Grilled Thai Chicken Breasts With Herb-Lemongrass Crust

The scent of lemongrass always takes me back to my little Bangkok cooking class. It was a sweltering afternoon, and I was clumsily trying to wield a cleaver like a seasoned pro. The instructor, a tiny woman with hands that moved like lightning, patiently guided me through prepping lemongrass stalks. That day, we made a vibrant green curry paste from scratch, and the distinct citrusy aroma of lemongrass was the star. This recipe captures that same bright, bold flavor and brings it to your backyard grill.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 10-12 minutes
• Total Time: 2 hours 20 minutes (includes marinating)
• Servings: 6
• Dietary Type: Dairy-Free

Ingredients

• 1 1⁄2 cups chopped fresh cilantro, divided (leaves and tender stems)
• 3⁄4 cup coconut milk
• 1⁄4 cup finely chopped lemongrass (from about 2 stalks)
• 12 fresh basil leaves, minced
• 3 Thai bird chiles, 2 jalapenos or 2 medium serranos, stemmed, seeded, and finely chopped
• 3 garlic cloves, minced
• 1 1⁄2 tablespoons kosher salt
• 2 teaspoons light brown sugar, packed
• 1 1⁄2 teaspoons fresh ground black pepper
• 3⁄4 teaspoon ground coriander
• 12 boneless skinless chicken breast halves (5 to 5-1/2 lb.)
• 2 limes, cut into wedges for serving

Equipment Needed

• Food processor or blender
• Nonreactive baking dish or container
• Gas grill or charcoal grill

Instructions

1. In a food processor or blender, combine 1-1/4 cups of the chopped fresh cilantro with the coconut milk, finely chopped lemongrass, minced fresh basil leaves, stemmed, seeded, and finely chopped chiles (Thai bird, jalapeno or serrano), minced garlic cloves, kosher salt, packed light brown sugar, fresh ground black pepper, and ground coriander. Purée the mixture until smooth, creating a vibrant green marinade.

2. Arrange the boneless skinless chicken breast halves in a nonreactive baking dish or container that is large enough to accommodate them in a snug single layer. Pour the prepared marinade over the chicken breasts, ensuring they are well coated. Turn the breasts to ensure even coverage. Cover the dish tightly and refrigerate for a minimum of 2 hours, or ideally, up to 1 day. This marinating time allows the flavors to deeply penetrate the chicken.

3. Heat a gas grill to medium-high heat, or prepare a medium-hot charcoal fire. Make sure the grates are clean to prevent sticking. If using a gas grill, ensure all burners are preheated evenly for consistent cooking.

4. Carefully place the marinated chicken breasts on the hot grill. If using a gas grill, keep the grill covered during cooking to maintain a consistent temperature and prevent flare-ups. Grill the chicken for 4 to 5 minutes on the first side, allowing the surface to develop good grill marks. Don’t move the chicken around too much during this time, as this helps with the formation of those desirable grill marks.

5. Flip the chicken breasts, re-covering the grill (if using a gas grill). Continue cooking for an additional 5 to 6 minutes, or until the chicken is firm to the touch and completely cooked through. To ensure doneness, make a small slice into the thickest part of one of the breasts; the juices should run clear, and the meat should be opaque throughout. An internal temperature of 165°F (74°C) is recommended for safe consumption.

6. Once the chicken is fully cooked, transfer it to a platter. Let the grilled chicken rest for 5 minutes before serving. This allows the juices to redistribute, resulting in a more tender and flavorful final product.

7. Sprinkle the rested grilled chicken with the remaining 1/4 cup of fresh chopped cilantro. Serve immediately with lime wedges on the side for squeezing, allowing guests to add a final burst of acidity to balance the richness of the marinade.

Expert Tips & Tricks

• Lemongrass Prep: Don’t skip trimming your lemongrass. Cut off the spiky green top and a portion of the bottom to remove the woody core. Peel back a few of the tougher outer layers to reveal the more tender heart of the stalk.
• Spice Level: If you’re sensitive to heat, start with one chile pepper and adjust to taste. Remember that the seeds contain most of the heat, so removing them will help mellow the spice.
• Even Cooking: Pounding the chicken breasts to an even thickness before marinating ensures they cook at the same rate on the grill, preventing some pieces from drying out while others are undercooked.
• Marinade Magic: For the most flavorful results, marinate the chicken for the full 24 hours. If you’re short on time, even a 2-hour marinade will make a noticeable difference.

Serving & Storage Suggestions

Serve these grilled Thai chicken breasts hot off the grill for the best flavor and texture. The bright, herbaceous marinade pairs wonderfully with a simple side of steamed jasmine rice or a refreshing cucumber salad. For a more substantial meal, consider serving the chicken with grilled vegetables like bell peppers, zucchini, and red onion.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the chicken in a skillet over medium heat, or in a microwave. If reheating in the microwave, add a splash of water or broth to prevent it from drying out. The chicken is also delicious cold, sliced on top of a green salad or in a sandwich.

Variations & Substitutions

• Gluten-Free: This recipe is naturally gluten-free, but always double-check the labels of your ingredients to ensure they are certified gluten-free if you have a severe allergy.
• Spicier Version: For an extra kick, add a pinch of cayenne pepper to the marinade, or use hotter varieties of chiles like Scotch bonnets.

FAQs (Frequently Asked Questions)

Q: Can I use dried herbs if I don’t have fresh cilantro and basil?
A: Fresh herbs provide the best flavor, but in a pinch, you can substitute dried. Use about 1 teaspoon of dried cilantro and 1 teaspoon of dried basil for every tablespoon of fresh.

Q: Can I marinate the chicken for longer than 24 hours?
A: While a longer marinade can enhance the flavor, marinating for too long can cause the chicken to become mushy. It’s best to stick to the 24-hour recommendation.

Q: What if I don’t have a grill?
A: You can bake the chicken in the oven at 375°F (190°C) for about 20-25 minutes, or until cooked through. You can also use a grill pan on the stovetop.

Q: How do I prevent the chicken from sticking to the grill?
A: Make sure your grill grates are clean and well-oiled before placing the chicken on the grill. You can also use a non-stick grill spray.

Q: Can I use chicken thighs instead of chicken breasts?
A: Yes, chicken thighs are a great alternative. They may require a slightly longer cooking time, so be sure to check for doneness.
