Ingredients

The Japanese Egg Sandwich requires just a few simple ingredients:

  • 4 large eggs
  • 3 tablespoons Japanese mayonnaise (or regular mayo if unavailable)
  • 1 tablespoon butter (optional, for extra richness)
  • 1 teaspoon Dijon mustard (optional)
  • 4 slices of soft white bread (Japanese milk bread works best)
  • Salt and pepper to taste
  • Fresh herbs (optional, for garnish)

Ingredient Highlights

  • Japanese Mayonnaise: Known for its smoother, slightly tangier taste, Japanese mayo (like Kewpie) adds a unique flavor to the egg filling. If you can’t find it, regular mayo will work, but the taste may differ slightly.
  • Soft White Bread: The bread should be fluffy and light. Japanese milk bread is ideal for its soft, pillowy texture, but any soft white bread will do.
  • Butter: Adds richness and a silky texture to the egg filling, making it extra creamy.

Step-by-Step Instructions

Cook the Eggs

  1. Boil the Eggs: Start by boiling the eggs. Place them in a pot of cold water, bring it to a boil, then reduce the heat and let them simmer for about 10 minutes for hard-boiled eggs. Once done, transfer the eggs to an ice bath or run them under cold water to cool.
  2. Peel and Mash: Once the eggs are cool, peel them and chop them roughly. Then, mash them with a fork until they are broken into small, uneven pieces.

Prepare the Filling

  1. Mix the Filling: In a mixing bowl, combine the mashed eggs with Japanese mayo, butter, mustard (if using), salt, and pepper. Stir everything together until the mixture is smooth and creamy. Taste and adjust the seasoning to your liking.

Assemble the Sandwich

  1. Prepare the Bread: If desired, trim the crusts off the bread to give it that soft, clean look (this is optional but often done in Japan for a more refined presentation).
  2. Spread the Filling: Generously spread the egg mixture onto two slices of bread, making sure to cover the entire surface.
  3. Close the Sandwich: Place the remaining two slices of bread on top and press gently to seal.

how to Serve

  1. Cut and Serve: Slice the sandwich in half or into quarters, and serve immediately. If you’re preparing it in advance, wrap it tightly to keep it fresh.

Additional Tips

  • Use the Right Bread: For the fluffiest, most authentic sandwich, opt for soft, squishy bread, like Japanese milk bread (Shokupan). It’s slightly sweet and holds the creamy filling beautifully.
  • Add Extra Flavor: If you like a little kick, add a pinch of wasabi to the egg filling or top with a sprinkle of paprika.
  • Make It a Meal: Pair the sandwich with a small salad or some pickles on the side to round out the meal.

Recipe Variations

Here are some fun twists on the classic Japanese Egg Sandwich:

  • Avocado Twist: Add mashed avocado to the egg filling for a creamy, fresh taste.
  • Lettuce: Add a layer of fresh lettuce to the sandwich for extra crunch and freshness.
  • Bacon: Crisp bacon can be added for a smoky flavor that complements the creamy egg filling.
  • Vegan Option: Try using tofu or chickpea-based egg salad as a substitute for the traditional egg filling.

Freezing and Storage

While the Japanese Egg Sandwich is best enjoyed fresh, you can store it for later if needed:

  • Storage: Keep the sandwiches in an airtight container in the fridge for up to 1 day. They might lose some of their freshness but will still be tasty.
  • Freezing: It’s not ideal to freeze this sandwich, as the filling and bread may become soggy upon thawing.

Special Equipment

You don’t need much, but these tools will help make the process smoother:

  • Pot: For boiling the eggs.
  • Mixing Bowl: To combine the egg filling.
  • Knife: To chop the eggs and cut the sandwich.
  • Platter: To serve the sandwiches in style.
  • Whisk or Electric Mixer: A whisk or a hand mixer can help blend the egg mixture smoothly when you add the mayo and seasonings.
  • Non-stick Pan: If you’re making the egg filling in a pan (soft scrambled), a non-stick pan is a great choice to prevent sticking and ensure a smooth texture for the eggs.
  • Knife: A sharp knife is essential for cutting the sandwich into neat, uniform slices. This is especially important if you’re looking to serve your sandwich like a bento box or for a party.
  • Bread Knife: If you prefer to trim the crusts off your sandwich to achieve that soft, square presentation, a serrated bread knife is best for cutting without squashing the bread.
  • Plastic Wrap: Use plastic wrap to keep your sandwich fresh and prevent it from drying out if you’re preparing it ahead of time.
  • Sandwich Press (Optional): If you want your sandwich to be slightly toasted or pressed for a bit of crunch, a sandwich press can be used. However, this is optional as the traditional version is served as is.
  • Bento Box: If you’re planning to serve the sandwich as part of a bento box, having a compact and neat bento box will help present the sandwich beautifully.

FAQ Section

Got questions about making the Japanese Egg Sandwich? You’re not alone! This simple, creamy sandwich is easy to prepare, but there might still be a few things you’d like to know before diving into the recipe. Below, I’ve answered some of the most common questions to help you out.

Soft, fluffy white bread works best for this sandwich. If you have access to Japanese milk bread (Shokupan), it’s perfect because of its sweetness and soft texture. However, any soft white bread can do the trick!

Can I use regular mayonnaise instead of Japanese mayo?

Yes, regular mayo will work in a pinch! However, Japanese mayonnaise (like Kewpie) has a slightly tangier, smoother taste, which adds to the unique flavor of this sandwich. If you can find it, I definitely recommend giving it a try!

How do I keep the bread soft?

Use fresh, soft white bread (Japanese milk bread is ideal). If your bread is a little too firm, you can wrap it in a damp paper towel and microwave it for a few seconds to soften it before assembling the sandwich.

Can I add extra ingredients to the egg filling?

Absolutely! The filling is versatile. You can add:

Fresh herbs like chives or dill for extra flavor.

A little mustard for a tangy kick.

A sprinkle of paprika or chili flakes for some spice.

Mashed avocado for a creamy texture.

A dash of wasabi if you’re feeling adventurous!

Is it okay to make the sandwich in advance?

While the sandwich is best enjoyed fresh, you can make it ahead and store it in the fridge for up to 1 day. Just wrap it tightly to prevent the bread from drying out.

Can I freeze the sandwich for later?

Freezing is not recommended as it can make the bread soggy when thawed. The sandwich tastes best when freshly made.
