To make the marinade, combine the yoghurt, olive oil, lemon juice and zest, oregano, parsley, paprika, garlic, salt, and pepper.
Mix the chicken in the marinade and refrigerate for a minimum of 20 minutes, but no longer than 24 hours.
Preheat the oven to 190°C or 170°C Fan or 375°F or Gas 5
Arrange the chicken thighs, skin side up, in a baking dish.
Roast for 40-45 minutes, or until the thighs are golden brown and the chicken is cooked through, ideally when the internal temperature reaches 75 °C as measured by a probe thermometer.
