Ingredients

For the Soup Base

• 4 tablespoons (57g) unsalted butter
• 1 medium yellow onion, finely diced (about 1 cup/150g)
• 3 cloves garlic, minced (approximately 1 tablespoon)
• 1/3 cup (42g) all-purpose flour
• 4 cups (960ml) beef broth (low-sodium recommended)
• 2 cups (480ml) half-and-half or heavy cream
• 1 pound (454g) cooked corned beef, diced into bite-sized pieces
• 2 cups (280g) sauerkraut, drained and roughly chopped
• 2 cups (226g) shredded Swiss cheese
• 2 tablespoons (30ml) prepared Thousand Island dressing
• 1 tablespoon (15ml) Worcestershire sauce
• 1/2 teaspoon caraway seeds (optional but traditional)
• Salt and freshly ground black pepper to taste

The corned beef provides the signature savory foundation, while sauerkraut delivers that essential tangy bite. Swiss cheese melts beautifully into the broth, creating luxurious creaminess.

Pro Tips

Master the roux by cooking your butter and flour mixture for at least 2 minutes over medium heat, stirring constantly until it turns a light golden color and smells nutty. This crucial step eliminates the raw flour taste and creates the perfect thickening base for your Reuben soup recipe. Never rush this process, as a properly cooked roux makes the difference between a flour-tasting soup and a professionally smooth one.

Always add your cheese gradually while the heat is on low, stirring continuously to ensure smooth incorporation without graininess or separation. High heat causes cheese proteins to seize up, resulting in a stringy, broken texture rather than the silky consistency you’re aiming for. Shred your own Swiss cheese from a block instead of using pre-shredded varieties, which contain anti-caking agents that prevent proper melting.

Don’t skip draining and chopping your sauerkraut, as excess liquid will make your soup too thin and overwhelmingly tangy. Pat the sauerkraut dry with paper towels after draining for the best texture and balanced flavor profile in your finished dish.

Instructions

Step 1: Prepare Your Base

Melt the butter in a large heavy-bottomed pot or Dutch oven over medium heat. Add the diced onion and sauté for about 5 minutes until softened and translucent, stirring occasionally to prevent browning. The onions should smell sweet and fragrant when ready. Add the minced garlic and cook for an additional minute, stirring constantly to prevent burning, as burnt garlic will add bitter notes to your soup.

Step 2: Create the Roux

Sprinkle the flour over the butter and onion mixture, stirring immediately to combine everything into a thick paste. Cook this roux for 2-3 minutes, stirring constantly with a wooden spoon or whisk. The mixture should bubble gently and turn a light golden color while developing a slightly nutty aroma. This step builds the foundation for your soup’s creamy texture.

Step 3: Add Liquids Gradually

Slowly pour in the beef broth, about one cup at a time, whisking vigorously after each addition to prevent lumps from forming. The mixture will initially look thick and pasty but will gradually loosen as you incorporate more liquid. Once all the broth is added and smooth, stir in the half-and-half or heavy cream. Bring the mixture to a gentle simmer, then reduce heat to medium-low. Allow it to cook for 5-7 minutes, stirring occasionally, until the soup thickens enough to coat the back of a spoon.

Step 4: Incorporate Main Ingredients

Add the diced corned beef and chopped sauerkraut to the pot, stirring to distribute evenly throughout the creamy base. Pour in the Thousand Island dressing and Worcestershire sauce, which add that authentic Reuben sandwich flavor profile. If using caraway seeds, add them now for traditional rye bread notes. Let everything simmer together for 5 minutes, allowing the flavors to meld beautifully.

Step 5: Finish with Cheese

Reduce the heat to low and gradually add the shredded Swiss cheese, stirring constantly in a figure-eight motion. Add the cheese in three or four batches, making sure each addition is fully melted and incorporated before adding more. This patient approach ensures a smooth, creamy texture without any graininess. Once all the cheese has melted into silky perfection, taste and adjust seasoning with salt and black pepper as needed. Remember that corned beef and sauerkraut are both salty, so you may need very little additional salt.

Variations

For a creamy corned beef soup with lighter calories, substitute the half-and-half with whole milk and reduce the cheese to 1.5 cups, adding a tablespoon of cornstarch slurry if needed to maintain thickness. The soup will be less rich but still wonderfully satisfying.

Create a Reuben chowder style version by adding 2 cups of diced Yukon Gold potatoes along with the corned beef, simmering until tender. This heartier variation transforms the soup into a complete meal that’s even more filling.

Make it gluten-free by replacing all-purpose flour with a gluten-free flour blend or cornstarch for the roux, and serve with gluten-free bread or crackers instead of traditional rye toast points. The flavor remains authentic while accommodating dietary restrictions.

Try a turkey Reuben variation by substituting deli turkey for corned beef and using white cheddar instead of Swiss cheese for a lighter flavor profile that’s equally delicious.

Storage and Serving

Store leftover Creamy Reuben Soup in an airtight container in the refrigerator for up to 4 days. The soup may thicken upon cooling, so add a splash of beef broth or cream when reheating to restore the desired consistency. Reheat gently over medium-low heat on the stovetop, stirring frequently, or microwave in 1-minute intervals, stirring between each cycle to ensure even heating without scorching the dairy.

Freezing is not recommended for this soup because dairy-based recipes with cheese tend to separate and become grainy when thawed. If you must freeze it, do so without the cheese and add fresh shredded cheese when reheating.

Serve your soup in warm bowls topped with extra shredded Swiss cheese, a dollop of sour cream, and chopped fresh dill or parsley for color. Crusty rye bread, toasted marble rye croutons, or buttery crackers make perfect accompaniments for dipping. For an authentic presentation, serve alongside dill pickle spears and extra Thousand Island dressing on the side, just like a traditional Reuben sandwich platter.
