Step 1

Trim the leeks of the dark green tops, leaving only the white and light green parts. Halve them lengthwise, leaving the root end intact. Place in a large bowl of water and swish around to remove dirt from the layers. Leave in the water for up to 15 minutes, then remove and drain on paper towels.

Step 2

Heat a 12 inch skillet that has a lid over medium high heat (See note). Add two tablespoons of butter. When melted, sprinkle sugar, 1/4 teaspoon of salt and pepper evenly over the bottom of the skillet. Add the leeks, cut side down in a single layer. Cook until getting golden brown and caramelized, about 5 minutes.

Step 3

Add wine, broth and thyme. Reduce heat to low, cover and simmer for 10-15 minutes. Leeks are done when easily pierced with a knife.

Step 4

Remove leeks from pan and cover. simmer remaining liquid over medium high heat until thickened, 1-2 minutes. stir in remaining 1 tablespoon of butter and lemon juice. Taste sauce and add salt and pepper if needed. Spoon sauce over leeks and serve.
