Step 1

Heat oil in a large non-stick frypan over medium heat, add the pancetta and cook for 10 minutes until it starts to crisp.

Step 2

Meanwhile, cook the pasta in a large saucepan of boiling salted water according to packet instructions. Drain.

Step 3

Lightly whisk eggs and cream in a bowl.

Step 4

Add the butter and parsley to pancetta, then add pasta and cheeses and toss well to combine. Remove the pan from the heat and quickly add the cream mixture. Toss gently to combine – the pasta's heat will cook the egg slightly and form a creamy sauce. Season, then serve with extra parmesan and parsley.
