Thai grilled chicken in this simple version uses boneless thighs marinated with soy sauce, fish sauce, lime, brown sugar, garlic, coriander, and cumin. The finished chicken has a savory-sweet surface with lightly charred edges.
Plan for at least an hour of refrigerator marinating before grilling. The timing below is for four boneless, skinless thighs; thickness and the heat of your grill determine exactly when they are ready.

Why This Recipe Works
Fish sauce and soy sauce season the meat, while lime brings a small amount of acidity and garlic adds depth. Brown sugar helps the surface brown quickly. A grill with both a hot and cooler area lets you build color without letting the sugary marinade burn before the center cooks.
Ingredients
Choose four similarly sized boneless, skinless thighs and open out folded pieces before marinating. Bone-in thighs need a different cooking schedule. Brown sugar should be packed into the measuring spoon. Ground coriander and cumin make this an accessible Thai-inspired marinade rather than a traditional whole-chicken preparation. The measured tablespoon of oil goes into the marinade; have a little additional neutral oil available for the grill grate. Soy and fish sauces bring salt, so extra salt is usually unnecessary.
For the Marinade
- 2 tablespoons soy sauce
- 1 tablespoon fish sauce
- 2 tablespoons brown sugar, packed
- 1 tablespoon lime juice
- 2 cloves garlic, minced
- 1 teaspoon ground coriander
- 1 teaspoon ground cumin
- 1 teaspoon black pepper
- 1 tablespoon vegetable oil, for the marinade
For Grilling
- 4 boneless, skinless chicken thighs, opened out
For Garnish
- fresh cilantro, optional garnish
As Needed
- neutral oil, as needed for the grill grate
How to Make Thai Grilled Chicken
1. Mix a smooth marinade. Whisk soy sauce, fish sauce, brown sugar, lime juice, minced garlic, ground spices, pepper, and the measured oil until the sugar is mostly dissolved. Press out obvious sugar lumps with the whisk. A smooth mixture coats the meat more evenly and prevents pockets of concentrated sugar from catching on the grill.
2. Marinate in the refrigerator. Turn the opened-out thighs through the mixture in a covered container or sealed bag. Refrigerate for at least an hour, or up to twelve hours, turning once when convenient. The recipe includes the minimum hour in its total time. Keep the meat chilled during the wait; bringing raw chicken to room temperature is unnecessary.
3. Manage the grill heat. Heat one area to medium-high, about 375–400°F, and leave a second area cooler. Clean and lightly oil the grate. Let excess marinade drip from the thighs, then discard the used marinade. Grill about six to eight minutes per side, looking for brown edges rather than blackened sugar. Move a piece to the cooler area if its surface darkens faster than its center cooks.
4. Check and rest. Measure the thickest section of each thigh; it must reach 165°F before coming off the grill. Thin edges can finish sooner than folded or thick centers, so check pieces individually. Rest on a clean plate for five minutes before slicing across the grain. The short pause reduces the juice that runs onto the cutting board.
How to Serve
Serve one thigh per portion with steamed jasmine rice and crisp cucumber slices. Spoon the juices from the resting plate over the sliced cooked meat if desired. Cilantro is an optional fresh finish. For a larger spread, offer pad Thai or a simple cabbage salad alongside the chicken.
Storage and Reheating
Refrigerate cooked chicken within two hours in a shallow covered container at 40°F or below. Use within three to four days, or freeze for up to two months. Thaw in the refrigerator before warming. Reheat leftovers to 165°F, adding a small splash of water and covering to reduce drying. Fresh cilantro is best added after warming. See federal cold-storage guidance for refrigerated foods.
Tips and Variations
- Open out folded thighs for even thickness.
- Use a cooler grill area when the sugary coating darkens quickly.
- Discard marinade that has held raw chicken.
- Use a thermometer to check each piece individually.
Frequently Asked Questions
Can I use a grill pan?
Yes, heat it over medium to medium-high and ventilate the kitchen. Lower the heat if the sugar begins to scorch.
Can I use chicken breasts?
Flatten them to an even thickness first. Their timing differs from thighs, so check their centers with a thermometer.
Is this the same as traditional gai yang?
This is a simplified thigh recipe with pantry spices. Traditional versions often use a different marinade and larger bone-in pieces.
Can I omit fish sauce?
Use an equal amount of soy sauce as a practical substitute. It will have a different savory flavor and salt balance.
Can I marinate overnight?
Yes, up to about twelve hours in the refrigerator. Keep the container sealed and chilled.
