- Olive Oil (1 tbsp) – Helps sauté leeks evenly without burning.
- Garlic (2 cloves, minced) – Adds subtle savory depth.
- Chicken or Vegetable Broth (6 cups) – Forms a flavorful liquid base.
- Heavy Cream (1 cup) – Gives velvety smoothness (optional for lighter version).
- Thyme (1 tsp) – Adds subtle earthy notes.
- Bay Leaf (1) – Gentle herbaceous background flavor.
- Salt and Pepper (to taste) – Enhances all flavors.
- Chives (for garnish) – Adds fresh, mild onion flavor and color.

3. Step-by-Step Instructions
Step 1: Prepare and Sauté Leeks
Clean leeks thoroughly to remove grit. Slice thinly. In a large pot, heat butter and olive oil over medium heat. Add leeks and sauté for 5–7 minutes until soft and fragrant. Add garlic and cook 1 more minute.
Step 2: Add Potatoes and Broth
Add diced potatoes, thyme, bay leaf, and broth. Bring to a boil, then reduce to a simmer. Cover and cook for 20 minutes, or until potatoes are tender.
Step 3: Blend the Soup
Remove the bay leaf. Use an immersion blender to puree until smooth, or carefully transfer in batches to a countertop blender. Blend until creamy and lump-free.
Step 4: Add Cream and Adjust Seasoning
Return the blended soup to the pot. Stir in heavy cream and heat gently over low-medium heat. Season with salt and pepper to taste.
Tip: Avoid boiling after adding cream to prevent separation.
Step 5: Serve
Ladle into bowls and garnish with fresh chives. Serve with crusty bread or a side salad for a complete meal.
4. Tips and Variations
- Extra flavor: Sauté leeks slowly to caramelize slightly for a sweeter, deeper taste.
- Thicker soup: Mash a few potatoes before blending or use slightly less broth.
- Add-ons: Top with crispy bacon bits, grated cheese, or croutons.
- Herb variations: Dill, parsley, or tarragon can be used instead of thyme.
- Make-ahead: Soup can be prepared a day ahead and reheated gently.
5. Serving Suggestions
- Sides: Crusty baguette, garlic bread, or simple green salad.
- Toppings: Fresh chives, a swirl of cream, or croutons.
- Drinks: Pairs well with white wine, light beer, or herbal tea.
- Occasions: Ideal for cozy weeknights, lunch gatherings, or as an appetizer for dinner parties.
6. Storage and Reheating Instructions
- Refrigerator: Store in an airtight container for up to 3 days.
- Freezer: Freeze for up to 1 month; best reheated gently.
- Reheating: Warm on stovetop over low-medium heat. Add a splash of broth or cream if soup thickened in storage.
7. Recipe Notes
- Use only the white and light green parts of leeks for best flavor.
- Blend thoroughly for a smooth, velvety texture.
- Heavy cream is optional but recommended for a classic bisque-like finish.
- Soup flavors improve if prepared a few hours ahead.
