How Long to Boil an Egg: A Tested Timing Chart (Soft, Medium & Hard)
Soft, jammy, or hard — the exact minutes for perfect boiled eggs, tested in our kitchen. A clear timing chart for large eggs, plus adjustments for egg size, altitude and batch size, and the ice-bath trick that stops the grey yolk ring.
There is a strange amount of disagreement about something as simple as boiling an egg. Ask five people and you will get five answers — and most of them are vague ("about ten minutes?"). The truth is that a boiled egg is one of the most precise things you can cook. The difference between a runny, dippable soft-boiled egg and a chalky, grey-ringed hard-boiled one is just a few minutes in the same pot of water.
So we did the careful work for you. In the ClockAura kitchen we boiled dozens of large eggs straight from the fridge, lowering them into already-boiling water and pulling them at exact one-minute intervals, then cut every single one in half to record what the yolk really looked like. The chart below is the result. Set our free egg timer to the time you want, and you will get the same egg every time.
The quick answer: egg boiling times at a glance
These times are for large, fridge-cold eggs lowered into boiling water, then held at a gentle simmer. Pull the egg the second the timer sounds and move it straight to an ice bath.
| Time | Result | Best for | |------|--------|----------| | 4 min | Very runny — liquid yolk, just-set white | Dipping with toast soldiers | | 6 min | Soft-boiled — molten centre, set white | Spooning from the shell, ramen | | 7 min | Jammy — fudgy, bright orange centre | Ramen eggs, salads, grain bowls | | 8 min | Medium — creamy but no longer runny | Niçoise salad, snacking | | 10 min | Hard-boiled — tender, fully set, no grey ring | Egg salad, slicing, lunchboxes | | 12 min | Firm hard-boiled — sturdy and dry | Deviled eggs, mashing, transport |
If you only remember two numbers, make them 6 and 10: six minutes for a soft, spoonable egg, ten minutes for a proper hard-boiled egg that still has a golden — not grey — yolk.
Our method: boil from boiling, not from cold
You will see two camps online. One starts eggs in cold water and brings the whole pot up to a boil; the other lowers eggs into water that is already boiling. We tested both, and for everyday cooking we strongly prefer the boiling-water start for three reasons:
- Timing is repeatable. With a cold start, your cooking time depends on how fast your particular stove heats your particular pot — so "bring to a boil, then 7 minutes" means something different in every kitchen. Lowering eggs into boiling water starts the clock at a known temperature, which is exactly why this chart works for you and not just for us.
- The eggs peel more easily. A blast of immediate heat helps the white pull away from the membrane.
- You get a wider doneness window. Soft-boiled eggs are nearly impossible to nail with a cold start.
Here is the routine we used for every egg in the chart:
- Bring a saucepan of water to a rolling boil — enough to cover the eggs by about an inch.
- Lower the eggs in gently with a slotted spoon so they do not crack on the bottom.
- Reduce the heat to a gentle simmer (a hard boil bounces the eggs around and cracks them).
- Start your egg timer the moment the last egg is in.
- When it sounds, move every egg straight into a bowl of ice water.
Adjust for your eggs and your kitchen
The chart assumes large, fridge-cold eggs at roughly sea level. Real kitchens vary. Here is how to adjust.
Egg size
Bigger eggs need more time because the heat has further to travel to the centre.
| Egg size | Adjustment | |----------|------------| | Medium | Subtract about 1 minute | | Large (chart default) | No change | | Extra-large / Jumbo | Add about 1 minute |
Fridge-cold vs room temperature
Our chart uses cold-from-the-fridge eggs, because that is how most people actually cook. If your eggs are at room temperature, take about 30–60 seconds off the time. Room-temperature eggs are also less likely to crack from thermal shock when they hit the hot water.
Altitude
Water boils at a lower temperature the higher you live, so eggs cook more slowly, not faster. As a rough guide:
| Elevation | Adjustment | |-----------|------------| | Up to ~3,000 ft (900 m) | No change | | 3,000–6,000 ft (900–1,800 m) | Add ~1 minute | | Above 6,000 ft (1,800 m) | Add ~2–3 minutes |
If you live somewhere high, treat the chart as a starting point and cut one egg open to calibrate — then you will know your number forever.
How many eggs are in the pot
A dozen cold eggs will drop the water temperature far more than two will. For a big batch, let the water return to a gentle simmer before you trust the timer, or simply add about 30 seconds. Always use a pot big enough for the eggs to sit in a single layer.
The ice bath: the step most people skip
This is the single biggest upgrade to your eggs, and it costs nothing. The moment the timer sounds, plunge the eggs into a bowl of cold water with ice.
It does two things. First, it stops the cooking immediately — eggs hold a lot of heat and keep cooking in their own shell on the counter, which is how a perfect 10-minute egg turns into an overcooked one by the time you peel it. Second, the rapid cooling contracts the egg slightly inside the shell, which makes peeling dramatically easier. Leave them in the ice bath for at least five minutes. Need a hand keeping track? A quick 5-minute timer is perfect for the chill.
How to peel a boiled egg cleanly
Even with a good method, some eggs fight back. A few things genuinely help:
- Use slightly older eggs. Very fresh eggs are notoriously hard to peel; eggs that are a week or two old peel far more cleanly.
- Crack and roll. Tap the egg all over and roll it gently under your palm to craze the shell into small pieces.
- Peel under running water. A thin stream gets under the membrane and floats the shell off.
- Start at the fat end. There is a small air pocket there that gives you a flap to grab.
Why does my yolk have a grey-green ring?
That ring is the classic sign of an overcooked egg. When an egg cooks too long or too hot, sulphur in the white reacts with iron in the yolk to form iron sulphide at the boundary — harmless, but a little chalky and faintly sulphurous. You avoid it the same two ways every time: do not over-boil (stick to the chart), and use the ice bath to halt carry-over cooking the instant the timer goes off. A 10-minute egg that is iced immediately stays golden; the same egg left to cool on the counter often greys.
Frequently asked questions
Should I start the timer before or after the eggs go in?
After — start it the moment the last egg is in the simmering water. The chart is built around that exact start point, which is why a precise tool like the ClockAura egg timer matters more here than a rough guess.
Does the egg timer keep running if I switch tabs or lock my phone?
Yes. ClockAura's timer is time-based, not tick-based, so it stays accurate even when the browser tab is in the background or your screen sleeps, and it sounds an alarm when the time is up. You do not need to keep the tab in front of you while you set the table.
How long do boiled eggs last?
Hard-boiled eggs keep for about a week in the fridge, and they last longest if you leave them unpeeled until you are ready to eat them. Once peeled, eat them within a day or two.
Can I boil a cracked egg?
You can rescue an egg that cracks in the pot by adding a splash of white vinegar to the water — it helps the leaking white set quickly instead of streaming everywhere. It is not pretty, but it works in a pinch.
What if I cook eggs all the time?
Save your go-to times as a set. Our cooking preset collection keeps your favourite durations one tap away, and round numbers like the 10-minute timer are handy for batch-boiling.
Boil it perfectly, every time
A great boiled egg is not luck — it is a temperature and a number of minutes. Pick your doneness from the chart, start your eggs in boiling water, set the egg timer to match, and finish with an ice bath. Do that and you will never again poke a hopeful spoon into a mystery egg. Bookmark this page, keep the timer handy, and the next perfect egg is exactly six (or ten) minutes away.
