Preheat your oven to 375°F (190°C). Arrange the thin lemon slices evenly across the bottom of a large roasting pan. This layer creates a fragrant base that flavors everything above it.
Trim the leeks to use only the white and light green parts. Slice them thinly and rinse well under cold water to remove any grit. Spread the leeks evenly over the lemon slices.
Pat the chicken dry with paper towels to help it brown properly. Season both sides generously with salt and freshly ground black pepper. Place the chicken pieces on top of the leek and lemon bed.
Scatter the whole garlic cloves around the chicken pieces. Pour the white wine and fresh lemon juice into the pan, avoiding pouring directly over the chicken skin. This keeps the seasoning intact.
Place the roasting pan in the oven and bake for about 45 minutes. Every 15–20 minutes, spoon some of the pan juices over the chicken to keep it moist and flavorful. Add a little more wine if the pan becomes too dry.
Once the chicken is golden and cooked through, remove it from the oven. Let it rest for a few minutes so the juices redistribute evenly. This ensures every bite stays tender and juicy
