What Makes It Irresistible
- Layered flavor: Comforting, rich, and beautifully balanced.
- Easy method: Steps designed for any skill level.
- Adaptable: Works with pantry swaps and seasonal twists.
- Prep-friendly: Can be made ahead without losing quality.
Ingredient Guide
- 6 large eggs: I prefer organic eggs for their rich flavor; they create the creamy base for the egg salad.
- 1/4 teaspoon sugar: Adds just a hint of sweetness to balance the savory notes.
- 1/4 teaspoon salt & black pepper: Essential for seasoning and enhancing the egg’s natural flavors.
- Milk or plant milk (optional): A splash helps loosen the texture if you go with hard-boiled eggs, keeping it silky.
- 4 tablespoons Japanese mayonnaise: The secret weapon for that perfect umami tang and velvety mouthfeel.
- 4 slices Japanese milk bread: Its soft crumb and slight sweetness make it the ideal sandwich canvas.
- 2 tablespoons unsalted butter, softened: Spread on the bread for extra richness and subtle crisping.
- Chives (optional): A fresh herbal garnish that adds a lovely, mild onion note.
Prep Before You Begin
Before diving in, set aside about 25 minutes — this includes boiling the eggs and assembly. The magic lies in having everything prepped and within reach, from your butter softened just enough to spread without tearing the bread, to the eggs peeled and ready for mashing. I always recommend preparing an ice bath before cooking the eggs; it’s a small step that makes peeling a breeze and stops the cooking at the perfect moment. Nothing derails the texture like overcooked eggs.
Tools & Setup
Here’s what you’ll want on hand so your Japanese Egg Sandwich (Tamago Sando) Recipe comes together smoothly—plus optional extras that make the process even easier.
How to Make Japanese Egg Sandwich (Tamago Sando) Recipe
Let’s break it down step-by-step, with tips to get the texture and balance just right.
- Prepare an ice bath. Fill a large bowl with cold water and ice — this will halt the cooking of your eggs and make peeling easier.
- Boil the eggs. Bring a pot of water to a boil, enough to cover the eggs fully. Lower 6 large eggs gently using a ladle.
- Cook to your preferred doneness. Boil for 7 minutes for medium soft boiled eggs (my personal favorite), then turn off the heat and let them sit in the water for 1 more minute. For fully hard boiled eggs, boil 10 minutes straight.
- Shock them in the ice bath. Immediately transfer the eggs to the ice bath for about 2 minutes. I find peeling easier when eggs are still slightly warm but not hot.
- Peel gently. Tap the eggshell to crack, then peel starting from the wider end where the air pocket is.
- Mash the eggs. Transfer peeled eggs to a bowl and mash gently. Aim for pieces smaller than a pea but bigger than minced. You can use a fork, but I like using a small knife to get the perfect chunkiness—you’ll feel the difference.
- Season well. Add 1/4 teaspoon sugar, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Mix and taste. Adjust seasoning to your preference.
Expert Tips to Nail It
Use Japanese mayonnaise if possible — its light tang and creamy texture are key. Don’t over-mix the egg salad; keeping some small chunks adds a delightful texture contrast. If you prefer a lighter spread, try blending in a teaspoon or two of milk; it’s subtle but noticeable.
- Incorporate the mayo. Add 4 tablespoons Japanese mayonnaise to the egg mixture and gently fold to combine. This will give the salad its signature rich, velvety texture.
- Butter the bread. Spread 1/2 tablespoon softened unsalted butter evenly on each slice — this adds a slight richness and helps the bread toast lightly if you choose to warm it.
- Assemble the sandwich. Spread a generous layer of egg salad on one slice of bread, then top with the other slice, buttered side down. Press gently to help the layers meld together.
- Trim the crusts. Carefully slice off the crusts for that iconic, soft-edged silhouette.
- Garnish and serve. Sprinkle sliced chives on top if you like a fresh herbal note. Slice the sandwich in half and enjoy immediately for the best texture.
Creative Variations for Japanese Egg Sandwich (Tamago Sando) Recipe
- Add a touch of wasabi mayo: Mix a little wasabi into the mayo for a gentle kick that pairs beautifully with the creamy egg.
- Include crunchy cucumbers: Thinly sliced cucumber adds a refreshing crispness that cuts through the richness.
- Use avocado slices: For a buttery complement and silky mouthfeel.
- Season with shiso leaves: These give a subtle herbal aroma that elevates the sandwich.
- Make it vegan: Swap eggs for mashed tofu seasoned with turmeric and black salt, and use vegan mayo.
- Turn it into a bento treat: Cut sandwiches into bite-sized pieces and arrange beautifully with pickles and fruit.
Storage, Freezing & Reheating
- Refrigerate: Wrap sandwiches tightly in plastic wrap and keep in the fridge for up to 2 days. They’re best eaten fresh but hold up well overnight.
- Freeze: Due to the delicate texture of the bread and egg salad, freezing is not recommended.
- Reheat: If you like a warm sandwich, toast the bread first before assembling to avoid sogginess.
- Make ahead: Prepare the egg salad up to 1 day in advance and store in an airtight container; assemble the sandwiches just before serving.
Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
- Can I use regular mayonnaise instead of Japanese mayo? Yes, but Japanese mayo tends to be creamier and tangier, which enhances the sandwich’s flavor.
- How do I get the perfect soft boiled eggs? Boil for exactly 7 minutes, then rest for 1 minute off heat. Shock in ice water immediately to stop cooking.
- Why do I mash eggs into medium-sized chunks? Keeping some texture prevents the sandwich from becoming too pasty—makes for a more interesting bite.
- Can I use other bread types? You can, but Japanese milk bread’s softness and slight sweetness make it ideal. White sandwich bread works as a substitute.
- Is it okay to add extra seasoning? Absolutely! A pinch of smoked paprika or a few drops of soy sauce can add lovely twists.

Ingredients
Egg Salad
- 6 large Pete and Gerry’s Organic Eggs
- 1/4 teaspoon sugar
- 1/4 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1 to 2 teaspoons milk or plant milk (Optional)
- 4 tablespoons Japanese mayonnaise
Sandwich
- 4 slices Japanese milk bread
- 2 tablespoons unsalted butter, softened
- Chives, sliced (for garnish) (Optional)
Instructions
- Prepare the ice bath: Fill a large bowl with ice and water to create an ice bath. This will stop the eggs from cooking further and make peeling easier.
- Boil the eggs: Bring a medium-sized pot of water to a boil, ensuring the water level can cover the eggs fully. Gently lower the eggs into the boiling water using a ladle. Boil for 7 minutes for medium soft boiled eggs or 10 minutes for hard boiled eggs. Then turn off the heat and let the eggs sit in the hot water for 1 minute if opting for medium soft boiled.
- Cool and peel the eggs: Immediately transfer the eggs to the ice bath and let them sit for 2 minutes to halt cooking. Remove eggs while still lukewarm and peel the shells off carefully.
- Mash the eggs: Place peeled eggs into a large bowl and mash them with a fork to break into small pieces, smaller than a pea but larger than minced. For easier mashing, use a paring knife if desired.
- Season and mix: Add sugar, salt, and black pepper to the mashed eggs. Mix well, then stir in Japanese mayonnaise and milk if using hard boiled eggs. Adjust seasoning to taste by adding more salt, pepper, or mayonnaise as needed.
- Butter the bread: Spread 1/2 tablespoon of softened unsalted butter evenly on each slice of Japanese milk bread.
- Assemble the sandwiches: Spread the prepared egg salad generously on one slice of buttered bread. Top with another slice of bread, butter side down. Gently press the sandwich together to secure the filling. Slice off the crusts from the sandwich for a clean presentation. Repeat for the second sandwich.
- Garnish and serve: Optionally, sprinkle sliced chives on top for added flavor and color. Cut the sandwiches in half and serve immediately for the best texture and taste.
- Storage: Wrap each sandwich tightly with plastic wrap and store in the refrigerator. Consume within 2 days for optimum freshness.
Notes
- Using soft or medium soft boiled eggs yields creamier, less crumbly egg salad than fully hard boiled eggs.
- Japanese mayonnaise is preferred for its rich umami flavor but regular mayonnaise can be used in a pinch.
- Removing crusts creates the signature soft and delicate Tamago Sando experience.
- Adjust sugar and salt to taste based on egg freshness and personal preference.
- Milk or plant milk is optional but helps loosen the egg salad if it feels too dense.
- Chives add a subtle onion flavor and visual appeal but can be skipped.
