Chicken (quarters or thighs or portions on the bone work best but I used breast fillets today as that is what I had), streaky bacon, shallots/onions, garlic, mushrooms, dash of brandy, a bit of white wine, stock, tomatoes (tinned or paste/puree) and herbs - fry up the bacon and brown the chicken, fry the veggies in the fat from that (with a bit of butter if more fat is needed), add the brandy and white wine and let it cook off a bit, add the tomatoes/tomato puree and stock and simmer until the chicken is cooked through. You can do it on the hob from start to finish or brown the chicken/bacon and veg on the hob then finish in the oven.
Tarragon and/or parsley are traditional herbs for the French dish.
It is closely related to the Italian version, Chicken Cacciatore - add peppers and olives, use pancetta instead of streaky bacon, and oregano/basil as the herbs.
Both are delicious variations on the same theme and like a lot of traditional peasant dishes you can vary the ingredients a bit depending upon what is available - so you could make with game instead of chicken or add sausage.
