How Long to Cook Hard-Boiled Eggs (Because Timing Is Everything)

by

Hard-boiled eggs are a kitchen staple—perfect as a protein-rich snack, the foundation of deviled eggs, or a reliable addition to salads and meals. Yet getting them just right can be surprisingly tricky. The ideal hard-boiled egg has tender whites and a fully cooked, creamy yolk. Cook them too long and you’ll end up with rubbery whites and dry, crumbly yolks. Cook them too little and the centers remain runny. The secret to success lies in timing and a few simple details.

Egg Size and Cooking Time

Egg size plays a major role in determining how long your eggs should cook. Most recipes assume large eggs, but even a small size difference can affect the final result.

Here’s a general timing guide based on egg size:

  • Medium eggs: 8–10 minutes

  • Large eggs: 10–12 minutes

  • Extra-large eggs: 12–14 minutes

Pro tip: If you like your yolks slightly soft in the center rather than completely firm, reduce the cooking time by about one minute.

Factors That Influence Cooking Time

Several variables can subtly change how long eggs need to cook:

  • Egg temperature: These times assume the eggs are cold straight from the refrigerator. Eggs at room temperature will cook a bit faster.

  • Number of eggs: Cooking a large batch may add a minute or two, as the water temperature drops slightly when the eggs are added.

  • Water level: Eggs should be covered by about 1–2 inches of water. Too little water can lead to uneven cooking.
