• To make these delicious grilled leeks, follow these detailed steps.

Step 1: Prepare the Leeks

• Start by cleaning the leeks.
• Cut off any tough dark green tops and the root ends.
• Slice the leeks in half lengthwise and fan them out to rinse under cold water, removing any sand or grit.
• Let the leeks dry thoroughly.

Step 2: Preheat the Grill

• While the leeks dry, preheat your grill to medium-high heat. This temperature ensures that the leeks cook evenly and begin to caramelize.

Step 3: Season the Leeks

• In a small mixing bowl, combine olive oil, salt, and pepper.
• Brush this mixture generously over the leeks to coat them evenly. This oil will enhance the flavor and help with that perfect grill mark.

Step 4: Grill the Leeks

• Place the leeks cut side down on the grill.
• Allow them to cook for about 6 to 8 minutes without moving them. This might seem like a long time, but patience is key here!
• Flip the leeks carefully and grill for another 4 to 6 minutes. They should become tender but not mushy.

Step 5: Prepare the Topping

• While the leeks are on the grill, start preparing the topping.
• In a skillet over medium heat, melt the butter.
• Add the onions and garlic, sautéing until they become translucent.
• Pour in the seafood broth and dry white wine, bringing it to a boil.
• Reduce the heat and let it simmer for about 10 minutes, allowing the flavors to meld.

Step 6: Serve and Enjoy!

• Once the leeks are beautifully charred and tender, take them off the grill. Arrange them on a serving platter, spoon the onion-garlic mixture over the top, and sprinkle with fresh parsley and lemon zest for a burst of freshness.
