Classic egg salad gets a savory Japanese-American twist with furikake, creamy mayonnaise, Dijon mustard, fresh dill, crisp red onion, and dill pickle. Furikake adds toasted sesame, nori, and deep umami flavor, while pickle brine provides just enough acidity to balance the richness.

Served on pillowy Japanese milk bread, the sandwich is creamy without being heavy, savory without being overly salty, and textured enough to keep every bite interesting. Chilling the filling before assembly allows the flavors to meld and gives the egg salad the ideal consistency for a neat, generously filled sandwich.

Ingredients

• 8 large hard-boiled eggs, peeled and completely cooled
• 1/3 cup Kewpie mayonnaise or high-quality mayonnaise, plus more as needed
• 2 tablespoons finely minced red onion
• 2 tablespoons finely chopped fresh dill
• 2 tablespoons finely diced dill pickle
• 1 tablespoon dill pickle brine
• 1 1/2 teaspoons Dijon mustard
• 2 tablespoons nori komi furikake, plus more for finishing
• Freshly ground black pepper, to taste
• Fine sea salt, if needed
• 8 slices Japanese milk bread, preferably shokupan

Instructions

1. Coarsely chop the hard-boiled eggs into approximately 1/2-inch pieces. Leave a mixture of smaller and larger pieces so the finished egg salad has texture rather than becoming completely smooth.
2. In a medium bowl, stir together the mayonnaise, red onion, dill, diced pickle, pickle brine, and Dijon mustard until thoroughly combined.
3. Add the chopped eggs and 2 tablespoons furikake. Gently fold with a flexible spatula until the eggs are evenly coated, taking care not to mash them.
4. Season with freshly ground black pepper. Taste before adding salt; the furikake, pickle, pickle brine, and mayonnaise may already provide enough salinity. Add a small amount of sea salt only if necessary.
5. If the mixture seems too dry, fold in additional mayonnaise 1 tablespoon at a time. The filling should be creamy and cohesive but still retain clearly defined pieces of egg.
6. Cover and refrigerate for at least 15 minutes. Chilling allows the onion, dill, pickle, and furikake flavors to meld and firms the filling for easier sandwich assembly.
7. Taste the chilled egg salad and adjust the seasoning. Add a small splash of pickle brine for additional brightness, black pepper for bite, or a little furikake for greater savory depth.
8. Arrange 4 slices of Japanese milk bread on a work surface. Divide the egg salad evenly among the slices, spreading it generously but stopping just short of the edges.
9. Sprinkle the filling lightly with additional furikake.
10. Top with the remaining bread slices and press very gently—just enough to settle the filling without compressing the soft bread.
11. If desired, trim the crusts for a Japanese-style presentation. Using a sharp serrated knife, cut each sandwich in half and serve immediately.

Cook’s Notes

Choose the right furikake: Nori komi furikake is particularly well suited to this sandwich because its seaweed and toasted sesame flavors complement the eggs without overwhelming them. Furikake blends vary considerably in saltiness, so always taste the finished filling before adding salt.

Kewpie mayonnaise: Kewpie is especially good here because of its rich, egg-forward flavor and smooth texture. Regular high-quality mayonnaise works well if Kewpie is unavailable.

Keep the eggs chunky: Avoid aggressively stirring or mashing the filling. Distinct pieces of egg white and yolk provide a much better texture.

Japanese milk bread: Soft shokupan is the preferred bread because its tender, slightly sweet crumb contrasts beautifully with the savory filling. Don’t toast it; the softness is an important part of the sandwich.

Control the onion: Finely mince the red onion so it contributes freshness and bite without dominating the egg salad. For a milder onion flavor, rinse the minced onion briefly under cold water and dry thoroughly before adding it.

Season last: Furikake, pickles, pickle brine, and mayonnaise all contribute salt. Waiting until everything is combined prevents accidental over-seasoning.

Serving Suggestions

Serve with kettle-style potato chips and a crisp dill pickle spear for a simple lunch.

For a lighter plate, pair the sandwich with a cucumber salad dressed with rice vinegar and sesame seeds, lightly dressed mixed greens, or chilled sliced cucumbers.

For entertaining, trim the crusts and cut each sandwich into quarters or small rectangles for an easy tea-sandwich-style presentation.

Beverage Suggestions

Nonalcoholic: Unsweetened iced green tea is an especially good pairing because its clean, slightly tannic character balances the creamy filling while complementing the nori and sesame. Sparkling water with lemon or cucumber is another refreshing option.

Alcoholic: A crisp Japanese lager complements the sesame and nori without overwhelming the delicate egg filling. Dry sparkling wine also works well, with its acidity and carbonation cutting through the richness of the mayonnaise.

Storage and Reheating

Store leftover egg salad in an airtight container in the refrigerator for up to 3 days.

For the best texture, store the filling separately and assemble the sandwiches shortly before serving. Fully assembled sandwiches can soften as they sit.

Do not freeze the egg salad. Freezing adversely affects the texture of both cooked eggs and mayonnaise.

This sandwich should be served chilled or cool and does not require reheating.

Variations

Spicy Furikake Egg Salad

Add 1 to 2 teaspoons sriracha to the mayonnaise mixture, or substitute a spicy furikake blend for the nori komi furikake.

Extra Japanese-Style

Replace the dill pickle and pickle brine with 1 to 2 teaspoons seasoned rice vinegar. Omit the fresh dill if desired, allowing the egg, Kewpie mayonnaise, sesame, and nori flavors to become more prominent.

Sourdough Furikake Egg Salad Sandwich

Replace the Japanese milk bread with sourdough. Lightly toast the bread for a sturdier sandwich with additional tang and textural contrast.

Vegetarian Version

Check the furikake ingredients and select a variety made without bonito flakes, dried fish, or other seafood ingredients.
