How Long to Boil Eggs — Soft, Medium and Hard (Chart)
For large eggs dropped into already-boiling water, soft-boiled with a runny center takes about 6 minutes, a jammy yolk takes 7–8 minutes, and a fully hard-boiled egg takes 10–12 minutes. Pull the eggs straight into an ice bath the moment the timer ends so they stop cooking from residual heat.
Exact timing shifts with egg size, how cold the eggs are when they go in, your altitude, and whether you start them in boiling water or cold water and bring the pot up together. None of these change the final texture dramatically, but a minute either way is the difference between a jammy yolk and a chalky one.
For food safety, the U.S. Food and Drug Administration recommends cooking eggs until both the yolk and white are firm, since a fully set egg destroys Salmonella far more reliably than a runny one. A soft- or jammy-yolk egg is a culinary choice below that firm-set standard, and it carries a higher risk that matters most for young children, older adults, pregnant people and anyone with a weakened immune system, according to FDA guidance on egg safety. When in doubt, cook to fully hard-boiled.
Boiling Time Chart by Doneness
| Doneness | Time in Boiling Water | Yolk Texture | Timer |
|---|---|---|---|
| Soft-boiled | 6 minutes | Runny center, set white | |
| Jammy / medium | 7–8 minutes | Thick, glossy, half-set | |
| Medium-hard | 9–10 minutes | Mostly set, slightly fudgy center | |
| Hard-boiled | 11–12 minutes | Fully firm, no dark ring with an immediate ice bath |
These times assume large eggs and a full rolling boil maintained the whole time, not a bare simmer that would need a minute or two longer.
Eggs sit alongside other everyday boiled foods that follow their own separate timing — boiling egg noodles and boiling corn on the cob both use very different times and cues for doneness, so don't reach for the egg chart when a recipe calls for either of those instead. The full cooking times chart covers boiling, baking, air frying, grilling and smoking side by side.
The Two Common Methods — Boiling Water Start vs. Cold Water Start
Dropping eggs into already-boiling water gives the most predictable, repeatable timing, which is why the chart above uses it. Lower the eggs in gently with a spoon to avoid cracking the shells against the pot, then start the timer the moment they go in.
The cold-water method — placing eggs in cold water, bringing the pot to a full boil, then removing from heat and covering — is gentler on the shells and less likely to crack, but the timing has to account for how long your pot takes to reach a boil. As a rough guide, once the water reaches a full boil, remove from heat, cover, and let sit 6 minutes for soft, 8–9 for jammy, and 12–14 for hard, then move straight to the ice bath.
Boiling Times by Egg Size
Extra-large and jumbo eggs need about 1 extra minute at every doneness level compared with large eggs, since more mass needs to heat through to the center. Medium and small eggs finish about 1 minute faster than large. If a carton doesn't state the size, weigh a couple of eggs — large eggs in the US run about 2 ounces (57 g) each.
Starting Temperature — Fridge-Cold vs. Room Temperature
Eggs straight from the refrigerator are the most common starting point and the times above are built around that. Room-temperature eggs — left out for 20–30 minutes — cook slightly faster, so subtract about 30–60 seconds from any doneness level. Cold eggs are also less likely to crack when lowered into boiling water, since the shell hasn't already warmed and expanded.
Boiling Eggs at High Altitude
Water boils at a lower temperature as elevation increases, so a "rolling boil" above roughly 3,000 feet (900 m) is actually cooler than sea-level boiling water. That gentler heat needs more time to fully set an egg, so add about 1 minute at 5,000 feet (1,500 m) and closer to 2–3 minutes at 7,000 feet (2,100 m) and above for any doneness level on the chart. A lid on the pot helps trap heat and keeps the timing closer to what a sea-level cook would expect.
How to Tell an Egg Is Done Without Cracking It Open
A hard-boiled egg spins smoothly and steadily on a countertop; a raw or soft-cooked egg wobbles because the liquid inside sloshes unevenly. For a definitive check, one egg from the batch can be cut open — the white should be fully opaque and the yolk should look the way the chart above describes for the doneness you're after. Since a home kitchen thermometer is impractical for a shelled egg, timing plus this spin test is the most reliable substitute.
Why Eggs Crack While Boiling — and How to Prevent It
Cracking happens when trapped air inside the shell expands faster than it can escape, usually because the egg went from very cold straight into a rolling boil, or because the water was boiling too violently. A pinhole pricked in the wide end of the shell with a pin lets air escape gradually, and adding a splash of vinegar to the water helps any egg white that does leak seal quickly instead of streaming out. A gentle boil rather than a violent one also reduces the shell-on-shell knocking that cracks eggs in a crowded pot.
Peeling — Why Fresh Eggs Are Harder to Peel
Very fresh eggs, laid within the last few days, cling to their shells because the inner membrane hasn't yet separated from the egg white. Eggs that are 7–10 days old peel far more cleanly. If only fresh eggs are on hand, an ice bath followed by rolling the egg gently on the counter to crackle the shell all over, then peeling under a thin stream of water, helps the shell lift away from the membrane.
Common Mistakes
- Skipping the ice bath lets residual heat keep cooking the egg for several more minutes, turning a planned jammy yolk into a fully hard one by the time it's peeled.
- Starting the timer before the water returns to a full boil after the eggs go in undercooks the whole batch by a minute or more.
- Crowding too many eggs into a small pot cools the water enough that it never truly returns to a boil, stretching every time on the chart.
- Using eggs straight from a very cold fridge into an aggressive boil is the single most common cause of cracked shells.
- Judging doneness by egg age or color instead of time and the spin test, which are far more reliable than guesswork.
Quick Answers
How long do you boil eggs for hard-boiled?
About 11–12 minutes in already-boiling water, or 12–14 minutes covered off heat using the cold-start method, followed immediately by an ice bath. For a soft, runny center suitable only for people at low risk of foodborne illness, 6 minutes is typical, well below the FDA's firm-set standard.
Why do my hard-boiled eggs have a green-gray ring around the yolk?
That ring is a harmless reaction between iron in the yolk and sulfur in the white, caused by overcooking or a slow cool-down. It doesn't affect safety, but an immediate ice bath after the timer ends prevents it almost entirely.
Can you boil eggs straight from the freezer?
No — whole eggs should never be frozen in the shell, since the liquid expands and cracks it, and USDA guidance covers only shelled or beaten eggs for freezing. Boil only fresh, refrigerated or room-temperature eggs in the shell.
Do boiled eggs keep cooking after you take them out of the pot?
Yes, residual heat trapped in the shell and yolk keeps cooking the egg for a minute or two unless it's moved to an ice bath immediately, which is why the ice bath step matters as much as the timer itself. See how boiled eggs keep once they're refrigerated for storage guidance after cooking.
