Experience the delightful simplicity of a Japanese egg salad sandwich. This classic sandwich combines the creamy texture of Japanese mayonnaise with the rich flavor of hard-boiled eggs, all nestled between soft slices of white bread. Perfect for a quick lunch or a light snack, this recipe is sure to become a favorite.
One key ingredient that might not be commonly found in your pantry is Japanese mayonnaise. Unlike regular mayonnaise, Japanese mayonnaise has a richer, slightly tangy flavor and a creamier texture. You can find it in the Asian foods section of most supermarkets or at specialty Asian grocery stores.

Ingredients for Japanese Egg Salad Sandwich
Eggs: These are the main ingredient, providing protein and a rich, creamy texture when mashed.
Japanese mayonnaise: This gives the egg salad its unique, slightly tangy flavor and creamy consistency.
White bread: Soft and fluffy, it serves as the perfect base for the egg salad.
Salt: Enhances the overall flavor of the egg salad.
Pepper: Adds a hint of spice and depth to the mixture.
Technique Tip for This Recipe
For a creamier texture, consider using a potato masher instead of a fork to mash the eggs. This will ensure that the egg mixture is smooth and well-blended, making your sandwich filling more cohesive and easier to spread.

japanese mayonnaise - Substitute with regular mayonnaise: Regular mayonnaise can be used in place of Japanese mayonnaise, though you might want to add a bit of rice vinegar and a pinch of sugar to replicate the slightly tangy and sweet flavor.
white bread - Substitute with whole wheat bread: Whole wheat bread provides more fiber and nutrients, making it a healthier option while still maintaining a similar texture.

How To Store / Freeze This Recipe
- Allow the egg salad mixture to cool completely before storing. This helps maintain the texture and prevents condensation from making the bread soggy.
- Store the egg salad mixture separately from the bread if you plan to keep it for more than a few hours. This keeps the bread fresh and prevents it from becoming soggy.
- Place the egg salad mixture in an airtight container. Ensure the container is sealed tightly to maintain freshness and prevent any odors from other foods in the fridge from seeping in.
- If you have already assembled the sandwiches, wrap each one individually in plastic wrap or aluminum foil. This helps keep the sandwiches together and prevents them from drying out.
- Store the wrapped sandwiches or the airtight container with the egg salad mixture in the refrigerator. They can be kept fresh for up to 2 days.
- For longer storage, consider freezing the egg salad mixture separately. Place it in a freezer-safe container or a resealable plastic bag, removing as much air as possible before sealing.
- Label the container or bag with the date to keep track of freshness. The egg salad mixture can be frozen for up to 1 month.
- When ready to use, thaw the egg salad mixture in the refrigerator overnight. Avoid thawing at room temperature to prevent bacterial growth.
- Once thawed, give the egg salad mixture a good stir to reincorporate any separated ingredients. Assemble the sandwiches as per the original recipe instructions.
- If you prefer a fresher taste, toast the bread lightly before assembling the sandwiches. This adds a delightful crunch and helps maintain the bread's texture.
How To Reheat Leftovers
Preheat your oven to 350°F (175°C). Wrap the sandwiches in aluminum foil to prevent them from drying out. Place them on a baking sheet and heat for about 10-15 minutes until warmed through.
Use a toaster oven set to 350°F (175°C). Place the sandwiches directly on the rack or on a baking sheet. Heat for 10-12 minutes, checking occasionally to ensure they don't get too crispy.
For a quick method, use a microwave. Place the sandwiches on a microwave-safe plate and cover with a damp paper towel to retain moisture. Heat on medium power for 1-2 minutes, checking halfway through.
If you have a panini press or sandwich maker, preheat it and place the sandwiches inside. Heat for 3-5 minutes until the bread is crispy and the filling is warmed.
For a stovetop method, heat a non-stick skillet over medium heat. Place the sandwiches in the skillet and cover with a lid. Heat for 2-3 minutes on each side until the bread is golden and the filling is warm.
