Marinate the duck in advance. Ideally, it should sit overnight in the refrigerator. Prepare all the ingredients and grate the orange zest.
Wash and dry the duck carcass. Remove the zest from half the orange using a fine grater. Squeeze the juice out of the same half and add to the zest. Squeeze the garlic there, add salt and pepper. Rub the resulting marinade inside and out of the duck. Leave the duck until morning or at least 4 hours.
Remove the core from the apples and cut the apples into orange cubes, peel and cut into the same pieces. For garnish, chop the peppers and potatoes. Use a paper towel to remove the zest and garlic from the skin of the duck. Prick the duck with a fork where fat accumulates under the skin.
Stuff the duck with oranges and apples and secure the duck skin with toothpicks. Place vegetables in the sleeve and duck on top. Bake first at 180 degrees for one hour and 20 minutes. Cut the sleeve and rub with honey and duck fat and leave for another 20 minutes without the sleeve.
Arrange the whole duck nicely on a large plate. Place roasted vegetables on the sides. Cut orange slices and decorate your duck beautifully. If desired, you can sprinkle with herbs. And the most tender duck with a crispy crust is ready. Such a bright dish will whet anyone's appetite.
