Braised Leeks in Butter
Leeks are often treated as mere aromatics, but they have enough character to stand as the centerpiece of a side dish. By cooking them low and slow in butter, you pull out their inherent sweetness without letting them turn into mush.
Clean them thoroughly before you begin
Leeks trap grit between their layers. Slice them, then submerge the pieces in a large bowl of water and agitate them to release the dirt.

What goes in.
- 4 largeleeks, white and light green parts only, halved lengthwise
- 3 tbspunsalted butter
- 1/2 cupchicken or vegetable stock
- 1 tspkosher salt
- 2 sprigsfresh thyme
Manage the Steam
The lid is your most important tool. You are creating an environment where the butter coats the leeks while the steam cooks them from the inside out.
The method.
Prep the leeks
Trim the dark green tops and root ends. Slice lengthwise and rinse under cold running water, fanning out the layers to ensure no grit remains.
Brown the butter
Melt butter in the skillet over medium heat. Once it stops foaming, place the leeks cut-side down.
Sear
Let the leeks sit undisturbed until the cut edges turn a deep golden brown, roughly 5 minutes.
Deglaze and braise
Pour in the stock, add the thyme and salt, and cover with the lid. Reduce heat to low and cook for 10-12 minutes until a paring knife slides through the thickest part without resistance.
Reduce the glaze
Remove the lid and turn the heat back to medium. Let the remaining liquid evaporate until it thickens into a glossy, butter-heavy sauce that coats the leeks.
Other turns to take.
Lemon-Caper Finish
Add a squeeze of fresh lemon juice and a tablespoon of rinsed capers at the very end to cut through the richness of the butter.
Crème Fraîche
Stir in a tablespoon of crème fraîche during the final reduction for a thicker, tangier sauce.
When it doesn't go to plan.
Save the tough dark green tops for your next batch of homemade stock.
If the leeks are very large, quarter them lengthwise instead of halving them to ensure even cooking.
Do not rush the initial sear; that golden color is where most of the depth comes from.
The ones that keep coming up.
How do I know when the leeks are done?
They should be completely tender and translucent. If they still feel firm or fibrous, they need a few more minutes under the lid with a splash more liquid.
Can I use oil instead of butter?
You can, but you will lose the milky sweetness that butter provides. If you must use oil, finish with a small knob of cold butter at the end to emulsify the sauce.
