Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Fill a large bowl with ice water to create an ice bath. This will quickly cool the eggs after boiling, ensuring they stop cooking and are easy to peel. Set it aside while you prepare to boil the eggs for your delicious Japanese Egg Sandwich.
Step 2: Hard/Soft Boil Eggs
Bring a medium saucepan of water to a rolling boil over high heat. Carefully lower in the eggs using a slotted spoon. For medium soft-boiled eggs, boil for 7 minutes, then turn off the heat and let them sit for 1 minute. For hard-boiled eggs, boil for 10 minutes until fully cooked.
Step 3: Chill Eggs
Once the eggs are boiled to your desired doneness, transfer them immediately to the ice bath. Let the eggs cool for about 2 minutes; this shock prevents overcooking. After chilling, gently peel the eggs while they are still lukewarm, making the process easier and cleaner for your Japanese Egg Sandwich.
Step 4: Make Egg Salad
Place the peeled eggs in a mixing bowl and mash them with a fork until they reach a chunky consistency. Add 1/4 teaspoon each of sugar, salt, and pepper, along with 4 tablespoons of Japanese mayonnaise (and optional milk if using). Mix thoroughly until you achieve a creamy texture that is just right for your sandwich.
Step 5: Assemble Sandwiches
Lay out your 4 slices of Japanese milk bread on a clean surface. Spread softened butter generously on one side of each slice. Place a hearty scoop of the egg salad between two slices, pressing gently to secure the filling. Trim the crusts for a neater presentation and to enhance the softness of your Japanese Egg Sandwich.
Step 6: Serve
Carefully cut the assembled sandwiches in half for easier handling. Serve immediately while fresh and delicious, or wrap them up securely in plastic wrap for storage. Enjoy your delightful Japanese Egg Sandwich for lunch or as a light snack that everyone will adore!

Airtight Containers: Use airtight containers for storing any leftover egg salad; it will stay fresh for about 3 days in the fridge.
Reheating: If you’ve prepared the sandwich in advance, it’s best to eat it cold, but you can briefly microwave it (without plastic wrap) for about 10-15 seconds to warm up if preferred.

Creamy Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
How do I select the best eggs for the egg salad?
Absolutely! For the best flavor and creaminess in your Japanese Egg Sandwich, opt for high-quality eggs, like Pete and Gerry’s Organic Eggs. Look for eggs that are firm with no cracks, and opt for those with bright, vibrant yolks—these indicators often signal freshness. If you want to go a step further, consider free-range or pasture-raised eggs for richer taste.
What’s the best way to store leftover Japanese Egg Sandwiches?
To keep your sandwiches fresh, wrap each one tightly in plastic wrap and store them in the refrigerator. They’ll stay tasty for up to 2 days. For optimal freshness, consider storing the egg salad separately in an airtight container to prevent the bread from getting soggy until you’re ready to assemble.
Can I freeze Japanese Egg Sandwiches?
Yes, you can! To freeze, I recommend preparing the egg salad and storing it in an airtight container for up to 3 months. When you’re ready to indulge, simply thaw the egg salad in the refrigerator overnight, then assemble it with fresh bread. This method helps keep the sandwich from becoming soggy and maintains that lovely fluffy texture.
What if my egg salad turns out too dry or too wet?
If your egg salad is too dry, just add a teaspoon of milk or additional mayonnaise to reach the desired creaminess. On the other hand, if it’s too wet, you can try mashing in an extra hard-boiled egg to absorb some moisture. Mix gently, and taste as you go to achieve the perfect texture for your Japanese Egg Sandwich that will have everyone asking for more!
Are there any dietary considerations for this recipe?
Of course! If you have egg allergies, this sandwich won’t be suitable, but you can get creative with alternatives like mashed avocado or a chickpea salad for a similar texture. If you’re making it for children, be sure to check for any additional allergies to ingredients like mayo or dairy! As always, it’s good to customize based on dietary needs—everyone deserves a delicious meal!
How long does the egg salad last in the fridge?
The egg salad can last in the fridge for about 3 days if stored in an airtight container. Just be sure to give it a taste before using it, especially if it’s been a couple of days! I love making a larger batch and enjoying it throughout the week; it’s such a yummy, quick option for lunches or snacks!
