Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prep Ice Bath
Fill a large bowl with ice and water to create an ice bath. This will be essential for cooling the eggs rapidly after boiling, ensuring they stop cooking immediately and maintain the perfect texture. Set this bowl aside as you prepare to boil your eggs for the creamy Japanese Egg Sandwich.
Step 2: Boil Eggs
In a medium pot, bring water to a gentle boil over medium-high heat. Carefully add the Pete and Gerry’s organic eggs, lowering them in gently to prevent cracking. For medium soft-boiled eggs, cook them for about 7 minutes; if you prefer hard-boiled, let them simmer for 10 minutes until set.
Step 3: Chill and Peel
Once the cooking time is complete, use a slotted spoon to transfer the eggs to the prepared ice bath. Let them sit for 2 minutes to cool down, which will make peeling easier. Once cool but still slightly warm, gently tap the eggs to crack the shell, then peel them carefully to avoid any damage.
Step 4: Make Egg Salad
In a mixing bowl, mash the peeled eggs with a fork until they reach your desired creaminess—still slightly chunky works well for a great texture. Add in the sugar, salt, ground black pepper, and Japanese mayonnaise (and optional milk for moisture). Mix everything together until it’s rich and creamy, showcasing the flavors for your Japanese Egg Sandwich.
Step 5: Assemble Sandwich
Take the soft Japanese milk bread slices and spread the softened unsalted butter on one side of each slice. On one slice, heap a generous portion of the creamy egg salad, then top it with another slice of bread, buttered side down. Press gently, trim the crusts for a neat look, and cut the sandwich in half to reveal the delicious filling.
Step 6: Serve or Store
Serve the irresistibly creamy Japanese Egg Sandwich right away for the best experience, or wrap it tightly in plastic wrap to refrigerate for up to 2 days. If preparing in advance, keep the egg salad separate and assemble the sandwiches just before serving to maintain that delightful bread texture.

Expert Tips for Japanese Egg Sandwich
- Quality Matters: Use fresh, high-quality eggs for the best flavor in your Japanese Egg Sandwich; this makes a noticeable difference in taste.
- Egg Timing: Perfect the cooking time to avoid overcooking; 7 minutes for soft-boiled or 10 minutes for hard-boiled eggs will yield ideal results.
- Cooling Process: Don’t skip the ice bath! It stops the cooking process instantly, ensuring a tender egg texture and perfect yolks.
- Mixing Technique: Aim for a creamy yet slightly chunky egg salad; over-mixing can lead to a pasty consistency.
- Assembly Tip: For optimal freshness, keep the egg salad separate from the bread if preparing in advance; assemble your Japanese Egg Sandwich just before serving.
How to Store and Freeze Japanese Egg Sandwich
Fridge: Store assembled Japanese Egg Sandwich in an airtight container for up to 2 days. This helps maintain the bread’s freshness while keeping the egg salad creamy.
Egg Salad (Pre-Made): Make the egg salad in advance and refrigerate it for up to 3 days. Assemble the sandwiches just before serving for the best texture.
Freezer: For longer storage, freeze the egg salad (without bread) in an airtight container for up to 2 months. Thaw in the fridge overnight before using.
Reheating: If you prefer warm sandwiches, reheat the egg salad gently in a microwave or on the stove, but avoid overheating to keep the texture lovely and creamy.

Make Ahead Options
These Japanese Egg Sandwiches are a fantastic choice for meal prep enthusiasts! You can make the egg salad up to 24 hours in advance to save time on busy days. Simply boil and peel the eggs, then mash them with the other ingredients like Japanese mayonnaise and seasoning. Store the egg salad in an airtight container in the refrigerator to keep it fresh. However, it’s best to assemble the sandwiches just before serving to preserve the texture of the Japanese milk bread, ensuring it remains soft and fluffy. This way, you’ll enjoy your delicious Japanese Egg Sandwich with minimal effort, just as delightful as if you made it fresh!

Japanese Egg Sandwich Recipe FAQs
How do I choose the right eggs for my Japanese Egg Sandwich?
Absolutely! It’s best to use high-quality eggs, such as Pete and Gerry’s Organic Eggs, as they provide rich flavor and a beautiful texture for your egg salad. Look for eggs that are firm, clean, and without any cracks—a little love in the selection process goes a long way!
What is the best way to store leftover Japanese Egg Sandwich?
To keep your sandwich fresh, store it in an airtight container in the fridge for up to 2 days. If you prepare the egg salad in advance, it can remain fresh for up to 3 days, but wait to assemble the sandwich until just before you’re ready to eat to avoid soggy bread.
Can I freeze the egg salad for my Japanese Egg Sandwich?
Yes! For long-term storage, you can freeze the egg salad (without the bread) in an airtight container for up to 2 months. When you’re ready to enjoy it, simply thaw it in the fridge overnight. Just remember to give it a good stir after thawing, as the texture may slightly change during freezing.
What should I do if my egg salad turns out too runny?
Very! If your egg salad is too runny, try adding a bit more mayonnaise or a sprinkle of finely crushed crackers to absorb the excess moisture. Alternatively, mix in a small amount of very finely chopped boiled potatoes to thicken the mixture. Adjusting the consistency can make all the difference for your Japanese Egg Sandwich.
Are there any dietary considerations with the ingredients in the Japanese Egg Sandwich?
If you have dietary restrictions, it’s important to note that Japanese mayonnaise contains eggs, so make sure to choose a suitable alternative like vegan mayo if you’re avoiding eggs altogether. Be cautious with potential allergens—always check your ingredient labels for any hidden sources of allergies, especially gluten in bread or sodium content in mayonnaise substitutes.
How can I add more flavor to my Japanese Egg Sandwich?
You can enhance the flavor by incorporating fresh herbs like chives or dill into your egg salad. If you crave extra crunch, adding thinly sliced cucumber or pickles works wonders. Another tip is to experiment with seasonings—try a hint of smoked paprika or a dash of sriracha for a spicy twist. The more, the merrier when it comes to customizing your Japanese Egg Sandwich!
