Preparation Steps: Japanese-Style Egg Salad Sandwich: Place the eggs into a saucepan and cover with at least one inch of cold water. Bring to a boil over high heat, then cover and remove from the heat. Let the eggs sit for 11 minutes for soft boiled eggs, 13 minutes for medium boiled eggs, and 15 minutes for hard boiled eggs.
Arrange in Air Fryer: Place the crisper plate into the air fryer basket in Zone1. Zone 1: Place the Egg onto the crisper plate.
Cooking Settings: Zone 1: Bake at 140℃ for 13 minutes.
Finish & Serve: Zone 1: Remove the eggs when done and place them into a bowl of iced water for 5 to 10 minutes to cool down and to keep the eggs from continuing to cook. Peel the eggs, then place the yolks in a bowl and stir in the mayonnaise, mustard, sugar, and white pepper until combined. Finely chop the egg whites, then then stir into the yolks. Fold the sliced green onions and crème fraîche into the eggs, then season to taste with salt. Spread the egg mixture onto four slices of bread, top with the remaining four slices, then serve.
