Rinse the white fish fillets under cold water and gently pat them dry with paper towels. Place the fillets in a heatproof dish that fits comfortably in your steamer, ensuring they don’t overlap.

In a small mixing bowl, combine minced garlic, finely sliced Thai chilies, fresh lime juice, fish sauce, soy sauce, sugar, and broth. Whisk until well blended.

Carefully pour the prepared lime-garlic sauce over the fish fillets, ensuring they are evenly coated.

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

Remove the dish from the steamer and drizzle any remaining sauce over the top. Garnish with cilantro and green onions. Serve immediately with steamed rice and lime wedges.
