Combine the minced chicken with the garlic, onion, breadcrumbs, dried thyme, rosemary and salt, then mix it all together.
Form the mix into 10 meatballs; slightly damp hands help prevent the mix from sticking to you. You can make the meatballs in advance and keep them in the fridge for up to 24 hours; it helps stabilise them, but it is not necessary.
Drizzle the meatballs with the oil and roll them around to coat them, then place them on a baking tray and drop them in the oven at 220°C or 435°F for 12-15 minutes. Alternatively, place them in an air fryer and cook them at 200°C or 400°F for 10-12 minutes.
Heat a 30cm or 12" frying pan or skillet over a medium heat and add the chicken stock, honey, English mustard and bring it to a simmer.
Add creme fraiche and stir to form a sauce, reduce the heat to low and simmer.
Transfer the meatballs to the pan with the sauce and roll them around to coat them in the sauce.
Add a lid and cook for a final 5-7 minutes before adding the parsley and serving. Check that the meatballs have reached 73°C or 165°F before serving.
