How long to boil eggs: times for every level of doneness
Simple cooking times for runny, jammy and fully firm eggs, plus practical guidance for cooling, peeling and safe storage.
Egg boiling time chart
These times begin after the eggs are lowered into gently boiling water. They are a practical starting point for large eggs taken from the refrigerator. Keep the water at a controlled boil rather than a violent one, which can knock eggs together and crack the shells.
The exact center will vary with the stove, pan, water volume and egg size. If you want a very specific texture, cook one test egg and adjust the next attempt in 30-second increments.
- 6 minutes: set white with a distinctly runny yolk
- 7 minutes: thick but still flowing yolk
- 8 to 9 minutes: jammy or slightly soft center
- 10 minutes: mostly firm yolk
- 11 to 12 minutes: fully firm yolk
A reliable step-by-step method
Fill a saucepan with enough water to cover the eggs by about 1 inch. Bring the water to a gentle boil. Using a spoon, lower each egg carefully so it does not strike the bottom, then start the timer immediately.
Adjust the heat so the water continues bubbling steadily without tossing the eggs around. When the selected time ends, use a slotted spoon to transfer the eggs to a bowl filled with cold water and plenty of ice. Leave them for at least 5 minutes; 10 minutes is convenient for a larger batch.
Why an ice bath matters
Heat stored inside an egg keeps cooking it after it leaves the pan. Ice water lowers the temperature quickly and helps preserve the doneness you chose, which is especially important for runny and jammy yolks.
Cooling also makes the eggs comfortable to handle. To peel, crack the shell gently all over, begin at the wider end where the air pocket often sits, and peel under a thin stream of water if the membrane sticks.
What changes the cooking time
Extra-large eggs usually need more time than medium eggs. A room-temperature egg may reach the desired center sooner than one straight from the refrigerator. Adding many eggs at once can also cool the water temporarily.
At higher elevations, water boils at a lower temperature, so cooking may take longer. If the center is softer than expected, increase the next cooking time gradually instead of using a more violent boil.
How to prevent a green or gray ring
The green-gray ring sometimes seen around a hard-cooked yolk usually results from overcooking or slow cooling. It does not normally mean the egg is spoiled, but the yolk may look less appealing and taste drier.
Use a timer, avoid leaving the eggs in hot water long after cooking, and place them in ice water immediately when the timer ends.
Food safety and storage
The FDA advises cooking eggs until both the white and yolk are firm to reduce foodborne-illness risk. Pregnant people, young children, older adults and people with weakened immune systems should avoid raw or undercooked eggs unless pasteurized products are used and handled safely.
Refrigerate cooked eggs within 2 hours. If the surrounding temperature is above 90°F (32°C), that limit becomes 1 hour. FoodSafety.gov and the USDA say refrigerated hard-cooked eggs should be used within one week. Freezing hard-cooked eggs is not recommended for quality.
- Store cooked eggs at 40°F (4°C) or below.
- Discard eggs left at room temperature beyond the safe limit.
- Keep the shell on until needed when practical.
- Do not eat an egg that smells unpleasant after opening.
Frequently asked questions
How long do you boil eggs for hard-boiled eggs?
As a starting point, cook large eggs for 11 to 12 minutes after lowering them into gently boiling water, then cool them in ice water.
Should eggs start in cold or boiling water?
Both methods work. Starting with boiling water gives the timer a clear starting point; lower eggs with a spoon to reduce cracking.
How long do boiled eggs last in the refrigerator?
U.S. federal food-safety guidance says refrigerated hard-cooked eggs should be used within one week.
Is a runny yolk safe?
An undercooked yolk carries more risk than a fully cooked egg. People at higher risk of foodborne illness should choose fully cooked eggs or pasteurized egg products.
