Ajitama Recipe (Ajitsuke Tamago / Ramen Eggs)

Ajitama, also known as ajitsuke tamago or Japanese ramen eggs, are soft-boiled eggs marinated in a savory-sweet soy sauce mixture with a creamy, jammy yolk. This easy recipe shows you how to make them perfectly at home.

Ajitama, also known as ajitsuke tamago or Japanese ramen eggs, have become just as famous as the ramen bowls they’re served with. With their creamy, jammy yolk and savory soy-based marinade, these flavorful eggs are one of the most beloved toppings in Japanese recipes.

The yolk is rich and jelly-like while the egg white stays tender and slightly chewy—an irresistible combination. While ajitama is perfect on ramen, they’re also delicious on rice bowls, noodle dishes, or alongside other Asian egg recipes like egg fried rice or tomato egg stir fry.

Recipe Ingredients

Ingredient Notes

Soy Sauce – Use a regular Japanese soy sauce like Kikkoman for the best flavor. If you’re gluten-free, you can substitute with tamari. A darker soy sauce will give your ajitama eggs a deeper brown color while keeping the flavor balanced and not overly salty.

Mirin – Mirin is a sweet Japanese rice wine that adds a subtle sweetness and depth of flavor to the marinade. It’s essential for authentic ajitsuke tamago and pairs beautifully with soy sauce. Keep a bottle in your fridge—it’s useful for many Japanese recipes.

Sake (Japanese Rice Wine) – Sake helps balance the sweetness of mirin and the saltiness of soy sauce, creating a well-rounded marinade. If you don’t have sake, you can substitute with dry white wine, though the flavor will be slightly different.

Whole Spices (Optional) – Star anise, cloves, and bay leaves add a subtle aromatic depth to the marinade. These are optional but can enhance the overall flavor of your ramen eggs. Since they’re dried, you can store them for a long time in your pantry.

Water or Chicken Stock – Use water for a cleaner taste, or chicken stock for a richer, more savory marinade. Both work well depending on your preference.

Substitutions & Variations

Different types of eggs – You can use chicken eggs, duck eggs, or quail eggs for this ajitama (ajitsuke tamago) recipe. Adjust the marinating time based on size—quail eggs may only need about 10–12 hours, while larger eggs benefit from a longer soak.

Flavor variations – For a deeper flavor, you can add aromatics like ginger or garlic to the marinade. If you prefer a bit of heat, a pinch of chili flakes or cayenne pepper works well with the savory soy-based sauce.

Alcohol-free option – If you prefer not to use alcohol, choose a non-alcoholic mirin. You can also substitute mirin with a mix of dry white wine and a little sugar to mimic its sweetness and balance.

How to Make Ajitama (Ajitsuke Tamago)

STEP 1. In a pot, combine water, soy sauce, mirin, sake, star anise, cloves, and bay leaves (Image 1). Bring the mixture to a gentle simmer over low heat and let it cook for about 5 minutes to allow the alcohol to evaporate (Images 2, 3). Turn off the heat and let the marinade cool completely.

Meanwhile, bring a separate pot of water to a boil (Image 4). Gently add the eggs and cook for 6 minutes 30 seconds for perfectly jammy yolks.

STEP 2. Transfer the cooked eggs into an ice bath to stop the cooking process (Image 5). Let them cool completely—this helps make peeling easier and keeps the surface smooth. Peel the eggs carefully, then place them into a zip-top bag (Image 6). Pour the cooled marinade over the eggs, making sure they are fully submerged (Image 7). Seal the bag and refrigerate (Image 8) for at least 24 hours (up to 48 hours for deeper flavor).

STEP 3. Remove the eggs from the marinade and slice them in half (Images 9, 10). You’ll see the beautiful jammy yolk and deep brown exterior (Image 11).

Serve your ajitama eggs with ramen, rice bowls, or enjoy them on their own.
