Instructions

Soup

  1. Step 1: Melt the butter in a large pot over medium heat. Add the garlic and leeks and sauté for 7 minutes, until soft and sweet.

  2. Step 2: Add the potatoes and broth. Turn up the heat and bring to a simmer, then cover the pot and lower the heat so the soup simmers gently. Simmer for 25 minutes, or until the potatoes are very soft and almost falling apart.

  3. Step 3: Turn off the stove and purée with a stick blender just until smooth. Do not over-purée, or the soup can become sticky.

  4. Step 4: Add the salt and pepper, then stir in the cream.

  5. Step 5: Serve drizzled with cream and sprinkled with chives and croutons.

Croutons

  1. Step 6: Preheat the oven to 180°C/350°F (160°C fan-forced). Drizzle the bread with melted butter or spray it with oil. Bake for 5 minutes, or until golden and crunchy. Sprinkle with a pinch of salt while hot.

Notes

If you can’t get leeks, substitute brown, white or yellow onions. Chop them and sauté over low heat for 10 to 12 minutes, until soft and sweet; don’t let them caramelize.

If using a blender instead of a stick blender, mash the potatoes in the liquid first, then transfer the mixture to the blender and pulse just until smooth.

Starchy or all-purpose potatoes work well; the recipe names Sebago, Russet and Maris Piper. A little extra cream and crusty bread are also suggested for serving.
