Thai cuisine is celebrated for its bold, refreshing flavors that balance sweet, sour, salty, and spicy elements in perfect harmony. Among the many delightful dishes, Thai Grilled Fish with Lemongrass is a standout. The natural sweetness of the fish blends beautifully with the citrusy aroma of lemongrass, enhanced by garlic, chili, lime, and fish sauce. Grilled over charcoal or on a gas grill, the fish develops a smoky char while staying juicy inside.

This dish is often seen in Thai street food stalls, where whole fish is stuffed with lemongrass and herbs, then grilled until fragrant and crispy. Served with a zesty dipping sauce and sticky rice, it’s a meal that brings the taste of Thailand to your table.

Ingredients

• 2 whole sea bass, snapper, or tilapia (about 500–600 g each), cleaned and scaled
• 2 stalks lemongrass, cut into 4-inch pieces and lightly crushed
• 4 kaffir lime leaves (optional, for extra aroma)
• 2 tablespoons vegetable oil or sesame oil
• Banana leaves or foil (for wrapping, optional)

For the Marinade:

• 2 tablespoons fish sauce
• 1 tablespoon soy sauce
• 1 tablespoon lime juice
• 2 teaspoons sugar (palm sugar preferred)
• 1 tablespoon garlic, minced
• 2 red Thai chilies, chopped (adjust to spice preference)
• 1 tablespoon ginger or galangal, grated

For the Dipping Sauce (Nam Jim):

• 3 tablespoons fish sauce
• 2 tablespoons lime juice
• 1 tablespoon sugar (palm sugar or brown sugar)
• 2 Thai chilies, finely chopped

How to Make Thai Grilled Fish with Lemongrass

Step 1: Prepare the Fish

Clean the fish thoroughly and pat dry with paper towels.

Make 2–3 diagonal slits on each side of the fish to help the marinade penetrate and cook evenly.

Step 2: Make the Marinade

In a small bowl, mix fish sauce, soy sauce, lime juice, sugar, garlic, chilies, and grated ginger.

Stir until the sugar dissolves completely.

Step 3: Marinate the Fish

Rub the marinade all over the fish, making sure to get inside the slits and cavity.

Stuff the cavity of each fish with crushed lemongrass pieces and kaffir lime leaves.

Let the fish marinate for at least 30 minutes. For stronger flavor, marinate up to 2 hours in the refrigerator.

Step 4: Prepare the Grill

Heat a charcoal or gas grill to medium-high heat.

If using banana leaves, wrap the fish lightly to protect it from burning while infusing flavor. Alternatively, place the fish directly on the grill grates after brushing with oil.

Step 5: Grill the Fish

Place the fish on the grill and cook for 6–7 minutes on each side, depending on thickness.

Baste occasionally with leftover marinade or oil to keep the fish moist.

The fish is ready when the skin is crispy, slightly charred, and the flesh flakes easily with a fork.

Step 6: Prepare the Dipping Sauce

In a bowl, whisk together fish sauce, lime juice, sugar, chilies, garlic, and coriander.

Adjust flavors to taste—it should be tangy, spicy, salty, and slightly sweet.

Step 7: Serve

Transfer the grilled fish to a serving platter.

Garnish with fresh herbs and lime wedges.

Serve with dipping sauce and steamed rice for a complete Thai meal.

Chef’s Notes

Fish Choice: Sea bass, snapper, or tilapia work best, but any firm, mild-flavored fish can be used. Whole fish is traditional, but fillets work too.

Banana Leaf Trick: Wrapping in banana leaves protects the fish and adds a subtle aroma. If unavailable, foil works as a substitute.

Smoky Flavor: Charcoal grilling adds authenticity, but a gas grill or oven broiler works if charcoal isn’t an option.

Balance of Flavors: Thai cooking is about balance. Adjust sugar, lime juice, or chilies to suit your taste.

Make It a Feast: Pair this dish with papaya salad (som tam), sticky rice, and a cold Thai iced tea for a full Thai dining experience.

FAQs

1. Can I use fish fillets instead of whole fish?

Yes. Fillets work well and cook faster. Just reduce the grilling time to about 3–4 minutes per side.

2. What if I don’t have lemongrass?

You can substitute with lemon zest and a little ginger for a similar citrusy aroma, though the authentic flavor of lemongrass is hard to replace.

3. Can I bake instead of grilling?

Absolutely. Preheat the oven to 200°C (400°F) and bake the marinated fish for 20–25 minutes, finishing with a few minutes under the broiler for a charred effect.

4. How spicy is this dish?

It depends on the chilies used. Thai chilies are hot, so reduce or substitute with milder peppers if you prefer less heat.

5. What sides go best with Thai Grilled Fish?

Sticky rice, jasmine rice, papaya salad, grilled vegetables, or even a light cucumber salad make perfect accompaniments.
