This Reuben Soup recipe transforms the classic Reuben sandwich into a comforting and flavorful soup. It combines tender corned beef, tangy sauerkraut, and melted Swiss cheese in a savory broth, offering a delightful twist on a beloved classic.
For a vegetarian version, replace the corned beef with vegetarian 'corned beef' or smoked tofu. Rinsing the sauerkraut is optional; skip it for a tangier soup. Store leftover soup in an airtight container in the refrigerator for up to 3-4 days or freeze for up to 2-3 months. Reheat on the stovetop or in the microwave. You can add a pinch of red pepper flakes or a dash of hot sauce for a spicy kick. Experiment with Gruyere cheese for a nutty flavor.
