On World Protein Day 2026, try this Greek lemon chicken with lemony and herby Mediterranean flavours, perfect for dinner. The magic lies in the marinade, which is a combination of fresh lemon juice, extra-virgin olive oil, garlic, and the classic Mediterranean herb combination of dried oregano and thyme. Dijon mustard adds more flavour and helps the marinade cling to the chicken, while salt and black pepper season it perfectly. What makes this recipe particularly foolproof is the use of bone-in, skin-on chicken thighs, which are naturally juicy and flavourful. Unlike chicken breasts, thighs are virtually impossible to overcook in the oven, making them ideal for busy weeknights.
