Slice Leek Bottoms in half lengthwise. Clean Well. Heat Olive Oil in a saute pan over Medium Heat. When hot, add the Leeks. Season both sides with Salt and Pepper. Cook on each side for about 3-5 minutes, until they are both browned and golden.

Add the Garlic, Butter, and Thyme. Once the butter is nice and melted, add the White Wine. Bring to a boil. Cover pan most of the way with lid, leaving a space open for steam. Lower heat to Low and simmer for about 15 minutes. Once leeks are fork tender, remove the lid. Reduce sauce for another few minutes. Serve and top with Chopped Parsley and Parmesan.
