- 2 cloves garlic, minced
- 1/4 cup all-purpose flour
- 4 cups beef broth
- 1 1/2 cups half-and-half
- 2 cups chopped cooked corned beef

How to Make Easy Creamy Reuben Soup Recipe
Step-by-Step Instructions:
Step 1: Prepare the Base In a large pot or Dutch oven, melt the butter over medium heat. Add the finely chopped onion and cook for 3-4 minutes until softened and translucent. Add the minced garlic and cook for another 30 seconds until fragrant.
Step 2: Create the Roux Sprinkle the flour over the onion and garlic mixture, stirring constantly for about 1 minute to create a light roux. This will help thicken your soup and prevent any lumps from forming.
Step 3: Add the Liquids Gradually whisk in the beef broth, making sure to scrape up any browned bits from the bottom of the pot. Bring the mixture to a gentle boil, then reduce heat and simmer for 5 minutes until slightly thickened.
Step 4: Incorporate the Cream Slowly stir in the half-and-half, being careful not to let the soup boil rapidly as this could cause curdling. Heat through until steaming.
Step 5: Add the Stars of the Show Stir in the chopped corned beef, drained sauerkraut, caraway seeds, and Dijon mustard. Let the soup simmer gently for 10-15 minutes to allow all the flavors to meld together beautifully.
Step 6: Finish with Cheese Remove the pot from heat and gradually stir in the shredded Swiss cheese until completely melted and incorporated. Season with salt and pepper to taste, keeping in mind that the corned beef and sauerkraut already add saltiness to the dish.
Step 7: Serve and Enjoy Ladle the soup into bowls and top with rye croutons if desired for that extra Reuben sandwich experience.
Helpful Tips
Choose Quality Corned Beef: Use leftover homemade corned beef or high-quality deli corned beef for the best flavor. Avoid overly processed versions that might become tough when reheated.
Don’t Skip the Caraway Seeds: These seeds are essential for authentic Reuben flavor. If you only have ground caraway, use about 1/2 teaspoon instead.
Rinse the Sauerkraut: If you prefer a milder tang, rinse the sauerkraut before draining and chopping. For maximum flavor, use it straight from the jar.
Temperature Control: Keep the heat at medium or medium-low once you add the half-and-half to prevent curdling. The soup should be hot but not aggressively bubbling.
Cheese Melting Trick: Remove the pot from heat before adding cheese to ensure smooth melting without separation.
