What is Tamago Sando?
Tamago Sando (卵サンド) is a popular Japanese sandwich that has an egg as the main filling. Although egg sandwiches are found in many countries, they’ve been exceptionally popular in Japan. You can find them in bakeries, supermarkets, and convenience stores all over Japan.
The classic Japanese egg sandwich consists of boiled eggs mixed with mayonnaise. However, many variations of this sandwich exist, including Japanese rolled omelet sandwiches, half-boiled egg sandwiches, and other unique varieties.
This sandwich is a timeless classic that has remained popular for decades and decades. You’ll even see long lines of people waiting to buy them at popular shops in Tokyo.
How I Developed This Recipe
For my Tamago Sando recipe, I chose to stick with the classic combination of hard-boiled eggs and mayonnaise, but with a twist.
I added honey for a touch of gentle sweetness and Japanese mustard for a subtle kick. This blend of flavors elevates the traditional egg sandwich, making it a delightful lunch treat.
I recommend giving this recipe a try for a classic yet enhanced egg sandwich experience!
Ingredients & Substitution Ideas
- Eggs: The recipe calls for medium-sized eggs, but small or large ones can also be used based on your availability.
- Salt & Black Pepper: A subtle seasoning base for the eggs helps the flavors shine.
- Slices of Loaf Bread: Soft white sandwich bread works best for this recipe. If you’re interested in making the Japanese version, check out our shokupan recipe for guidance.
- Honey: Any regular honey you usually use is fine. It adds a nice touch of sweetness.
- Japanese Mayonnaise: Kewpie mayonnaise is the ideal choice for its unique flavor, but other types of mayonnaise will also work well.
- Karashi (Japanese Mustard): I recommend using S&B’s karashi tubes. If unavailable, smooth Dijon mustard is a good substitute.
- Unsalted Butter: It’s important to use unsalted butter to control the overall saltiness. If you only have salted butter, just reduce the amount of salt in the recipe.

Visual Walkthrough & Tips
Here are my step-by-step instructions for how to make Tamago Sando at home. For ingredient quantities and simplified instructions, scroll down for the Printable Recipe Card below.
Start by boiling enough water in a pot to submerge the eggs completely.
Once the water is boiling, gently add the eggs and boil them for 10 minutes. This timing is perfect for getting the right consistency for our egg mixture.
While you wait for the eggs, take the butter out of the refrigerator and leave it on the counter to come to room temperature.
After the eggs have boiled for 10 minutes, transfer them to a bowl of cold water. Peel off the shells and then pat them dry with kitchen paper to remove any excess water.
Place the boiled eggs in a bowl, add a pinch of salt and pepper, and start mashing them with a spatula.
Once the egg whites are finely mashed, mix in mayonnaise and honey.
Keep mixing for several minutes until the mixture becomes sticky and well combined.
Now, take two slices of bread and cut off the crusts (optional).
A little note: I cut off the crusts for the photo, but leaving the crusts on is totally fine. If you remove the crusts, you can blend them to make homemade panko breadcrumbs.
Spread butter on one side, and mustard on the other side.
Finally, spread the egg mixture over one of the bread slices.
Close the sandwich with the other slice, and your delicious Japanese-style egg sandwich is ready to enjoy!Jump to Full Recipe Measurements
Tips for Clean Cuts
Tamago sando contains a wet filling that can make it difficult to get a clean cut. Here are a few tips to help improve presentation:
- Chill the filling: If you have time, chill the filling for a little while to make it more stable.
- Wrap and chill the whole sandwich: Again, if time permits, you can chill the assembled sandwich for 20 minutes to stabilize the filling and make it easier to cut. If you use this method, make sure to wrap it with plastic wrap to stop the bread from drying out.
- Use a serrated bread knife: This will allow you to cut the sandwich in a sawing motion so that you don’t squash the bread and push the filling out.
- Wipe the knife between each cut: Wipe away any filling on the blade of the knife before you make each cut, this will ensure clean cuts every time!
How to Store
Once assembled, Tamago Sando is best chilled and eaten the same day. If serving in a lunchbox or bento, store it with an icepack to keep it cool and eat it within a few hours.
The filling can be kept in a sealed container in the refrigerator for 2-3 days for convenient sandwich-making in the morning.
