Boil the sprouts in salted water for about 3-4 minutes, then drain.
Heat the oil in an ovenproof frying pan and fry the sprouts along with the herbs and garlic for 1-2 minutes. Transfer the pan to the oven and continue to cook for 10-12 minutes, or until the sprouts are tender.
Serve in a gratin dish.
