Smashed Twice-Cooked Potatoes with Leeks and Green Garlic

This vegan potato side dish offers a wonderful contrast of textures, combining fluffy centres with irresistibly crisp, golden edges. By steaming the Yukon Gold potatoes before smashing and frying them, you ensure they stay tender while developing a deep, savoury crunch. The addition of seasonal leeks and green garlic provides a mild, aromatic sweetness that perfectly complements the earthy flavour of the potatoes.

Ideal for a weekend roast or as a substantial plant-based side, these smashed twice-cooked potatoes are finished with a bright lift of lemon zest and juice. If you cannot find green garlic, thinly sliced traditional cloves work beautifully as a substitute. Serve them hot from the frying pan with a final drizzle of high-quality olive oil for a simple yet sophisticated addition to your dinner table.

Ingredients for Smashed Twice-Cooked Potatoes with Leeks and Green Garlic

  • 1.1kg medium Yukon Gold potatoes

  • 80ml olive oil, plus more for serving

  • Kosher salt, freshly ground pepper

  • 2 leeks, dark-green parts discarded, cut into 1" pieces

  • 4 green garlic bulbs, white and pale-green parts only, or 2 garlic cloves, thinly sliced

  • 1 teaspoon finely grated lemon zest

  • 1 tablespoon fresh lemon juice

How to make Smashed Twice-Cooked Potatoes with Leeks and Green Garlic

Steam potatoes in a steamer basket in a covered pot filled with 2" water until tender, 15-20 minutes. Transfer potatoes to a plate; let cool. Press with your hand to flatten until skins split and some flesh is exposed (a few may fall apart).

Heat half of 80ml oil in a large skillet over medium-high. Add half of potatoes; season with salt and pepper. Cook, tossing occasionally, until potatoes start to brown, 8-10 minutes. Add half of leeks and garlic; cook, tossing, until potatoes are brown and crisp and leeks are golden and soft, about 4 minutes. Transfer to a large bowl. Repeat with remaining oil, potatoes, leeks, and garlic.

Add lemon zest and juice to potatoes and toss well; season with salt and pepper. Serve drizzled with more oil.
