Presoak a large unglazed clay pot, top and bottom, in water for 15 minutes.
Brown the ground beef in a frying pan, then discard any fat. Pour the olive oil into the presoaked pot, add a layer of lasagne, and alternate all the other ingredients except the Parmesan cheese, ending with a layer of lasagne. Sprinkle the top with the Parmesan.
Cover the pot and put it in a cold oven.<
