Preheat the oven to 190°C.

Cut the leeks into rounds, finely chop the parsley and finely grate the garlic clove.

Combine the breadcrumbs, parsley and garlic in a bowl. Season with salt and pepper and a glug of oil. Stir vigorously to distribute the oil and garlic.

Add the pancetta to a saucepan with a glug of oil, cook over a medium heat for 5 mins until the fat has started to render and the pancetta is starting to crisp.

Remove from the pan and add the leeks, sweat with a pinch of salt for 5 mins until soft but still bright green. Remove from the pan.

Now, add 50ml of olive oil and the flour to the pan. Cook out for 2 mins then slowly add the Arla Lactofree Milk, whisking constantly. Bring to a boil then lower the heat.

Coarsely grate the Arla Lactofree Mature Cheddar Cheese and whisk into the sauce.

Season with salt, pepper and freshly grated nutmeg.

Cook your pasta for 8 mins until just al dente. Drain, reserving a mugful of pasta water. Combine the cooked pasta with the sauce, sweated leeks and pancetta and stir together, adding pasta water until you have a loose sauce.

Pour the lot into a baking dish and top with the garlicky breadcrumbs.
