• 4 cups vegetable or chicken broth

Cooking Directions

Step-by-Step Preparation Method:

Step 1: Prepare the leeks

• Slice the leeks lengthwise and wash thoroughly to remove any dirt between the layers. Slice thinly.

Step 2: Sauté the aromatics

• In a large pot, heat butter and olive oil over medium heat.
• Add chopped onion, garlic, and leeks. Sauté for about 6–8 minutes until softened and fragrant, but not browned.

Step 3: Add potatoes and broth

• Add diced potatoes, salt, pepper, and thyme (if using). Stir well.
• Pour in the broth, bring to a boil, then reduce heat and simmer for 20–25 minutes, until the potatoes are tender.

Step 4: Blend the soup

• Once the vegetables are soft, remove from heat.
• Use an immersion blender (or regular blender) to puree until smooth and creamy.
• Return the soup to the pot.

Step 5: Add cream and adjust seasoning

• Stir in the cream and gently reheat without boiling.
• Taste and adjust seasoning with salt and pepper.

Step 6: Prepare the crispy shallots

• In a small skillet, heat oil over medium heat.
• Add thinly sliced shallots and fry, stirring frequently, until golden brown and crisp (about 3–5 minutes).
• Remove with a slotted spoon and drain on paper towels. Sprinkle lightly with salt.

Step 7: Serve

• Ladle soup into bowls, drizzle with a bit of cream if desired, and top with crispy shallots and fresh herbs.

How to Serve

• Serve hot, garnished with crispy shallots, fresh herbs, and a drizzle of cream or olive oil.
• Pair with crusty bread, baguette slices, or garlic croutons.
• For a light meal, add a side salad or serve with grilled cheese sandwiches.

Recipe Tips

• Clean your leeks thoroughly — they often hide grit inside.
• If the soup is too thick, add a bit more broth to adjust the consistency.
• Use Yukon Gold potatoes for the creamiest texture.
• Don’t rush the sautéing of the leeks — that’s where the flavor builds.
• For extra richness, stir in a knob of butter right before serving.

Recipe Variations

1. Vegan Potato Leek Soup

2. Cheesy Potato Leek Soup

3. Bacon Lover’s Version
