Japanese 7-Eleven Egg Salad Sandwich

Japanese 7-Eleven Egg Salad Sandwich

Jason Diamond's desire for the famous Japanese egg salad sandwich from 7-Eleven inspired him to re-create it at home. Kewpie mayonnaise is key — made with only egg yolks and rice or apple cider vinegar — along with fluffy Japanese-style milk bread and just the right ratio of whites to yolks.


  • 5 large eggs
  • ¼ cup Kewpie mayonnaise
  • ½ teaspoon kosher salt, plus more to taste
  • ½ teaspoon granulated sugar
  • ⅛ teaspoon black pepper
  • 2 teaspoons heavy cream
  • 1 tablespoon unsalted butter, softened
  • 2 (1 1/2-ounce) Japanese milk bread slices (1/2 inch thick)


  1. Bring a medium saucepan of water to a boil over medium-high. Using a slotted spoon, carefully lower eggs into boiling water; cook 11 minutes. Remove eggs using a slotted spoon, or carefully drain into a sink. Plunge eggs into a bowl filled with ice water and let stand until cool, about 15 minutes. Drain well. Carefully peel eggs.
  2. Using your hands, split eggs open; separate yolks and whites. Place yolks in a medium bowl and mash using the back of a fork until broken down and a few chunks remain; set aside. Finely chop egg whites; place in a small bowl and set aside.
  3. Add mayonnaise, salt, sugar, and pepper to mashed yolks in bowl; gently stir until mixture is combined and some chunks remain. (Mixture should not be too chunky or a paste.)
  4. Add half of the chopped egg whites to yolk mixture in medium bowl; reserve remaining egg whites for another use. Gently fold whites into yolk mixture until just coated. Chill for 1 hour.
  5. Stir cream into chilled egg mixture; season with additional salt to taste. Set aside. Spread butter evenly over one side of each bread slice. Top one slice, butter side up, with egg salad. Cover with remaining slice, butter side down. Trim off and discard crust; cut sandwich in half diagonally so you have two triangles. Serve.
