3-Ingredient Lemony Green Beans with Frizzled Leeks

This vibrant vegan side dish elevates the humble green bean into something truly special. The combination of blanched haricots verts tossed in a bright citrus dressing and topped with golden, crispy leeks provides a sophisticated contrast of textures. It is a fresh, zesty accompaniment that works beautifully alongside a Sunday roast or as part of a festive spread, offering a lighter alternative to heavier vegetable bakes.

Simplicity is at the heart of this recipe, focusing on high-quality ingredients and precise techniques like blanching to preserve the beans' snap and vivid colour. For those who enjoy a bit of forward planning, the beans can be blanched a day in advance and kept in the fridge, making this an ideal choice for stress-free entertaining. Serve it warm to fully appreciate the fragrant lemon oil and the savoury crunch of the leek matchsticks.

Ingredients for 3-Ingredient Lemony Green Beans with Frizzled Leeks

  • 1.1kg green beans, preferably haricot verts, trimmed

  • 1 teaspoon kosher salt, plus more

  • 3 lemons

  • 2 large leeks, white and light-green parts only

  • 350ml olive oil

  • 1/2 teaspoons freshly ground black pepper

Cook green beans in a large pot of boiling salted water until crisp-tender, 5–7 minutes. Drain, then immediately transfer to a large bowl filled with ice water. Drain again and pat dry.

Meanwhile, zest lemons to yield 1 tablespoon zest. Juice lemons to yield 60ml juice, then slice any remaining lemons into wedges. Cut leeks crosswise into 4" sections, then thinly slice lengthwise into matchsticks.

Heat oil in a large deep-sided skillet over medium-high until shimmering. Cook half of leeks, stirring occasionally, until lightly golden brown and crispy, about 5 minutes. Using a slotted spoon, transfer to paper towels; season with salt. Repeat with remaining leeks; reserve oil in skillet.

Cook green beans, pepper, lemon zest, and remaining 1 teaspoon salt in reserved oil over medium heat, tossing occasionally, just until warmed through, about 5 minutes. Add lemon juice and toss to coat, then transfer to a platter. Drizzle about 120ml oil from pan over; reserve remaining oil for another use. Top with leeks and serve with lemon wedges alongside.

Green beans can be blanched 1 day ahead; let dry, then transfer to an airtight container and chill.
