Calculator
Hen Egg Boiling Time Calculator
Select your egg’s starting temperature and how you want the yolk. Times are counted from when the water returns to a gentle boil after adding the eggs.
Cooking temperature: water at a gentle boil (95 to 100°C / 203 to 212°F). How to time: start counting from when the water returns to a gentle boil after you lower the eggs in.
These times are for large hen eggs (approximately 60 g). Cool eggs in cold water immediately after cooking.
Egg size, altitude, and water hardness all affect the exact result. Use these times as a guide and adjust by 30 seconds in either direction to match your stove and preference.
Doneness
Soft, Jammy, or Hard — What Is the Difference?
Egg white proteins set at around 63°C / 145°F and are fully firm above 80°C / 176°F. Yolk proteins start thickening at around 65°C / 149°F and become fully set near 70°C / 158°F. This narrow window is why a single minute changes the result dramatically.
- Soft-boiled (2–3 min): the white is barely set near the yolk, which flows freely when cut. Eat immediately from the shell with a spoon or dip toast soldiers.
- Jammy or medium (5–6 min): the white is fully set and the yolk is warm, fudgy, and deeply orange. Ideal for ramen, grain bowls, and toast.
- Hard-boiled (9–10 min): white and yolk are fully firm. Good for deviled eggs, egg salad, sandwiches, and anything that needs to hold its shape. Do not go beyond 11 minutes or a green-grey ring appears around the yolk.
Preparation
How to Prepare Hen Eggs Before Cooking
Rinse eggs under cool running water before cooking. Check each egg for cracks — a cracked egg will lose white into the water and may fall apart.
Starting temperature matters. Eggs taken straight from the fridge are significantly colder at the center, so they need 1 to 2 extra minutes compared to eggs at room temperature. For the most predictable results, remove eggs from the refrigerator 10 to 15 minutes before cooking.
Add a pinch of salt or a splash of white vinegar to the cooking water. Salt raises the boiling point slightly and is believed to help reduce cracking. Vinegar can help the white coagulate quickly if a shell does crack, containing any leakage.
Method
How to Boil Hen Eggs Step by Step
- Bring a pot of water to a gentle boil. Use enough water to cover the eggs by at least 2 cm / 1 inch.
- Add a pinch of salt. Optionally add a splash of white vinegar.
- Lower eggs one at a time using a large spoon or slotted spoon. Do not drop them.
- Start timing when the water returns to a gentle boil. Keep the heat at medium so it does not boil too hard.
- Cook for the time matching your desired doneness. See the chart below.
- Remove eggs with a slotted spoon and transfer to a bowl of cold water.
- Leave in cold water for at least 3 to 4 minutes before peeling. For hard-boiled eggs, this is important for easy peeling.
- Peel under running water, starting at the wider end where the air pocket sits.

Hen Egg Cooking Time Chart
Times are from when the water returns to a gentle boil after the eggs are added. These are for large eggs (around 60 g).
| Doneness | Room-temp egg | Fridge-cold egg | Result |
|---|---|---|---|
| Soft-boiled | 2–3 minutes | 3–4 minutes | Runny yolk, just-set white near yolk |
| Jammy / medium-soft | 5–6 minutes | 6–7 minutes | Fudgy, flowing orange yolk |
| Medium-hard | 7–8 minutes | 8–9 minutes | Mostly set yolk with slight softness in center |
| Hard-boiled | 9–10 minutes | 10–11 minutes | Fully set white and yolk |
| Overcooked | 12+ minutes | 13+ minutes | Green-grey ring, rubbery white, chalky yolk |
Safety
Doneness and Food Safety
Hard-boiled hen eggs are safe for everyone. The white and yolk are fully cooked and reach temperatures well above 70°C / 160°F during boiling.
Food safety note: soft-boiled and jammy eggs have a partially cooked or liquid yolk. For healthy adults this is generally considered safe when using fresh, clean eggs. However, pregnant women, young children, the elderly, and people with weakened immune systems should only eat fully hard-boiled eggs (white and yolk both completely set) to avoid the small risk of Salmonella.
Problem solver
Why Is There a Green Ring Around the Yolk?
A green-grey ring around the yolk is a sign of overcooking. It forms when hydrogen sulfide from the white reacts with iron in the yolk at high temperatures. It is completely harmless but gives a slightly sulphurous smell and a chalky texture.
To avoid it: do not cook hard-boiled eggs beyond 10 to 11 minutes and transfer them to cold water immediately after cooking. If you are cooking many eggs or have a powerful stove, err on the side of less time and check one egg by cutting it open.
Technique
Cold Water Start vs Boiling Water Start
Lowering eggs into already-boiling water gives the most consistent and predictable results because the timing starts from a fixed point. It is the method professional cooks use when they want a specific doneness every time.
A cold-water start (eggs in cold water, then brought to a boil) is more forgiving for hard-boiled eggs — there is less risk of cracking — but timing is unpredictable because it depends on your stove, the amount of water, and the pot. For soft or jammy eggs, always use a boiling-water start.
Chef tip
Why Are Fresh Eggs Harder to Peel?
Very fresh eggs have a lower pH in the white, which causes it to bond tightly to the inner membrane. As an egg ages (5 to 10 days), the pH rises and the bond loosens, making peeling much easier. If you know you will be making hard-boiled eggs, buy them 5 to 7 days before cooking. If you only have very fresh eggs, peel them under running water and the stream helps lift the membrane away from the white.
Avoid this
Common Mistakes
- Dropping cold fridge eggs directly into hard-boiling water, which causes cracking.
- Boiling at a hard rolling boil — the eggs bounce around and crack against each other.
- Forgetting to transfer to cold water, so the eggs keep cooking after they leave the pot.
- Overcooking beyond 11 minutes, which creates the green ring and chalky texture.
- Starting to time before the water returns to a boil after you add the eggs.
Rescue tips
How to Fix Undercooked or Overcooked Eggs
- Undercooked soft-boiled eggReturn to simmering water for 60 to 90 seconds. The yolk will firm up quickly, so watch carefully.
- Overcooked hard-boiled eggNothing reverses overcooking, but a chopped or mashed overcooked egg mixed with mayonnaise, mustard, and seasoning is still excellent as a sandwich filling or deviled egg filling.
Serving
What to Serve With Boiled Hen Eggs
Soft-boiled eggs go beautifully with buttered toast soldiers, a sprinkle of flaky salt, and freshly ground pepper. Jammy eggs are excellent in ramen, rice bowls, and grain salads. Hard-boiled eggs are ideal with boiled potatoes, pickled vegetables, radishes, anchovies, sautéed mushrooms, and smoked fish. They are a cornerstone of vegetable-based salads like Niçoise.
Simple recipe
Perfect Soft-Boiled Eggs With Toast Soldiers

Leftovers
How to Store and Reheat Boiled Hen Eggs
Hard-boiled eggs in the shell keep well in the refrigerator for up to 1 week. Store them unpeeled to preserve moisture. Peeled eggs should be kept in an airtight container or submerged in cold water (change water daily) and used within 5 days.
Soft-boiled and jammy eggs are best eaten fresh. If you need to store them, keep them unpeeled in the fridge for up to 2 days and reheat by placing them back in hot (not boiling) water for 1 to 2 minutes.
Do not freeze boiled eggs. The white becomes tough and watery when frozen and thawed.

Questions
FAQ
How long do you boil hen eggs?
Soft-boiled hen eggs take 2 to 3 minutes from when the water boils. Jammy or medium eggs take 5 to 6 minutes. Hard-boiled eggs take 9 to 10 minutes. Add 1 to 2 minutes if the eggs come straight from the fridge.
Should I start eggs in cold or boiling water?
For precise timing and consistent results, lower eggs into already-boiling water and start timing when the water returns to a gentle boil. A cold-water start makes timing less predictable because heating time varies with pot size and stove power.
Why do my hen eggs crack when boiling?
Eggs crack when dropped into hot water from cold, when the water boils too hard, or when there is an air pocket near the shell. Let eggs warm slightly before cooking, lower them gently with a spoon, add a pinch of salt to the water, and keep the pot at a gentle boil rather than a hard rolling boil.
How do I peel hard-boiled eggs easily?
Transfer eggs to cold water immediately after cooking and let them sit for at least 3 to 4 minutes. Peel under running water, starting at the wider end where the air pocket is. Fresh eggs are harder to peel than eggs that are 5 to 7 days old.
Why do hard-boiled eggs get a green ring around the yolk?
The green-grey ring forms when eggs are overcooked or left sitting in hot water too long. It is a reaction between sulfur in the white and iron in the yolk. It is harmless but affects texture and flavor. To avoid it, do not cook hard-boiled eggs beyond 10 to 11 minutes and cool them quickly in cold water.
Can I boil hen eggs from frozen?
Raw hen eggs should not be frozen in their shells. If you have cracked and frozen eggs, thaw them completely in the refrigerator before using. Frozen raw eggs are best scrambled or used in baking, not boiled.
How long do hard-boiled eggs last in the fridge?
Hard-boiled eggs in the shell last up to 1 week in the refrigerator. Peeled hard-boiled eggs should be stored in a bowl of cold water (change it daily) or in an airtight container and used within 5 days. Do not leave boiled eggs at room temperature for more than 2 hours.
Does the size of the egg affect cooking time?
Yes. Small or medium eggs may be done 30 to 60 seconds faster than large or extra-large eggs. The times given on this page are for large eggs (around 60 g). Adjust by 30 to 60 seconds for significantly smaller or larger eggs.
