Cook the macaroni according to packet instructions. Drain and put in the base of a large ovenproof dish.
In a large saucepan, melt the butter over a medium heat. Add the flour and whisk, cooking for 2 minutes.
Turn off the heat and gradually add the milk, whisking all of the time.
When you have added all of the milk, turn the heat back on and cook, whisking occasionally, until it thickens. Turn off the heat then add the bay leaves, onion, mustard and 2/3 of the cheese, stirring until the cheese has melted.
Pour the sauce over the macaroni and stir gently to make sure it is well combined. Top with the remaining cheese. Put in the oven for 30-35 minutes until golden and bubbling.
