Creamy Leek & White Bean Soup with Wine

serves 4-6 · 65-75 minutes · 15 minutes hands on · easy-medium

Ingredients

  • Large leeks (4, white and light green parts only, cleaned and sliced)
  • Garlic cloves (4, minced)
  • Extra virgin olive oil (1 Tbsp)
  • Dry white wine (1 cup, high-quality - Inglenook Blancaneaux or similar Rhône-style blend recommended)
  • Vegetable stock (6 cups)
  • White beans (1.5-2 cups cooked/canned with liquid - cannellini, great northern, or navy beans)
  • Bay leaves (2)
  • Salt (to taste, plus generous pinch for sweating leeks)
  • Fermented white pepper (to taste) OR freshly ground black pepper
  • Cayenne (pinch, optional)
  • Green onions (chopped, for garnish, optional)
  • French baguette (for croutons, optional)

Equipment

  • Large, heavy soup pot - for building flavor base
  • Immersion blender OR regular blender - for pureeing
  • Wooden spoon - for stirring

Instructions

Step 1: Slow-Caramelize the Leeks (10-15 minutes)

  1. Heat 1 Tbsp olive oil in large, heavy soup pot over medium-low heat
  2. Add sliced leeks and generous pinch of salt
  3. Cook lid off, stirring occasionally, for 10-15 minutes until:
    • Very soft and translucent
    • Sweet-smelling (not sharp/oniony)
    • Light golden edges appearing
    • Can easily smash with spoon against pot
  4. Pro tip: Don't rush this step - the slow caramelization builds maximum flavor depth
  5. If leeks start sticking, add 1-2 Tbsp stock to deglaze (adds flavor!)

Step 2: Add Garlic (1 minute)

  1. Stir in 4 cloves minced garlic
  2. Cook, stirring constantly, for about 1 minute until fragrant
  3. Don't let garlic brown or burn

Step 3: Double Wine Reduction (6-10 minutes) - Elle's Signature Technique

  1. First reduction: Add ½ cup white wine to pot
  2. Increase heat to medium
  3. Cook 3-4 minutes, stirring occasionally, until wine is mostly absorbed/evaporated
  4. Wine will soak into leeks like a sponge - this is perfect!
  5. You should smell less alcohol and more concentrated wine aroma
  6. Second reduction: Add remaining ½ cup white wine
  7. Cook another 3-4 minutes until reduced and concentrated
  8. This double reduction creates incredible depth and caramelized complexity

Altitude note: At 5,280 feet (Denver), wine reduces faster - watch closely and adjust timing to 3-4 minutes per batch

Step 4: Simmer the Soup (30 minutes)

  1. Add 6 cups vegetable stock, 2 bay leaves, and entire can of white beans (including liquid)
  2. Bring to a boil over medium-high heat
  3. Once boiling, reduce heat to low
  4. Cover with lid and simmer gently for 30 minutes
  5. Stir occasionally to ensure even cooking

Step 5: Remove Bay Leaves & Puree (5 minutes)

  1. Important: Fish out and discard both bay leaves before blending!
  2. Use immersion blender to puree soup directly in pot until completely smooth and creamy
  3. OR Transfer in batches to regular blender (only fill halfway, remove center cap, cover with towel)
  4. Blend 1-2 minutes until silky with no chunks
  5. The white beans create incredible creaminess without any dairy

Step 6: Final Seasoning & Serve

  1. Taste and adjust seasoning:
    • Add fermented white pepper (or black pepper) to taste
    • Pinch of cayenne for subtle warmth (optional)
    • More salt if needed
  2. Heat through over low heat for 2-3 minutes
  3. Ladle into bowls
  4. Optional garnishes: Chopped green onions, croutons from toasted baguette, drizzle of olive oil

Serving Suggestions

  • Serve hot immediately
  • Pairs beautifully with crusty bread
  • Can also be served chilled (like vichyssoise) - refrigerate and serve cold
  • Leftovers reheat beautifully; thin with splash of stock if needed

Notes

  • Slow leek cooking: The 10-15 minute low-and-slow method develops sweet, caramelized flavor that elevates the entire soup
  • Lid off for leeks: Allows moisture to evaporate and leeks to caramelize; lid goes on only for the 30-minute simmer
  • Double wine reduction technique: Elle's signature modification creates layered, concentrated wine flavor - more complex than single reduction
  • High-quality wine matters: Use a wine you'd enjoy drinking; the Inglenook Blancaneaux (Rhône-style white blend) adds beautiful stone fruit aromatics and full body
  • Bean liquid is key: Don't drain canned beans - the starchy liquid adds body and creaminess, replacing what rice would provide in original recipe
  • No rice needed: White beans provide all the thickening power and creamy texture, plus protein and fiber
  • Fermented white pepper: More complex and funky than regular black pepper - highly recommended if you have it
  • Altitude adjustments: At 5,280 feet, liquids boil at lower temp and reduce faster - watch wine reduction closely
  • Make-ahead: Soup keeps 3-4 days refrigerated; flavor deepens over time
  • Freezing: Freezes well up to 3 months; thaw and reheat gently
  • Customization: Original recipe uses basmati rice; this version swaps for beans and adds sophisticated wine reduction
  • Leek absorption: Leeks act like sponges and absorb wine immediately - this is perfect and allows flavor to penetrate deeply

Key Differences from Original Martha Rose Shulman Recipe

  • Leek cooking: Extended to 10-15 minutes low-and-slow (vs 5 min medium) for caramelization
  • Wine addition: 1 cup white wine in two-batch reduction (vs no wine in original)
  • Thickener swap: White beans replace basmati rice for protein, fiber, and creaminess
  • Stock reduction: 6 cups stock (vs 7 cups) to account for wine addition
  • Pepper upgrade: Fermented white pepper (vs regular black pepper) for complexity
  • Result: More sophisticated, wine-forward soup with deeper caramelized flavor
