Cooking frozen fish fillets in an air fryer is a quick and convenient way to prepare a delicious meal. Simply preheat the air fryer to 200°C (about 400°F) while you take the fillets straight out of the freezer. There’s no need to thaw them; just place them in a single layer in the basket. Lightly spray with olive oil and season with salt, pepper, or your favourite herbs for added flavour. Cook for approximately 12-15 minutes, turning halfway through, until the fish is golden and cooked through with a delightful, crispy exterior. Serve with a wedge of lemon and a side of tartar sauce for a classic touch. Enjoy your perfectly cooked fish fillets with minimal hassle and maximum flavour!
