This recipe elevates the humble potato and leek to new heights, showcasing their natural sweetness and earthy flavors through the magic of roasting.

Why Roasting Makes All the Difference
Roasting the potatoes and leeks before adding them to the soup is the key to unlocking their full potential. This process caramelizes the vegetables, intensifying their sweetness and creating a complex depth of flavor that simply can't be achieved by sautéing or boiling. The resulting soup is far more nuanced and delicious than a traditional version.
Ingredients You'll Need:
- 2 lbs Yukon Gold potatoes, peeled and cubed – Yukon Golds are ideal for their creamy texture and subtle sweetness.
- 2 large leeks, white and light green parts only, thinly sliced and thoroughly washed – Washing the leeks is crucial to remove any trapped grit.
- 2 tbsp olive oil – Use a good quality olive oil for the best flavor.
- 1 tsp salt – Adjust to taste.
- 1/2 tsp black pepper – Freshly ground is always best.
- 4 cups vegetable broth – Homemade broth adds extra depth, but store-bought works well too.
- 1 cup heavy cream or coconut milk – For a richer, creamier soup. Coconut milk provides a delightful twist.
- 2 tbsp fresh thyme leaves – Adds a wonderful herbaceous aroma and flavor.
- Optional garnishes: Fresh chives, croutons, a swirl of cream, or a sprinkle of grated Parmesan cheese.
Step-by-Step Instructions:
-
Roast the Vegetables: Preheat your oven to 400°F (200°C). Toss the cubed potatoes and sliced leeks with olive oil, salt, and pepper on a large baking sheet. Roast for 30-40 minutes, or until the potatoes are tender and slightly caramelized, stirring halfway through.
-
Simmer the Soup: Transfer the roasted vegetables to a large pot or Dutch oven. Add the vegetable broth and thyme leaves. Bring to a simmer, then reduce heat and cook for 15-20 minutes, allowing the flavors to meld.
-
Blend the Soup: Carefully transfer the soup to a blender (or use an immersion blender) and blend until smooth and creamy. Work in batches if necessary.
-
Stir in the Cream: Return the blended soup to the pot. Stir in the heavy cream or coconut milk. Heat through gently – do not boil.
-
Serve and Enjoy: Ladle the soup into bowls and garnish as desired. The warmth of this soup, paired with the crispy garnish, creates a truly unforgettable culinary experience.
Tips and Variations:
- Add other vegetables: Consider adding roasted carrots, parsnips, or celery for extra flavor and nutrients.
- Spice it up: A pinch of red pepper flakes adds a touch of heat.
- Make it vegan: Use coconut milk instead of heavy cream and ensure your broth is vegan-friendly.
- Boost the flavor: Add a bay leaf during simmering for a more complex flavor profile, removing it before blending.
