Ingredients Equipment Method Notes

Ingredients
  

  • 4 large leeks preferably firm, pale green stalks
  • 3 tablespoons extra virgin olive oil good quality for rich flavor
  • 1 teaspoon sea salt to enhance natural sweetness
  • ½ teaspoon freshly cracked black pepper for smoky sharpness
  • 1 dash smoked paprika or dried thyme optional for added depth
  • 1 lemon lemon for fresh brightness

Equipment

  • Rimmed baking sheet
  • Parchment Paper
  • Sharp Knife
  • Basting brush or spoon
  • Lemon squeezer or hand

Method
 

  1. Preheat your oven to 200°C (390°F) and line a rimmed baking sheet with parchment paper for easy cleanup.
  2. Trim the dark green tops and root end from each leek, then slice each in half lengthwise, exposing the tender white interior.
  3. Thoroughly rinse the leeks under cold water to remove any dirt or grit between layers, then pat them dry with a clean towel.
  4. Arrange the leek halves cut-side up on the prepared baking sheet, spacing them evenly to allow for caramelization.
  5. Using a basting brush or spoon, generously drizzle the leeks with olive oil, making sure the cut surfaces are well coated.
  6. Sprinkle the leeks with sea salt, freshly cracked black pepper, and optional smoked paprika or thyme for added flavor.
  7. Place the baking sheet in the oven and roast for 30 to 35 minutes, checking at the 20-minute mark to baste the leeks with any juices that have accumulated.
  8. The leeks are done when they turn a deep golden brown at the edges and feel tender when pierced with a fork, with a slight smoky aroma filling your kitchen.
  9. Remove the leeks from the oven, transfer to a serving plate, and squeeze fresh lemon juice over them to brighten the flavors.
  10. Serve the warm roasted leeks immediately, spooning over any flavorful pan juices and finishing with a sprinkle of herbs if desired.

Notes

For extra smoky flavor, add a dash of smoked paprika before roasting. To keep leeks even more tender, cover with foil during the first 20 minutes, then uncover to finish browning.
