Known as Ajitsuke Tamago or Ajitama in Japanese, Ramen Eggs are delicious as a topping on ramen or enjoyed as a snack. Learn to make these flavorful, perfect soft-boiled eggs with just five ingredients!
A great bowl of ramen is built upon a few significant components. There’s hot broth, fresh-made noodles, and the toppings. As far as the toppings go, no one can resist a perfectly cooked ramen egg that sits alongside sliced chashu, a sheet of nori, and green onions. Some would even argue that ramen egg is a must!
When done right, ramen egg is creamy, silky, full of umami, and ready to enrich and intensify your ramen enjoyment. The truth is, ramen eggs are not just for ramen alone. You can enjoy these delicious eggs anytime, in many different ways!

What Are Ramen Eggs?
Ramen eggs are Japanese soft-boiled eggs known for their custardy, jammy, runny yolk, and umami flavor. They are marinated overnight in a sweetened soy-based sauce. In Japan, we call these marinated eggs Ajitsuke Tamago (味付け玉子), short for Ajitama (味玉) or Nitamago (煮玉子).
While these eggs are excellent on ramen, they are also fantastic to enjoy as a side dish, snack, or packed in a bento. Don’t limit yourself there! You can even add them to salads or sandwiches. That’s the magic of ramen eggs. They are so good and amazingly versatile.
Ingredients for Ajitsuke Tamago
Five ingredients are all you need, and you’ll be surprised at how easy it is to make ramen eggs at home.
- Good quality eggs, especially if you plan to make soft-boiled eggs
- Soy sauce
- Mirin
- Sake (or water)
- Sugar
For the marinade, you can create your version with additions (such as chili flakes for spice, etc), but let’s stick with the basics.
What changed from the 2011 Recipe?
Some of you might be familiar with the original recipe I shared in 2011. In the past, I used water instead of sake. However, for food safety reasons, I started making my ramen eggs with sake and like this version much better.
Why sake? The amino acids in the fermented rice wine enhance food flavors by adding hints of sweetness and umami, which makes the eggs taste better. In case you’re wondering, we would boil off the alcohol from the sake before marinating the eggs so it’s perfectly safe for kids to consume.
As part of the refinement, I also added a bit of sugar. To put the old and new recipes to the test, I had my family try out the two versions multiple times, and they concluded that the winner goes to this updated recipe. For those who can’t consume alcohol, you can still use water.

Cooking Tips
Tip #1: Cook the marinade
To make the marinade, I highly recommend cooking it for 1 minute after boiling. This ensures the sugar dissolves and the alcohol evaporates, leaving only the natural umami and sweetness in the sauce.
Tip #2: Use refrigerated eggs
Using a fine-mesh sieve/strainer, gently lower your eggs straight from the fridge into the (already) boiling water and lower the heat slightly to a simmer.
Tip #3: Cook 7 minutes from the first egg in boiling water
Start setting the timer for 7 minutes from the first egg submerged in boiling water. It takes about 30 seconds or less to submerge all four eggs (set the timer for 6 minutes and 30 seconds if you start the timer when you finish submerging all the eggs. Little adjustment matters!)
I use large American eggs for this recipe, and knowing that egg sizes vary in different parts of the world, you might need to adjust the cooking time slightly.
Tip #4: Shock the eggs in ice water
Shock the boiled eggs in ice water immediately and let them chill for at least 15 minutes. I use the same ice water to dip the boiled eggs a few times when peeling them. Water goes into the gap and helps peel easily.
Tip #5: Marinate the eggs overnight
Marinate the ramen eggs for just a few hours or overnight. I can make ramen the next day while the eggs stay marinated in the fridge, waiting for their appearance.
How To Store Ramen Eggs
Soft-boiled eggs should be consumed in 3-4 days. Keep the Ajitsuke Tamago or ramen eggs in the refrigerator at all times. Use a clean utensil to take out a marinated egg, if you continue to marinate the rest of the eggs. I’d take out the ramen eggs after soaking them overnight as I don’t want my eggs to be too salty. You can marinate for up to 2 days at most, but I recommend removing from the marinade after that.
How To Serve Ramen Eggs
I hope you’ll try this recipe because it can make your day better. Here are my absolute favorite ways to enjoy the eggs.
- Serve with Miso Ramen
- Serve with Vegetarian Ramen
- Serve with Tsukemen (Dipping Ramen Noodles)
- Serve on Avocado Toast
- Serve with Japanese Curry
- Pack in Bento Box

Ramen Eggs (Ajitsuke Tamago)
Video
Ingredients
- 4 large eggs (50 g each w/o shell) (refrigerated; use slightly older eggs, which are easier to peel)
Instructions
- Before You Start: Please note that this recipe requires a marination time of 8 hours or overnight. Gather all the ingredients.
To Make the Marinade
- In a small saucepan, combine all the ingredients for the marinade: ¼ cup soy sauce, ¼ cup mirin, ¼ cup sake, and 1 tsp sugar.
- Bring it to a boil and whisk it a few times to let the sugar dissolve completely. Once boiling, lower the heat and simmer for 1 minute. Turn off the heat. Set aside to cool completely.
To Make the Soft-Boiled Eggs
- Add 4 cups (1L) water (for 4 eggs) to a medium saucepan and bring it to a boil. There should be enough water to cover the eggs by at least 1 inch (2.5 cm). Once at a full boil, take out 4 large eggs (50 g each w/o shell) from the refrigerator. Carefully and gently lower one egg at a time into the boiling water with a mesh strainer/skimmer or a ladle. When you add the first egg, set a 7-minute timer. You can cook them 6 to 6½ minutes for a runny egg yolk and 8 to 9 minutes for a custard-like egg yolk.
- Once all the eggs are in the saucepan, lower the heat to maintain a gentle boil. Make sure the water is simmering, but not bubbling so strong that the eggs bounce around. If you want your egg yolks to be centered, gently rotate the eggs with chopsticks once in a while for the first 3 minutes.
- After 7 minutes, immediately take out the eggs and shock them in iced water for 15 minutes.
- Once the eggs are completely cool, gently crack the shell at the wide bottom end of the egg and start peeling it vertically toward the pointy top. Dip the egg in the iced water a few times to help with the peeling. Once you peel one section vertically, the rest of the shell comes off easily.
To Marinate the Eggs
- Place the eggs in a plastic bag and add the marinade to the bag. Why am I recommending a plastic bag? With a plastic bag, we don‘t have to use a lot of marinade to submerge the eggs. This marinade is used only one time for food safety reasons, so it’s most economical to prepare no more than the amount you need. If you use a container instead of a bag, it requires more marinade to submerge the eggs.
- Remove the air from the bag and use a clip or rubber band to seal the bag right above the eggs. This way, the eggs are completely submerged in the marinade. Refrigerate for 8 hours or overnight. You can rotate the eggs occasionally if you like.
To Serve
- Remove the eggs from the marinade and cut them in half lengthwise to serve. Use a piece of string, fishing line, or cheese cutter (that‘s what I used here) to cut the eggs in half cleanly. Enjoy the Ramen Eggs in bento, as a ramen topping, or as a snack sliced in half and sprinkled with furikake (rice seasonings) and shichimi togarashi (Japanese seven spice). If you want to warm up the eggs, soak the bag in warm water to bring up the temperature faster.
To Store
- Keep the Ramen Eggs refrigerated at all times. Do not freeze as the texture of eggs changes when frozen (with the exception of tamagoyaki). The ramen eggs will get saltier the longer they marinate, so take them out from the marinade after 12–24 hours (depending on your preference). Enjoy the ramen eggs within 3–4 days if your eggs are soft-boiled. If your eggs are hard-boiled, you can keep them in the refrigerator for up to a week. For food safety reasons, I do not recommend reusing this marinade with new boiled eggs. You can repurpose this marinade as a seasoning sauce for your stir-fried or simmered dishes but use it soon.

I always wondered how restaurants made their ramen eggs. These eggs were just as good! Thank you so much for sharing this recipe. My family and I loved it with our ramen.
Hi Stephanie! Thank you for trying this recipe and I’m so happy to hear you enjoyed it with your ramen. Thank you for your kind feedback! 🙂
Although I didnt top my ramen with this egg recipe, I did top my Japanese Curry with it! It was soft, creamy and just delicious! Thank you for this amazing recipe!!
Hi Emily! We use these eggs for non-ramen dishes too! I’m glad you enjoyed this recipe and thank you for your kind feedback! 🙂
Thanks for sharing this recipe. My eggs turned out amazing! I can’t wait to make them again.
Thank you so much for your kind feedback, Monica! I’m so glad to hear you enjoyed them. 🙂
I really love your ramen egg recipe (using it with your miring substitute recipe) and also get a positive feedback about their taste 🙂 So thank you very much for sharing 🙂
Hi Pascal! I’m so happy to hear that. Thank you for writing your kind feedback. 🙂
I find that steaming the eggs gives more consistent results. It also makes peeling them a breeze. For soft “boiled” I steam them for 6 1/2 minutes. 7 mins if I want a more custard like consistency.
Hi Mike! Thank you for sharing your tip! 🙂
This is such a helpful recipe! I know from experience from making Chinese Tea Eggs that your method is THE best way to get the shell off cleanly when you crack it! I’ve tried so many ways of boiling eggs, but the absolute best way is to start the eggs in the hot water (not put them in the water before it is boiling) and to put them into an ice water bath immediately when done. If the eggs are cold from the fridge at first, this sudden temperature change can sometimes cause one or two to crack when put into the water, but it doesn’t usually leak out much of the egg and still cooks just fine. I would estimate it would take a minute or two off the cooking time if starting with room temp eggs.
I am really excited to make these! It will be a breeze since these are quite like tea eggs but much simpler! No having to simmer all the tea and spices in the sauce! Just good ol’ soy sauce and mirin. <3
And now for my shameful confession, I will be using these in instant ramen. 😛 I'd love to make ramen homemade someday, but there are many other recipes on your site I'd love to try first! For now, this will be my add-on when I need a quick late-night instant ramen fix! Thanks for sharing!
Thank you for your kind feedback, Lion! I’m so happy you liked the recipe. 🙂 Instant ramen is good, as long as you don’t eat it everyday. 😉 Enjoy!
Hi, love your blog. Just a quick question I can’t use alcohol, is there anything that can substitute the mirin or should I just omit it? Thanks!
And I accidentally replied to someone else. That’s what I get for using my phone ????
Hi Nem! The only substitution besides alcohol is water. It doesn’t have same cooking effect but you will need the same amount of liquid to go in, so that the seasonings are “diluted”. 🙂
Hello I have no real access to mirin is there an adequate substitute?
Hi Michele! I’m so sorry for my late response. Mirin is basically sake + sugar. So if you can find Chinese cooking wine or dry sherry and add sugar, that’s a good substitution.
1 Tbsp mirin = 1 Tbsp sake/water + 1 tsp sugar.
Thanks so much for this recipe – I LOVE the eggs I get at ramen shops! How long can you leave the eggs in the marinade? I’m thinking of making a whole batch of 10 eggs and having 2 per day (instead of having to boil and peel eggs every day)?
Hi Sarah! Overnight is pretty good. I think 5 days is kind of too long for the eggs to be sitting in the marinade. Maybe 3-4 days at most? 🙂
My refrigiratwd eggs cracked as soon as they touched the water.
Hi Kevin! Did you gently submerge them using a ladle or strainer? I do this all the time, but the eggs never broke because of the hot water. I wonder what else could cause them break…. Sorry I wish I know.
I’m going to try this soon. I have a few eggs I need to use up soon, as well as a busy weekend ahead.
When I was in college years ago, I used to tutor a girl whose mother is Japanese. As a part of my payment, she would make me ramen with an egg on top. I never learned how she made them, so thanks for the recipe.
Hi Ren! Hope you enjoy this recipe and it’s close to what you tasted back then. 🙂
Today was Ramen Soup day in our household, so I found the recipe for your eggs and gave them a try. My girls loved them so much that they asked me to JUST fix them a bowl of these eggs! I usually put one whole sliced egg per bowl, but now I will probably have to double or triple that request to appease my crew. I guess I should just rename it Ramen Egg Soup day. Thanks for a great recipe!
Hi Annie! I’m so happy to hear you and your children love this recipe! Thank you so much for trying this recipe! 🙂
Thanks for the recipe, these eggs look and sound perfect and I can’t wait to make them. However, I’m cooking at high altitude (7,000 feet). How much longer should I boil the eggs in this case? Thanks!
Hi Sean! I wish I could tell, but I’ve never cooked in high altitude so I don’t know…. Sorry! You might need to test and see. You just need to test once (then next time you’ll know). Write number on each egg and test the egg every minute around 7 mins to see what’s your liking based on high altitude cooking.
If anyone who reads this comment and knows the answer, please share your tip! 🙂
Thanks for your response! I will get to testing them out and see what I get.
Good luck! 😀
Just made these and placed the eggs to marinade so haven’t had the final product yet, but wow! Just snacked on one (made several) and the inside was just the perfect custardy consistency described at 7 minutes. Not always the case for recipes found via pinterest. Can’t wait to have the end result!
Hi Maria! I hope the final product was good! Thanks for trying this recipe! I’m happy to hear you came from Pinterest. Welcome! 🙂
I love these eggs. Infact I made them for breakfast this morning with toast and coffee. Made four, couldn’t let my husband starve. Thanks Nami for such great recipes, you are an amazing lady. 🙂
Hi Jacquie! What a great breakfast with toast and coffee! I’m so happy you enjoyed this dish. Thank you for your feedback!
