Season the chicken thighs generously with salt and pepper.
Heat a large frying pan/skillet over medium heat. Add the chicken thighs, skin-side down, while the pan is still cold. Allow to cook for 7-10 minutes until the skin is crisp and deeply golden. Flip the thighs over and cook for another 7-10 minutes until the chicken thighs are fully cooked. The thighs are done when the meat is white through to the bone or the temperature reads 75°C/165°F on a meat thermometer. Remove the thighs from the pan and set aside.
Add the butter, garlic and thyme to the pan and cook for 30 seconds. Add the wine or stock and using a wooden spoon, scrape the sticky bits from the bottom of the pan. Pour in the cream and lemon juice.
Allow the sauce to simmer for 5 minutes or until it coats the back of a spoon easily. Add the Parmesan cheese, stir in then add the chicken thighs. Allow to simmer for 5 minutes then sprinkle with parsley and serve.
