Teriyaki Chicken Sandwich | Easy Japanese Remake with Egg Filling

About This Recipe

A satisfying remake sandwich built around teriyaki chicken's sweet-savory depth. Paired with a smooth egg filling, crisp lettuce, and fresh tomato, each element brings its own texture and flavor — balanced by the gentle richness of butter and a touch of whole-grain mustard.

Because the teriyaki chicken is already seasoned, no complex preparation is needed. Simply layer the ingredients and press gently — the result is a beautifully cross-sectioned sandwich that works equally well for a weekend lunch or a casual gathering.

Ingredients (Makes 2 sandwiches)

Instructions

1	Separate the yolks and whites of the hard-boiled eggs. Finely chop the whites with a knife. Tip Keeping the yolks and whites separate at this stage — rather than mashing them together — helps achieve a better balance of smoothness and texture in the finished filling.
2		In a bowl, combine the mayonnaise, milk (or soy milk), salt, and sugar. Mix well until smooth. Tip Adding a small amount of milk softens the acidity of the mayonnaise, resulting in a rounder, creamier flavor.
3		Add the egg yolks to the mayonnaise sauce from Step 2 and mix vigorously until smooth and well emulsified. Tips The liquid in the sauce reacts with the lecithin in the yolks to create emulsification, giving the filling a light, creamy texture. The mixture is ready when it falls slowly from a spoon in a thick, steady drop. For more detail on the egg filling technique, see Japanese Egg Sandwich.
4		Fold in the chopped egg whites and mix gently. The egg filling is now complete.
5		Slice the teriyaki chicken to fit the size of the bread. Slightly warm is recommended.
6		Spread butter thinly over the inner side of each slice of bread, then spread whole-grain mustard on top.
7		Layer the ingredients in the following order: bread → egg filling → teriyaki chicken → mayonnaise → tomato → lettuce → bread. Tips Pat the lettuce dry thoroughly to prevent the sandwich from becoming watery. Spreading butter first creates a moisture barrier, helping the bread stay firm.
8		Wrap tightly in plastic wrap or parchment paper. Press down gently and rest for 2–3 minutes. Tip Resting allows the layers to settle, making the sandwich easier to cut cleanly.
9		Cut in half with a sharp knife to reveal the layers.
