Start by cutting your sea bass fillet into bite-sized pieces. Make sure the fillets are dry by patting them with paper towels; this helps them fry crispy. Season lightly with salt and pepper for extra flavor.
Heat cooking oil in your pan over medium heat. Add minced ginger and garlic, sautéing until they release their fragrant aroma, about 1–2 minutes. This step builds the base flavor for the dish.
Add the sea bass pieces to the pan, pouring in soy sauce, oyster sauce, sugar, and extra seasoning if needed. Cook each side until golden brown and fully cooked through, usually 5–6 minutes. Stir gently to avoid breaking the fillets.
Sprinkle chopped green onions over the cooked fish. Give a quick stir to incorporate them. Serve immediately to enjoy the fresh aroma and flavors
