Ingredients Breakdown

Creating the perfect Reuben Soup begins with understanding the role of each ingredient in developing its signature taste and texture. This creamy, savory dish is built from a balanced mix of proteins, vegetables, dairy, and seasonings, each contributing to its distinctive deli-style flavor. Let’s explore what makes each element essential.

• Butter: Used as the base fat for sautéing, butter adds a subtle richness that complements the other bold flavors.
• Onion and Garlic: These aromatic ingredients form the flavor foundation. Onions add sweetness while garlic introduces depth.
• Chicken Ham or Corned Beef: The main protein in this soup can vary. While corned beef is traditional (learn more about it here), chicken ham offers a lighter alternative. Both options infuse the broth with a hearty, meaty essence.
• Cabbage or Sauerkraut: These bring a tangy and slightly crunchy texture. Sauerkraut adds a fermented bite (explained in detail at Sauerkraut), while shredded cabbage is milder and better suited for those who prefer less acidity.
• Potato: Diced russet potatoes thicken the soup naturally and enhance its heartiness, making it filling enough for a full meal.
• Chicken Broth: Provides a savory, umami-rich liquid base that ties the ingredients together.
• Milk and Heavy Cream: The combination of whole milk and heavy cream gives the soup its signature creaminess without being too heavy. This dairy blend also allows the cheese to melt evenly.
• Dijon Mustard: Adds a punch of sharpness and elevates the soup’s flavor complexity. More about this versatile ingredient can be found here.
• Swiss Cheese: This is the key to achieving the Reuben taste. It melts smoothly into the broth and contributes a nutty, creamy element. If you want to explore its varieties and uses, visit Swiss Cheese.
• Salt and Black Pepper: Used to enhance and balance flavors. A little goes a long way, especially if sauerkraut or cured meats are heavily salted.
• Rye Croutons or Toasted Rye Bread: Garnish with rye bread to mimic the sandwich aspect. The crunch provides textural contrast.
• Fresh Parsley: Adds color and a fresh finish to balance the richness.

• Swap potatoes with cauliflower for a low-carb alternative.

With these ingredients understood and prepped, you’re ready to bring together a bowl of creamy Reuben comfort.

How to Make Reuben Soup on the Stovetop

Making Reuben Soup on the stovetop is a straightforward process that delivers maximum flavor in minimal time. With just a few steps and simple ingredients, you can transform deli favorites into a rich, satisfying soup that’s perfect for lunch or dinner. Here’s how to do it right, while ensuring a smooth, creamy texture and bold taste in every bite.

Step-by-Step Instructions

1. Sauté the Aromatics
   • In a large soup pot or Dutch oven, melt 2 tablespoons of butter over medium heat.
   • Add 1 small diced onion and cook until it becomes translucent and soft, about 4–5 minutes.
   • Stir in 2 cloves of minced garlic, cooking for another minute until fragrant. This base builds the depth of flavor essential to any hearty soup.
2. Add the Meat
   • Stir in 2 cups of chopped chicken ham or corned beef. Sauté until the meat starts to brown slightly, enhancing its savory profile.
   • For a richer flavor, you can use traditional corned beef—learn about its origins and preparation in this corned beef guide.
3. Incorporate the Vegetables
   • Add 1½ cups of shredded green cabbage or well-drained sauerkraut (refer to Sauerkraut to understand the fermentation process).
   • Stir in 1 peeled and diced russet potato.
   • Mix everything well, allowing the ingredients to absorb the aromatic base.
4. Add the Liquid
   • Pour in 2 cups of chicken broth and bring the mixture to a gentle boil.
   • Once boiling, reduce the heat to low, cover the pot, and let it simmer for 15–20 minutes or until the potatoes are fork-tender.
5. Stir in the Dairy
   • After the vegetables are tender, reduce the heat to very low and add 1 cup of whole milk and 1 cup of heavy cream.
   • Stir in 1 tablespoon of Dijon mustard for a sharp, tangy note (discover more about Dijon here).
   • Allow the soup to warm slowly. Avoid boiling at this stage to prevent the dairy from curdling.
6. Melt the Cheese
   • Gradually add 1 cup of shredded Swiss cheese, stirring constantly until it melts into the broth.
   • Avoid pre-shredded cheese, as it may contain anti-caking agents that hinder smooth melting. Explore the role of Swiss cheese in traditional recipes.
7. Final Seasoning
   • Season with salt and black pepper to taste.
   • Be cautious with salt if using sauerkraut or cured meats, which may already be quite salty.
8. Garnish and Serve
   • Ladle the soup into bowls and top with toasted rye croutons or pieces of rye bread (learn more).
   • Sprinkle with freshly chopped parsley for a touch of brightness and color.

Tips for Success

• Avoid Boiling After Adding Dairy: To maintain a silky texture, keep the heat low once the milk and cream are added.
• Drain Sauerkraut Well: Too much brine can overpower the soup’s balance.
• Use Freshly Grated Cheese: For the smoothest results, shred cheese from a block.
