Ingredients
Here’s what you’ll need to create this flavorful masterpiece:
- For the Chicken:
- 2 whole chickens (about 1.8 kg each)
- Bamboo skewers
- Charcoal
- Grill
- For the Marinade:
- 4 tablespoons soy sauce
- 1 tablespoon fish sauce
- 2 tablespoons palm sugar
- 1 tablespoon sweet dark soy sauce (or kecap manis)
- 8 tablespoons water
- 4 heads of garlic (30-40 cloves)
- 2 stalks of lemongrass
- 2.5 tablespoons black peppercorns
- 8 coriander roots (or powdered coriander)
- For the Sauce:
- 1.5 tablespoons toasted sticky rice (khao kua)
- 1.5 tablespoons chili flakes
- 1 tablespoon sugar
- 3 tablespoons fish sauce
- 8 tablespoons tamarind juice (adjust to taste)
- Fresh cilantro for garnish
Substitution Options
If some ingredients are hard to find, here are some swaps:
- Palm sugar: Use brown sugar or coconut sugar.
- Sweet dark soy sauce: Substitute with regular soy sauce mixed with a pinch of molasses.
- Toasted sticky rice: Crushed roasted peanuts can mimic the texture and nuttiness.
- Tamarind juice: Lime juice mixed with a bit of sugar works in a pinch.
Step 1: Prepare the Garlic and Lemongrass
Start by peeling and chopping 4 heads of garlic—yes, it’s a lot, but trust me, it’s worth it! Slice the lemongrass finely and remove the tough outer layers. These aromatics are the heart of the marinade, so take your time. As you work, your kitchen will start to smell amazing, like a tropical garden mixed with savory goodness.
Step 2: Crush the Marinade Ingredients
Grab your mortar and pestle (or a blender if you’re short on time) and crush the garlic, lemongrass, black peppercorns, and coriander roots into a coarse paste. The goal is to release all those essential oils and flavors. Pro tip: If using a blender, add a splash of water to help it blend smoothly.
Step 3: Mix the Marinade
In a bowl, combine the crushed paste with soy sauce, fish sauce, palm sugar, sweet soy sauce, and water. Stir until the sugar dissolves, and you have a thick, fragrant marinade. This mixture is like liquid gold—it’s going to transform your chicken into something extraordinary.
Step 4: Prepare the Chicken
If you’re using whole chickens, butterfly them by cutting along the backbone and flattening them. This technique helps the chicken cook evenly and absorb more flavor. It’s a bit messy but totally worth it. Imagine how proud you’ll feel when you serve perfectly grilled chicken at your next gathering.
Step 5: Marinate the Chicken
Place the chicken in a large bowl or dish and generously rub the marinade all over. Make sure every nook and cranny is coated. Cover and let it rest in the fridge overnight—or at least for a few hours. Patience is key here; the longer it marinates, the tastier it gets.
Step 6: Prepare the Charcoal
The next day, light up your charcoal grill. You want a gentle, even heat—not too hot, or the chicken will burn before it’s cooked through. While the coals heat up, take a moment to enjoy the anticipation. Grilling is as much about the process as it is about the result.
Step 7: Grill the Chicken
Place the chicken on the grill and let it cook for about 20 minutes before flipping. Baste it with leftover marinade for extra flavor. Watch as the skin turns golden and crispy, while the inside stays juicy and tender. The smoky aroma is irresistible!
Step 8: Finish and Serve
After about 1.5 hours of slow grilling, your Authentic Thai Chicken is ready. Remove the bamboo skewers, carve the chicken into pieces, and serve with the dipping sauce. Garnish with fresh cilantro for a pop of color.
Chef’s Tip
To enhance the smoky flavor, toss a handful of soaked wood chips onto the charcoal while grilling. It adds an extra layer of authenticity to your Gai Yang.

Necessary Equipment

- Charcoal
- Mortar and pestle (or blender)
- Bamboo skewers
- Sharp knife and cutting board
Storage Tips
If you have leftovers (which is rare!), store them in an airtight container in the fridge for up to 3 days. Reheat gently in the oven to retain moisture. For longer storage, freeze portions in zip-top bags. Thaw overnight in the fridge before reheating.
Proper storage ensures the flavors stay intact. Just imagine pulling out a piece of pre-marinated chicken for a quick weeknight dinner—it’s like having a secret weapon in your freezer.
When reheating, avoid microwaving as it can dry out the chicken. Instead, use a skillet or oven to restore that juicy texture.
Tips and Advice
- Use fresh ingredients whenever possible for the best flavor.
- Don’t rush the marinating process—it’s crucial for developing depth.
- Keep an eye on the grill to prevent burning.
Presentation Ideas
- Serve the chicken on a bed of fresh greens for a vibrant look.
- Garnish with lime wedges and extra cilantro for a pop of color.
- Arrange the pieces neatly on a platter with sticky rice and som tam on the side.
Healthier Alternatives
Here are six ways to make this dish lighter:
- Grilled Chicken Breasts: Use boneless, skinless chicken breasts instead of whole chickens.
- Air Fryer Version: Cook the marinated chicken in an air fryer for less oil.
- Low-Sodium Soy Sauce: Reduce sodium by using a low-sodium option.
- Honey Substitute: Replace palm sugar with honey for a natural sweetener.
- Vegan Option: Try marinating tofu or tempeh for a plant-based twist.
- Spice Control: Adjust the chili flakes to suit milder palates.
Common Mistakes to Avoid
Mistake 1: Overcooking the Chicken
Overcooking is a common issue that leaves the chicken dry and tough. To avoid this, use a meat thermometer to check the internal temperature—it should reach 165°F (74°C). Pro tip: Let the chicken rest for 5-10 minutes after grilling to lock in juices.
Mistake 2: Skipping the Marinating Step
Some folks skip marinating to save time, but this step is essential for infusing flavor. Even a few hours make a big difference. Plan ahead and let the chicken soak up all those delicious spices.
Mistake 3: Using Too Much Heat
High heat burns the outside before the inside cooks properly. Keep the grill at a medium-low temperature for slow, even cooking. Patience pays off here!
