Egg Salad Sandwiches with Peppery Watercress

egg salad sandwich with watercress on a plate

This is a classic egg salad sandwich at its best with minimal mayo and a perfect peppery bite right at the end, thanks to the watercress. 


  • 5 eggs
  • 2 tablespoons mayonnaise
  • 1 tablespoon yogurt
  • 1/2 tablespoon dijon mustard
  • 1/2 tablespoon fresh lemon juice
  • 1/4 teaspoon kosher salt, plus more to taste
  • 3 scallions, trimmed, including 1/2-inch from the top, and thinly sliced
  • 1 handful (12g) watercress 
  • 4 slices sandwich bread*


  1. Hard-boil the eggs. Place the eggs in a medium saucepan and add water to cover the bottom 1/2 of the eggs (the top half of the egg should be uncovered). Cover the pan with a lid and set the pan over high heat. Once you hear the eggs start to boil, set a timer for 9 minutes. Meanwhile, prepare a large bowl filled with ice water. When the timer rings, drain the hot water and transfer the eggs to the cold water. Once the eggs are cool enough to handle, peel them. 
  2. Make the egg salad. Cut each egg in half lengthwise, and remove the yolks from the whites. Reserve the whites for later use. Place the yolks in a food processor and add the mayonnaise, yogurt, mustard, lemon juice, and salt. Puree until smooth. Alternatively, in a large bowl, mash the yolks, mayonnaise, yogurt, mustard, lemon juice, and salt with a fork until smooth. 
  3. Chop the egg whites. Add the green onions and egg whites to the egg yolk mixture. Stir to combine. Adjust salt to taste. 
  4. To Make the Sandwiches. Lay the slices of bread flat on a cutting board or plate. Spread one-half of the egg salad onto a piece of sandwich bread. Spoon the remaining half onto another. Top the egg salad with watercress. Top each half of the sandwich with another slice of bread. Slice the sandwiches diagonally or crosswise.
