Ingredients
- 1 tablespoon butter
- 1 tablespoon olive oil
- 2 large leeks, thinly sliced (white and pale green parts only)
- 1 teaspoon salt
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon minced fresh garlic
- 2 pounds russet potatoes, peeled and cut into 1-inch cubes
- 6 cups low-sodium vegetable broth
- 3 sprigs fresh thyme
- 1/2 cup heavy cream
- Croutons, for garnish
- Chopped fresh parsley, for garnish
- Chopped fresh chives, for garnish
Instructions
- Sauté the Leeks
In a large soup pot or Dutch oven, melt the butter over medium heat. Add the olive oil, followed by the sliced leeks. Season with salt and pepper, and cook for about 6 minutes, stirring occasionally, until softened and fragrant. - Add Garlic and Potatoes
Stir in the minced garlic and cook for about 15 seconds. Add the cubed potatoes and cook briefly, about 20 seconds, to coat them in flavor. - Simmer the Soup
Pour in the vegetable broth and add the thyme sprigs. Bring the mixture to a gentle boil, then reduce heat, cover, and simmer for 22 to 25 minutes, or until the potatoes are very soft. - Blend Until Smooth
Remove the thyme sprigs. Using an immersion blender, blend the soup until creamy and smooth. Avoid over-blending to prevent a glue-like texture. - Finish with Cream
Stir in the heavy cream and taste for seasoning. Adjust the salt and pepper if needed. - Serve
Ladle into bowls and garnish with croutons, fresh parsley, and chives.
Tips for Success
- Avoid Over-Blending: Potatoes can take on a sticky texture if blended too long. If necessary, puree lightly and pass the soup through a fine sieve for a silky finish.
- Roasting Option: For deeper flavor, roast or bake the potatoes before adding them to the pot.
- Texture Variation: If you prefer some chunkiness, reserve a small portion of cooked potatoes and leeks before blending and stir them back into the soup.
Serving Ideas
This soup pairs beautifully with:
- Warm homemade rolls or crusty artisan bread
- A simple green salad
- Roasted vegetables
- Grilled or smoked chicken for a heartier meal
Storage and Reheating
- Refrigerate: Store in an airtight container for up to 4 days.
- Freeze: Freeze for up to 2 months. Leave out the cream before freezing and add it when reheating for the best texture.
- Reheat: Warm gently on the stovetop over low heat, stirring occasionally. Do not boil after adding cream.
