Thai lemongrass chicken is a savory, citrus-scented dish made by marinating chicken with fresh lemongrass, garlic, fish sauce, lime, and a little sugar, then searing it until browned and juicy. Thai cooks prepare lemongrass chicken in many regional and family styles; this approachable skillet version borrows familiar Thai flavor pairings and is easy to serve with rice and fresh herbs.
Ingredients
- 1½ lb boneless, skinless chicken thighs (680 g), about 4–6 thighs
- 3 lemongrass stalks (about 45 g trimmed), tough outer leaves removed
- 4 garlic cloves (12 g), peeled
- 2 tablespoons finely chopped shallot (20 g)
- ¼ cup loosely packed cilantro leaves and tender stems (10 g), plus extra to serve
- 2 tablespoons fish sauce (30 ml)
- 1 tablespoon low-sodium soy sauce (15 ml)
- 1 tablespoon fresh lime juice (15 ml), plus lime wedges to serve
- 2 teaspoons packed light brown sugar (8 g)
- 1 teaspoon neutral oil (5 ml), for the pan
- ¼ teaspoon ground white or black pepper (about 0.5 g)
- 1 small red Thai chile (5 g), thinly sliced, optional
Instructions
- Prepare the chicken and lemongrass. Pat the chicken dry and trim away any large pieces of excess fat. Cut the lemongrass stalks where the pale, firm lower section meets the greener, fibrous top. Use the bottom 4–5 inches (10–13 cm) of each stalk; discard the dry top and any tough outer layers. Thinly slice the tender centers across the stalk, then mince them as finely as you can. Fine pieces soften better and distribute the fragrant flavor through the marinade.
- Make the marinade. Finely mince the garlic, shallot, and cilantro stems. In a bowl, stir them together with the lemongrass, fish sauce, soy sauce, lime juice, brown sugar, and pepper. The mixture will be salty, tangy, and aromatic rather than sauce-like. If you have a mortar and pestle, pound the lemongrass, garlic, shallot, and cilantro stems into a coarse paste first, then mix in the liquids and sugar. This helps release their aromas, but mincing works well too.
- Marinate. Add the chicken and turn each piece so the marinade coats both sides. Cover and refrigerate for 30 minutes. If the thighs are very uneven, open them out so they are a similar thickness and cook at roughly the same pace. Avoid leaving chicken at room temperature while it marinates. Longer marinating is not necessary for this version; the lime and fish sauce flavor the surface quickly, and a lengthy soak can make the exterior overly salty.
- Heat the pan. Take the chicken out of the refrigerator while you set a large, heavy skillet over medium heat. Give the pan about 4 minutes to warm, then add the oil and swirl to coat. Lift each thigh from the marinade and let excess drip back into the bowl. Too much wet marinade in the pan can make the chicken steam instead of brown. Discard marinade that has touched raw chicken; do not use it as a finishing sauce unless you bring it to a full boil.
- Sear the chicken. Arrange the thighs in one layer, leaving a little space between them. If your skillet is small, cook in two batches rather than crowding it. Sear for about 5–6 minutes on the first side, then turn and cook for another 5–6 minutes, adjusting the heat if the lemongrass bits darken too quickly. Chicken thickness and pan temperature affect the timing, so treat the minutes as a guide, not a safety check.
- Check for doneness and rest. Insert a food thermometer into the thickest part of each thigh without touching the pan. Cook poultry to the USDA FSIS safe minimum internal temperature of 165°F (74°C). If a piece needs more time, turn it and continue cooking, checking again after a minute or two. Transfer cooked chicken to a clean plate and rest for 3 minutes. Scatter cilantro leaves and the optional sliced chile over the top, then serve with lime wedges.
Tips
Choose the tender part of the lemongrass. Fresh lemongrass is sold as firm stalks, often near fresh herbs or in an Asian grocery store. The lower section is the part to use; the green tops and woody outer layers are too fibrous for this quick marinade. Mince it very finely so diners do not get long, tough strands. If fresh stalks are unavailable, use 1 tablespoon (15 g) lemongrass paste in place of the three stalks. Paste is softer and less bright, so start with that amount and taste the marinade before adding the chicken.
Balance the salty and sour flavors. Fish sauce brands vary in intensity, and soy sauce adds more salt. Use the quantities as a starting point, then taste a small dab of marinade before it touches raw chicken. If it tastes sharply salty, add another teaspoon of lime juice or a teaspoon of water. The cooked chicken should be savory and fragrant, not taste like straight fish sauce. Brown sugar rounds out the salt and lime; it is not meant to make the dish sweet.
Keep the pan hot, but not smoking. A moderate, steady heat gives the chicken time to cook through while browning the marinade. If the minced aromatics begin to turn very dark before the chicken is done, lower the heat slightly. Wipe out burnt bits between batches if needed, then add a little fresh oil. A crowded pan traps moisture and prevents a good sear, so batch-cooking is better than squeezing every thigh into a small skillet.
Use a thermometer rather than color alone. Thigh meat can remain a little pink near a joint even when cooked, while browned surfaces do not guarantee a safe center. Check each thick piece at its thickest point. If using a grill instead, cook over medium heat and turn as needed to avoid flare-ups from dripping marinade; still confirm 165°F (74°C) with a thermometer.
Serving Suggestions
Serve the chicken hot with jasmine rice, which catches the savory juices and makes a simple, satisfying plate. Sticky rice is another good choice and gives the meal a more hands-on feel. Add lime wedges at the table so each person can adjust the brightness, and finish with cilantro leaves or thinly sliced scallions. For a fuller dinner, put out a bowl of sliced cucumber, shredded cabbage, or lightly dressed greens. Their cool crunch balances the warm, salty-sour chicken without competing with the lemongrass.
A quick dipping sauce is optional rather than essential. Stir together 1 tablespoon (15 ml) lime juice, 1 tablespoon (15 ml) water, 1 teaspoon (5 ml) fish sauce, and a pinch of sugar; add minced chile if you like heat. Taste before serving because the chicken is already seasoned. For a more substantial spread, include a mild vegetable stir-fry or steamed green beans. Keep those sides lightly seasoned so the fish sauce, lime, and aromatic chicken remain the focus.
Variations
Make it spicy. Add one thinly sliced Thai chile to the marinade or serve sliced chiles separately for guests to add at the table. Thai chiles are small but potent, so begin with half if you are unsure of their heat. A pinch of red pepper flakes is a practical substitute, though it gives a less fresh, less distinctly herbal heat. Removing the chile seeds may soften the effect, but it will not make the pepper completely mild.
Use chicken breast. Boneless, skinless breasts work, but they are leaner and can dry out if cooked as long as thick thighs. Cut large breasts horizontally into thinner cutlets so they cook evenly, and check the thickest part with a thermometer for 165°F (74°C). The flavor will be similar, while the texture will be firmer and less rich. You can also use bone-in pieces, but they take longer and are harder to cook evenly in a skillet; rely on the thermometer, not the timing given here.
Try a grill or grill pan. Grill the marinated thighs over medium heat, turning as needed until browned and cooked through. A grill pan gives some charred marks indoors, though it may smoke more than a flat skillet. Brush off excess marinade before grilling to limit scorching, and discard any marinade left in the raw-chicken bowl. Whichever method you use, check the center of every piece for the poultry safe minimum temperature.
Make a meat-free version. Use thick slices of firm tofu and reduce the marinating time to about 15 minutes so they take on flavor without becoming too salty. Pat the tofu dry first, then sear it until golden on both sides; the texture will be softer and less juicy than chicken. For a vegetarian marinade, replace the fish sauce with an equal amount of soy sauce or a vegetarian fish sauce. That swap makes the seasoning less complex, so add a little extra lime and taste before cooking.
Storage and Reheating
Refrigerate cooked chicken within 2 hours of cooking, in a covered shallow container. It keeps for 3–4 days in the refrigerator. Store rice separately so it cools and reheats evenly. For longer storage, freeze the cooked chicken in a sealed freezer-safe container for up to 2–3 months for best quality; thaw it in the refrigerator before reheating. Do not store cooked chicken at room temperature, and discard it if it has been left out longer than the safe window.
Reheat portions in a covered skillet over low heat with a spoonful of water, turning once, until hot throughout. You can also microwave the chicken in a covered microwave-safe dish, checking and turning it partway through. Reheat leftovers to 165°F (74°C), checked with a food thermometer. Add a fresh squeeze of lime and fresh cilantro after reheating; those bright toppings taste fresher when added at the end. Avoid repeated cycles of cooling and reheating, which can dry the chicken and make safe handling more difficult.
Frequently Asked Questions
Can I make the marinade ahead? Yes. Mix the marinade up to 1 day ahead and keep it covered in the refrigerator, separate from raw chicken. When ready to cook, coat the chicken and marinate it for the recipe’s 30 minutes. If chicken has already been added, keep the container refrigerated and cook it within 1–2 days; do not leave it on the counter to speed up marinating.
Can I marinate the chicken overnight? It is better not to for this recipe. Fish sauce and soy sauce are both salty, while lime juice can change the texture of the surface over time. Thirty minutes gives the chicken a clear lemongrass flavor without making the outside overly seasoned. If you need to get ahead, prepare the aromatics and liquid marinade separately, refrigerate them, and combine them with the chicken shortly before cooking.
What can I use instead of fish sauce? Soy sauce is the simplest substitute, used in the same amount, but the result will taste less savory and will not have fish sauce’s distinctive fermented depth. For a vegetarian option, use vegetarian fish sauce if available. Taste the finished marinade before adding chicken, since substitute products vary in saltiness, and adjust with a little lime juice or water rather than adding more salt automatically.
Can I cook this in the oven? Yes. Arrange the marinated thighs on a lightly oiled sheet pan with space between them and roast at 425°F (220°C), turning once if you want more even browning. The time depends on thickness and your oven, so begin checking around 18 minutes and continue as needed until each piece reaches 165°F (74°C). The oven produces less direct searing than a skillet, but it is convenient when cooking a larger batch.
Is this dish very spicy? Not as written: the chile is optional, and the marinade itself is aromatic, salty, and tangy rather than hot. For a family meal, leave chile out of the marinade and offer sliced chile or chili flakes separately. Lemongrass has a citrusy, herbal fragrance, not the heat of a pepper, so the dish still tastes distinctive without any chile at all.
Can I use dried lemongrass? You can, but it is not a one-for-one replacement for fresh stalks in this marinade. Dried lemongrass is often sold as pieces that need simmering to release flavor, so it may remain woody in a quick-seared dish. If fresh lemongrass is unavailable, a prepared lemongrass paste is generally more practical. The paste gives a softer, less crisp citrus aroma than fresh minced stalks, but it keeps the recipe’s main flavor in place.
