Pour enough boiling water into four 250ml (1 cup) ovenproof ramekins (or dishes) until the water reaches halfway up the sides. Using 4 eggs, crack one egg into each into each. Place in the air fryer basket and cook at 200C for 6 minutes for soft centres (see notes). Open the air fryer basket and stand ramekins in the air fryer basket for 1 minute to finish cooking and cool slightly. CAUTION: the ramekins will be very hot. Be very careful and use an oven mitt, if you have one, or a tea towel when removing the ramekins from the air fryer basket.
Use a large dessert spoon to carefully scoop out the cooked eggs and transfer to a plate lined with paper towel to drain slightly. Place eggs on toast and season, to serve.
