Learn how to make silky Japanese hot spring eggs (onsen tamago) with custard-like whites and jammy yolks in just 10 minutes. This simple, foolproof method requires only eggs and water for a luxurious breakfast or topping.

Ingredients

Scale
  • 46 fresh large eggs, at room temperature
  • Water (enough to cover eggs by at least 1 inch)
  • Ice bath (water and ice cubes)
  • Optional: Soy sauce, sesame oil, furikake, or flaky salt for serving

Instructions

  1. Bring your eggs to room temperature by taking them out of the fridge about 15 minutes before cooking. If in a rush, place them in a bowl of warm tap water for 5 minutes.
  2. Fill a medium saucepan with enough water to cover the eggs by at least an inch. Place over medium-high heat.
  3. Heat the water to exactly 167°F (75°C). Use a thermometer to monitor. Once it reaches 167°F, reduce heat to low to maintain that temperature.
  4. Gently lower the eggs into the water using a slotted spoon. Do not drop them in to avoid cracking.
  5. Set a timer for 10 minutes. Do not stir; let the eggs sit in the 167°F water with the heat on low.
  6. While the eggs cook, prepare an ice bath by filling a bowl with cold water and a generous handful of ice cubes.
  7. After exactly 10 minutes, use the slotted spoon to transfer the eggs to the ice bath. Let them sit for 2-3 minutes to stop the cooking process.
  8. To serve, gently tap the egg around the middle and crack it directly over a bowl of rice, salad, or ramen. The white will be soft and the yolk runny. Alternatively, cut off the top of the shell and eat with a spoon.

Notes

Temperature is critical: maintain a steady 167°F (75°C). Do not crowd the pot; cook no more than 4 eggs at a time. For best results, use room temperature eggs. If peeling, crack directly over the dish rather than peeling like a hard-boiled egg. Leftover eggs can be stored in the shell in the refrigerator for up to 2 days; reheat in warm water (not microwave).
