Here’s how to make a lower-fat and crispy duck breast the easy way. Use a sharp knife to score the duck breast skin in a cross-hatch pattern, trying not to slice the meat underneath. Cook the breast skin-side down in a cast iron skillet on medium heat, until the fat has melted off and the skin has become golden brown and crispy. Place the skillet in a pre-heated 400 degree oven for 15 minutes or until the inside meat is cooked to medium. Slice the breast and serve with sides or over salad.
