The History and Cultural Significance of the Reuben

The Reuben sandwich is a beloved American classic, typically made with grilled rye bread, corned beef, Swiss cheese, sauerkraut, and Thousand Island or Russian dressing. Its origins are somewhat debated—some say it was created in Omaha, Nebraska, in the 1920s, while others claim it originated at a New York deli.

Regardless of its roots, the Reuben has remained a staple of American delis and diners for nearly a century. Over time, creative cooks have found new ways to enjoy its signature flavors, leading to variations like Reuben dip, Reuben casserole, and, of course, Creamy Reuben Soup.

This soup captures all the elements of the sandwich but transforms them into a warm and spoonable comfort food. The tanginess of the sauerkraut, the smokiness of the corned beef, and the melty Swiss cheese come together in a creamy, satisfying broth that will have you reaching for seconds.

Common Mistakes to Avoid When Making Creamy Reuben Soup

1. Not Draining the Sauerkraut Properly

Leaving too much brine in the sauerkraut can make the soup overly sour. Be sure to drain and rinse it briefly before adding it to the pot.

2. Overheating the Cheese

Swiss cheese can clump or turn grainy if exposed to too much heat. Always lower the heat before stirring in the cheese, and whisk continuously for a smooth and creamy consistency.

3. Using Pre-Shredded Cheese

Pre-shredded cheeses often contain anti-caking agents, preventing them from melting smoothly. Grate your own Swiss cheese for a velvety texture.

4. Skipping the Rye Bread Garnish

The toasted rye croutons or buttered rye toast are what make this soup taste like an actual Reuben sandwich. Don’t skip this step!

Try these Crusty Artisan Lettuce Salad for another way to balance out the meal.

5. Not Letting the Flavors Meld

Like many soups, Reuben Soup tastes even better the next day. If time allows, let it sit for a few hours before serving to enhance the flavors.

How to Store & Reheat Creamy Reuben Soup

One of the best things about Creamy Reuben Soup is that it can be made ahead and stored for easy meals throughout the week. The flavors meld and deepen over time, making it taste even better the next day. However, because of its dairy content, there are a few things to keep in mind when storing and reheating to maintain the best texture and flavor.

Refrigerator Storage

• Let the soup cool completely before transferring it to an airtight container.
• Store in the refrigerator for up to 4 days.
• The soup may thicken as it sits, but you can easily adjust it when reheating.

• Freeze without the cheese and cream, then add them fresh when reheating.
• Store in freezer-safe containers for up to 3 months.
• Label with the date so you don’t forget when you made it!
