Oven Bake: Preheat oven to 200 °C. Place fish nuggets on a baking tray in the centre of the oven and bake for 15–20 minutes. Turn halfway through cooking. The coating should be golden-brown and crisp, and the fish should be fully cooked.
Air Fry: Evenly space the fish nuggets in the frying basket. Cook at 180 °C for approximately 15 minutes. Gently shake halfway through the cooking time. The coating should be golden-brown and crisp, and the fish should be fully cooked.
