Cooking the leeks in this way gently softens them without coloring, and releases their allium flavor into the oil. Blending the confit leeks with cream creates a lovely sauce to bring the whole dish together, which could easily stand as a substitute for gravy alongside your choice of protein. If you can’t find puy lentils, then swap them out for other lentils, such as green or beluga. Serve this dish warm or at room temperature, and eat alongside some roasted potatoes, if you like.
