Leeks

Milder than onions, sweeter than shallots — the allium that brings quiet depth to anything it touches.

Store in

Fridge unwashed, loosely wrapped

Keeps for

Up to 2 weeks don't store cut leeks uncovered

Best eaten

Braised or slowly sautéed until silky

Prep tip

Rinse in water soil hides between the layers

Leeks are a long-season allium grown at Cold Springs Organics from early spring through late fall. Cylindrical, white at the base and darkening to green at the top, they bring a mild, sweet onion depth to soups, gratins, and braises without the sharpness of raw onion. Only the white and pale green parts are typically cooked; the tough dark green tops go to the stock pot.

Refrigerate unwashed and loosely wrapped in the crisper drawer for up to 2 weeks. Do not store cut leeks uncovered in the fridge — the smell transfers readily to other foods. Wrap cut leeks tightly in plastic or beeswax wrap and use within a few days.

Trim off the root base and the dark green upper tops (save the tops for homemade stock). Slice the white and pale green section into rounds or half-moons.

Leeks trap soil and grit between their many layers. The best method for cleaning sliced leeks: place in a large bowl of cold water, swish well, and lift the leeks out with your hands — the dirt sinks to the bottom and the clean leeks float up. Repeat if needed.

  • Braised — halve leeks lengthwise, place cut-side down in a wide pan with butter and a splash of broth or wine, cover and cook over low heat for 15–20 minutes until completely silky.
  • Potato-leek soup — sauté sliced leeks in butter until soft and sweet, about 10 minutes; add diced potato and enough broth to cover; simmer until the potato is tender; blend until creamy.
  • Gratin — layer softened leeks in a baking dish with heavy cream and grated gruyère; bake at 375°F (190°C) until bubbling and golden on top.

Buttered leeks on toast — slice leeks and cook slowly in a generous amount of butter over medium-low heat, stirring occasionally, for 15–20 minutes until completely soft, golden, and sweet. Season with salt, pepper, and a pinch of fresh thyme. Pile onto thick toast. Add a poached egg if you’d like a more substantial meal.
