How Long to Boil Eggs (Soft, Medium and Hard)

Boiling eggs is timed, not temped. Unlike a steak or a chicken breast, you are not going to slide a thermometer into a small egg mid-cook, so you rely on the clock and the visual result: a jammy soft yolk, a barely-set medium, or a firm hard-cooked center. The times below are the doneness preference part of the equation, and they are what most people mean by soft, medium, and hard boiled.

Food safety is the other half. The USDA safe minimum internal temperature for eggs and egg dishes is 160°F (71°C). A hard-boiled egg sails well past that, which is why it is the safe choice for higher-risk eaters. Soft- and medium-boiled eggs keep a loose or runny yolk that never reaches 160°F (71°C), so treat them as a doneness preference for healthy adults, not a guaranteed-safe cook. When a recipe or diner needs the safety guarantee, a food thermometer in a cooked egg dish (like a casserole or quiche) is the only way to confirm 160°F (71°C).

How to use these times

Start the clock the moment the water reaches a rolling boil, not when the eggs go in. The times in the table assume you are lowering eggs into already-boiling water; if you start eggs in cold water, see the note below. Use a timer, keep the water at a gentle boil rather than a violent one, and have an ice bath ready before you start. Because eggs are too small to probe reliably, the timer is your main tool for texture, while a food thermometer is reserved for cooked egg dishes where you can measure the center.

Cold-water start: Instead of dropping eggs into boiling water, place them in a single layer, cover with cold water by about an inch, and bring to a boil. Once it reaches a rolling boil, remove from heat, cover, and let stand about 9 minutes for soft, 12 for medium, and 15 or so for firm hard-cooked. This gentler ramp reduces cracking but is harder to time precisely, so it favors hard-cooked results.

Tips for better boiled eggs

• Ice bath: The moment the timer ends, transfer eggs to a bowl of ice water. This halts cooking so a 6-minute yolk stays runny, and it makes the shells far easier to peel.
• Egg size matters: These times are for large eggs. Add roughly 1 minute for extra-large or jumbo, and shave about 1 minute for medium eggs.
• Altitude matters: At high elevation, water boils below 212°F (100°C), so eggs cook slower. Above about 3,000 feet, add 1 to 2 minutes and lean toward the longer end of each range.
• Peel easier: Slightly older eggs peel more cleanly than very fresh ones, and cracking the shell before the ice bath lets water slip under the membrane.
• Confirm safety by temp, not time: For egg casseroles, quiche, or any baked egg dish, use a food thermometer and cook to 160°F (71°C) rather than guessing by minutes.
• Don't leave them out: Refrigerate hard-boiled eggs within 2 hours and use within 1 week.

Are soft-boiled eggs safe to eat?

For healthy adults, a soft-boiled egg is a common doneness preference, but its runny yolk never reaches the USDA safe minimum of 160°F (71°C). It is not guaranteed pathogen-free. Anyone in a vulnerable group should skip runny yolks and eat firm-cooked eggs instead.

What temperature is a safely cooked egg?

The USDA safe minimum internal temperature for eggs and egg dishes is 160°F (71°C), checked with a food thermometer. This is the safe minimum, separate from how firm you personally like the yolk. Fully hard-boiled eggs are well past 160°F (71°C).

Who should only eat firm, hard-cooked eggs?

Vulnerable groups, including young children, older adults, pregnant people, and anyone with a weakened immune system, should eat eggs cooked until both the white and yolk are firm, or in dishes cooked to 160°F (71°C). Runny soft- and medium-boiled yolks are not recommended for them.

Should I start eggs in cold or boiling water?

Boiling-water starts give you precise, repeatable timing, which is best for soft and medium eggs. Cold-water starts ramp up more gently and reduce cracking, but they are harder to time exactly, so they suit firm hard-cooked eggs. Either way, the ice bath at the end is what stops the cooking.

Why won't my eggs peel cleanly?

Very fresh eggs cling to their shells. Use eggs that are a few days to a week old, shock them in an ice bath right after cooking, and peel under running water. A quick crack-and-roll before peeling helps the shell release.
