How to make
Saute sliced onion for 2-3 minutes. Wipe the legs and dust them in the flour. Shake them to drop excess flour. Remove the onions from the pan and put them in a clay pot.
In the same oil fry the thighs until browned on all sides. Preheat oven to 360°F (180°C). Put the fried onions on the legs. Spread chopped potatoes around them, along with tomatoes and celery. Sprinkle with parsley and thyme.
Bake in a tightly closed container for about 45 minutes. Then remove the dish from the stove and pour over the legs with a mixture of broth, corn starch, salt and black pepper.
Return to the oven and bake for another 15-20 minutes.
