Ingredients You’ll Need
The beauty of this Thai Grilled Chicken (Gai Yang) Recipe lies in its simplicity, yet each ingredient plays a vital role in creating its unforgettable taste and texture. From the fragrant lemongrass to the perfectly balanced soy and fish sauces, every element works harmoniously to elevate this dish from ordinary to extraordinary.
- 2 lb / 1 kg chicken thigh fillets (skinless, boneless): Tender and juicy, thigh meat is the ideal choice for grilling to retain moisture and flavor.
- 1 large lemongrass stalk (white part only, sliced 5mm thick): This adds an aromatic citrusy note that brightens the marinade beautifully; use paste if fresh is unavailable.
- 4 cloves garlic (peeled): Essential for infusing pungent, savory depth into the marinade.
- 2 1/2 tbsp fish sauce: The salty umami backbone of the dish, providing authentic Thai flavor complexity.
- 1 tbsp light soy sauce (or tamari): Adds a gentle saltiness and rich color without overwhelming the chicken.
- 2 tsp dark soy sauce: Offers a deeper, slightly sweet flavor and a beautiful caramelized finish when grilled.
- 3 tbsp brown sugar or palm sugar (tightly packed): Balances savory notes with a subtle sweetness that caramelizes deliciously on the grill.
- 2 tbsp oil (vegetable or neutral): Helps to coat the chicken for even cooking and prevents sticking, while keeping flavors melded.
- Nam Jim Jaew (traditional Thai dipping sauce): A must-have for dipping, this sauce adds a tangy, spicy kick that complements the chicken perfectly.
- Lime wedges: For fresh, zesty brightness when serving.
- Red chili (finely sliced, optional): Adds an extra punch of heat and vibrant color.
- Cilantro/coriander leaves (optional): A fresh herbal garnish that enhances the dish’s freshness.
- Coconut rice: The perfect fragrant side to soak up all the delicious juices and balance the smoky chicken.
How to Make Thai Grilled Chicken (Gai Yang) Recipe
Step 1: Blitz the Marinade
Start by placing all the marinade ingredients except the oil into a jug just big enough to fit the head of your stick blender. Blitz everything until the lemongrass and garlic are completely pureed, creating a fragrant, aromatic base. Don’t worry if you don’t have a stick blender — simply finely grate the lemongrass and garlic and mix everything well. This step is crucial because it ensures every piece of chicken will soak up incredible flavor.
Step 2: Marinate the Chicken
Transfer the pureed marinade to a bowl, then stir in the oil to help the flavors coat the chicken evenly. Add your chicken thigh fillets and toss until each piece is thoroughly coated in the marinade. Cover and refrigerate overnight if possible for best results — though a minimum of 3 hours will still produce deliciously tender and flavorful chicken. If you’re short on time, thinly slice the chicken and toss it in the marinade before cooking it as a stir-fry instead.
Step 3: Prepare to Cook
Fire up your outdoor BBQ grill to high heat — the high temperature will give the chicken that lovely smoky char — or use a non-stick pan on the stove set to high to achieve similar results. Preheating is important so the chicken sizzles the moment it hits the grill or pan, locking in those delicious juices.
Step 4: Grill the Chicken
Remove the chicken from the marinade, discarding the leftover marinade as it can burn easily. Place the chicken on the grill or in the pan, then turn the heat down to medium. The marinade’s sugar content tends to burn quickly, so moderate heat helps achieve that perfect caramelized exterior. Cook for around 5 to 6 minutes on each side until golden brown and cooked through. If you notice any burning, flip the chicken immediately — don’t hesitate to flip it multiple times to avoid charring while cooking evenly.
Step 5: Rest and Serve
Once cooked, let the chicken rest for about 3 minutes to allow the juices to redistribute, keeping the meat juicy and tender. Serve it with a generous mound of steamy coconut rice, fresh lime wedges, and garnish with red chilies and cilantro if you like. Don’t forget to add your favorite dipping sauce on the side to complete this irresistible meal!

Garnishes
The vibrant, fresh garnishes truly elevate this Thai Grilled Chicken (Gai Yang) Recipe. Thinly sliced red chilli adds a beautiful pop of color and a little extra heat, while fresh cilantro leaves bring a cool, herbal brightness that contrasts wonderfully with the smoky chicken. Lime wedges are essential, adding a lively acidity that cuts through the richness and adds the perfect finishing touch.
Side Dishes
Coconut rice is the classic accompaniment for Gai Yang and is perfect for soaking up every flavorful drip from the grilled chicken. The subtle sweetness and creamy texture of coconut rice balance the savory, smoky chicken beautifully. You can also add a simple green papaya salad or a crisp cucumber salad for some refreshing crunch and texture contrast alongside the meal.
Creative Ways to Present
For a fun twist, try serving the chicken sliced and stacked like a tower on top of a bed of fragrant coconut rice, drizzled with your favorite dipping sauce. Alternatively, serve the chicken pieces on skewers for easy finger food at a party, accompanied by small bowls of Nam Jim Jaew and lime wedges for guests to customize each bite. The colorful garnishes and sauces make the platter visually stunning and very inviting.
Make Ahead and Storage
Storing Leftovers
Leftover Thai Grilled Chicken (Gai Yang) Recipe keeps beautifully in an airtight container in the refrigerator for up to 3 days. Store with any extra sauce separately to maintain the ideal texture. When refrigerated properly, the chicken remains tender and flavorful, making it perfect for a quick lunch or dinner the next day.
Freezing
You can freeze cooked chicken for up to 2 months. Wrap the pieces tightly in plastic wrap and then place them in a freezer-safe container or zip-lock bag to avoid freezer burn. This way, you’ll have ready-to-reheat deliciousness on hand whenever you crave the vibrant flavors of Gai Yang.
Reheating
To reheat, gently warm the chicken in a low oven or covered skillet over medium heat to avoid drying out the meat. Adding a splash of water or chicken stock while reheating can help maintain moisture. Avoid microwave reheating if possible, as it tends to make chicken tough and unevenly heated.
FAQs
Can I use chicken breast instead of thigh fillets?
Yes, you can use chicken breast, but thigh meat is preferred because it stays juicier and has more flavor when grilled. Breasts tend to dry out faster, so watch cooking time carefully if you substitute.
Is it necessary to marinate overnight?
While overnight marinating delivers the best depth of flavor and tenderness, a minimum of 3 hours will still produce delicious results. In a pinch, even 30 minutes is better than nothing!
What if I don’t have fresh lemongrass?
Using lemongrass paste is a great substitute and quite common in many Thai kitchens. Just adjust quantity to taste since the paste can be more concentrated than fresh stalks.
Can I cook this chicken indoors instead of on a grill?
Absolutely! A hot non-stick pan or grill pan on the stove will work well. Just be sure to watch for burning due to the sugar content in the marinade and adjust heat as needed.
What sauces go best with Thai Grilled Chicken (Gai Yang) Recipe?
Nam Jim Jaew, a spicy and tangy Thai dipping sauce, is the classic accompaniment. Lime sweet chili sauce or traditional sweet chili sauce also pair beautifully if you prefer milder or sweeter sauces.

Ingredients

- Lime sweet chili sauce
- Sweet chili sauce (bottle)
- Lime wedges
- Red chili, finely sliced (optional)
- Cilantro/coriander leaves (optional)
- Coconut rice
Instructions
- Blitz: Place all marinade ingredients except for the oil into a jug just large enough to fit the head of a stick blender. Blitz until the lemongrass and garlic are fully pureed. If you don’t have a stick blender, finely grate the lemongrass and garlic, then mix thoroughly.
- Marinate: Pour the pureed marinade into a bowl, add oil, and stir well. Add the chicken thigh fillets and toss until they are thoroughly coated with the marinade. Cover and marinate overnight for best flavor, though a minimum of 3 hours is acceptable. If short on time, finely slice the chicken, toss in the marinade, and cook like a stir-fry.
- Heat the grill or pan: Preheat your outdoor BBQ grill to high heat or heat a non-stick pan over high heat on the stove.
- Cook: Remove the chicken from the marinade, discarding the excess marinade (unless baking in the oven, see note 3). Place the chicken on the BBQ or in the hot pan, then reduce the heat to medium to prevent burning due to the sugar content in the marinade. Cook the chicken for about 5 to 6 minutes on each side until golden brown and cooked through. If the chicken begins to burn, flip it immediately and continue flipping as needed.
- Rest and serve: Let the chicken rest for 3 minutes after cooking. Serve alongside a generous mound of steamy coconut rice, lime wedges, fresh sliced red chilies, and coriander/cilantro leaves. Accompany with your chosen dipping sauce such as Nam Jim Jaew or sweet chili sauce for an authentic Thai experience.
Notes
- Note 1: Using skinless, boneless chicken thigh fillets ensures juicy, tender meat without extra fat.
- Note 2: If you can’t find fresh lemongrass, substitute with 1 tbsp lemongrass paste for convenience.
- Note 3: If baking instead of grilling or pan-frying, you can retain the marinade to baste the chicken during cooking. However, discard marinade when grilling or pan-frying for food safety.
- The marinade is sweet and can burn easily, so monitor the cooking temperature carefully and adjust as needed.
- Marinating overnight deeply infuses flavors, but a minimum of 3 hours still produces good results.
- Serve with coconut rice to complement the aromatic spices and add a creamy, fragrant base to the meal.
