Let’s make your own konbini-style Japanese egg sandwich at home!
???? Ingredients (Makes 2 Sandwiches)
For the Egg Filling:
- Eggs – 4 large (200g)
- Kewpie mayonnaise – 40g (about 2½ tbsp)
- Salt – ¼ tsp (1.5g)
- Sugar – ¼ tsp (1.5g)
- Freshly cracked black pepper – to taste
For Assembly:
- Japanese milk bread (Shokupan or soft white sandwich bread) – 4 slices (about 160g)
- Softened butter (optional) – 10g (for spreading)
???????? Instructions
Step 1: Boil the Eggs
- Bring a small pot of water to a boil. Gently add eggs and cook for 10–11 minutes for firm yolks.
- Immediately transfer eggs to an ice bath to stop the cooking. Let cool for 5 minutes, then peel.
Step 2: Make the Egg Filling
- Finely chop or mash the peeled eggs in a bowl using a fork.
- Add Kewpie mayo, salt, sugar, and a touch of black pepper. Mix until smooth and creamy but with some texture.
- Tip: Use a fine sieve to push the yolks through for extra creaminess if you want that ultra-smooth café style.
Step 3: Assemble the Sandwich
- Trim the crusts off the bread for authenticity and softness (optional but traditional).
- Butter one side of each bread slice lightly (optional, but adds richness and keeps bread from getting soggy).
- Divide the egg filling evenly and spread onto two slices of bread.
- Top with the remaining slices and press gently.
- Wrap the sandwiches in plastic wrap and chill in the fridge for 15–20 minutes to firm up (optional for cleaner cutting).
- Cut into halves or thirds — squares or triangles — and serve chilled.

???? Tips & Tricks
- Use Kewpie Mayo: The rich umami flavor makes a noticeable difference. Regular mayo can work, but Kewpie elevates it.
- Want it creamier? Add a soft-boiled egg to the mix for contrast between runny and firm.
- Make it cute! Use a sandwich cutter or mold to shape into hearts, bears, or even anime characters for bento boxes.
- No Japanese milk bread? Use the softest, fluffiest white bread you can find — or make your own shokupan for authenticity.
???? My Twist: Tamago Sando with a Yolk Bomb
Elevate your egg sandwich into a gourmet bento-style experience:
- Halve a soft-boiled egg with a jammy center (7-minute boil), and nestle it whole inside the egg salad filling before closing the sandwich.
- When you cut the sandwich in half, the beautiful golden yolk is revealed like a surprise gem in the center.
It’s viral on Instagram for a reason!
