What Ingredients You Will Need

This recipe uses simple, accessible ingredients that pack in big flavor. You might already have many of these on hand!

• Corned beef: Chopped into small pieces. You can use leftover corned beef or deli-style for convenience.
• Sauerkraut: Drained and rinsed for a tangy kick without overpowering the dish.
• Swiss cheese: Shredded for that creamy, melty finish.
• Butter: Unsalted, for sautéing and adding richness.
• Onion: Finely diced for a subtle sweetness.
• Flour: All-purpose, for thickening the soup (use gluten-free flour if needed).
• Beef broth: Adds depth and complements the corned beef beautifully.
• Heavy cream: For a luxuriously creamy texture. You can swap with half-and-half for a lighter version.
• Dijon mustard: Just a tablespoon for that classic Reuben tang.
• Caraway seeds: Optional, but they add an authentic deli-style flavor.
• Salt and pepper: To taste.

These ingredients work harmoniously to deliver the perfect balance of creaminess, tang, and savory goodness.

Equipment Needed

You don’t need anything fancy to make this Reuben soup, which is part of its charm. Here’s what you’ll need:

• Large pot or Dutch oven: A sturdy pot is essential for evenly cooking the soup.
• Wooden spoon: Great for stirring without scratching your cookware.
• Knife and cutting board: For chopping the corned beef and onion.
• Ladle: Perfect for serving your soup neatly into bowls.

If you don’t have a Dutch oven, any heavy-bottomed pot will work just fine. The key is even heat distribution to prevent sticking.

Preparation Method

Follow these simple steps to create the ultimate Reuben soup:

1. Prep your ingredients: Chop the corned beef into small pieces, dice the onion, and shred the Swiss cheese. Drain and rinse the sauerkraut to remove excess brine.
2. Sauté the onion: In a large pot, melt the butter over medium heat. Add the diced onion and cook until softened, about 5 minutes. Stir frequently to avoid burning.
3. Create the roux: Sprinkle the flour over the sautéed onion and stir until it forms a paste. Cook for 1-2 minutes to remove the raw flour taste.
4. Add the broth: Gradually pour in the beef broth, whisking constantly to prevent lumps. Bring the mixture to a gentle boil, then reduce the heat to a simmer.
5. Add the cream and seasonings: Stir in the heavy cream, Dijon mustard, caraway seeds (if using), and a pinch of salt and pepper. Simmer for 5 minutes, allowing the flavors to meld.
6. Add the corned beef and sauerkraut: Stir in the chopped corned beef and rinsed sauerkraut. Simmer for an additional 10 minutes, stirring occasionally.
7. Finish with Swiss cheese: Reduce the heat to low and slowly add the shredded Swiss cheese, stirring until melted and smooth.
8. Serve: Taste and adjust seasoning if needed. Ladle the soup into bowls and garnish with extra cheese or a sprinkle of caraway seeds for a finishing touch.

This soup is best enjoyed hot and fresh, but you can make it ahead for even deeper flavors.

Cooking Tips & Techniques

• Don’t skip rinsing the sauerkraut: This step ensures the tanginess doesn’t overpower the soup.
• Use freshly shredded cheese: Pre-shredded cheese can sometimes make the soup gritty due to added stabilizers.
• Low and slow for the cheese: When adding the Swiss cheese, keep the heat low to prevent curdling.
• Thicken to your liking: If the soup feels too thin, simmer it a bit longer. For thicker soup, add a tablespoon of cornstarch mixed with water.
• Taste as you go: Adjust salt and pepper at the end to ensure the perfect balance.

These tips will help you avoid common pitfalls and ensure a silky, flavorful Reuben soup every time.

Variations & Adaptations

• Gluten-free option: Swap the flour for gluten-free all-purpose flour or cornstarch.
• Lighter version: Use half-and-half instead of heavy cream and reduce the butter slightly.
• Add veggies: Toss in diced potatoes or carrots for added texture and nutrition.
• Make it spicy: Add a pinch of red pepper flakes or a splash of hot sauce for a kick.
• Vegetarian twist: Replace the corned beef with sautéed mushrooms and use vegetable broth.

Feel free to experiment based on your preferences—this soup is wonderfully forgiving!

Serving & Storage Suggestions

Here’s how to make the most of your Reuben soup:

• Serving temperature: Serve hot, straight from the pot. A sprinkle of shredded Swiss cheese on top makes it extra special.
• Pairings: Serve with crusty rye bread, pickles, or a side salad for a complete meal.
