1. Add some seasoning to the flour in a bowl. Each fish fillet should be equally covered after being tossed in the flour.
2. In a nonstick skillet over medium-high heat, heat half the oil. Cod should be added and fried for two minutes on each side, or until golden.
3. Place a roasting pan with the cod in it. Then, sprinkle the remaining oil over the fish and add the thyme and lemon slices. Bake the dish in HYSapientia Air Fryer Oven for 10 minutes, or until thoroughly done, at 200 degrees.
