A soft-boiled egg has a fully set white with a warm, runny yolk. The window between a perfect soft-boil and an accidental medium-boil is narrow — just 60–90 seconds. This makes a precise timer essential. Lower the eggs into gently boiling (not violently boiling) water for the most consistent results.

Six minutes from boiling water produces the ideal soft-boiled egg: the white is completely firm and opaque, while the yolk is warm, liquid, and golden. Transfer immediately to ice water to halt cooking — leaving the egg in hot water even 30 seconds longer will push the yolk toward medium-boiled.

The window is about ninety seconds wide

Between a white that has not set and a yolk that has, there is roughly a minute and a half of usable range. That narrowness is the entire difficulty — nothing else in everyday cooking punishes a thirty-second error this visibly.

It is also why soft-boiling rewards a timer over judgement in a way that, say, roasting does not. There is no way to check without opening the egg, and opening it is the outcome.

Six minutes, and what moves it

Six minutes for a fridge-cold large egg into boiling water is the reliable starting point for a set white and a runny yolk. Room temperature takes it to about five; a medium egg takes off another thirty seconds.

Altitude matters too and is the variable nobody checks. Water boils cooler as you go up, so the same six minutes at 1,500 metres produces a noticeably softer egg than at sea level.

Peeling a soft egg is its own problem

Very fresh eggs are hardest to peel, which is the opposite of what most people assume. Eggs a week or two old separate from the shell far more easily, so if peeling matters, buy ahead rather than buying fresh.

For a soft egg the gentler option is not to peel at all — into an egg cup, top off with a knife, eat with a spoon. Peeling a six-minute egg intact takes practice that a teaspoon makes unnecessary.

Large eggs lowered into boiling water. The usable window is narrow — a stopwatch beats judgement here.

Soft-boiled timing
Egg	Time	Result
Large, from fridge	6 min	Set white, runny yolk
Large, room temperature	5 min	Set white, runny yolk
Medium, from fridge	5:30	Set white, runny yolk
Large, jammy instead	7 min	Thick, spoonable yolk
Large, very soft	4:30	Barely set white
At altitude	+30-60 s	Water boils cooler

The whole usable range is about ninety seconds wide, which is why a thirty-second error shows.
Very fresh eggs are the hardest to peel. Week-old eggs separate from the shell far more easily.

❓ Frequently Asked Questions

How long should I boil an egg for soft-boiled?

6 minutes from boiling water produces the classic soft-boiled egg with a fully set white and runny yolk. For a slightly firmer yolk (still liquid in center but less runny), try 6 minutes 30 seconds. For a very runny white too, try 5 minutes 30 seconds.

Why did my soft-boiled egg white come out runny?

A runny white means the egg was undercooked — under 5 minutes typically. This can also happen if eggs were taken directly from a very cold refrigerator (add 30–45 seconds for cold eggs), if the water was at a rolling boil rather than a gentle simmer, or if the eggs were very large.

How do I peel a soft-boiled egg without breaking it?

Ice the egg for exactly 5 minutes after cooking — no more, as eggs become harder to peel when very cold. Gently crack the wide end (air pocket), peel under a thin stream of cold water, and remove the shell in large sections starting from the cracked wide end.

Can I soft-boil an egg in the microwave?

Microwaving eggs in shell is not recommended — pressure builds inside and can cause them to explode. To microwave an egg, crack it into a microwave-safe container with a lid, add a tablespoon of water, and microwave on 50% power for 60–90 seconds, checking every 20 seconds.

How do I know when the water is at the right temperature for soft-boiling?

Use a gentle boil: small bubbles rising continuously but not violently churning. A violent rolling boil cracks delicate egg shells and can cause uneven cooking from the outside impact. Bring to a full boil, then reduce to medium heat before adding eggs.

Can I prepare soft-boiled eggs in advance?

Yes. Cook soft-boiled eggs, transfer to ice water, peel, and refrigerate unpeeled for up to 2 days. Reheat by placing in a bowl of very hot (not boiling) water for 1–2 minutes. Do not reheat in boiling water — this overcooks the yolk.

What is the difference between soft-boiled and poached?

Both produce eggs with set whites and runny yolks. Soft-boiled eggs cook in their shell in boiling water; poached eggs cook without the shell in simmering water. Poached eggs have a more delicate texture and no shell to deal with, but require more technique to execute consistently.

How many calories are in a soft-boiled egg?

One large soft-boiled egg contains approximately 70–77 calories: 5g protein, 5g fat, and less than 1g carbohydrate. The cooking method (soft vs. hard-boiled) does not significantly change caloric content — calories in an egg are fixed regardless of how it is cooked.
