Grilled Lemongrass Chicken (Gà Nướng Xả) – A Vietnamese Favorite
Grilled Lemongrass Chicken, known in Vietnamese as Gà Nướng Xả, is one of the most beloved dishes in the cuisine of Vietnam. Fragrant, smoky, slightly sweet, and deeply savory, this dish captures everything people love about Vietnamese food: balance, freshness, and bold yet harmonious flavors. Tender chicken is marinated in finely minced lemongrass, garlic, fish sauce, and sugar, then grilled until caramelized and lightly charred. The result is juicy meat infused with citrusy aroma and irresistible smoky depth.
Whether served over rice, tucked into a bánh mì sandwich, or layered over vermicelli noodles with herbs and pickles, Gà Nướng Xả is versatile, satisfying, and surprisingly simple to prepare at home.
Why Lemongrass Is the Star
Lemongrass (xả in Vietnamese) provides a bright, citrusy fragrance that defines this dish. Unlike lemon, lemongrass offers subtle sweetness and herbal complexity without sharp acidity. When grilled, it releases aromatic oils that perfume the chicken beautifully.
Fresh lemongrass is essential here. Look for firm, pale stalks with fresh green tops. You’ll only use the tender white and light green portions near the base.
Ingredients (Serves 4–6)
For the Chicken:
- 1.5 kg chicken thighs (boneless, skin-on recommended for best flavor)
- 1 tablespoon neutral oil (for grilling)
For the Lemongrass Marinade:
- 3 stalks fresh lemongrass (white part only), very finely minced
- 4 cloves garlic, minced
- 2 shallots, finely chopped
- 3 tablespoons fish sauce
- 2 tablespoons soy sauce
- 2 tablespoons brown sugar
- 1 tablespoon honey
- 1 tablespoon lime juice
- 1 teaspoon freshly ground black pepper
- 1 teaspoon sesame oil (optional)
- ½ teaspoon chili flakes or 1 small red chili (optional)
For Serving:
- Steamed jasmine rice or rice vermicelli
- Pickled carrots and daikon
- Sliced cucumber
- Fresh herbs (mint, cilantro, Thai basil)
- Lime wedges
Step 1: Prepare the Lemongrass
Trim the dry tops and tough outer layers of the lemongrass stalks. Finely mince the tender white portion. The finer you chop it, the better it will blend into the marinade and prevent fibrous bits in the final dish.
Tip: You can pulse lemongrass briefly in a food processor, but avoid over-processing into a paste.
Step 2: Prepare the Chicken
Pat the chicken thighs dry with paper towels. If they are very thick, lightly score the meat side with shallow cuts to help the marinade penetrate deeply.
If using bone-in chicken, extend the grilling time slightly. Boneless thighs cook faster and are easier to slice for serving.
Step 3: Make the Marinade
In a large bowl, combine:
- Minced lemongrass
- Garlic
- Shallots
- Fish sauce
- Soy sauce
- Brown sugar
- Honey
- Lime juice
- Black pepper
- Sesame oil (optional)
- Chili (if using)
Mix thoroughly until the sugar dissolves. The marinade should smell aromatic, slightly sweet, and savory.
Step 4: Marinate the Chicken
Add the chicken to the bowl and massage the marinade into every piece. Ensure all surfaces are well coated.
Cover and refrigerate for at least 4 hours, but ideally overnight (8–24 hours). Longer marination deepens the flavor and tenderizes the meat.
Turn the chicken once or twice during marinating for even absorption.
Step 5: Prepare the Grill
For authentic flavor, a charcoal grill is ideal. However, a gas grill, grill pan, or oven broiler also works well.
Preheat grill to medium-high heat (around 190–200°C / 375–400°F). Oil the grates lightly to prevent sticking.
Step 6: Grill the Chicken
Remove chicken from the refrigerator 20–30 minutes before cooking.
Shake off excess marinade (but do not wipe it clean — the caramelization is key).
Place chicken skin-side down over medium heat.
Grill for approximately:
- 6–8 minutes per side for boneless thighs
- 8–10 minutes per side for bone-in pieces
Flip only when the chicken releases naturally from the grill.
Internal temperature should reach 75°C (165°F).
The sugars in the marinade will create a glossy, caramelized crust with beautiful char marks. If it browns too quickly, move to indirect heat to finish cooking.
Step 7: Rest Before Serving
Transfer cooked chicken to a plate and let it rest for 5–10 minutes before slicing. This step keeps the meat juicy and flavorful.
Slice into strips for serving over rice or noodles.

Pro Tips for Perfect Gà Nướng Xả
1. Finely Mince Lemongrass
Large pieces can burn or remain fibrous. The finer the chop, the better the flavor integration.
2. Balance Sweetness
Sugar promotes caramelization but can burn. If grilling over very high heat, reduce sugar slightly.
3. Don’t Skip Resting
Resting ensures juices redistribute throughout the meat.
4. Use Thighs Instead of Breasts
Thighs remain juicy and flavorful even if slightly overcooked.
Storage & Meal Prep
Refrigeration:
Store leftovers in an airtight container for up to 3 days.
Freezing:
Freeze cooked chicken for up to 2 months.
Reheating:
Reheat in oven at 180°C for 10–12 minutes or in an air fryer for crispy edges.
This chicken is excellent for meal prep bowls and lunch boxes.
Flavor Variations
You can experiment while keeping the essence intact:
- Add grated ginger for warmth
