Japanese Egg Sandwich Ingredients
• Discover the essential elements for creating the perfect tamago sando!
For the Egg Salad
- Pete and Gerry’s Organic Eggs – Core ingredient, providing creamy texture and rich flavor; opt for the best eggs for superior taste.
- Sugar (1/4 teaspoon) – Enhances the flavor of the egg salad; skip this if using sweet mayo.
- Salt (1/4 teaspoon) – Essential for seasoning; adjust to taste after combining with mayonnaise.
- Ground Black Pepper (1/4 teaspoon) – Adds subtle spice; freshly ground will amplify the flavor.
- Milk or Plant Milk (1-2 teaspoons, optional) – Keeps hard-boiled egg salad moist; feel free to omit if using soft-boiled eggs.
- Japanese Mayonnaise (4 tablespoons) – Key to achieving authentic creaminess; substitute with regular mayo if needed, adjusting for flavor.
For the Sandwich
- Japanese Milk Bread (4 slices) – Provides a light, fluffy texture; if unavailable, high-quality white bread works too.
- Unsalted Butter (2 tablespoons, softened) – Perfect for spreading, adding richness; consider flavored butter for extra kicks.
- Chives (for garnish, optional) – Adds freshness and visual appeal; sprinkle over before serving.
Step‑by‑Step Instructions for Japanese Egg Sandwich
Step 1: Prepare Ice Bath
Fill a large bowl with ice water and set it aside. This will be used to cool the eggs quickly after boiling, which is essential for achieving perfectly cooked yolks and easy peeling. Having this ready beforehand will streamline your Japanese Egg Sandwich preparation.
Step 2: Boil Eggs
Bring a medium pot of water to a boil over high heat. Once boiling, gently lower in six organic eggs using a slotted spoon. For medium soft-boiled eggs, boil for exactly 7 minutes, then let them rest in the pot for an additional minute. If you prefer hard-boiled eggs, let them cook for 10 minutes before proceeding.
Step 3: Chill Eggs
After boiling the eggs, promptly transfer them to the ice bath using the slotted spoon. Chill the eggs for about 2 minutes to stop the cooking process. Once cooled, gently tap and roll the eggs on a countertop to crack the shell, making them easier to peel while still lukewarm.
Step 4: Make Egg Salad
In a large mixing bowl, mash the peeled eggs with a fork until you reach your desired consistency; a chunky texture works wonderfully for the Japanese Egg Sandwich. Add in sugar, salt, freshly ground black pepper, and Japanese mayonnaise, plus milk if you desire extra creaminess. Mix all ingredients thoroughly, tasting and adjusting seasoning as necessary.
Step 5: Assemble Sandwiches
Spread softened unsalted butter generously on one side of each slice of fluffy Japanese milk bread. Take one slice and spoon a generous amount of the creamy egg salad on top, distributing it evenly. Place another slice of bread on top, buttered side down, and press gently to compact the sandwich before trimming off the crusts for a polished finish.
Step 6: Serve
Carefully cut each sandwich in half diagonally for a beautiful presentation. If desired, garnish with chopped chives for added freshness and a pop of color. Arrange your delicious Japanese Egg Sandwiches on a plate and enjoy these creamy delights as a quick lunch or elevating meal experience!

-

Expert Tips for the Best Tamago Sando
Perfect Boiling Time: Use a timer to ensure your eggs are cooked consistently; 7 minutes for medium soft-boiled or 10 minutes for hard-boiled eggs is key for the Japanese Egg Sandwich.
Ice Bath Importance: Don’t skip the ice bath! It halts the cooking, helps maintain the yolk’s color, and makes peeling smoother.
Seasoning Adjustments: Taste your egg salad after mixing in the Japanese mayonnaise. Adjust sugar, salt, and pepper for a flavor that’s just right for you.
Bread Choice: Always choose high-quality Japanese milk bread for optimal texture. If unavailable, avoid very soft or dense breads to prevent sogginess.
Storage Tips: Keep sandwiches tightly wrapped and refrigerated for up to 2 days; however, they’re best enjoyed fresh for maximum creaminess and flavor.

Japanese Egg Sandwich (Tamago Sando) Recipe FAQs
What type of eggs should I use for the Japanese egg sandwich?
Absolutely! I recommend using high-quality organic eggs, like Pete and Gerry’s, as they provide a creamy texture and rich flavor that makes your egg salad truly special. Freshness matters, so look for eggs with a recent pack date for the best taste.
How should I store leftover Japanese egg sandwiches?
To maintain their fluffiness and flavor, wrap the sandwiches tightly in plastic wrap and place them in the fridge. Enjoy them within 2 days for the best experience. If you leave them at room temperature, they should be consumed within 2 hours.
Can I freeze Japanese egg sandwiches?
You can freeze the assembled sandwiches, but it’s best to do so for up to 1 month at most. Wrap each sandwich tightly in plastic wrap, then place them in a freezer bag. When you’re ready to enjoy, thaw them in the fridge overnight. Just know the bread texture might change, so it’s perfect if you’re not too picky!
What should I do if my eggs are difficult to peel?
If you find that your eggs aren’t peeling easily, it could be due to the freshness of the eggs. I suggest using slightly older eggs for boiling, as fresher eggs tend to bond more strongly with the shell. Also, remember to chill them promptly in an ice bath after boiling! For perfect results, tap each egg gently on a countertop to crack the shell, and then roll it with your palm before peeling.
Are there any dietary considerations for this recipe?
Certainly! If you have egg allergies, this recipe won’t be suitable, but you could experiment with an egg substitute, like tofu, for a creative twist. For a gluten-free option, use gluten-free bread. Just avoid any flavored mayonnaises if you’re concerned about allergies, and stick to basic ingredients to keep it safe for everyone.
How can I customize my Japanese egg sandwich?
Very! The recipe is wonderfully versatile. You can add finely chopped vegetables like cucumbers or radishes for a crunch, or even incorporate herbs like dill or parsley for a fresh flavor. Experiment with flavored mayonnaises, such as garlic or spicy versions, to elevate the taste. I often add a touch of wasabi mayonnaise for a little kick!
