Korean Marinated Eggs (Mayak Eggs) – Easy Gyeran jang

Korean Soy Marinated Eggs (Mayak Eggs)

If you’ve ever wanted a Korean side dish that feels like a magic trick—minimal effort, maximum flavor—this is it. Korean marinated eggs are tender, savory, gently sweet, and wildly satisfying over a bowl of hot rice.

What makes them especially home-cook friendly is the “set it and forget it” method: boil eggs, mix a quick soy marinade, add chopped veggies, and let the fridge do the work.

They’re also a smart meal-prep staple. Make a batch once, and you’ve got an instant upgrade for rice bowls, lunchboxes, and quick weeknight dinners all week.

What is Korean Soy Marinated Eggs?



Korean Soy-Marinated Eggs, or Gyeran Jang, are a popular variety of banchan (Korean side dishes) featuring soft-boiled eggs steeped in a flavorful soy-based marinade. The term "Mayak Eggs" (마약 계란장) highlights their irresistibly delicious and addictive quality. The marinade typically consists of soy sauce, water, a sweetener, sesame oil, and various finely chopped vegetables like onions, bell peppers, and fresh chili peppers, along with toasted sesame seeds.

The magic lies in the contrast: a perfectly cooked egg yolk that remains soft and creamy, absorbing the rich, savory, and subtly sweet notes of the marinade. The fresh vegetables add a delightful crunch and brightness, making these easy Korean eggs a perfect complement to any meal, especially a bowl of warm rice.

It tastes like you put in way more effort than you actually did.

Need a reliable Korean side dish that makes the whole table feel more exciting? This is the one that disappears first—usually with someone asking, “Did you make more?”

Ingredients

Yields: 8 eggs
Prep time: 15 minutes
Marinating time: 6-12 hours

For the Eggs:

  • 8 large eggs
  • 1 teaspoon salt (for boiling water)

For the Marinade:

  • 1/2 cup soy sauce
  • 1/2 cup water
  • 2 tablespoons oligosaccharide (or corn syrup)
  • 1 tablespoon granulated sugar
  • 1 tablespoon sesame oil
  • 2 tablespoons toasted sesame seeds
  • 1/2 teaspoon black pepper

For the Vegetables (finely chopped):

  • 1/2 medium onion
  • 1/2 red bell pepper
  • 1/2 yellow bell pepper
  • 1 green chili pepper (such as Korean green pepper or jalapeño, deseeded for less heat)

Method / Instructions

Follow these simple steps to create your own batch of delightful Korean Soy-Marinated Eggs:

  1. Boil the Eggs:

    In a medium pot, bring enough water to a rolling boil to fully submerge the eggs. Add 1 teaspoon of salt to the water. Carefully lower the eggs into the boiling water and cook for 6 minutes for perfect soft-boiled eggs with a runny yolk. If you prefer a slightly firmer yolk, cook for 7 minutes.



  2. Prepare an Ice Bath: While the eggs are boiling, prepare an ice bath by filling a bowl with cold water and ice cubes.
  3. Chill and Peel Eggs:

    Immediately after cooking, transfer the eggs from the boiling water to the ice bath. Let them cool for about 5-10 minutes. This stops the cooking process and makes them easier to peel. Gently tap and roll the eggs to crack the shells, then carefully peel them under cold running water. Set aside.
  4. Chop Vegetables: Finely dice the onion,

    red bell pepper, yellow bell pepper,

    And green chili pepper.

    Ensure the pieces are small so they can easily infuse the marinade and cling to the eggs.

  5. Prepare the Marinade: In a mixing bowl, combine the soy sauce, water, oligosaccharide (or corn syrup), granulated sugar, sesame oil, toasted sesame seeds, and black pepper. Whisk until the sugar is fully dissolved.

  6. Combine Marinade and Vegetables: Add the finely chopped vegetables to the liquid marinade and stir to combine evenly.
  7. Marinate the Eggs: Place the peeled soft-boiled eggs gently into an airtight container. Pour the prepared marinade with vegetables over the eggs, ensuring they are mostly submerged. You may need to gently turn the eggs occasionally to ensure even marination.

  8. Refrigerate: Cover the container and refrigerate for a minimum of 6 hours, or preferably 12 hours, to allow the flavors to fully develop. These marinated eggs are best after a full night of marinating.
  9. Serve: When ready to eat, gently spoon an egg or two onto a plate, along with some of the vegetable-rich marinade. Serve immediately with warm rice or as a delicious Korean side dish.

Tips, Variations, and Serving Suggestions

Think of the marinade as your “choose-your-own-adventure” sauce. If you like things bright and crunchy, dice the vegetables small and generous so every spoonful has a little bite. If you want it calmer and sweeter, go a touch lighter on the chili and let the sesame oil do the cozy, nutty heavy lifting.

The eggs are the real main characters, though—and timing is their personality. Pull them at around 6 minutes and you get that soft, velvety center that turns a warm bowl of rice into instant comfort. Go a minute longer and the yolk firms up slightly, still tender, but a little neater if you’re packing lunch or serving guests.

When it’s time to eat, the simplest serving is often the best: hot rice, one Korean Soy-Marinated Egg, and a spoonful of that vegetable-studded sauce. Stir it together and you’ve got something that tastes like a complete meal with almost no effort. If you’re building a bigger spread, tuck these eggs alongside other Korean side dishes (internal link: Banchan recipes) or add them to a quick weeknight bowl with vegetables and your favorite protein.

One small habit that makes everything better: every time you open the container, gently turn the eggs so they marinate evenly. It’s a tiny move, but it’s how you end up with that “every bite is flavorful” kind of satisfaction—the kind that makes you wander back to the fridge for “just one more.”

Frequently Asked Questions

Can I use hard-boiled eggs for Korean Soy-Marinated Eggs?
You can, but traditional Korean soy-marinated eggs are made with soft-boiled eggs. The slightly runny yolk is a signature feature and absorbs the marinade more richly than fully cooked yolks.
How long do Korean Soy-Marinated Eggs last in the refrigerator?
Stored in an airtight container and fully submerged in the marinade, they keep well for up to 7 days in the refrigerator. The flavor deepens noticeably after the first day or two.
What if I don’t have oligosaccharide?
You can substitute with an equal amount of corn syrup, or use a slightly smaller amount of granulated sugar. Start with about 1½ tablespoons and adjust to taste to balance the savory soy sauce.
Can I make Korean Soy-Marinated Eggs less salty?
Yes. Reduce the soy sauce slightly and increase the water, or use a low-sodium soy sauce. Keep in mind the eggs absorb seasoning over time, so they will taste saltier the longer they sit.
What are some ways to enjoy Gyeran Jang?
Gyeran Jang is delicious with a bowl of warm rice, where the marinade doubles as a sauce. It also works well as a snack, on toast, or chopped and added to noodle dishes.
