Ingredients for Japanese Egg Sandwich
Essential ingredients for the egg salad
Creating a delightful Japanese Egg Sandwich starts with the perfect egg salad. Here’s what you’ll need:
- 3 large eggs (around 50 g each without shell) – Hard-boiled to perfection, these are the stars of the sandwich.
- ¼ teaspoon sugar – This adds a slightly sweet touch that balances the richness.
- ¼ teaspoon Diamond Crystal kosher salt – Essential for enhancing flavors.
- ⅛ teaspoon freshly ground black pepper – For a dash of warmth and spice.
- 2 teaspoon milk – This makes the salad creamy.
- 2 tablespoon Japanese Kewpie mayonnaise – No substitutes here; its unique flavor is irreplaceable!
The perfect bread choice: Shokupan
For the best Japanese Egg Sandwich, the bread is just as crucial as the filling. I highly recommend using 4 slices of shokupan, the traditional Japanese milk bread. Its soft, fluffy texture and slightly sweet taste make it an ideal vessel for the luscious egg salad. If you’re feeling adventurous, try making homemade shokupan for an even fresher experience!
These little details may seem minor, but they make all the difference in achieving that authentic taste. Enjoy your sandwich-making adventure!
Step-by-step preparation of Japanese Egg Sandwich
Creating a delicious Japanese Egg Sandwich is a delightful endeavor that combines simple ingredients to produce a comforting meal. Let’s walk through this step-by-step guide to ensure your sandwich turns out perfectly!
Gather all your ingredients
Before you start, it's essential to gather everything you need. Here’s a quick checklist to help you:
- 3 large eggs (50 g each w/o shell)
- ¼ teaspoon sugar
- ¼ teaspoon Diamond Crystal kosher salt
- ⅛ teaspoon freshly ground black pepper
- 2 teaspoon milk
- 2 tablespoon Japanese Kewpie mayonnaise
- 4 slices of shokupan (Japanese milk bread)
- Salted butter
Having everything on hand will make the cooking process smoother and keep things organized.
Cook the eggs to perfection
Now, let’s tackle the heart of the Japanese Egg Sandwich — the eggs!
- Place the eggs in a medium saucepan and cover them with water by about an inch (2.5 cm).
- Bring the water to a boil over medium heat.
- Once boiling, let the eggs cook for 12 minutes. This step is crucial for achieving that perfect hard-boiled egg texture.
- After cooking, transfer the eggs to a bowl of iced water to cool completely. This stops the cooking process and makes peeling much easier.
- Once cooled, peel the eggshells off and set the whites and yolks aside.
Mash and season the egg salad
With your eggs ready, it’s time to create that luxurious egg salad filling.
- In a bowl, mash the peeled eggs using a fork until you have a mix of both smooth and small, uniform pieces.
- Add the sugar and kosher salt to enhance flavor.
- Sprinkle in the freshly ground black pepper and pour in the milk to make it creamy.
- Finally, mix in the Japanese Kewpie mayonnaise. This unique mayo is lighter and tangier than regular mayo, adding depth to your egg salad. Feel free to taste and adjust seasoning as necessary.
Assemble your sandwich with care
The assembly is where your Japanese Egg Sandwich starts to take shape:
- Lay out your shokupan bread slices.
- Spread a thin layer of salted butter on each slice. This not only adds flavor but also helps keep the bread from getting soggy.
- Generously spread the delicious egg salad on one slice, then place another slice buttered side down on top.
- To ensure the bread melds beautifully, press down slightly and let the sandwich sit for about five minutes.
Time to cut and serve!
Now that your sandwich is assembled, it’s time to make it visually appealing:
- Carefully trim the crusts off each sandwich — don't discard them! You can repurpose them into crunchy Shokupan Crust Rusks for a tasty snack later.
- Slice your sandwich into halves or quarters, depending on your serving preference.
And there you have it — a perfectly crafted Japanese Egg Sandwich! Serve it fresh for breakfast or as a delightful snack any time of day. Enjoy the simplicity and taste that this classic dish brings to your table.

Variations on the Japanese Egg Sandwich
Adding Turkey Bacon for Extra Flavor
If you’re looking to enhance your Japanese Egg Sandwich, consider adding crispy turkey bacon. The savory, smoky flavor complements the creamy egg salad beautifully. Simply cook the turkey bacon until it’s perfectly crispy, then layer it into your sandwich just before adding the egg salad. This addition not only elevates the taste but also adds a fun crunch!
A Veggie Twist with Added Greens
For those who prefer a healthier touch, try incorporating fresh greens like spinach or arugula into your Japanese Egg Sandwich. Just a handful will enrich the texture and add a pop of color. You might even consider spreading a layer of mashed avocado for a creamy, nutritious boost. This veggie twist keeps your sandwich light and refreshing, making it great for a quick lunch or snack!
Cooking tips and notes for Japanese Egg Sandwich
Choosing the right mayonnaise
When preparing your Japanese Egg Sandwich, opt for Kewpie mayonnaise. This unique Japanese mayo boasts a creamier texture and a slight sweetness that elevates your egg salad. If you can't find Kewpie, consider trying a homemade version for an authentic taste. Just remember, the right mayonnaise can make or break your sandwich!
Tips for perfectly cooked eggs
For flawless hard-boiled eggs, place your eggs in cold water, ensuring they’re covered by about an inch. Bring to a boil, then let them cook for exactly 12 minutes. Afterward, transfer them to ice water to stop the cooking process. This method yields tender, bright yellow yolks without any unpleasant greyness.
Following these tips will ensure your Japanese Egg Sandwich is a delightful experience packed with flavor!

Serving suggestions for Japanese Egg Sandwich
Pairing with a refreshing side salad
Elevate your Japanese Egg Sandwich by serving it with a vibrant side salad. A mix of crisp greens—like arugula and spinach—tossed with cherry tomatoes and a light vinaigrette complements the rich, creamy flavor of the sandwich. Consider adding some avocado slices for a touch of creaminess or mandarin orange segments for a hint of sweetness. This simple addition not only adds color but also balances the meal nutritionally.
Serving with homemade chips or snacks
For a more casual vibe, pair your Japanese Egg Sandwich with homemade chips or a selection of crunchy snacks. Thinly sliced vegetables, such as cucumbers and carrots, can offer a fresh crunch that contrasts beautifully with the softness of the sandwich. Think about whipping up some sweet potato chips or even a small bowl of edamame sprinkled with sea salt—both are fantastic choices that make your meal feel more complete.
