Place a slice of bread on the bottom and lay a flat slice of ham evenly on top.
Pipe mayonnaise in a square shape along the edges of the bread to form a wall, making sure to fill all gaps.
Carefully crack 1 egg into the center of the mayo wall.
Place the whole assembly into the air fryer basket.
Bake in the air fryer set to 180°C (360°F) for about 20 minutes until golden brown.
After removing, drizzle zigzag lines of tangy ketchup to taste, then cut into bite-sized pieces.

Cooking tips 💡
To prevent egg spillage when cracking, it's safer to place the bread in the air fryer basket first and then crack the egg directly into it, rather than cracking it elsewhere and transferring.
If you prefer a soft, runny yolk, adjust the time significantly to between 7 to 10 minutes.
