Creamy Reuben Chowder: Deli-Style Crockpot Comfort

Turn your favorite deli sandwich into a rich, cozy chowder that simmers all day in the slow cooker. This Reuben-inspired soup brings together tender corned beef, tangy sauerkraut, and Yukon potatoes in a creamy, cheese-laced broth that tastes like a warm hug in a bowl.

With just 20 minutes of prep, you can set it and forget it, then come home to the most comforting dinner that's perfect for chilly evenings or game-day gatherings.

This slow-cooker Reuben chowder takes all the iconic flavors of the classic sandwich—salty corned beef, sour sauerkraut, caraway, and Swiss cheese—and transforms them into a luscious, spoonable soup.

The slow cooker does the heavy lifting, melding the ingredients into a deeply savory broth that's then enriched with cream cheese, heavy cream, and aged Swiss. It's the kind of meal that feels both nostalgic and new: familiar deli flavors in a format that's perfect for feeding a crowd or meal-prepping for the week.

Ingredients

Why this recipe works

Cooking the chowder low and slow gives the potatoes time to soften and absorb the beefy broth, while the sauerkraut mellows and releases its tangy character into the surrounding liquid.

The long simmer also allows the caraway seeds to infuse the entire pot with their warm, anise-like aroma, creating a depth of flavor that can't be rushed. This gentle cooking method ensures every spoonful tastes like it simmered all day, without any last-minute fuss.

The creamy finish is what sets this chowder apart. Adding cream cheese and heavy cream at the end—rather than at the start—prevents them from curdling or becoming greasy, and the Swiss cheese melts into a silky, stretchy binder that gives the soup body. The result is a velvety, luxurious texture that clings to each potato cube and piece of beef, making every bite feel indulgent.

Notes and substitutions

For the best flavor, use a good-quality cooked corned beef brisket—either from a deli counter or leftover from a holiday meal. If you can't find Bavarian sauerkraut, regular sauerkraut works; just be sure to drain it well to avoid a watery chowder.

Yukon Gold potatoes are ideal because they hold their shape during the long cook, but you can substitute red potatoes or even russets in a pinch.

Aged Swiss cheese, like Gruyère or Emmental, brings a nutty complexity that younger Swiss lacks. If you prefer a milder taste, use a young Swiss or even a combination of Swiss and mozzarella. The heavy cream and cream cheese are non-negotiable for that rich, velvety texture, but you can use half-and-half for a slightly lighter version—just know the chowder will be less decadent.

• cooked corned beef brisket: Use leftover cooked corned beef or substitute with cooked pastrami for a similar flavor.
• Bavarian sauerkraut: Regular sauerkraut works; rinse and drain if you prefer a milder tang.
• beef bone broth: Use low-sodium beef broth or chicken broth for a lighter base.
• aged Swiss cheese: Substitute with Gruyère or Emmental for a nutty, melty finish.
