This easy-to-follow recipe will teach you step-by-step how to make perfect, melt in your mouth roasted leeks with olive oil, garlic, thyme and rosemary.

I’m not sure there’s a vegetable dish that is easier to make or more delicious to eat than roasted leeks. The magic is in it’s simplicity. Just a few simple ingredients, roasted to perfection–trust me, you’ll be making this one again and again.
Leeks taste like a mild, more delicate version of an onion, with the same base flavor but far less sharp intensity. They are far sweeter than other member of the “allium” family like garlic, chives, shallots, and onion. When roasted, hearty leeks become buttery and melt in your mouth tender. The edges get crispy and caramelized too!

Ingredients You’ll Need
Here’s everything you need to make this recipe: leeks, butter, olive oil, garlic, rosemary and thyme.
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.
Recipe Steps:
Step 1. Season
Place the halved leeks in a baking dish or onto a sheet tray. Drizzle with olive oil and season each leek with salt and pepper. Scatter the thyme, rosemary, garlic and butter evenly across the leeks.
Step 2. Roast
Bake in a preheated 425F oven until soft and tender.
Step 3. Serve
Transfer the leeks to a platter and serve warm.
