The grated zest of an orange is what makes this marvelous chicken sing.
2 tbs. regular olive oil
12 chicken thighs (bone-in and skin-on)
1 3/4 lbs. chorizo sausage, cut into 1 1/2″ pieces
1 1/4 lbs. baby white potatoes, halved
2 red onions, peeled and roughly chopped
2 tsp. dried oregano
grated zest of 1 orange
Heat the oven to 425°F. Put the oil in a shallow roasting pan and add the chicken, turning to coat and ending up skin-side up. Season well. Nestle in the chorizo and the potatoes, then sprinkle over the onions, oregano and orange zest.
Cook for 1 hours, basting after 30 minutes with the pan juices. If there is not a lot of pan juice, tip in a bit of sherry to de-glaze the pan.
