Yogurt-Marinated Chicken Souvlaki (Souvlaki Kotopoulo me Giaourti)

Chicken breast is genuinely prone to drying out on a hot grill, and marinating it in thick yogurt beforehand is one of the most reliable ways to head that off. The yogurt's mild acidity and its proteins work on the meat's surface gently over time, tenderising it and helping it hold moisture through a hard, fast grill in a way a plain oil marinade cannot manage on its own.

This version leans on the same lemon, garlic and oregano that flavour most Greek grilled meat, but the yogurt base changes both the texture of the finished chicken and gives the marinade a thickness that clings to the meat properly rather than running off, coating every side as it grills.

It is genuinely simple, quick weeknight food once the marinating time has passed, needing only good charcoal or a hot grill pan and the same short, attentive cooking any souvlaki wants.

Key preparation steps

1. Cut chicken breast or thigh into even cubes.
2. Marinate in yogurt, lemon, garlic and oregano for at least two hours.
3. Thread onto skewers and grill hard and fast.
4. Rest briefly before serving with pita and salad.

Why yogurt works as a marinade

Yogurt is milder and gentler than a straight acid marinade like pure lemon juice or vinegar, which can toughen meat's surface if left too long. Its enzymes and mild acidity tenderise gradually and evenly, and its thickness means the marinade actually coats and clings to the chicken rather than pooling in the bottom of the bowl.

Chicken thigh, with more fat than breast, is slightly more forgiving here and stays juicier even without the yogurt's help, but breast benefits from this treatment considerably more, which is worth keeping in mind when choosing your cut.

Marinating time

Two hours is a reasonable minimum, and up to overnight in the fridge gives a deeper flavour and more thoroughly tenderised result. Much beyond twenty-four hours and the texture can start to turn slightly mushy, so there is a real upper limit even with a gentle marinade like yogurt.

Grilling

Thread the marinated chicken onto skewers, shaking off any excess marinade so it does not drip and flare on the coals, and grill over genuinely hot heat, turning regularly, for around ten to twelve minutes, until charred in places and cooked through. The yogurt coating chars attractively rather than burning immediately the way a purely oil-based marinade sometimes does.
