Gai Yang — Lemongrass Grilled Chicken from Isaan
This Thai grilled chicken recipe — gai yang — marinates bone-in chicken quarters in lemongrass, garlic, coriander root and fish sauce, then grills them slowly over charcoal until the skin is blistered and the meat stays juicy. It is served the Isaan way, with sticky rice and a sharp, sour nam jim jaew dipping sauce. Unlike Thai chicken larb, which is a minced-chicken salad tossed with toasted rice powder and lime, gai yang is a whole grilled bird — smoky skin, juicy meat and a dipping sauce, not a salad. One serving is about 370 g.
Gai yang comes from Isaan, the north-eastern region of Thailand, where Lao-influenced cooks grill marinated chicken over charcoal at roadside stalls. The dish travelled south with Isaan migrants and became one of Thailand's best-known street foods. The marinade — lemongrass, garlic, coriander root, fish sauce and palm sugar — is the same aromatic base found across Isaan cooking, and the sticky rice and nam jim jaew are the region's everyday accompaniments.
Pairs well with: Sticky rice, som tam (green papaya salad) and nam jim jaew

Real gai yang is grilled in two stages — hot for the skin, gentle for the meat — and always served with sticky rice and nam jim jaew, never with plain steamed rice alone.
Execution Methodology & Culinary Technique
Prep Stage: Pound the Marinade, Soak the Rice
25 Mins • Pounding & Soaking
Pound the garlic, lemongrass, coriander root and white pepper in a mortar until they form a rough paste, then stir in the fish sauce, soy sauce, palm sugar, turmeric and oil. Rub the paste all over the chicken, working it into the scores, and leave it to marinate for at least 2 hours — overnight is better. Put the sticky rice on to soak at the same time, and stir together the nam jim jaew so its flavours can meld.
Maestro Tip: Pounding the aromatics instead of chopping them releases their oils — a chopped marinade sits on the surface, a pounded one soaks in.
25 Mins Steaming, about 100°C (212°F)
Drain the soaked rice and tip it into a steamer basket lined with muslin. Steam over boiling water for 20–25 minutes, turning the rice once halfway, until the grains are tender, glossy and sticky. Keep it covered and warm in a small basket or bowl.
Turn the rice once so the top and bottom steam evenly — the top stays hard otherwise.
Done when: The grains are tender, glossy and clump together when pressed.
20 Mins Medium heat, about 190°C (375°F)
Heat the grill to medium — charcoal is best, a gas grill works too. Lay the chicken skin-side down and grill for 10 minutes without moving it, until the skin is golden and blistered. Turn and grill the other side for 10 minutes.
Do not press the chicken down: pressing squeezes the juices out and the skin sticks to the grate.
Done when: The skin is golden-brown and blistered, with charred edges in places.
20 Mins Low-medium heat, about 160°C (320°F), chicken to 74°C (165°F)
Move the chicken to the cooler side of the grill, or turn the heat down, and cook for a further 15–20 minutes, turning once, until the thickest part of the thigh reads 74°C (165°F) on a thermometer and the juices run clear when pierced.
Two-stage grilling is the secret: high heat for the skin, gentle heat for the meat — one heat does both badly.
Done when: The thigh reads 74°C (165°F) at its thickest point, and the juices run clear.
10 Mins Rest off the heat, chicken at 74°C (165°F)
Take the chicken off the grill and rest it for 10 minutes, loosely covered. Then cut each quarter through the joint into 3–4 pieces, chopping cleanly through the bone with a heavy knife or cleaver.
Resting lets the juices settle back into the meat — cut too soon and they run out onto the board.
Done when: The meat is juicy all the way through, with no pink at the bone.
2 Mins Serve hot, chicken at 74°C (165°F)
Pile the chicken on a plate, put the sticky rice in a small basket or bowl beside it, and set out the nam jim jaew. Eat by tearing off a ball of sticky rice with your fingers, pinching up a piece of chicken, and dipping both in the sauce.
Serve the sauce in a small bowl on the plate, not poured over the chicken — the crisp skin must stay crisp.
Done when: The chicken is hot, the skin is crisp, and the rice is warm and sticky.
Finishing Touches & Plating
Eat gai yang the Isaan way — with your hands, sticky rice pinched into a ball, chicken dipped in the sharp nam jim jaew. The sauce is not optional; it is half the dish.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.
Vitamins & minerals: Vitamin B6 and niacin (chicken), vitamin C (lime, lemongrass), selenium (chicken), iron (chicken).
High in Protein
About 56 g of protein per serving from the chicken, which helps keep you full long after the meal.
B Vitamins and Selenium
Chicken is a natural source of niacin, vitamin B6 and selenium, which support normal energy metabolism and immune function.
Slow Grilling, Real Flavour
Charcoal grilling renders the fat slowly and lets the lemongrass marinade caramelise on the skin — no deep-frying needed.
Food Pairings
To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:
Sides
Sticky Rice
Sticky rice is the essential partner — its mild, chewy grains soak up the chicken juices and give your fingers something to pinch the meat with.
Vegetables
Som Tam (Green Papaya Salad)
Sharp, sour som tam cuts through the rich grilled skin and resets the palate — gai yang and som tam are the classic Isaan pair.
Sauces
Nam Jim Jaew
The sour, salty, chilli-hot dipping sauce is built for this chicken: its lime and toasted rice cut the fat and echo the marinade's flavours.
Drinks
Iced Thai Tea or Beer
A cold, sweet iced tea or a cold lager cools the mouth after the chilli sauce and the smoky grill.
Full Menus
As an Isaan Street-Food Meal
Serve the chicken with sticky rice and som tam, exactly as the roadside grills of north-east Thailand do — hands, no cutlery, sauce on the side.
Complete menu
Serve the chicken with sticky rice and som tam, with nam jim jaew on the side and iced Thai tea to drink.
Digestive Guardrails
To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:
Grilling Over Fierce Heat Throughout
High heat all the way through burns the skin black before the meat near the bone is cooked — finish on gentle heat and check the temperature. This is general guidance, not medical advice.
Skipping the Rest
Cutting the chicken straight off the grill lets the juices run out onto the board; ten minutes of rest keeps the meat juicy.
