How to Make Creamy Reuben Soup Recipe

Step 1: Build Your Flavor Base

Start by melting the butter in a large pot over medium heat. As it melts, toss in your finely chopped onion and cook it gently until it becomes translucent—this usually takes about 5 minutes and releases the onion’s natural sweetness. Then add the minced garlic, letting it cook for another minute just to awaken its aroma, but be careful not to let it brown or burn.

Step 2: Create the Roux and Thicken

Sprinkle the flour evenly over the softened onions and garlic, stirring constantly. This step forms a roux, which is essential for thickening the soup into a creamy, velvety consistency. Cook for about 2 minutes, ensuring the flour cooks out and you don’t lose that fresh floury taste.

Step 3: Add the Broth and Simmer

Slowly whisk in the beef broth to avoid any lumps, blending until smooth. Bring the mixture up to a simmer and let it cook for around 5 minutes. This gives the broth a chance to thicken just enough and marry with the roux, setting a luscious foundation for the soup.

Step 4: Stir in Cream, Corned Beef, and Sauerkraut

Lower the heat to gentle and blend in the half-and-half, chopped cooked corned beef, and chopped sauerkraut. If you’re a fan of the subtle licorice notes, sprinkle in the caraway seeds here. Allow the soup to simmer gently for 10 to 15 minutes, stirring occasionally to meld the flavors together without boiling.

Step 5: Finish with Swiss Cheese

Finally, stir in the shredded Swiss cheese, letting it melt smoothly into the soup. This finishing touch gives the soup that irresistible creamy texture and cheesy pull that makes this Creamy Reuben Soup Recipe truly memorable. Taste and season with salt and black pepper to your preference.

How to Serve Creamy Reuben Soup Recipe

Garnishes

A bowl of Creamy Reuben Soup is always improved with the right garnishes. Top your soup with crunchy rye bread croutons or a warm slice of toasted rye bread to add texture and a toasty aroma that pairs beautifully with the tangy sauerkraut and creamy broth. For a pop of color and freshness, sprinkle some finely chopped fresh parsley or chives.

Side Dishes

This soup stands comfortably on its own but can easily be accompanied by a simple green salad dressed with a light vinaigrette to cut through the richness. Pickles or a side of coleslaw also complement the Reuben flavors perfectly, echoing that deli feel and balancing the meal.

Creative Ways to Present

If you’re serving this to guests or want to add some flair, consider hollowing out small rye bread bowls as edible vessels. Not only does this amp up the presentation, but those bread bowls add texture and soak up the delicious creamy broth. You can also serve with a small platter of deli meats and cheeses alongside to create an interactive Reuben-inspired tasting experience.

Make Ahead and Storage

Storing Leftovers

If you have any leftover Creamy Reuben Soup Recipe, simply transfer it to an airtight container and store it in the refrigerator. It will stay fresh for about 3 to 4 days. The flavors actually deepen after resting and the soup reheats beautifully, making it an ideal make-ahead meal.

Freezing

You can freeze this soup for longer storage, but keep in mind that the creamy half-and-half may separate slightly after thawing. To freeze properly, cool the soup completely, then pour it into freezer-safe containers or bags, leaving some space for expansion. It will keep well for up to 2 months.

Reheating

When reheating your Creamy Reuben Soup Recipe, warm it over low heat on the stovetop, stirring regularly to recombine the ingredients. If the texture seems a bit grainy or separated, whisk in a splash of fresh half-and-half or milk to restore that silky creaminess. Avoid boiling as it can cause further separation.

FAQs

Can I use pastrami instead of corned beef in this Creamy Reuben Soup Recipe?

Absolutely! Pastrami makes a fantastic substitute, offering a slightly smoky twist on the classic flavor while maintaining that tender, savory meatiness. Just chop it similarly and add it along with the corned beef in the simmering step.

Is this soup gluten-free?

The original recipe uses all-purpose flour and rye bread croutons, which contain gluten. To make it gluten-free, swap the flour for a gluten-free blend and serve with gluten-free bread or croutons. The flavor remains just as rich and satisfying.

Can I make this soup vegetarian?

To adapt the Creamy Reuben Soup Recipe for vegetarians, use vegetable broth instead of beef broth and substitute the corned beef with a plant-based alternative. You might also want to skip the caraway seeds if you’re aiming for a milder flavor. The cheesy creaminess will still shine through nicely.

What’s the best way to get a smoother texture?

For an extra smooth and silky soup, consider using an immersion blender before adding the Swiss cheese. This step purees the base, blending the onions and broth evenly, giving you a velvety soup that’s dreamy in every spoonful.

How spicy is this soup?

This soup is generally mild with a tangy punch from the sauerkraut. You can add a pinch of crushed red pepper flakes or a dash of hot sauce for heat if you like, but the traditional recipe keeps things comforting and gentle.
