Ingredients You’ll Need

For the Egg Salad

• 6 large eggs
• 1/4 tsp sugar
• 1/4 tsp salt
• 1/4 tsp black pepper
• 1–2 tsp milk or plant milk (optional)
• 4 tbsp Japanese mayonnaise

• 2 tbsp softened unsalted butter
• Chives, sliced (optional)

How to Make This Dreamy Tamago Sando

This Tamago Sando recipe is wonderfully simple—no complicated steps, no fancy tools, and no stress. Just creamy eggs and comforting bread doing what they do best.

1. Boil the Eggs

1. Bring a medium pot of water to a boil.
2. Carefully lower the eggs in using a ladle.
3. For medium soft-boiled eggs: cook 7 minutes, rest 1 minute.
4. For hard-boiled eggs: cook 10 minutes.
5. Transfer immediately to an ice bath for 2 minutes (don’t leave them too long—they should still feel slightly warm).
6. Peel and set aside.

2. Make the Egg Salad

1. Place the peeled eggs in a bowl and mash them—small chunks are perfect.
2. Add the sugar, salt, and pepper.
3. Mash or chop until the pieces are smaller than peas but not mushy.
4. Add the Japanese mayo (and milk if your mixture feels dense).
5. Give it a taste and adjust seasoning if needed.

3. Assemble the Sandwich

1. Spread ½ tablespoon butter on each bread slice.
2. Spoon the egg salad onto one slice and spread evenly.
3. Top with the second slice, buttered side down.
4. Trim the crusts (optional, but traditional—and honestly adorable).
5. Slice in half and garnish with chives if you like.

That’s it—pure, simple comfort.

Tips for the Best Japanese Egg Sandwich

A good Tamago Sando is all about texture: soft, creamy, cloud-like. These tips help you nail that every time.

• Go slow with the mashing. Leave tiny bits for texture—you don’t want baby food.
• Japanese mayo is key. If you can get Kewpie, use it. It’s richer and tangier.
• Milk bread = magic. It’s unbelievably soft, but if you can’t find it, use the softest white bread available.
• If your egg salad looks thick: Don’t panic. Add a splash of milk and watch it transform into silky goodness.
• For meal prep: Make the egg salad ahead, assemble fresh for the best texture.

Personal confession? This recipe has saved me more times than I can count—especially on those weeks when my brain feels like a scrambled egg itself. Having a batch of egg salad in the fridge makes life feel just a little more manageable.

FAQs About Japanese Egg Sandwiches

Can I substitute regular mayo for Japanese mayo?

Yes—but the flavor will be slightly different. Japanese mayo is smoother and richer. If using regular mayo, add a pinch of sugar and a drop of rice vinegar to mimic it.

Is Tamago Sando meant to be eaten cold or warm?

It’s typically enjoyed chilled or at room temperature. This makes it great for picnics, lunchboxes, and travel days.

What’s the best way to store leftovers?

Wrap each sandwich tightly in plastic wrap and store in the fridge for up to 2 days.

Can I add extras to the egg salad?

Absolutely! Fine-chopped celery, shredded lettuce, or a touch of Dijon can work—but keep portions small so the texture stays fluffy.
