The choice of ingredients plays a vital role in the success of this soup.

Step-by-Step Instructions
Making Reuben Soup is straightforward and rewarding. Follow these easy steps to create a delightful dish that will impress your family.
- In a large pot, melt 2 tablespoons of butter over medium heat. Add the diced onion and sauté until translucent, which should take about 5 minutes. This step allows the onions to release their sweetness and adds depth to the soup.
- Next, stir in the chopped corned beef and sauerkraut, cooking them together for a few minutes. This will help the flavors meld together. If you prefer a deeper flavor, don’t hesitate to cook them for an additional two to three minutes.
- Add 4 cups of beef broth and bring the mixture to a boil. Once boiling, reduce the heat to a simmer and let it cook for 15 minutes. This simmering process will enhance all the flavors as they combine.
- After simmering, stir in 1 cup of heavy cream, 1 cup of shredded Swiss cheese, and 1 tablespoon of Dijon mustard. Continue to cook until the cheese is melted and the soup is heated through. This step is crucial for achieving that creamy, dreamy consistency.
- Season the soup with salt and pepper to taste. Remember to taste as you go; this ensures the flavors are just right.
- Serve hot, garnished with chopped parsley. This final touch not only adds a pop of color but also a fresh flavor that rounds out the dish.
Delicious Ways to Serve This Soup
This Reuben Soup is delightful on its own, but with a few sides, you can create a well-rounded meal. Consider pairing it with:
- Crusty rye bread for dipping or to soak up the delicious broth.
- A simple green salad drizzled with vinaigrette to add freshness.
- Pickles or potato chips for a traditional touch and added crunch.
- If you’re hosting friends, serve it alongside a selection of craft beers for a casual yet delightful dining experience.
For special occasions or colder nights, this soup can be a centerpiece, warming both heart and home.
Proper Storage and Reheating Methods
If you have leftovers (which is likely, considering how delightful it is!), store them in an airtight container in the refrigerator for up to three days. To freeze, let the soup cool completely, then transfer portions into freezer-safe containers. It can be frozen for up to three months. When reheating, it’s best to do so on the stovetop over medium heat. Add a splash of broth or cream if it thickens too much. Stir frequently to avoid sticking and ensure even heating.
Essential Cooking Tips
Here are some pro tips to consider while making this flavorful soup:
- Ensure your corned beef is well-seasoned. If you are using leftovers, a quick tip is to warm it slightly in the microwave before adding it to the pot to reduce cooking time.
- Don’t skip the step of letting the soup simmer; this is crucial for developing a strong, cohesive flavor.
- If you find the soup to be too thick after adding the cream, feel free to add an additional cup of broth until your desired consistency is reached.
- Watch the saltiness. Beef broth can be quite salty, so it’s wise to check the flavor before adding additional salt.
Possible Tweaks and Variations
This Reuben Soup recipe is versatile! Here are some ideas to customize it to your palate:
- Swap the Swiss cheese for Gruyère or provolone for alternate flavor profiles.
- For a lighter version, use half-and-half instead of heavy cream.
- If you prefer a spicier kick, add a pinch of red pepper flakes or a splash of hot sauce while cooking.
- Vegetarians can substitute corned beef with mushrooms or tempeh for a hearty meat-free alternative.
Common Questions and Helpful Answers
Here are some frequently asked questions about Reuben Soup that may help you get the best out of your cooking experience:
- Can I use sauerkraut from a can? Absolutely! Canned sauerkraut is a great alternative. Just make sure to drain it thoroughly to prevent excess liquid.
- How can I thicken the soup? If the soup ends up too thin for your liking, you can thicken it by mixing a tablespoon of cornstarch with a bit of cold water and stirring it into the simmering soup.
- What should I do if I don’t have Dijon mustard? You can use yellow mustard as a substitute, but keep in mind it will alter the flavor slightly.
- Can this soup be made ahead of time? Yes! The flavors will deepen over time, making it even tastier. Just hold off on adding the cream until you reheat it.
- Is this soup gluten-free? As written, the recipe is not gluten-free due to the rye bread and possible gluten in the beef broth. Look for gluten-free alternatives for both to accommodate dietary needs.
