Free

Ingredients

• 8 slices dark pumpernickel bread (or use as much bread slices as needed to cover the bottom of the baking dish) or 8 slices rye bread (or use as much bread slices as needed to cover the bottom of the baking dish)
• Soft butter
• 1 (16 ounce) can sauerkraut, well drained (you may rinse if desired)
• 1 lb pastrami (cut into strips, can use more or less than) or 1 lb corned beef (cut into strips, can use more or less than)
• 2 cups thousand island dressing (see my Kittencal’s Thousand Island Dressing)
• 2 cups shredded swiss cheese (can use more) or 2 cups mozzarella cheese (can use more)

Equipment Needed

• 13 x 9-inch baking dish
• Baking sheet
• Knife
• Cutting board

Instructions

1. Preheat your oven to 400°F (200°C).

2. Grease a 13 x 9-inch baking dish generously. This will prevent the casserole from sticking and ensure easy cleanup.

3. Lightly butter both sides of each bread slice with the soft butter. This step is crucial for achieving that signature golden-brown crust and preventing the bread from becoming soggy.

4. Slice the buttered bread into approximately 1 1/2-inch cubes. The size doesn’t need to be exact, but aim for relatively uniform pieces for even toasting.

5. Place the bread cubes on a baking sheet in a single layer.

6. Bake the bread cubes in the preheated oven until they are semi-crisp, but not hard or brown. This usually takes about 8-10 minutes. Keep a close eye on them to prevent burning. This step is important! Toasting the bread prevents it from absorbing too much moisture from the other ingredients and turning mushy.

7. Spread the toasted bread cubes evenly in the prepared baking dish, ensuring they cover the entire bottom surface. These cubes act as the foundation for the entire casserole.

8. Evenly distribute the well-drained sauerkraut over the bread cubes. Make sure to press the sauerkraut in a sieve or with paper towels to remove as much excess liquid as possible. Excess moisture can make the casserole soggy. Rinsing the sauerkraut is optional if you find it too tangy.

9. Layer the pastrami strips (or corned beef) evenly over the sauerkraut. Feel free to use more or less meat according to your preference.

10. Pour the Thousand Island dressing completely over the top of the pastrami layer. Use enough dressing to generously coat the meat and sauerkraut. Don’t be shy! The dressing is key to the Reuben flavor. If you feel two cups aren’t enough, use more.

11. Cover the baking dish tightly with aluminum foil.

12. Bake the casserole on the bottom oven rack at 400°F (200°C) for 20-25 minutes. The foil helps to steam the ingredients and meld the flavors together.

13. Remove the foil from the baking dish.

14. Sprinkle the shredded Swiss cheese (or mozzarella cheese) evenly over the top of the casserole. Again, feel free to add more cheese if desired.

15. Return the casserole to the oven and continue baking uncovered for another 6-8 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Watch carefully to avoid burning the cheese.

Expert Tips & Tricks

• Bread Choice: Dark pumpernickel or rye bread are traditional choices, but feel free to experiment with other hearty breads like sourdough. Just make sure the bread is sturdy enough to hold up to the moisture of the casserole.
• Sauerkraut Prep: Draining the sauerkraut thoroughly is essential to prevent a soggy casserole. Squeeze it in a clean kitchen towel to remove as much excess liquid as possible.
• Homemade Dressing: For the best flavor, consider using homemade Thousand Island dressing. The difference in taste is remarkable.
• Make-Ahead: You can assemble the casserole a day ahead of time, cover it tightly with foil, and store it in the refrigerator. Add a few extra minutes to the baking time when you’re ready to cook it.
• Preventing Soggy Bread: If you are skipping the toasting step (though highly recommended!), squeeze the sauerkraut with extra force and consider adding a thin layer of grated Parmesan cheese between the bread and sauerkraut to act as a moisture barrier.

Serving & Storage Suggestions

Serve the Pastrami-Reuben Casserole warm, straight from the oven. It’s delicious on its own, but you can also serve it with a side of pickles, coleslaw, or a simple green salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, bake in a preheated oven at 350°F (175°C) until heated through, or microwave in individual portions. Reheating in the oven will help maintain the crispy bread texture. Freezing is not recommended, as the texture of the bread and sauerkraut may change.
