Cooking en papillote involves placing food in a packet of parchment paper, then baking it in the oven. The technique, like stovetop steaming, allows you cook foods sans fats or oils. All you need is parchment paper, a baking sheet, and the foods you'd like to cook. Here, watch Martha make a delicious meal with chicken, asparagus, olives, and artichoke hearts. #chickenrecipe #weeknightdinner
