Really you shouldn’t end up with an excess of chicken skin very often. The skin is a delicious and coveted part of fried chicken and roast chicken, and if it’s well-rendered it can also go into some cold, day-after preparations like chicken salad sandwiches.
But if you are shredding leftover chicken to make chicken noodle soup or chicken stew, you may want to set the skin aside for another application.
Here’s how to turn cold, flabby, leftover chicken skin into golden brown, crispy pieces of crackling. Line a sheet tray with parchment and lay out the pieces of chicken skin so they are flat. Place another sheet of parchment on top, and then another sheet tray on top of that, so that you have sandwiched the skin between the trays. This is just to keep the skin from curling up. It may also help them cook evenly, now that I think of it.
Bake in a 350°F oven until crisp and deep golden brown with an amber hue.
You now have what are essentially chicken skin crackers. You may be wondering what you should do with them. Here are some ideas. Crumble them onto soups, and into salads. Use them as a base for an hors d’oeuvre, or as a crispy garnish for any number of dishes. Mac and cheese comes to mind. In my opinion the supreme usage for crispy chicken crackling is to layer it generously onto a tomato sandwich. Spicy chili mayo, pickled red onions, and rocket can play welcome supporting roles in this venture.
