📝 About This Recipe

Transport yourself to a classic mid-century American diner with this impeccably creamy and nostalgic egg salad. This recipe elevates the humble lunch staple by using a precise hard-boiling technique for tender whites and jammy-yet-set yolks, folded into a tangy, herb-flecked dressing. It is the quintessential comfort food—a balance of rich protein, crunchy aromatics, and buttery toasted bread that feels like a warm hug in sandwich form.

🥗 Ingredients

The Eggs

  • 8 pieces Large Eggs (preferably pasture-raised and cold from the fridge)
  • 2 cups Ice Cubes (for the ice bath to stop the cooking process)

The Dressing

  • 1/2 cups Mayonnaise (high-quality, such as Duke's or Hellmann's)
  • 1 tablespoon Dijon Mustard (for a sophisticated tang)
  • 1 teaspoon Yellow Mustard (for that classic diner color and acidity)
  • 1 teaspoon Lemon Juice (freshly squeezed)
  • 1/4 teaspoon Smoked Paprika (for a subtle depth of flavor)
  • 1/2 teaspoon Kosher Salt (or to taste)
  • 1/4 teaspoon Black Pepper (freshly cracked)

The Crunch and Aromatics

  • 1/3 cup Celery (very finely diced for texture)
  • 2 tablespoons Red Onion (minced and rinsed under cold water to mellow the bite)
  • 1 tablespoon Fresh Chives (finely chopped)
  • 1 teaspoon Fresh Dill (minced)

The Sandwich Assembly

  • 8 slices White Bread (thick-cut pullman loaf or brioche)
  • 2 tablespoons Unsalted Butter (softened, for toasting the bread)
  • 4-8 leaves Bibb Lettuce (washed and dried thoroughly)

👨‍🍳 Instructions

  1. 1

    Fill a large saucepan with enough water to cover the eggs by at least an inch. Bring the water to a rolling boil over high heat.

  2. 2

    Gently lower the cold eggs into the boiling water using a slotted spoon to prevent cracking. Immediately turn the heat down to a simmer.

  3. 3

    Simmer the eggs for exactly 11 minutes. While they cook, prepare a large bowl with cold water and the ice cubes to create an ice bath.

  4. 4

    Once the timer goes off, transfer the eggs immediately to the ice bath. Let them sit for at least 10 minutes; this stops the cooking and prevents the green ring around the yolk.

  5. 5

    Gently crack the eggshells all over and peel them under the water or under a cold running tap. Pat the peeled eggs dry with a paper towel.

  6. 6

    On a clean cutting board, chop the eggs into 1/2-inch pieces. You want them chunky enough to have texture, not a paste.

  7. 7

    In a large mixing bowl, whisk together the mayonnaise, Dijon mustard, yellow mustard, lemon juice, smoked paprika, salt, and pepper until smooth.

  8. 8

    Fold in the finely diced celery, minced red onion, chives, and dill into the dressing base.

  9. 9

    Add the chopped eggs to the bowl. Using a rubber spatula, gently fold the eggs into the dressing until evenly coated, being careful not to over-mix and smash the yolks.

  10. 10

    Taste the salad and adjust seasoning with extra salt or pepper if needed. For the best flavor, let the mixture chill in the fridge for 30 minutes.

  11. 11

    Heat a skillet over medium heat. Lightly butter one side of each bread slice and toast in the pan until golden brown and slightly crisp.

  12. 12

    To assemble, place a leaf or two of Bibb lettuce on the untoasted side of four bread slices (the lettuce acts as a moisture barrier).

  13. 13

    Scoop a generous portion of the egg salad onto the lettuce, spread to the edges, and top with the remaining bread slices.

  14. 14

    Slice diagonally and serve immediately while the bread is still warm and the salad is cool.

💡 Chef's Tips

For the easiest peeling, use eggs that are a week old rather than farm-fresh, as the membrane loosens over time. Always rinse your minced red onions in a fine-mesh sieve under cold water; this removes the sulfurous 'burn' and keeps the flavor clean. If you prefer a creamier texture, mash two of the hard-boiled yolks into the mayonnaise before adding the rest of the chopped eggs. Do not skip the lettuce; it provides a necessary crunch and prevents the bread from becoming soggy if the sandwich sits for a few minutes. Avoid over-chopping the eggs; a rustic, chunky texture is the hallmark of a high-quality diner sandwich.

🍽️ Serving Suggestions

Serve alongside a pile of kettle-cooked sea salt potato chips for maximum crunch. A crisp dill pickle spear is the traditional and essential acidic accompaniment. Pair with a cold glass of sweetened iced tea or a classic lemonade. For a lighter option, serve the egg salad inside a hollowed-out heirloom tomato or on a bed of arugula. A side of creamy coleslaw balances the richness of the egg salad perfectly.
