Olive Oil-Roasted Leeks

These olive oil-roasted leeks are a masterclass in how slow cooking can transform a humble vegetable into a luxurious side dish. By gently confitting the leeks in plenty of oil before a final blast of heat, they develop a buttery, melt-in-the-mouth texture and a deep, concentrated sweetness. The outer layers become slightly crisp and golden, while the centres remain wonderfully tender and succulent.

This simple vegan dish is an excellent addition to a Sunday roast or served alongside crusty bread and creamy pulses for a light, plant-based supper. As an added bonus, the leftover infused oil is packed with savoury flavour and makes a fantastic base for homemade salad dressings or for sautéing aromatics in your next soup or stew.

  • 120ml olive oil

  • Sel

How to make Olive Oil-Roasted Leeks

Place a rimmed baking sheet in oven and preheat to 204°C. Cut 6 leeks, white and pale-green parts only, in half lengthwise. Rinse well and pat completely dry. Toss with 120ml olive oil; season with salt. Arrange leeks, cut side down, on hot baking sheet and cover loosely with foil. Reduce oven temperature to 149°C. Bake until leeks are lightly browned on cut sides and very tender, about 1 1/2 hours.

Uncover leeks and turn cut side up. Increase oven temperature to 204°C; roast leeks until golden brown, 15-20 minutes. (Reserve the oil for making vinaigrettes or roasting vegetables. Let cool; cover and chill.)
