When I cook spatch-cock chicken I always use the drip pan lined with foil.
Dome temp between 350-400
cook skin up for 100% of the cook.
cook for about 2hrs or so.
skin is always crispy - note: do not cover the chicken when you take it off, this will cause the skin to get soft.
I'm sure you know how this ended. See the photo. Where are the other food groups?! Where is the balance?! I need a sponsor - someone to call in moments of weakness.
