Notes

 
How to Wash and Prep Leeks for Roasting:
Leeks are grown in sandy soil and much of that soil ends up inside the leeks as they grow which is why it's important to wash them thoroughly.
  • Trimming: Trim the roots and dark green parts from the leeks and discard (or save to use for making stock). Halve the leeks lengthwise.
  • Washing: Fill your *clean* kitchen sink with cold water. Place the trimmed leeks in the water, give them a gentle stir or shake to remove any soil or grit between the layers then allow them to soak for a 5-minutes, during that time impurities will fall to the bottom of the sink. After 5-minutes, remove them from the water, give them a final rinse under running water and they're good to go.
 
Storing and Re-heating Leftovers:
  • Leftover roasted leeks can be stored, covered, in the refrigerator for up to 5 days. Reheat in a preheated 350F oven for 5-10 minutes.
