Ingredients for Reuben Chowder
Crafting the perfect Reuben Chowder requires selecting the right components to build those familiar, beloved Reuben flavors. Here’s what you’ll need:
The Meat: Corned Beef
Tender, flavorful corned beef is non-negotiable. Leftover corned beef from a holiday roast is ideal for both flavor and convenience. Dice or shred the beef into bite-sized pieces. The rich, salty notes of the beef are the heart of this corned beef soup recipe.
The Vegetables: Potatoes, Sauerkraut, and Aromatics
- Potatoes: Essential for chowder, providing body and a creamy texture. Russet or Yukon Gold potatoes are excellent choices for this creamy potato soup with beef.
- Sauerkraut: Adds the signature tangy element. Rinsed and drained, it provides that piquant punch, making this a true sauerkraut soup.
- Aromatics: Onions and garlic form the foundational flavor base, sautéed until fragrant for depth and warmth.
The Broth: Creating a Creamy Base
The broth harmonizes ingredients. You’ll need quality beef broth, milk or half-and-half for richness, and Dijon mustard for subtle tang. Freshly grated Swiss cheese is crucial for a Swiss cheese chowder, melting for a nutty, creamy finish.
How to Make Reuben Chowder Step-by-Step
Making this hearty Reuben Chowder is straightforward. Follow these instructions for a perfect bowl:
Sautéing the Vegetables
Melt butter in a large pot. Add chopped onions and sauté until softened (5-7 minutes). Stir in minced garlic for another minute until fragrant.
Building the Roux and Simmering
Sprinkle flour over vegetables; cook, stirring, for 1-2 minutes. Gradually whisk in beef broth, ensuring no lumps. Bring to a simmer, add diced potatoes. Reduce heat, cover, and simmer for 15-20 minutes until potatoes are tender.
Finishing with Cream and Cheese
Stir in corned beef, rinsed sauerkraut, milk (or half-and-half), and Dijon mustard. Heat gently (do not boil). Slowly stir in freshly grated Swiss cheese until melted and creamy. Season with salt and pepper.
Making the Rye Croutons
Cube rye bread, toss with olive oil/butter, and toast in a pan or oven (375°F/190°C) until golden brown and crisp. These rye bread croutons add delightful crunch and extra Reuben flavor.
Tips for the Best Reuben Soup
Elevate your Reuben Chowder from great to unforgettable with these expert tips:
Rinsing the Sauerkraut
Rinsing and draining sauerkraut reduces intense brininess, balancing the flavor. You want zest, not overpowering sourness, in your sauerkraut soup.
Shredding Cheese Fresh
Always grate Swiss cheese fresh for the creamiest, silkiest Swiss cheese chowder. Pre-shredded cheese can contain anti-caking agents preventing smooth melting.


Adjusting Consistency
Chowders should be thick. If your Reuben Soup is too thick, thin with broth or milk. If too thin, simmer uncovered or add a cornstarch slurry.
Variations and Substitutions
Adapt your Reuben Chowder to different needs or schedules:
Slow Cooker Method
For a convenient slow cooker reuben soup, sauté aromatics, then transfer to slow cooker with beef broth, potatoes, and corned beef. Cook on low (6-8 hours) or high (3-4 hours). In the last 30 minutes, stir in sauerkraut, milk, Dijon, and Swiss cheese to melt and meld flavors.
Low-Carb Options
To reduce carbs, replace potatoes with cauliflower florets or daikon radish for similar texture. Ensure beef broth is sugar-free for a delicious, guilt-free Reuben Chowder.
Serving Suggestions
Your Reuben Chowder is a complete meal. Enhance it with garnishes: serve hot, topped with fresh rye bread croutons for crunch. A dollop of Thousand Island/Russian dressing or fresh dill/parsley adds a vibrant touch. Pair with a simple green salad.
Storing and Reheating Leftovers
Reuben Chowder often improves overnight. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat gently on the stovetop; add a splash of broth or milk if too thick. Avoid boiling to prevent dairy separation.
It can be frozen for 2-3 months, though potatoes might become mealy. Thaw overnight and reheat. For best texture, consider adding fresh potatoes upon reheating if freezing.
