Creamy Reuben Soup

Creamy Reuben Soup is one of those recipes that turns a cold evening into something worth looking forward to. I started making this after St. Patrick’s Day when I had a chunk of leftover corned beef sitting in the fridge and no real plan for it. One pot later, this soup became a regular on our dinner rotation. Every spoonful hits with that familiar, bold Reuben flavor you love, but in a rich, velvety broth that warms you from the inside out.

The first time I made it, I honestly was not sure it would work. I tossed the corned beef in with sauerkraut, poured in some broth, and crossed my fingers. What came together in that pot was something far better than I expected. This creamy Reuben soup is hearty, deeply satisfying, and surprisingly simple to pull off any night of the week. If you are a fan of that classic deli sandwich, this bowl is going to feel like home.

What You Will Need to Make This Hearty Reuben Soup

I always prep and measure every ingredient before I start cooking this one. The cheese step especially benefits from being ready to go before the pot gets hot. Pro tip: shred your Swiss cheese fresh from a block rather than buying it pre-shredded for the smoothest, creamiest results possible.

• 1 tablespoon butter
• 1 medium yellow onion, chopped
• 2 cloves garlic, minced
• 1/4 cup all-purpose flour
• 4 cups beef broth (dark beef broth adds a richer, deeper flavor)
• 1 cup sauerkraut, drained and rinsed well (rinsing reduces excess saltiness and sourness)
• 8 ounces corned beef, chopped or diced (leftover holiday corned beef works perfectly here)
• 1 cup heavy cream
• 1.5 cups Swiss cheese, freshly shredded from a block
• 1 tablespoon caraway seeds
• 1/2 teaspoon Dijon mustard
• Salt and freshly ground black pepper to taste
• 4 slices rye bread, toasted and cut into croutons for garnish

Personal tip: If you are using deli corned beef instead of leftovers, choose a thick-cut, high-quality brand. Thin deli slices can get mushy in the soup and lose their texture during simmering. This small choice makes a noticeable difference in your creamy Reuben soup.

Step-by-Step Guide to Making Creamy Reuben Soup at Home

I prefer reading through every step before starting any soup recipe, and this one is no different. The two most important things to remember here are whisking the broth in slowly and keeping the heat low once the cream and cheese go in. Rush either of those and the texture suffers.

Step 1: Melt the butter in a large pot or Dutch oven over medium heat. Add the chopped onion and cook for 5 to 6 minutes, stirring occasionally, until softened and translucent. The onion should look glossy with no raw bite remaining.

Step 2: Stir in the minced garlic and cook for 1 minute until fragrant. Watch it carefully here. Garlic that browns turns bitter and will affect the overall flavor of the soup.

Step 3: Sprinkle the flour evenly over the onion and garlic mixture. Stir constantly for about 1 minute. The mixture will look thick and paste-like. That is correct. This step cooks out the raw flour taste and builds the base for your creamy Reuben soup.

Step 4: Gradually pour in the beef broth while whisking continuously. Add the broth slowly, especially at the start, to prevent lumps from forming. Once all the broth is in and the base looks smooth, bring the soup to a gentle simmer.

Step 5: Stir in the rinsed sauerkraut, chopped corned beef, and caraway seeds. Reduce the heat to medium-low, cover the pot, and let everything simmer together for 15 to 20 minutes. This is when the flavors fully develop and the sauerkraut softens into the broth.

Step 6: Reduce the heat to low. Stir in the heavy cream, shredded Swiss cheese, and Dijon mustard. Keep stirring gently until the cheese is completely melted and the soup looks smooth and creamy. Do not let it boil at this stage. Boiling after the dairy is added can cause the cheese to separate and leave the soup with a grainy texture.

Step 7: Remove the pot from the heat. Taste and season with salt and pepper. Go easy on the salt at first since the corned beef and beef broth are both naturally salty.

Step 8: Ladle into bowls and top with toasted rye croutons. Serve immediately while the soup is hot and the croutons are still crisp.

Best Ways to Serve Your Creamy Reuben Soup

This soup pairs best with sides that offer brightness, crunch, or contrast to its rich, cheesy base. Here are some pairings that work well with creamy Reuben soup:

Dill pickles: The sharp acidity cuts right through the richness of the cream and cheese, refreshing your palate between spoonfuls.

Simple green salad: A lightly dressed salad with a tangy vinaigrette brings freshness and balance to an otherwise hearty meal.

Extra rye croutons on the side: Make a double batch and serve them alongside the soup for dipping. They soak up the broth beautifully.

Sour cream dollop on top: A small swirl stirred in at the table adds a cool, tangy note that mirrors the sauerkraut flavor already in the bowl.

A side of pickled vegetables: Pickled red onions or pickled beets add color, crunch, and a vinegary pop that works great with this creamy Reuben soup recipe.

Simple Storage and Reheating Tips for Creamy Reuben Soup

Leftover creamy Reuben soup keeps well and the flavor actually deepens overnight as everything continues to meld together. Let the soup cool completely before transferring it to an airtight container. Store in the refrigerator for up to 3 days.

To reheat, warm it gently on the stovetop over low heat, stirring occasionally. Avoid bringing it to a boil during reheating. If the soup has thickened in the fridge, stir in a splash of beef broth or a small pour of cream to loosen it back to the right consistency.

I recommend freezing individual portions in freezer-safe containers for up to 2 months. The cream and cheese may shift in texture slightly after thawing, but reheating slowly over low heat while stirring steadily will bring the soup back together. Pro tip: freeze before adding the cream and cheese if you plan to make a big batch ahead of time. Add the dairy fresh when reheating for the best texture.
