Rinse and pat the haddock dry using paper towels. Season with salt and pepper.
In a medium bowl, stir together the lemon juice, olive oil, garlic and herbs.
Place a haddock fillet skin-side down atop a sheet of foil. Wrap the ends of the foil to form a spiral shape. Spoon the lemon mixture over the fish and fold the aluminum foil over the haddock so it is completely covered and closed.
Place foil packs with fish on grill. Cook for about 8-10 minutes or until the fish is done.
Notes
Use wild haddock when possible. It is healthier for you and just tastes better. Frozen haddock works fine too but just make sure they're thawed before cooking.
While store-bought bottles can be quite convenient, they lack in flavor compared to the real thing. It really isn’t that much extra work to freshly squeeze the lemons and you’ll notice a difference in flavor.
If using a pellet grill, use a mild wood for a subtle smoke flavor like alder, apple or cherry.
If not using aluminum foil, coat the grill grates with oil and cook for 1-2 minutes longer.
