Ingredients
  

  • Garlic 1 whole head, with loose outer skin: Adds rich, roasted sweetness with a hint of smokiness.
  • Leeks 3 large, white and light green parts, cleaned and sliced: Contributes mild onion-like flavor and texture.
  • Olive oil 2 tablespoons, for roasting and sautéing: Helps develop rich flavor during roasting.
  • Vegetable broth or chicken broth 4 cups, unsalted or low-sodium: Adjust salt seasoning as needed based on broth saltiness.
  • Salt to taste: Enhances natural flavors.
  • Freshly ground black pepper to taste: Adds subtle heat and complexity.

Equipment

  • Baking sheet
  • Sharp Knife
  • Soup pot or Dutch oven
  • Wooden spoon
  • Ladle

Method
 

  1. Preheat your oven to 180°C (350°F).
  2. Place the whole head of garlic on a baking sheet and drizzle with 1 tablespoon of olive oil.
  3. Roast garlic for 35–40 minutes, checking after 30 minutes for soft, golden cloves.
  4. While garlic roasts, heat remaining olive oil in a large soup pot over medium heat.
  5. Add sliced leeks and sauté for 7–8 minutes, until soft and fragrant.
  6. Once garlic is done roasting, let it cool for 5–10 minutes, then squeeze the soft cloves out of their skins directly into the pot with the leeks.
  7. Add the vegetable or chicken broth to the pot, bring to a simmer, and cook gently for 15–20 minutes to allow flavors to fully meld and develop depth.
  8. Season with salt and freshly ground black pepper to taste.
  9. For a smoother soup, use an immersion blender directly in the pot or transfer to a blender in batches. Let cool slightly before blending hot liquids to avoid splattering.
  10. Serve hot, garnished with a drizzle of olive oil or a sprinkle of fresh herbs if desired.

Notes

For an extra touch, add a drizzle of cream or sprinkle with fresh herbs before serving.
