Tips, Variations, and Substitutions
Tips for the Perfect Creamy Reuben Soup:
-
Drain the Sauerkraut Well: Too much liquid will make the soup sour or watery.
-
Use Good Corned Beef: Homemade or deli-sliced works great; avoid canned.
-
Add Cheese Gradually: Stir slowly over low heat to prevent curdling.
-
Reheat Gently: Avoid boiling — it can separate the cream.
Variations:
-
Reuben Chowder Style: Add diced potatoes for a thicker, chunkier soup.
-
Low-Carb Version: Skip the flour and thicken with a bit of cream cheese instead.
-
Reuben Dip Twist: Serve thickened soup as a warm dip with rye toast points.
-
Vegetarian Option: Use veggie broth, omit beef, and add chopped mushrooms for depth.
Substitutions:
-
Swiss Cheese → Gruyère or Provolone: Melts beautifully and has similar flavor.
-
Beef Broth → Chicken Broth: Slightly lighter but still flavorful.
-
Thousand Island Dressing → Russian Dressing or Mayo + Ketchup Mix.

Frequently Asked Questions (FAQ)
1. Can I make Creamy Reuben Soup ahead of time?
Yes! It reheats beautifully. Store in an airtight container in the fridge for up to 3 days. Reheat gently over low heat and add a splash of milk or broth if it thickens too much.
2. Can I freeze it?
Because of the cream and cheese, freezing isn’t ideal — the texture may separate. For make-ahead meals, freeze before adding dairy, then stir in cream and cheese after thawing and reheating.
3. Can I use deli corned beef?
Yes, it works great! Just chop it into small pieces before adding.
4. What kind of sauerkraut works best?
Use a good-quality refrigerated brand or homemade sauerkraut — it’s fresher and less salty than canned.
5. Can I make it gluten-free?
Yes — replace flour with 1 tablespoon cornstarch mixed into cold broth. Use gluten-free rye-style crackers if desired.
6. Can I make it in a slow cooker?
Yes! Sauté onions and flour first, then add everything except cream and cheese. Cook on Low for 6 hours, stir in cream and cheese before serving.
7. Can I adjust the tanginess?
Absolutely. Add more sauerkraut or dressing for a punchier flavor, or balance with extra cream for milder taste.
