Chef’s Pro Tips for Perfect Results

• Clean Leeks Thoroughly: Leeks tend to trap dirt between layers. Slice and rinse carefully to avoid grit in your soup.
• Sauté for Flavor: Cooking leeks and onions in oil first brings out their natural sweetness and builds depth.
• Simmer Gently: Let the soup bubble gently rather than boil vigorously to keep the flavors delicate and avoid breaking the potatoes apart too much.
• Blend Smoothly: Use an immersion blender or a countertop blender for a creamy, silky texture. Blend in batches if necessary.
• Finish with Fresh Herbs: Chopped chives, parsley, or a drizzle of cream on top elevate both flavor and presentation.

Ingredients in Leek and Potato Soup

Here’s what makes this soup a comforting classic. (Note: the full ingredients list, including measurements, is provided in the recipe card directly below.)

Oil

The base for sautéing your leeks and onions, bringing a gentle richness without overpowering the vegetables.

Leeks

Soft, sweet, and aromatic, leeks are the heart of this soup. They lend a subtle onion-like flavor and melt into the creamy base.

Onion

Roughly chopped onions add depth and natural sweetness that balance the earthy potatoes.

Potatoes

Diced into bite-sized pieces, potatoes give the soup body, thickness, and that smooth, velvety mouthfeel after blending.

Dried Thyme

A fragrant herb that complements the mildness of leeks and potatoes. It adds subtle warmth and complexity.

Vegetable Stock

The liquid backbone of the soup, it keeps it light yet flavorful. Stock (or broth) ensures a naturally rich taste.

Milk or Single Cream (Optional)

For those who love a silky, creamy texture. A splash at the end can elevate the soup to indulgent levels.

Chives

Finely chopped and sprinkled on top for freshness, color, and a mild oniony bite.

Instructions

Preheat Your Equipment: Warm your saucepan over medium heat and add the oil. Preheating helps release the flavors of the vegetables evenly.

Sauté the Vegetables: Add the sliced leeks and chopped onion. Cook gently until soft and fragrant, stirring often to prevent browning. This stage develops the flavor base and releases natural sweetness.

Add Potatoes and Thyme: Stir in the diced potatoes and sprinkle with dried thyme. Toss to coat and allow the potatoes to absorb the aromatic flavors for a minute or two.

Pour in Vegetable Stock: Add the stock and bring the mixture to a gentle simmer. Cover and cook until the potatoes are tender, about 20–25 minutes.

Blend the Soup: Remove from heat and use an immersion blender to purée until smooth. For a chunkier texture, blend only part of the soup. Adjust consistency by adding a little extra stock if needed.

Incorporate Milk or Cream: Stir in milk or single cream if desired. This adds richness and creates that luxurious, velvety texture.

Season to Taste: Taste and adjust seasoning with salt and pepper. Remember, simple flavors can be enhanced with a touch more thyme or herbs.

Serve and Garnish: Ladle the soup into bowls, swirl in extra cream if using, and sprinkle with fresh chopped chives. Serve hot and enjoy immediately.
