Japanese Egg Sandwich Ingredients
For the Egg Salad
• Pete and Gerry’s Organic Eggs – High-quality, fresh eggs are essential for flavor; substitute with any organic free-range eggs.
• Sugar – Adds a hint of sweetness, balancing flavors in the egg salad; no substitutions necessary.
• Salt – Enhances overall taste; adjust according to preference.
• Ground Black Pepper – Adds spice; adjust to taste.
• Milk (Optional) – Keeps the egg salad moist, particularly useful if using hard-boiled eggs; plant-based milk can be used as a substitute.
• Japanese Mayonnaise – Provides a richer flavor and creamier texture compared to regular mayo; use regular mayonnaise if unavailable, but note it will alter the taste.
For the Sandwich
• Japanese Milk Bread – Soft, sweet bread that complements the egg filling; substitute with high-quality white bread if needed, ideally one with a spongy texture.
• Unsalted Butter – Enhances flavor and helps bind the sandwich; can substitute with vegan butter or omit for a lighter version.
• Chives (Optional) – Adds color and a mild onion flavor for garnish.
Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Start by filling a medium-sized bowl with ice and water to create an ice bath. This will help cool the boiled eggs quickly and make peeling easier. Set it aside while you prepare to boil the eggs for your Japanese Egg Sandwich.
Step 2: Boil Eggs
Bring a pot of water to a gentle boil over medium heat. Carefully add your Pete and Gerry’s Organic Eggs to the boiling water. For medium soft-boiled eggs, cook for 7 minutes, and for hard-boiled eggs, let them simmer for 10 minutes. Watch the time closely for the perfect texture!
Step 3: Cool Eggs
Once the eggs are done boiling, immediately transfer them into the prepared ice bath using a slotted spoon. Allow the eggs to sit in the ice water for about 2 minutes. This cooling step will stop the cooking process and ensure you achieve that ideal creamy yolk for your tamago sando.
Step 4: Mash Eggs
After 2 minutes, gently tap the eggs on a hard surface to crack the shell, and peel them under running water to make it easier. Once peeled, place the eggs in a mixing bowl and mash them roughly with a fork, leaving some texture. Mix in sugar, salt, pepper, and Japanese mayonnaise, adding milk if you desire a creamier filling.
Step 5: Assemble Sandwich
Take your Japanese milk bread and spread a thin layer of unsalted butter on one side of each slice. Generously spoon the creamy egg salad onto one slice, then top with another slice of bread, butter side down. Trim off the crusts for a tidy presentation if you’d like!
Step 6: Serve
Using a sharp knife, cut the assembled Japanese Egg Sandwich in half diagonally for easy handling. Serve fresh, and enjoy the delightful combination of flavors and textures in every bite. This simple yet satisfying sandwich is perfect for lunch or as a flavorful snack!

Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
How do I choose the right eggs for my egg salad?
Absolutely! For the best flavor, I recommend using high-quality fresh eggs, like Pete and Gerry’s Organic Eggs. Their taste is superior and will elevate your tamago sando. If you can’t find those, any organic free-range eggs will work just fine, ensuring your egg salad is delightful and rich!
How should I store leftover sandwiches?
Very good question! Wrap any assembled Japanese Egg Sandwiches in plastic wrap; this helps them stay fresh in the fridge for up to 2 days. It’s essential to seal them well to prevent them from drying out. Make sure they’re kept in a cool section of your fridge, like the main compartment.
Can I freeze the egg salad for later use?
Yes, you can! To freeze, separate the egg salad mixture into an airtight container. It will stay good for up to 3 months. When you’re ready to enjoy, simply thaw it in the fridge overnight, then give it a stir before you assemble it with your bread.
What should I do if my egg salad is too dry?
If your egg salad turns out dry, don’t fear! Mix in a splash of milk or an extra scoop of Japanese mayonnaise to get that creamy texture back. If you’re using hard-boiled eggs, this step is particularly beneficial for adding moisture.
Can I make this sandwich for kids with allergies?
Definitely! These sandwiches can be customized to cater to various dietary needs. For egg allergies, unfortunately, the eggs are vital to the recipe, but if you’re concerned about dairy or gluten, consider using vegan mayo and gluten-free bread. Making the sandwich with softer ingredients can allow for a nice texture without compromising flavor.
How can I tell if my eggs are fresh?
Absolutely a great point to consider! To check egg freshness, you can do a simple water test: place an egg in a bowl of water. If it sinks and lays flat on the bottom, it’s fresh. If it stands upright or floats, it’s best to toss it. Always prioritize using the freshest ingredients for your tamago sando!
