Season the chicken with salt and pepper, in a bowl mix the finely chopped onion, the tangerine juice, oregano, sweet paprika, the garlic powder and pour over the chicken pieces and marinate the best overnight and cover with film.
In a baking dish previously preheated to 190 degrees, brush the bottom with olive oil and put the drained chicken pieces and put it in the oven.
In a saucepan, pour the juices that we had from the marinade and add half a glass of chicken broth and cook until the mixture is reduced by half, then pour over the chicken and cook for about an hour, brushing the chicken from time to time.
Finally put the grill position and brown to taste. Accompany with white rice or French fries and a good salad.
