Rinse the white fish fillets under cool running water to remove any impurities. Pat dry with paper towels.

Place the dried fish fillets into a heatproof plate or shallow dish that fits in your steamer.

In a mixing bowl, combine minced garlic, Thai chilies, lime juice, fish sauce, soy sauce, sugar, and broth. Whisk until sugar is dissolved.

Pour the lime-garlic sauce over the fish fillets, ensuring they are evenly coated. Let rest briefly.

Set up your steamer, fill the bottom with water, and bring it to a gentle simmer. Place the dish with fish into the steamer, cover, and steam for 10-12 minutes.

Remove the dish from the steamer, drizzle any remaining sauce over the fish, and garnish with fresh cilantro and green onions.
