Ingredients & Equipment
Ingredients
- 6 large Pete and Gerry’s Organic Eggs
- 1/4 teaspoon sugar
- 1/4 teaspoon salt
- 1/4 teaspoon ground black pepper
- 1 to 2 teaspoon milk (or plant milk (Optional) (Footnote 1))
- 4 tablespoons Japanese mayonnaise
- 4 slices Japanese milk bread
- 2 tablespoons unsalted butter (softened)
- chives (sliced) (for garnish) (Optional)
Footnote 1: The milk is optional and helps make the egg salad slightly creamier; plant milks like oat or almond work fine if you prefer dairy-free.
Equipment
- Medium saucepan (for boiling eggs) or steamer
- Bowl for mixing
- Fork or small whisk
- Knife and cutting board
- Spatula
- Fine sieve or ricer (optional, for extra-smooth filling)
- Blender (optional — pulse briefly for very smooth texture)
- Slotted spoon
- Timer and thermometer (helpful if you like precise doneness)
Tip: A simple egg slicer or a mesh ricer transforms the cooked eggs into a silky texture quickly. If you enjoy learning variations on egg texture, you might also look at a classic deviled egg recipe for ideas to riff on the seasoning.
Step-by-Step Instructions (with tips)
To make the egg salad
- Choose your method: Decide whether you want classic hard-boiled eggs, soft-boiled for an extra creamy center, or oven-baked eggs. For tamago sando, fully set yet tender yolks (jammy to fully hard) work best.
- Hard-boil method (recommended): Place 6 eggs in a single layer in a saucepan and cover with cold water by about an inch. Bring to a gentle boil, then cover, remove from heat, and let sit for 9–11 minutes depending on your stovetop and how set you like the yolks. Immediately transfer to an ice bath to stop cooking.
- Alternative — steaming: Steam eggs for 12 minutes for even, easy-to-peel shells. Steam often reduces surface cracking and gives predictably tender whites.
- Peel the cooled eggs and rough-chop them. For silkier consistency, push the chopped eggs through a fine sieve or pulse in a blender for one second bursts — avoid over-blending into paste.
- In a mixing bowl, combine chopped eggs, 4 tablespoons Japanese mayonnaise, 1/4 teaspoon sugar, 1/4 teaspoon salt, 1/4 teaspoon ground black pepper, and 1–2 teaspoons milk if using. Fold gently to keep some texture — tamago sando is known for being luxuriously smooth but not soupy.
- Taste and adjust: add a pinch more salt, a drop more mayo, or an additional 1/8 teaspoon sugar if you prefer a slightly sweeter profile (Japanese versions often balance sweet and savory).
- Optional garnish: Fold in finely chopped chives or reserve them to sprinkle on top of the assembled sandwich for a fresh note.
To cook and assemble the sandwich
- Prepare the bread: Lightly spread softened unsalted butter on one side of each slice of Japanese milk bread. The buttered side will sit against the egg filling for a richer mouthfeel and to keep the bread from becoming soggy.
- Toast (optional): For a warm contrast, lightly toast the bread on the buttered side just until golden. Traditional tamago sando often uses untoasted milk bread for its soft texture — choose what you love.
- Assemble: Spread a generous portion of egg salad onto the non-buttered side of one slice. Use a spatula to smooth it into an even layer about 1/2 inch thick; the goal is a cloud-like, pillowy profile rather than a thin smear.
- Top with a sprinkle of sliced chives if using, then place the second slice of bread on top, buttered-side down.
- Trim the crusts if you want the classic Japanese presentation: sandwiches are often crustless and cut into neat rectangles or triangles. Use a serrated knife and a gentle sawing motion to avoid squishing the filling.
- Slice and serve immediately: Tamago sando is best enjoyed the same day for maximum tenderness — the bread and filling are at their loveliest fresh.
To Store
If you have leftover egg salad, transfer it to an airtight container and refrigerate. Use within 3–4 days for best quality. If sandwiches are assembled ahead, store them wrapped tightly in plastic wrap or in an airtight container and consume within 24 hours to avoid soggy bread.
Variations & Kitchen Tips
Texture Variations
- Smoother filling: Push eggs through a mesh sieve or pulse briefly in a blender. Add milk by the teaspoon to adjust creaminess.
- Chunkier filling: Hand-chop eggs with a fork for more texture and mouthfeel.
- Roasted egg twist: For a smoky note, roast peeled eggs briefly under a broiler (watch carefully), then chop and mix — this adds a subtle depth.
Flavor Suggestions
- Swap Japanese mayo for your favorite brand, but note that Japanese mayonnaise (kewpie-style) has a tangier, richer umami profile that makes tamago sando special.
- Fold in a small amount of grainy mustard or wasabi mayonnaise for a spicy lift.
- Add a thin smear of sriracha mayo for a modern fusion version.
Storage, Freezing & Make-Ahead Tips
Egg salad doesn’t freeze well because the mayo and egg whites separate when thawed, so avoid freezing prepared sandwiches or egg salad. Instead, prep components:
- Make-ahead eggs: Hard-boiled eggs keep well in their shells for up to one week refrigerated — cook a batch and peel when ready to assemble.
- Make the egg salad up to 2 days in advance and keep it chilled in an airtight container. Stir gently before use to reincorporate any separated liquids.
- Assemble sandwiches the day you plan to serve. If you must transport them, wrap tightly in plastic wrap and pack in a cooler with an ice pack to maintain texture and safety.
- Portion advice: For meal prepping, portion the egg salad into 1/2-cup servings so you can quickly build sandwiches or use it as a topping for salads and toast.
How to Use / Serve This Dish
Tamago sando is wonderfully versatile. Serve a pair with a steaming bowl of miso soup for a Japanese-inspired breakfast, or pair with a light green salad and pickles for lunch. For a picnic, wrap sandwiches tightly and place on a bed of fresh lettuce to keep them from sticking.
Creative ways to use leftovers: Spread egg salad on avocado toast, use it as a filling for savory crepes, or top a baked potato with a spoonful for lunch. If you enjoy repurposing egg dishes into snacks, check this variety demonstrating a fun cooked twist on egg ideas like air fryer deviled eggs.
FAQ
How long will homemade tamago sando stay fresh?
Assembled sandwiches are best eaten the same day. If stored, keep them in the refrigerator and eat within 24 hours to preserve bread texture. Egg salad alone keeps 3–4 days refrigerated in an airtight container.
Can I substitute regular mayonnaise for Japanese mayonnaise?
Yes — you can use regular mayonnaise, but the flavor profile will differ. Japanese mayonnaise (kewpie style) is tangier and richer because it often uses only egg yolks and a different vinegar. If you want to emulate the taste, add a touch of rice vinegar and a pinch of sugar to regular mayo.
What’s the best way to get perfectly cooked eggs for the filling?
Steaming eggs for about 12 minutes or using the stovetop sit-and-steam method (bring to boil, cover and rest 9–11 minutes) produces even, easy-to-peel eggs with tender whites and set yolks. Immediately chilling in an ice bath helps prevent overcooking and makes peeling easy.
Any good substitutions for milk bread?
Japanese milk bread is ideal for its soft, slightly sweet crumb. If you can’t find it, use brioche or a very soft sandwich bread. Toasted sourdough gives a delicious contrast but changes the traditional texture.
