How to make
Chop the onions and leeks finely and fry them. Add the rice and shortly thereafter, the diced ham, salt and pepper. Dissolve the broth in 4 cups of warm water and add it too.
Pour the whole mixture into a fireproof glass container, close and roast in a moderate oven. Once it is almost ready, sprinkle it with grated cheese and bake until the cheese melts.
You can boil the risotto with ham in a pot on the stove, while adding the broth gradually.
