Traditional Japanese Egg Salad Recipe: Silky Mayonnaise and Dill Magic

This traditional Japanese egg salad transforms simple ingredients into a silky, creamy masterpiece that balances rich mayonnaise with bright dill and cucumber. The secret lies in perfectly hard-boiled eggs—tender yet firm—chopped into delicate cubes that melt in your mouth.

I first discovered this recipe during a visit to a Kyoto café, where the dish was served as a delicate side to miso-glazed fish, and it quickly became my go-to for elegant yet effortless meals.

The magic happens in the dressing: a smooth blend of Japanese-style mayonnaise, rice vinegar, and a touch of sugar creates a tangy-sweet balance that elevates the dish beyond ordinary egg salad. Fresh dill and finely chopped cucumber add a crisp, herbal brightness, while scallions lend a subtle sharpness.

This recipe delivers restaurant-quality texture and flavor without requiring advanced techniques—just precise chopping and gentle folding.

What you’ll end up with is a dish that’s both comforting and refined: creamy yet light, with every bite offering a harmonious blend of textures and flavors. The eggs stay moist and tender, the dressing clings beautifully, and the presentation is effortlessly elegant.

It’s the perfect side for sushi, a light lunch on its own, or a component in a bento box.

Serve it chilled on a bed of lettuce or alongside grilled fish for a truly authentic Japanese experience. Let’s make this salad—it’s simpler than it looks, but the results are unforgettable.

Ingredients for traditional japanese egg salad

Eight simple ingredients create this delicate, restaurant-worthy Japanese egg salad masterpiece.

The eggs are everything here—fresh, organic eggs from the grocery store's refrigerated section make all the difference. Trader Joe's or Whole Foods carry excellent options, but any high-quality eggs will work. The secret to perfect texture is shocking them in ice water immediately after boiling—keeps them tender yet firm. For the dressing, Japanese-style mayonnaise is non-negotiable—Kewpie's bright yellow color and tangy richness is the hallmark of authentic flavor. If you can't find it, Hellmann's Japanese version is a solid backup. The dill should be fresh, not dried—it's what gives that bright, herbal note that sets this apart from Western egg salad.

No Japanese mayonnaise? Substitute with regular mayo plus 1 tsp rice vinegar—it won't be identical, but close enough. Fresh dill wilt fast, so buy it the day you cook and store it in a jar of water in the fridge. The cucumber needs to be Persian or Kirby type—they're less watery and hold their shape better. For extra authenticity, swap the sugar for 1 tsp mirin (find it in the Asian foods aisle). The scallions can be regular green onions, but the white part should be thinly sliced for that delicate crunch. Want to make it ahead? Assemble everything except the eggs—they can be boiled and chopped up to 2 days ahead and stored in the fridge.

Boiled eggs keep 5-7 days in the fridge once peeled, but for this salad, use them within 3 days for best texture. The dressing components (mayonnaise, vinegar, sugar) will last 2 weeks in the fridge. For serving, butter lettuce leaves work perfectly—they're delicate enough to hold the salad without overpowering. Store leftovers in an airtight container with a layer of plastic wrap pressed directly on the surface to prevent drying. This salad tastes even better the next day as the flavors meld—make extra for lunch the following day!

Step-by-step instructions for traditional Japanese egg salad

Here's how to make this velvety, herb-forward egg salad that's the heart of Japanese bento boxes.

Place the 8 whole large eggs in a saucepan and cover them with cold water by about 1 inch. Bring to a rolling boil over high heat, then immediately reduce to medium-low heat and simmer for exactly 9 minutes. This precise timing ensures the yolks remain silky and creamy—not rubbery or overcooked.

Transfer the eggs to a bowl of ice water and let them cool for 10 minutes. The cold water stops the cooking process instantly, preventing the yolks from becoming grainy. You'll know they're ready when they're completely cool to the touch and the shells peel away effortlessly.

Gently tap each egg on a hard surface, then roll to crack the shell all over. Peel under running water if needed—this removes any stubborn bits without breaking the yolks. Chop the eggs into ¼-inch pieces, keeping yolks and whites together for an even texture. I like to use a sharp chef's knife for clean cuts that won't mash the yolks.

Place the chopped eggs in a large mixing bowl. The pieces should be uniform in size—this ensures even distribution of the mayonnaise and herbs throughout. If any yolks break during chopping, don't worry; they'll blend seamlessly into the mixture.

In a separate small bowl, combine the 0.25 cup finely chopped fresh dill, 0.5 cup seeded and diced Persian cucumber, and 3 whole thinly sliced scallions. Add the 1 tablespoon seasoned rice vinegar, 1 teaspoon granulated sugar, 0.5 teaspoon salt, and 0.25 teaspoon freshly ground black pepper. Mix gently to distribute the flavors evenly—this herb-cucumber mixture is the secret to that bright, refreshing taste.

The sugar in this step might seem unusual, but it balances the acidity of the rice vinegar and enhances the freshness of the herbs. Taste the mixture now—it should be vibrant, slightly sweet, and tangy. This is your flavor foundation before adding the eggs.

Add the 0.5 cup Japanese-style mayonnaise to the herb mixture and stir until fully combined. Then, gradually fold in the chopped eggs using a silicone spatula, working from the center outward. This gentle folding technique keeps the eggs intact while creating a silky, cohesive texture. You're aiming for a creamy yet slightly chunky consistency—like a cross between a salad and a mousse.

Taste and adjust seasoning if needed. You might want to add a pinch more salt or a splash of rice vinegar to balance the flavors. The mayonnaise should be the binder that holds everything together without overpowering the fresh herbs and bright cucumber.

Divide the egg salad among 4 whole butter lettuce leaves, arranging it in the center of each leaf. The lettuce acts as a natural bowl that keeps the salad contained while adding a crisp, fresh contrast. Sprinkle each serving generously with 1 teaspoon toasted sesame seeds—this adds a nutty crunch that complements the silky texture perfectly.

Serve immediately for the best texture and flavor. The egg salad keeps well in the fridge for up to 2 days, but the sesame seeds are best added fresh before eating to maintain their crispness. This traditional preparation delivers that authentic Japanese bento box flavor you're craving—creamy, herby, and perfectly balanced.

Essential equipment for this recipe

Precision Egg Tools

Start with a high-quality chef's knife (I recommend Shun Premier or Wüsthof Ikon) for clean egg chopping—its sharpness prevents crushing yolks. A small saucepan with a lid (like All-Clad Stainless) is ideal for boiling eggs, as it distributes heat evenly.

For peeling, a pair of tongs and a small bowl of ice water are essential for stopping the cooking process instantly. 🥚

Mixing Essentials

Use a large mixing bowl (I prefer Le Creuset stoneware) to hold the chopped eggs—its weight helps keep everything contained during folding. A silicone spatula (like OXO Good Grips) is perfect for gently combining ingredients without breaking the eggs.

For measuring, a small liquid measuring cup (with a spout) makes it easy to add the 1 tablespoon rice vinegar and 0.5 cup mayonnaise precisely.

Herb and Garnish Prep

A sharp pairing knife (such as Victorinox Fibrox) is best for chopping 0.25 cup fresh dill and 0.5 cup Persian cucumber into fine pieces—this ensures even distribution. For scallions, a mandoline (like Benedict 3-in-1) gives you perfectly thin slices every time.

Toast 1 teaspoon sesame seeds in a dry small skillet over medium heat for 1-2 minutes until golden—this adds that nutty crunch that elevates the dish.

Serving Presentation

For plating, butter lettuce leaves (like Little Gem) act as natural bowls—choose ones with sturdy stems for easy handling. A small fine-mesh strainer helps drain any excess water from the cucumber before dicing.

For extra elegance, a tweezers set (like OXO Good Grips) makes it easy to place sesame seeds precisely on top. A small serving spoon (about 2 tablespoons) helps portion the salad evenly for guests.

Optional Upgrades

Invest in a digital kitchen scale (like OXO Good Grips) for precise measurements of herbs and spices—this is especially helpful when substituting mirin for sugar. A small whisk (such as Zyliss 3-in-1) comes in handy if you prefer to emulsify the mayonnaise and vinegar mixture for extra smoothness.

For a professional touch, a clear glass serving dish (like Pyrex) keeps the salad looking fresh and inviting in the fridge.
