Step-by-Step Instructions

1. Sauté the Aromatics

In a large soup pot, melt 2 tablespoons of butter over medium heat. Add the chopped onion and cook for about 4–5 minutes until softened and translucent. Stir occasionally to prevent browning.

Add the minced garlic and cook for another 30 seconds until fragrant.

2. Create the Base

Sprinkle in 2 tablespoons of all-purpose flour and stir continuously for 1–2 minutes. This creates a roux that will thicken the soup.

Slowly pour in 3 cups of beef broth while whisking to prevent lumps. Continue stirring until the mixture becomes smooth and begins to slightly thicken.

3. Add the Creaminess

Pour in 1 cup heavy cream and 1 cup whole milk. Stir well and allow the soup to gently simmer for about 5 minutes.

The broth will begin to develop a creamy, velvety texture.

4. Add the Signature Ingredients

Stir in:

• 1 ½ cups chopped corned beef
• 1 ½ cups drained sauerkraut
• 1 teaspoon Dijon mustard
• ½ teaspoon caraway seeds
• ¼ teaspoon black pepper

Let the soup simmer gently for about 8–10 minutes to allow the flavors to blend.

5. Melt the Cheese

Reduce the heat to low and gradually add the shredded Swiss cheese, stirring continuously until fully melted and smooth.

Taste the soup and adjust salt if needed.

6. Serve and Garnish

Ladle the hot soup into bowls and top with chopped parsley and rye bread croutons.

The crunchy rye bread adds a wonderful contrast to the creamy soup.

Tips for the Best Reuben Soup

Use Quality Corned Beef

Leftover homemade corned beef works wonderfully, but deli-style corned beef is also perfect for this recipe. Chop it finely so it blends well with the soup.

Balance the Sauerkraut

If you prefer a milder flavor, rinse the sauerkraut briefly under cold water. This removes some of the sharp acidity while keeping the signature tang.

Add Texture

Rye bread croutons or toasted rye cubes mimic the bread element of the classic sandwich and add delicious crunch.

Keep the Heat Low After Adding Cheese

High heat can cause cheese to become grainy. Always melt cheese slowly over low heat.

---

Delicious Variations

This recipe is flexible and can be customized to your taste.

Lighter Version

Replace heavy cream with an additional cup of whole milk or half-and-half.

Extra Cheesy

Add an additional ½ cup (55 grams) of Swiss cheese for an even richer texture.

Vegetable Boost

Add ½ cup diced celery and ½ cup shredded carrots when sautéing the onions.

Slow Cooker Method

Combine all ingredients except the cheese and cream in a slow cooker. Cook on low for 4–5 hours, then stir in the cream and cheese during the final 20 minutes.

What to Serve with Reuben Soup

This soup is hearty enough to stand on its own but pairs beautifully with simple sides.

Storage and Reheating Tips

Refrigeration

Store leftover soup in an airtight container in the refrigerator for up to 3 days.

Freezing

Because the soup contains dairy, freezing may slightly affect the texture. If freezing, allow the soup to cool completely and store for up to 2 months.

Reheating

Reheat gently on the stovetop over low heat, stirring frequently. Add a splash of milk if the soup becomes too thick.

Frequently Asked Questions

Can I use deli corned beef instead of homemade corned beef?

Yes, deli corned beef works perfectly for this recipe and is often the easiest option. Many people actually prefer using deli corned beef because it is already tender and thinly sliced, making it simple to chop into bite-sized pieces for the soup. When purchasing deli corned beef, ask for thicker slices so you can easily dice it into small chunks. Approximately 1 ½ cups or about 225 grams of chopped corned beef is the ideal amount for this recipe. If you happen to have leftover homemade corned beef from another meal, that works wonderfully as well and may add even more depth of flavor to the soup.

Does sauerkraut make the soup too sour?

Sauerkraut adds a signature tangy flavor, but it should not overpower the soup. The cream, milk, and melted Swiss cheese balance the acidity and create a smooth, rich flavor profile. If you prefer a milder taste, you can lightly rinse the sauerkraut under cold water before adding it to the soup. This removes some of the brine while keeping the fermented character that makes the dish unique. Another helpful tip is to add the sauerkraut gradually and taste as you go to achieve the perfect balance between creamy and tangy.

What type of cheese works best for Reuben soup?

Swiss cheese is the best choice for authentic flavor because it is traditionally used in the classic Reuben sandwich. Its mild nutty taste melts beautifully into the soup and helps create a silky texture. For best results, shred the cheese yourself instead of using pre-shredded varieties, which often contain anti-caking agents that prevent smooth melting. If Swiss cheese is unavailable, you can substitute it with mild provolone or mozzarella, though the flavor will be slightly different. The goal is to choose a cheese that melts well and complements the savory ingredients.

Can I make this soup ahead of time?

Yes, this soup can absolutely be made ahead of time, which makes it great for meal preparation or entertaining. After cooking, allow the soup to cool and store it in an airtight container in the refrigerator for up to three days. When reheating, warm it slowly on the stovetop over low heat while stirring frequently. Because the soup contains dairy and cheese, gentle reheating helps maintain a smooth texture. If the soup thickens during storage, simply add a splash of milk or broth while reheating to restore its creamy consistency.
