This is a hearty and filling chicken casserole classic from Italy. Cacciatore means "Hunters' Style", so this dish would likely have been what the hunter would eat after a long day out in the forest. It is more usual to cook it with some of the produce of the hunt, perhaps a small hare, pheasant or even wild boar, but perhaps the chicken variety rose in popularity with the hunters who weren't quite so good, and didn't catch anything!
As with most Italian peasant fare, there are probably as many recipes claiming authenticity as there are villages in Italy. Each one will have its individual characteristics and the ingredients may vary in different regions, but the basic recipe is for chicken thighs/drumsticks in a thick tomato sauce enriched with white wine. The rest of the ingredients you can add according to your own taste.
This is a one-pot casserole and is perfect for a cold and wet Autumn afternoon.
