Ingredients

Scale

Egg Filling

  • 6 soft boiled eggs, at room temperature
  • 1 tbsp whole egg mayonnaise (S&W brand recommended)
  • 2 tsp Dijon mustard
  • 2 tsp finely chopped chives (or substitute with green onion)
  • 1/2 tsp black pepper
  • 1/8 tsp cooking or kosher salt

Sandwich

  • 8 slices soft white sandwich bread
  • Soft salted butter, for spreading on bread

Instructions

  1. Mash egg: Place the soft boiled eggs in a bowl and crush them with a fork. Once the eggs are mostly broken up, use a potato masher to mash them thoroughly until the egg white bits are very small, creating a creamy texture for the filling.
  2. Prepare filling: Add the whole egg mayonnaise, Dijon mustard, finely chopped chives, black pepper, and cooking salt to the mashed eggs. Gently stir to combine all ingredients evenly. Taste the mixture and add more salt carefully if needed, noting that eggs can surprisingly handle very little salt.
  3. Assemble sandwich: Spread soft salted butter evenly on each slice of white sandwich bread. Divide the egg filling mixture evenly onto four slices of bread, spreading it edge to edge for full coverage. Optionally, trim the crusts for a neat appearance and cut the sandwiches into your preferred shape.
  4. Serve: Serve the sandwiches at room temperature to enjoy the best possible flavor and texture.

Notes

  • Use eggs at room temperature before soft boiling to ensure even cooking.
  • The recommended mayonnaise brand is S&W for the best flavor and texture.
  • Soft white sandwich bread should be fresh and pliable for the classic soft texture.
  • Trimming the crusts is optional but provides a more traditional presentation.
  • Serving at room temperature enhances flavor; avoid chilling sandwiches before serving.
