Preheat the oven to 210°C/ 190°C fan/ 410°C.
Add all the Lemon-Garlic sauce ingredients to a jug and blend using a stick blended until combined.
Cut the potatoes into chunky wedges, no need to par boil them for this recipe! Add the chicken thighs and potatoes to a very large, lined baking tray, pour the sauce onto the chicken thighs and mix so the potatoes are coated in some of the sauce too. Drizzle with a little olive oil, add in the thyme, season with a salt and pepper. Bake the traybake for 25 minutes, remove from the oven, flip the potatoes only and baste the chicken, then bake for 20 minutes.
To serve, spread the tzatziki onto a plate, add the chicken and potatoes, spoon over any remaining roasting juices, garnish with the parsley, feta and pink pickled onions. Serve a green salad alongside if you fancy it.
