 Ingredients

Here’s everything you’ll need to recreate this deli-classic soup:

  • 2 tbsp unsalted butter – for sautéing and richness.

  • 1 medium onion, finely chopped – adds a sweet depth to balance sauerkraut.

  • 2 cloves garlic, minced – savory base flavor.

  • 2 cups corned beef, chopped or shredded – leftover corned beef is perfect here.

  • 2 cups sauerkraut, drained – tangy, briny, and the soul of a Reuben.

  • 1 tsp caraway seeds (optional) – mimics the flavor of rye bread.

  • 4 cups beef broth – forms the soup base.

  • 2 tbsp flour (or cornstarch slurry for gluten-free option) – for thickening.

  • 1 cup heavy cream – creamy richness.

  • 1 cup whole milk – balances heaviness while keeping it smooth.

  • 1 cup Swiss cheese, shredded – melty, nutty flavor that makes it indulgent.

  • Salt and black pepper, to taste

  • Fresh parsley, chopped – for garnish.

  • Rye bread croutons (optional) – to mimic the Reuben sandwich bread.

 Step-by-Step Instructions

Step 1: Sauté Aromatics

  • In a large soup pot, melt the butter over medium heat.

  • Add the onion and garlic, cooking for 3–4 minutes until softened and fragrant.

    • Tip: Don’t rush this step; sautéing builds the flavor foundation.

Step 2: Add the Meat & Sauerkraut

  • Stir in the corned beef, sauerkraut, and caraway seeds (if using).

  • Cook for 2–3 minutes to let the flavors meld.

    • Tip: Drain and squeeze sauerkraut well to avoid excess liquid.

Step 3: Build the Base

  • Sprinkle flour over the mixture and stir to coat.

  • Slowly whisk in the beef broth until smooth.

  • Bring to a gentle boil, then reduce heat and simmer for 10 minutes.

Step 4: Make it Creamy

  • Stir in heavy cream and milk.

  • Simmer gently for 5–7 minutes, but avoid boiling (to prevent curdling).

Step 5: Cheesy Finish

  • Stir in the Swiss cheese until melted and silky.

  • Season with salt and black pepper to taste.

Step 6: Serve & Garnish

  • Ladle into bowls.

  • Top with rye bread croutons and a sprinkle of fresh parsley.

  • Optional: drizzle with a little Thousand Island dressing for authentic Reuben flavor.

 Tips for the Perfect Creamy Reuben Soup

  1. Control the saltiness – Corned beef and sauerkraut are salty, so taste before adding extra salt.

  2. Thicker soup – Add an extra tablespoon of flour, or stir in diced potatoes.

  3. Lighter soup – Replace heavy cream with half-and-half or evaporated milk.

  4. Flavor boost – Add a spoonful of Dijon mustard or Thousand Island dressing to the broth.

  5. Make-ahead friendly – Cook and store in the fridge up to 3 days. Reheat gently to avoid curdling.

  6. Texture tip – For a smoother soup, blend half the mixture before adding cheese.

 Serving Suggestions

Because Creamy Reuben Soup is rich and flavorful, it pairs best with lighter or acidic sides:

  • Fresh green salad with vinaigrette.

  • Cold dill pickles – the classic Reuben sidekick.

  • Rye bread croutons or a slice of rye toast for dipping.

  • Crisp drinks like lager, pilsner, or a glass of white wine (Sauvignon Blanc works beautifully).

For a heartier meal, serve alongside roasted potatoes or a charcuterie board with cheeses and pickled vegetables.

 Variations & Adaptations

  • Gluten-free: Use cornstarch slurry instead of flour, and swap rye croutons for gluten-free bread.

  • Low-carb/keto: Skip flour and bread; add more cream and cheese for richness.

  • Vegetarian: Replace corned beef with mushrooms or smoked tempeh, and use veggie broth.

  • Spicy twist: Add diced jalapeños or a dash of hot sauce for heat.

  • Irish-style: Use leftover St. Patrick’s Day corned beef with Guinness broth for extra depth.

 The Story Behind Reuben Soup

The Reuben sandwich itself has debated origins—some say it was invented in Omaha, Nebraska by Reuben Kulakofsky, while others claim New York deli owner Arnold Reuben was responsible. Regardless of its true birthplace, the sandwich became a staple in American delis by the mid-20th century.

The transformation into soup form likely began with creative home cooks and delis looking to repurpose leftover corned beef and sauerkraut. Cream-based soups are a natural fit for cheese, and with rye bread turned into croutons, it became a complete bowl mirroring the sandwich.

Today, Creamy Reuben Soup shows up at food festivals, pubs, and home kitchens, celebrated as both inventive and nostalgic.
