Preheat the oven to 200C/180C Fan/Gas 6. Bring a large pan of salted water to the boil and add the macaroni. Cook for 5 minutes then drain.
Meanwhile trim the leeks, discarding the green parts, then thinly slice. Melt the butter in a large saucepan, add the leeks and cook gently for 5 minutes, or until soft.

Add the pasta to the sauce, stir to combine then pour into a 2 litre/3½ pint ovenproof dish. Sprinkle over the breadcrumbs and bake for 25 minutes until golden-brown.
Towards the end of cooking, bring a pot of water to the boil. Add the peas, cook for 3-4 minutes then drain. Serve the macaroni cheese with the peas.
