Braised Leeks, Peas, and Lettuce

This vibrant dish of braised leeks, peas and lettuce is a celebration of fresh, seasonal flavours. Inspired by the classic French 'petits pois à la française', this version uses sweet leeks and crisp Little Gem lettuce to create a light yet comforting side dish. The gentle braising technique allows the vegetables to soften into the buttery white wine sauce, while the addition of fresh mint and lemon zest provides a bright, aromatic finish that lifts the entire plate.

As a versatile vegetarian dish, it makes a wonderful accompaniment to roast chicken or poached fish, though it is equally delicious served alongside a crusty loaf of sourdough to soak up the juices. The sprinkling of roasted pistachios adds a sophisticated crunch, making it an elegant choice for a Sunday lunch or a quick midweek meal that feels a little more special.

Ingredients for Braised Leeks, Peas, and Lettuce

  • 4 tablespoons unsalted butter

  • 3 leeks, white and pale green parts only, thinly sliced, well rinsed

  • 1 teaspoon kosher salt, plus more

  • 1 teaspoon kosher salt, plus more

  • 1/2 teaspoons freshly ground black pepper, plus more

  • 1/4 cup dry white wine

  • 2 heads of Little Gem lettuce or cos hearts, thinly sliced

  • 450g frozen peas, thawed

  • 2 tablespoons finely chopped chives

  • 2 tablespoons finely chopped mint

  • 1 teaspoon finely grated lemon zest

  • 30g roasted, salted pistachios, coarsely chopped

Melt butter in a large wide saucepan over medium-low heat. Cook leeks, partially covered and stirring occasionally, until tender but not browned, 5–7 minutes. Season with 1 teaspoon salt and 1/2 teaspoons pepper, then pour in wine. Increase heat to medium-high and continue to cook, stirring occasionally, until wine is reduced by half, 1–2 minutes. Add lettuce, peas, and 1 cup water. Partially cover pan and bring liquid to a simmer. Reduce heat to medium-low to maintain a gentle simmer and cook, stirring occasionally, until lettuce and peas are tender, about 5 minutes.

Remove from heat, then stir in chives, mint, and lemon zest; season with salt and pepper. Transfer to a platter. Top with pistachios.
