Step 1

Heat the oil in a large non-stick frying pan. Add the leeks and 2 tbsp water, and cook for about 10 mins until very soft. Add the bacon, turn up the heat and fry until cooked.

Step 2

Meanwhile, cook the pasta following pack instructions. Drain and reserve a mug of the cooking water.

Step 3

Spoon cheese into the leek and bacon mix, adding some of the reserved cooking water. Season and stir gently over a low heat until melted. Toss through the cooked pasta, adding a little more cooking water, if needed, to help the sauce coat the pasta.
