You can tell when eggs are done boiling by using a combination of timing, physical tests, and visual cues:
Timing Guidelines for Boiled Eggs
- For soft-boiled eggs with runny yolks, boil for about 6 to 7 minutes.
- For hard-boiled eggs with fully cooked yolks, boil for 12 to 14 minutes.
- Some sources suggest 10 minutes for classic hard-boiled eggs, but 12-14 minutes ensures fully set yolks
Physical Tests to Check Doneness
- Spin Test: Place the egg on a flat surface and spin it. A hard-boiled egg spins quickly and smoothly, while a raw egg wobbles and spins slowly due to the liquid inside. When you stop the spinning egg with your finger, a hard-boiled egg stops immediately, but a raw egg will continue to wobble
- Float Test: Contrary to some beliefs, hard-boiled eggs do not float in water. This test is not reliable for doneness
Visual and Temperature Indicators
- You can shine a flashlight through the egg to see differences in opacity; cooked eggs appear more solid inside
- The internal temperature of a hard-boiled egg should reach at least 160°F (71°C) to be fully cooked and safe to eat
- After boiling, immediately cool eggs in ice water to stop cooking and make peeling easier
Summary of How to Know Eggs Are Done Boiling
- Use a timer set according to desired doneness (6-7 min for soft, 12-14 min for hard).
- Perform the spin test: a hard-boiled egg spins easily and stops quickly when tapped.
- Optionally, check internal temperature (≥160°F) for food safety.
- Cool eggs quickly in cold water after boiling.
These methods combined give a reliable way to know when your eggs are done boiling without cracking them open prematurely.
