What are mayak eggs?

Korean mayak eggs (or mayak gyeran) are boiled eggs marinated in a flavourful soy sauce-based mixture. The marinade often includes soy sauce, water, sugar, and various aromatics such as garlic, green onions, and chilli peppers.

They’re a popular snack or side dish (banchan) in Korean cuisine, known for their savoury, slightly sweet taste and attractive dark colour.

Mayak means illicit in the context of drugs. Which is why they are also called drug eggs. The name is a playful nod to the irresistible and addictive flavour of these marinated eggs, which keep you coming back for more. Something I can certainly confirm.

Korean marinated eggs ingredients and substitutes

This mayak egg recipe is flexible and super easy to make. And if you cook lots of Asian food, you most likely have enough ingredients in the pantry to start your first batch of Korean eggs today.

For the soft-boiled eggs

Use large eggs at room temperature. Fridge-cold eggs may crack when they hit the rapidly boiling water. They also lower the water temperature resulting in runny egg whites. 

If you have eggs in the fridge but you’re in a hurry to start your delicious soy-marinated eggs, you can use a bowl of warm water to heat the eggs. Simply place refrigerated eggs in hot tap water for a few minutes to bring them to room temperature quickly.

I prefer jammy eggs (cooked for 6 minutes) for marinating, but you can also use hard-boiled. Use the same method outlined in the mayak egg recipe, but cook the eggs for 10 minutes.

Egg marinade ingredients

  • Soy sauce: Use light soy sauce or all-purpose soy sauce for the marinade base. You can also add a tablespoon of dark soy sauce for a deeper colour and stronger flavour. Use tamari or coconut aminos for a gluten-free marinade.
  • Toasted sesame oil: It adds a nutty, toasted flavour. If you don’t have any, you can omit it. The oil serves no purpose in the marinade other than flavour.
  • Honey: I adore honey. And here it adds a subtle sweetness to counterbalance the saltiness of the soy sauce. You can use your preferred sweetener. Try it with maple syrup, brown rice syrup, corn syrup, or brown sugar instead. 
  • Sesame seeds: Use normal hulled sesame seeds. You can toast the sesame seeds for a deeper flavour (especially if you omit the toasted sesame oil). 
  • Garlic: Use fresh garlic cloves for the best flavour. 
  • Green onions: If you don’t have green onions (scallions) or spring onions, use chives or finely chopped shallots or regular onions. 
  • Chilli peppers (optional): I like to use two Thai bird’s eye chilli peppers for a fiery kick. But I often make these eggs without the chilli. And instead, I sprinkle the marinated eggs with a pinch of gochugaru (Korean chilli flakes). You can use your preferred fresh chillies or red pepper flakes to match your heat tolerance or omit them altogether.

Store the marinated eggs (removed from the marinade) in an airtight container in the fridge for up to 4 days. Enjoy the eggs cold, or let them come to room temperature before serving. 

How to make Korean mayak eggs

The key to perfect jammy eggs is to use room temperature eggs and cook them for just 6 minutes – this will give you scrumptiously soft-boiled eggs that are perfect for marinating. And be sure to prepare an ice water bath to avoid overcooking the eggs.

How to make mayak eggs by marinating the soft-boiled eggs in a soy-based marinade.

Step 1: Boil the eggs

Prepare your ice bath before you cook the eggs. Grab a large bowl that can fit all your eggs. Add a few handfuls of ice cubes with enough water to submerge the boiled eggs. 

Take a medium-sized pot big enough to fit the eggs in a single layer. Fill it half full with water and bring it to a boil over medium-high heat. Once the water reaches a rolling boil, stir in the tablespoon of white vinegar and one teaspoon of salt. 

Gently place the room-temperature eggs in the boiling water with a slotted spoon. Start a timer once the last egg hits the water and cook for six minutes for jammy eggs (or ten minutes for hard-boiled eggs). 

Transfer the eggs to the waiting ice bath and cool down for five minutes.

Gently tap the cooled eggs a few times on a flat surface and softly roll the eggs with the palm of your hand to crack the shell all over. Then peel the eggs, and rinse off any pieces of eggshell. Or use your own trusted egg peeling technique.

Step 2: Make the egg marinade

Add all the ingredients for the soy-based egg marinade in a small bowl: 

  • half a cup of light soy sauce (or all-purpose soy sauce), 
  • one tablespoon of dark soy sauce (optional), 
  • one tablespoon of toasted sesame oil (optional), 
  • a quarter cup of honey, maple syrup or brown rice syrup, 
  • one tablespoon of sesame seeds (toasted for extra flavour), 
  • two minced garlic cloves
  • two thinly sliced green onions
  • and two sliced chilli peppers if you want spicy Korean eggs.

Whisk until the honey is fully incorporated. 

Step 3: Marinate the eggs

Place the peeled eggs in a glass bowl or airtight container that fits the eggs snuggly. 

Pour the marinade over the peeled eggs. If you don’t have enough marinade to almost cover the eggs, mix in a splash of water. Or turn the eggs a few times with a clean spoon during the marinade process for even coverage.

Cover the container with a lid or plastic wrap and let the eggs marinate at room temperature for at least one hour, or preferably, refrigerate overnight

Step 4: Serve and enjoy

Remove the eggs from the marinade and refrigerate them in a clean airtight container. You can safely keep the eggs in the marinade, but they will become rubbery and overly salty.

They will keep in the fridge for up to four days

Serve the mayak eggs as a side dish with cooked rice and Korean banchan like Korean cucumber salad, spicy scallion salad, and sesame broccoli banchan.

How to serve mayak eggs

Mayak eggs are a classic Korean side dish that is incredibly versatile. Serve them as a snack, for breakfast, in a bowl of hot ramen, or as part of a bigger Korean meal. 

Breakfast: For a traditional Korean breakfast, serve these eggs with rice, kimchi, and a drizzle of toasted sesame oil. Or quarter the Korean boiled egg and arrange the segments on a slice of buttered sourdough for an easy indulgent breakfast. I also love to wrap quartered mayak eggs in a nori sheet with kimchi for a quick breakfast (but I’m weird like that).

Noodle bowl: Slice the eggs in half and serve them in a bowl of noodle soup. Or pop them into brothy instant ramen for a quick dinner fix. They are also delicious with spicy Korean noodles (noodles with gochujang sauce). Noodle soup is also delicious topped with crispy green onion salad.

Rice bowl: Top a bowl of steamed white rice with mayak eggs and serve with more Korean side dishes (banchan). Try a spicy Korean cucumber salad, broccoli sesame salad, gamja jorim (soy-braised potatoes), and some kimchi. Top with shredded gim (Korean roasted seaweed) or nori. Or add mayak eggs to Korean fried rice with gochujang and kimchi.

Salad: Slice the eggs into wedges to top a crunchy green salad. Add a sprinkle of toasted sesame seeds and a drizzle of leftover egg marinade vinaigrette.

These marinated eggs are a great way to bulk up any meal with an added umami flavour punch.

What about the leftover egg marinade?

Because the sauce contains fresh ingredients, it is best to refrigerate the leftover sauce and use it within four days. 

But if you strain out the fresh aromatics (garlic, green onion, and chilli pepper), the sauce will stay fresh longer. Keep the strained sauce for up to two weeks, but allow it to simmer for a few minutes before use to kill off potential bacteria introduced by the fresh ingredients.

So, you can use the leftover sauce uncooked for the first four days (in salad dressing, poke bowls or rice bowls). But beyond four days, you should simmer the strained sauce before use.

You can also freeze the marinade in an ice cube tray for instant pops of flavour.

If you omit all of the fresh aromatics and use a simple soy-based marinade of soy sauce, honey and vinegar, you can reuse the marinade for your next batch of eggs. 

But I love the flavour of the fresh aromatics. And there are more than enough ways to use up the leftover soy marinade:

  • Use your fresh leftover marinade as a stir-fry sauce for proteins, veggies, noodles and egg-fried rice. 
  • Add it to braised meats or tofu – mix three tablespoons leftover marinade with two tablespoons gochujang paste and use it for Gochujang tofu (spicy Korean braised tofu)
  • Mix it with grated ginger and rice vinegar to turn it into an Asian-style salad dressing (while the sauce is still fresh). 
  • Or use it as a dipping sauce for dumplings, spring rolls, tempura or even sushi.

      Yes, remove the eggs from the marinade and refrigerate them in a clean airtight container. If you keep the eggs in the marinade, they will become rubbery and overly salty.
