Ingredients

1 tablespoon extra-virgin olive oil

1 medium leek, white and pale-green parts only, halved lengthwise and sliced crosswise 1/4 inch thick, rinsed well

1 bunch carrots (about 6), peeled and sliced crosswise 1/4 inch thick

2 teaspoons harissa

Coarse salt

3 cups homemade or store-bought low-sodium chicken stock

Garnish: 1 tablespoon chopped fresh flat-leaf parsley

Preparation

Heat oil in a large saucepan over medium heat. Cook leek until just soft, 4 to 5 minutes. Stir in carrots and harissa. Season with salt. Cook until carrots are just soft, 8 to 10 minutes. Add chicken stock, and bring to a simmer. Cook until vegetables are tender, 10 to 12 minutes.

Puree half the soup in a blender until smooth. (For safety, remove cap from hole in lid, and cover with a dish towel to prevent spattering.) Stir puree into remaining soup in pan. Divide soup among 4 bowls, and garnish with parsley.
