Serve these sweet, melty, easy braised leeks as a side dish with pork chops or chicken cutlets.
Halve leeks lengthwise (white and light-green parts only); separate layers and rinse well. In a large skillet, melt butter over medium. Add leeks and water; season with coarse salt and ground pepper. Cover and cook at a medium simmer until leeks are very tender (adding more water if necessary), 14 to 16 minutes.
