Ingredients
- 2 pounds Yukon Gold potatoes, peeled and diced
- 4 large leeks, white and light green parts only, washed and sliced
- 4 cups vegetable broth
- 1/2 cup heavy cream (or alternative for vegan option)
Instructions
- Step 1: 1
Sauté The Leeks: In a large pot or Dutch oven, melt 2 tablespoons of unsalted butter over medium heat. Add the sliced leeks and sauté for 5-7 minutes until tender and slightly golden. This slow cooking caramelize the natural sugars, adding sweetness to the soup.
💡 Leeks take time to develop flavor - don't rush this step!
- Step 2: 2
Add Potatoes and Broth: Add the diced potatoes and vegetable broth to the pot. Bring to a simmer, then reduce heat to medium and cook for 15-20 minutes until the potatoes are tender. The broth should begin to reduce slightly as it simmers.
💡 For extra richness, add 1 teaspoon of white miso paste at this stage.
- Step 3: 3
Puree the Soup: Using an immersion blender (or transferring to a stand blender in batches), puree the soup until completely smooth. Add the heavy cream and stir to combine. Return any solids to the pot for balanced texture.
💡 For vegan version, substitute cream with coconut milk or oat milk
- Step 4: 4
Season and Serve: Season with salt and fresh ground pepper to taste. Ladle into bowls and garnish with fresh thyme or chives just before serving. A drizzle of olive oil adds visual appeal.
💡 For presentation, use a chime garnisher for perfectly placed herbs.
Why This Recipe Works
⏰ Effortless Preparation
This four-ingredient soup simplifies weeknight cooking by using common staples. The sauté step takes just 10 minutes total, and no special equipment is needed beyond a pot and blender.
💰 Budget-Friendly
Potatoes and leeks are affordable staples that become gourmet when cooked properly. One small leek can yield multiple meals when frozen for future use.
👥 Versatile Serving
Serves as a first course with bread or a full meal with added roasted chicken or salmon. Vegetarians and carnivores will both appreciate this soup's flexibility.
🌟 Flavor Layering
The slow sauté of leeks builds complexity while the cream adds richness. The final texture remains smooth without becoming too dense.
Ingredient Notes & Substitutions
Yukon Gold Potatoes
These mid-starch potatoes maintain velvety texture when cooked and blended. For a different experience, try sweet potatoes for richer flavor or red potatoes for firmer texture.
Substitutions: Russet or all-purpose potatoes (reduce cooking time slightly)
Leeks
The gentle onion flavor is essential here. Avoid using green onions or scallions which add sharper flavors. For a vegan version, use 1/2 cup minced shallots as a substitute.
Substitutions: Leek powder or dried leek granules (use 1 tbsp for fresh leeks)
Vegetable Broth
Low-sodium varieties maintain control over seasoning. Avoid using chicken broth as it will overpower the subtle leek flavor. For extra depth, add 1/4 cup white wine along with the broth.
Substitutions: Chicken broth (1/4 tsp thyme for flavor balance)
Heavy Cream
Adds richness but isn't essential - you can omit for a lighter version. For dairy-free, try full-fat coconut milk or oat milk. Any type of milk works but heavy cream gives the most luxurious texture.
Substitutions: 1/2 cup milk of choice + 1/2 cup Greek yogurt
Pro Tips for Perfect Potato Leek Soup
🥢 Leek Preparation
Trim the dark green parts (they're bitter) but use the lighter green and white sections. Soak in cold water to remove any grit between the leaves before slicing.
🍲 Consistency Secret
Let cool slightly before blending - hot soup creates steam that can reduce liquid in blender. For chunkier texture, reserve 20% of puree for garnish over smooth base.
🌿 Flavor Enhancement
A drop of balsamic vinegar brightens the soup. Add at the end for a sophisticated tang that cuts through richness perfectly.
🧊 Freezing Tips
Freeze in 1-cup airtight containers. Thaw in refrigerator overnight, then reheat gently. Add cream after reheating to prevent curdling.
Variations & Customizations
Herbed Variation
Add fresh thyme, chervil, or tarragon during sauté. These aromatic herbs complement the leeks' gentle flavor while adding complexity.
Cheesy Upgrade
Stir in 1/4 cup grated Parmesan after blending for a protein boost. The cheese adds a nutty depth that pairs beautifully with the cream.
Citrus Infusion
Finish with a squeeze of lemon juice for brightness. Citrus also helps balance the richness of the cream, creating balance similar to classic vichyssoise.
Spicy Kick
Add 1/4 tsp of crushed red pepper flakes during cooking. The mild heat accentuates the natural sugars while maintaining an elegant profile.
Serving Suggestions & Pairings
🍽️ Best Served With:
- Crusty sourdough with butter - The tangy crust contrasts beautifully with creamy soup
- Charcuterie board - Complements earthiness with cured meats
- Oven-toasted oyster crackers - Adds textural contrast
🍷 Drink Pairings:
- Chardonnay with leesy notes - Enhances creaminess
- Muscat d'Alexandrie - Aromatic sweet wine for dessert pairing

Make-Ahead Instructions & Storage
Make-Ahead Tips
Prepare 2 days in advance. Store pureed soup in airtight containers until ready to add cream. Add dairy just before serving to maintain freshness.
Refrigerator Storage
Keep in airtight containers up to 5 days. Gently reheat in saucepan until warmed through, adding more broth as needed.
Freezer Storage
Pour into 8-ounce portions. Freeze up to 3 months. Thaw overnight in refrigerator before reheating.
Reheating Instructions
For best results, reheat on low heat. Avoid boiling which can make the potatoes break down. Add a splash of cream post-reheating.
Troubleshooting & Common Questions
Q: Soup is too thin?
A: Simmer a bit longer next time or add 20g cooked rice while blending. For thickening existing soup, make a slurry with cornstarch and water, then simmer gently.
Q: Soup lacks depth?
A: Caramelize leeks properly for flavor development. Add 1/2 shallot with leeks or use 1/2 tsp smoked paprika before adding broth. For umami, add a Parmesan rind while simmering.
A: Trim any remaining green parts. Soak in salt water for 15 minutes before washing. Cook low and slow to avoid burning, which creates bitterness.
A: Cool completely before storing. For 24+ hours storage, add cream post-reheating. Freeze without cream for best results.
