Ingredients & Their Purpose

Here’s a breakdown of each ingredient and why it’s essential to achieving the perfect Creamy Reuben Soup:

• 2 tablespoons butter – foundation for the flavor base, helping to sauté vegetables and enhance richness.
• 1 small onion, finely chopped – adds sweetness and depth, balancing the tang of the sauerkraut.
• 2 cloves garlic, minced – infuses the soup with a warm, aromatic undertone.
• 3 tablespoons all-purpose flour – thickens the soup into a creamy, velvety consistency.
• 4 cups beef broth – provides a savory backbone and rich flavor reminiscent of deli-style broths.
• 1 cup milk (whole or 2%) – contributes creaminess and body to the soup.
• 1 cup heavy cream – intensifies the luxurious texture, making it smooth and indulgent.
• 1 ½ cups chopped corned beef – the star protein, delivering the classic Reuben flavor.
• 1 cup sauerkraut, drained and chopped – provides tanginess and acidity, cutting through the richness of the soup.
• 1 ½ cups shredded Swiss cheese – adds melty, nutty goodness, creating the signature cheesy layer of flavor.
• 1 teaspoon Dijon mustard – gives a slightly spicy, tangy punch that complements the corned beef.
• 1 teaspoon Worcestershire sauce – boosts umami depth, enhancing the savory notes of the soup.
• Salt and freshly ground black pepper, to taste – essential for balancing flavors.
• Optional garnish: chopped fresh parsley, extra shredded Swiss, or rye croutons – adds visual appeal, freshness, and crunch.

Step-by-Step Instructions

Follow these step-by-step directions to create a soup that’s rich, creamy, and full of flavor:

Step 1: Prepare the Flavor Base

1. In a large soup pot or Dutch oven, melt the butter over medium heat.
2. Add the chopped onion and sauté for 3–4 minutes, until translucent and slightly golden.
3. Stir in the garlic and cook for an additional 30 seconds, just until fragrant.

Pro Tip: Do not let the garlic brown, as it can turn bitter and overpower the soup.

Step 2: Create the Roux

1. Sprinkle the all-purpose flour over the onions and garlic.
2. Stir continuously for 1–2 minutes to form a light roux, which will thicken the soup later.

Pro Tip: Cooking the flour briefly removes the raw taste and ensures a smooth, lump-free soup.

Step 3: Build the Soup Base

1. Slowly pour in the beef broth, whisking constantly to prevent lumps.
2. Add milk and bring the mixture to a gentle simmer.
3. Stir in the heavy cream, creating a rich, velvety base.

Pro Tip: Keep the heat low to prevent the dairy from curdling.

Step 4: Add the Star Ingredients

1. Gently fold in the chopped corned beef and sauerkraut.
2. Stir in Dijon mustard and Worcestershire sauce, blending the flavors evenly.
3. Simmer for 10–15 minutes on low heat to allow the savory, tangy, and cheesy flavors to meld beautifully.

Step 5: Melt in the Swiss Cheese

1. Gradually add the shredded Swiss cheese, stirring continuously to achieve a silky, cheesy consistency.
2. Taste the soup and adjust salt and pepper as needed.

Pro Tip: Use freshly shredded Swiss cheese for better meltability and flavor compared to pre-shredded cheese.

Step 6: Serve & Garnish

1. Ladle the soup into warm bowls.
2. Garnish with fresh parsley, extra Swiss cheese, or crispy rye croutons.

Serving Suggestion: Pair with a crusty rye bread or grilled rye sandwich for a complete deli-style experience.
