In a bowl, mix together the chicken breasts with the herb seasoning, salt and 2 tbsp oil.
Heat the remaining oil in a medium-sized non-stick frying pan set over a medium heat. Once hot, add the chicken breasts (start with the skin side if using skin-on - see notes for a good tip) and cook for 7 minutes on each side - or until golden on the outside and cooked through on the inside. Remove from the pan and leave to rest on a clean chopping board.
Next, cook the pasta in well salted boiling water for 1 minute less than the packet instructions.
Meanwhile, return the pan to a medium heat and add the butter and garlic, stirring to coat in the juices from the pan. Pour in the cream. Stir in most of the Parmesan, keeping some back as a garnish. Add about 60ml of the starchy pasta cooking water and allow the whole thing to bubble gently.
Once the pasta is ready, reserve some of the cooking water in case you need extra for the sauce and drain well.
Add the pasta to the pan and stir everything together so the pasta melds to the sauce to create a deliciously creamy dish. Add a splash of water if you need to and stir and toss the whole thing together to help create a smooth and silky sauce. Taste and adjust the seasoning, as needed. Stir through most of the parsley and add a squeeze of lemon juice (about 1tbsp)
Spoon the pasta into serving bowls. Slice each chicken breast into thick slices and arrange one on top of each bowl. Sprinkle with the remaining Parmesan, parsley and freshly grated lemon zest. Enjoy!
