½ bunch cilantro, stems removed, roughly chopped (plus more for garnish)
Directions
Preheat oven to 450 F.
Soak the wooden cooking plank in water, covering it with something heavy so it stays fully submerged, for at least 30 minutes.
In a medium bowl, mix the crème fraîche, lime zest, and salt to taste.
Add the chicken to the crème fraîche mixture and coat well. Cover and leave to marinate at room temperature for 30 minutes or overnight in the refrigerator. (If making ahead of time, remove the chicken from the fridge to bring it to room temperature before cooking.)
In a small bowl, combine the cilantro and lime juice with a large pinch of salt. Whisk together, taste for seasoning, and set aside.
Add the marinated chicken directly on top of the cooking plank. Reduce the oven temperature to 400 F and bake for 8 minutes on the middle rack, with a sheet pan placed underneath to catch any drippings. Watch closely and spray the plank with water if any flames appear.
Broil for an additional 6-8 minutes, depending on the thickness of the chicken and your desired doneness. Continue to watch the plank closely for flames.
Remove the plank from the oven and allow the chicken to rest for 5 minutes. Drizzle with cilantro lime sauce, garnish with additional fresh cilantro, and serve.
