Make Breakfast Cool With These ‘Dinosaur Eggs’

Bring some prehistoric fun into the kitchen with these whimsical soft-boiled eggs.


Soft-boiled eggs are a staple in lunchboxes and at picnics. However, they look and taste pretty basic. I was trying to figure out a way to give them some more curb appeal and flavor when inspiration struck at the most unlikely moment. My five-year-old son and I were watching Jurassic Park. In one scene, the characters watch as dinosaur eggs hatch. Eureka! What kid wouldn’t want to eat dinosaur eggs?

To give the whites a similar mottled appearance, I decided to riff on what Westerners call ramen eggs, but the Japanese refer to as ajitsuke tamago. In my version, eggs are boiled for exactly seven minutes, so their sunny yolks have the consistency of thick lemon curd. After plunging the eggs into an ice bath to stop them from cooking further, I gently crack their shells, so there are hairline cracks all over them, but no major pieces have fallen off. Then I marinate the eggs for at least 12 hours in a mixture of soy sauce, mirin, seasoned rice wine vinegar, and water.

After removing them from the marinade and shucking off the shells, the whites have blotches of darkness and light with veins running across them. It’s not hard to imagine a baby T-Rex bursting out of one. Better still, they are now rich with a salty-sweet-umami flavor, which can even infuse the yolky core if you let them marinate long enough.

When these eye-catching eggs get pulled out at school or while picnicking with friends, they invariably garner intense interest from little ones. Though it sometimes takes a little convincing, most kids usually can’t wait to tear into one—usually while offering up a prehistoric roar. After all, who wouldn’t want to eat dinosaur eggs?

Breakfast ‘Dinosaur Eggs’

An overnight marinade gives these eggs a brown and white mottled surface. It’s not hard to imagine a baby T-Rex bursting out of one.

  • Yield: Makes 6 soft-boiled eggs


  • 6 large eggs
  • 1 cup water
  • 1 cup soy sauce
  • ½ cup mirin
  • ½ seasoned rice wine vinegar


  1. Step 1

    In a medium-sized bowl, mix together the water, soy sauce, mirin, and seasoned rice wine vinegar. Pour marinade into a large Ziploc bag and place inside another medium-sized bowl.

  2. Step 2

    Bring a medium-sized pot of water to a gentle boil, ensuring there is enough water to cover eggs by approximately 1 inch. Gently place eggs in boiling water using a slotted spoon or ladle, and boil eggs for exactly 7 minutes.

  3. Step 3

    Meanwhile, fill another medium-sized bowl with ice and cold water. When the eggs are finished cooking, remove them from the boiling water and place into the ice bath. Let rest for 2 minutes. Crack the eggs gently all over so they’re covered in cracks, but big pieces of shell haven’t come off.

  4. Step 4

    Place the eggs in the bag of marinade, ensuring all the eggs are completely covered. Place eggs in the refrigerator to marinate for at least 12 hours and up to 48.

  5. Step 5

    When you’re ready to eat them, remove the shells and quickly rinse them. The eggs are best enjoyed at room temperature. Eat them on their own, with a squirt of sriracha, or sprinkled with furikake.
