Breakfast & Brunch
This 65-degree egg recipe delivers the perfect balance of silky yolk and tender whites—Japanese-style eggs cooked to 149°F for a luxurious, custardy center. The secret lies in precise temperature control and a flavorful marinade that transforms ordinary eggs into a restaurant-worthy dish.
I've perfected this technique after years of experimentation, ensuring every bite is rich, creamy, and packed with umami.
The process begins with a simple yet essential marinade of soy sauce, mirin, sugar, and vinegar, which infuses the eggs with depth and balance. Once marinated, the eggs are gently cooked to achieve that signature 65°C internal temperature—whether through simmering in broth, steaming, or sous-vide.
The result? A silky, runny yolk that clings to the egg whites, creating a texture that’s both indulgent and satisfying.
What makes this dish truly special is its versatility. Serve these eggs over steamed rice with a side of miso soup, or pair them with a drizzle of ponzu for a burst of citrus brightness.
The custardy yolk also makes them perfect for dipping into soy sauce or sprinkling with sesame seeds and chili oil for an extra kick.
For food safety, it’s important to note that these eggs are cooked to a precise temperature, but those who are immunocompromised or pregnant should avoid consuming them. With this recipe, you’ll master the art of achieving that perfectly silky yolk every time—transforming a simple breakfast into an unforgettable experience.
Ingredients for 65 degree egg
Japanese precision meets restaurant-quality umami in these 12 essential ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 4 whole | Room temperature for even cooking |
| Japanese Soy Sauce 🥫 | ¼ cup | Kikkoman preferred for balance |
| Mirin 🍶 | ⅛ cup | Sweet rice wine, not cooking wine |
| White Sugar 🍚 | ⅛ cup | Granulated, fine grain preferred |
| Rice Vinegar 🍶 | 1 tbsp | Seasoned or unseasoned both work |
| Dashi Broth 🍵 | 2 cups | Homemade or premium instant |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty for proper sealing |
| Sesame Seeds 🌾 | 1 tbsp | Toasted for garnish |
| Chili Oil 🌶️ | 1 tbsp | Optional, for serving |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | For seasoning broth |
| White Pepper 🌶️ | ¼ tsp | Freshly ground for subtle heat |
| Ponzu Sauce 🍋 | ¼ cup | For serving, optional |
The eggs are the foundation, so choose fresh, high-quality eggs—room temperature is critical for even cooking. Kikkoman soy sauce delivers the perfect balance of salt and depth, while mirin adds that signature sweetness without overpowering. For dashi broth, homemade wins (bonito flakes and kombu), but premium instant like Hontou works in a pinch. The rice vinegar should be seasoned for complexity, though unseasoned adds brightness. Toast your sesame seeds in a dry pan for 30 seconds—they’ll release their nutty aroma instantly. If you're using ponzu sauce, Kikkoman or Wright's are the gold standards, but any citrusy soy-based sauce will work.
No mirin? Substitute 1 tbsp sugar plus 1 tbsp dry sherry—the alcohol burns off during cooking. Running short on dashi? Vegetable broth with a dash of soy sauce gets you close, though it’ll lack that unmistakable umami depth. For the foil sealing, heavy-duty foil is non-negotiable—standard foil won’t hold the heat. If you can’t find Japanese soy sauce, regular soy sauce with an extra pinch of sugar mimics the flavor profile. The chili oil is optional but adds that perfect finishing touch—Lao Gan Ma or homemade are my go-tos. For a vegetarian dashi, shiitake mushrooms and kombu create a rich alternative.
Marinated eggs keep in the fridge for 2 days maximum—the texture degrades after that. Cooked eggs in foil cups reheat beautifully in a 200°F oven for 10 minutes, though they’re best served fresh. Store dashi broth in the fridge for 5 days or freeze for 3 months. For the marinade, combine all ingredients in a bowl and let sit at room temperature for 30 minutes before adding eggs—this ensures even flavor infusion. The foil cups can be prepped ahead and frozen for 1 month, then cooked straight from frozen by adding 5 minutes to the simmering time.

Step-by-step instructions for 65 degree eggs
Precision is everything when creating these delicate, silky yolks—follow these exact steps.
Prepare the Flavor Base
In a small saucepan, combine the 2 cups dashi broth, 0.25 cup Japanese soy sauce, 0.125 cup mirin, 0.125 cup white sugar, and 1 tbsp rice vinegar. Bring to a gentle simmer over medium heat until the sugar fully dissolves and the mixture reduces slightly—about 3-4 minutes. The liquid should smell aromatic with a balance of umami and sweetness.
Remove from heat and stir in the 0.5 tsp Diamond Crystal kosher salt and 0.25 tsp white pepper. Let the mixture cool to room temperature before proceeding—this ensures even heat distribution when we seal the eggs. The broth should be smooth and free of any graininess, indicating proper reduction.
Create Foil Cups for Precision Cooking
Cut the 1 sheet aluminum foil into four 4-inch square pieces. Fold each square in half to create a crease, then fold in half again to form a small pocket. Place one folded piece in each of four ramekins or small heatproof dishes—these will act as our temperature-controlled chambers.
Crack one whole large egg into each foil pocket, ensuring the yolk and white are centered. Pour ¼ cup of the cooled broth mixture into each pocket, completely submerging the egg. The broth should cover the egg by about ½ inch—this ensures even heat transfer and prevents the white from overcooking.
Seal and Submerge for Perfect Texture
Carefully fold the foil edges upward to create a sealed cup around each egg. Press the edges firmly to eliminate any air pockets—this prevents steam from escaping and maintains the 65°C (149°F) target temperature. Place the sealed ramekins in a deep pot and add enough water to come ¾ of the way up the sides of the ramekins.
Bring the water to a gentle simmer over low heat, ensuring the water temperature remains below 90°C (194°F). The water should barely move—you're not boiling, just maintaining a steady temperature. This indirect heat method is critical for achieving the signature silky yolk without cooking the white.
Monitor and Rest for Optimal Doneness
Cook for exactly 12 minutes from when the water first reaches a simmer. The foil will create a steam environment that cooks the eggs to 65°C (149°F) at their center—hot enough to set the yolk into a luxurious custard texture while keeping the white perfectly translucent. Use a thermometer to verify the water stays between 85-90°C (185-194°F) throughout.
Remove the ramekins from the water and let them rest for 5 minutes before opening. This resting period allows the heat to distribute evenly within the eggs, preventing any potential overcooking when you finally open the foil. The yolk should still appear slightly wobbly at the edges—this is your confirmation of perfect doneness.
Carefully open each foil packet and transfer the eggs to serving plates. Drizzle with the Serve with Garnishes and Sauces
Serve immediately while the eggs are still warm. Each bite should deliver a perfect balance of silky yolk and delicate white, with the broth-infused flavors enhancing rather than overpowering the egg's natural taste. The texture should be firm yet tender—like a cloud with a custard center.
Pro Tips For Making 65 Degree Egg
- Chill the Eggs First: Pop those eggs into ice water for 10 minutes before poaching—cold eggs slide into the simmering liquid cleaner and hold their shape better. I learned this the hard way when my first batch turned into a jiggly mess from room-temperature eggs.
- Simmer, Don’t Boil: Keep the water at a gentle simmer—tiny bubbles breaking the surface, not rolling like a pot of pasta. Too hot and your whites turn rubbery; too cool and they stay undercooked. A thermometer helps, but even without one, watch for a steady, quiet ripple.
- Whisk the Soy Sauce: Don’t just dump that soy sauce in—whisk it with the mirin and sugar first until it’s fully dissolved. I used to skip this, and my sauce would clump in the egg’s center, leaving a weird, grainy texture. Takes 30 seconds, saves you from weird mouthfeel.
- Vinegar Last, Not First: Add rice vinegar after the eggs are poached and draining—it’s what tightens the whites and gives that glossy finish. If you toss it in the poaching water too early, the acid can make the whites break apart when you try to lift them out. (Yes, I’ve done this.)
Best sauces and condiments for 65 degree egg
Classic Soy-Ginger Sauce
This is my go-to sauce for 65-degree eggs—simple yet packed with umami depth. Whisk together ¼ cup Japanese soy sauce, 1 tbsp mirin, 1 tbsp rice vinegar, 1 tsp grated fresh ginger, and ½ tsp white pepper.
Let it sit for 10 minutes to meld flavors before drizzling over the eggs. The ginger adds warmth that perfectly complements the silky yolk. 💛
Spicy Chili Sesame Drizzle
For heat lovers, blend 1 tbsp toasted sesame oil, 1 tsp chili crisp, ½ tsp sugar, and ¼ tsp garlic powder until smooth. Drizzle lightly over the eggs just before serving—the chili crisp adds smoky heat while the sesame oil enhances the egg's natural richness.
This sauce is especially good with the custardy yolk. 🌶️
Citrusy Ponzu Variation
Use ¼ cup ponzu sauce (like Kikkoman) mixed with 1 tsp honey and a pinch of salt for a bright, tangy contrast. The citrus notes cut through the egg's richness while adding a refreshing finish.
I like to serve this with a sprinkle of toasted nori strips for extra texture. 🍋
Miso-Butter Glaze
For a richer option, mix 2 tbsp white miso paste with 1 tbsp softened butter and 1 tsp honey. Warm gently until smooth, then drizzle over the eggs. The miso adds fermented depth while the butter creates a luxurious coating. This works beautifully with the delicate whites. 🧈
Sweet-Savory Shoyu Glaze
Reduce ¼ cup soy sauce with 1 tbsp mirin and 1 tsp sugar until syrupy (about 3 minutes). The concentrated flavors cling perfectly to the eggs' surface, enhancing their natural taste without overpowering. This glaze is especially elegant for special occasions. 💫

Frequently asked questions
Why is 65°C (149°F) the perfect temperature for these eggs?
This precise temperature transforms the yolk into a luxurious custard while keeping the whites tender. At 65°C, the proteins coagulate just enough to create that signature silky texture—hot enough to be safe but cool enough to remain creamy. Any higher, and the yolk becomes rubbery; too low, and it stays runny like a raw egg.
Can I use regular soy sauce instead of Japanese soy sauce?
You can, but the flavor will be slightly saltier and less complex. Japanese soy sauce has a smoother, sweeter profile that balances perfectly with mirin and sugar. For a quick fix, use regular soy sauce plus an extra ½ teaspoon of sugar per ¼ cup to mimic the flavor. The texture won't change, just the depth of umami.
What if I don't have aluminum foil cups? Can I use ramekins or egg cups?
Yes! Foil creates a steam environment, but ramekins or small heatproof dishes work too—just ensure they're oven-safe and can be submerged in water. For best results, preheat them in the broth for 2 minutes before adding eggs to equalize temperatures. The key is maintaining that gentle simmer below 90°C (194°F).
How do I know when the eggs are perfectly cooked?
The yolk should be slightly wobbly at the edges when you gently shake the ramekin—like a soft custard. If it moves freely, it's undercooked; if it holds its shape, it's overdone. For precision, use an instant-read thermometer to check the water stays between 85-90°C (185-194°F) during cooking. The 5-minute rest after cooking is critical for even texture.
Are these eggs safe to eat for everyone?
While cooked to 65°C (149°F), these eggs are still delicate. Those with weakened immune systems, pregnant women, or young children should avoid them due to potential salmonella risks. For extra safety, add 1 tsp vinegar to the marinade (it helps kill bacteria) or serve with a side of hot miso soup to raise the internal temperature further. Always use fresh, high-quality eggs.
