Table of Contents
Toggle
If you’ve never had Korean marinated eggs, also known as Mayak Gyeran, you’re in for a treat. These soft, flavorful eggs are infused with a rich, garlicky, and slightly spicy soy-based marinade. They are incredibly versatile and can be enjoyed with rice, on toast, or as a side dish with ramen. Affordable and easy to prepare, these eggs will quickly become a staple in your kitchen.
I remember my first experience with them at a small restaurant in D.C., where they were served alongside ramen eggs in a profoundly satisfying broth. The taste was so unforgettable that I knew I had to recreate the flavors at home.
What Makes This Recipe Special
Soy-marinated eggs stand out for their incredible versatility. Whether enjoyed as a snack, a topping for ramen, or a flavorful addition to rice bowls and salads, they bring a deep umami richness to any dish. The combination of soy sauce and mirin infuses the eggs with a perfect balance of savory, sweet, and slightly salty notes. The yolk remains jammy and custard-like, while the whites stay firm, creating a delightful contrast in texture and taste.
Beyond their flavor, these eggs are easy to make and store. The longer they marinate, the richer and more complex their taste becomes. Whether following a traditional ajitsuke tamago method or personalizing the seasoning, you can tailor the recipe to your preference. Plus, by preparing multiple eggs in advance, you’ll always have a ready-to-eat, protein-packed option.

Soy marinated eggs (FAQs.)
1. How long should I marinate the eggs for the best flavor?
For optimal flavor, marinate the eggs for at least 2 hours. However, for a richer taste, marinating for 12-24 hours is ideal. If left too long (beyond 3-4 days), they may become overly salty.
2. Can I reuse the marinade for another batch of eggs?
You can reuse the marinade, but only if it remains clean and uncontaminated. If using it again, boil it first to kill bacteria and let it cool before reusing.
3. What’s the best way to achieve a jammy yolk?
For a soft-boiled, jammy yolk, cook the eggs for 6-8 minutes:
- 6 minutes: Runny yolk
- 7 minutes: Custard-like yolk
- 8 minutes: Firmer jammy yolk
Immediately placing the eggs in an ice bath stops the cooking process.
4. Can I use other sweeteners in the marinade?
Yes! You can substitute honey, sugar, or erythritol with rice or corn syrup for a deeper and richer sweetness.
5. How do I store soy-marinated eggs?
Store them in an airtight container in the refrigerator, fully submerged in the marinade, for 3-4 days. If removed from the marinade, they can last up to a week.
6. Can I make these eggs spicier?
Absolutely! Add more gochugaru (Korean chili flakes), jalapeño slices, or red chili peppers to the marinade to increase the heat.
7. What are the best ways to enjoy soy-marinated eggs?
They’re incredibly versatile! Try them:
- With ramen—for a restaurant-style topping
