How do you do it in the oven?
I do it in a heavy pan on the stove top. Even if it doesn’t burn, the entire wall behind the range top and the shelf above gets coated in chicken grease and I have to plan time for cleaning all that after I make it, plus airing out the kitchen. I do know I have to stand there forever, stirring. It goes from perfect to burnt in a flash.

Lay out the chicken skins on a sprayed jelly roll pan or a baking pan (not an edgeless cookie sheet because of the grease that renders out). Sprinkle on whatever seasonings you like. Bake at 400. After about 10 minutes keep checking them. Some pieces crisp up faster than others so take those out and leave in the others. Drain them on a rack or paper towels.
