Preheat the oven to 350 degrees and prepare to salt the duck. To do this, take a fork and puncture the skin slightly all over in order to assist with roasting. After salting the duck, stuff the inside with orange, parsley and garlic.
Roast the duck for 1-1.5 hours in a cast iron skillet to ensure it becomes crispy. Turn the duck midway or once you have achieved a golden brown roast on the initial side. Once cooked to crispy, set aside and let rest.
Begin making your orange sauce in a saucepan on medium to high temperature. Heat the orange marmalade and stir repeatedly until it caramelizes. Add in orange juice, orange zest, white wine, chicken broth, vegan butter and sugar or honey for your sauce. Boil until thoroughly reduced.
Strain the sauce and add in some salt and pepper to taste. Then, begin to baste the sauce all over the cooked duck.
Garnish the plate with orange slices and orange zest.
