If boiling eggs have ever posed a herculean task before you, then, you certainly need to read this article.  

Can you boil eggs for too long?

Yes. It is possible to boil eggs for too long. Boiling eggs for 10 to 12 minutes makes them overcooked and they’ll become hard-boiled eggs. Cooking eggs beyond this time can make them toxic to your health.

How long should you boil eggs?

Boil eggs for 5 to 12 minutes. How long you boil eggs depends on the size of the eggs and the result you want to get. That is, it depends on how soft or hard you want the eggs to be.

When you boil medium-sized eggs for 5 to 6 minutes, you will have a runny yolk that is perfect for dipping or for garnishing a crunchy salad. Boiling eggs for 7 to 8 minutes gives you a sticky or jammy yolk with a firm white. This type of egg is great for toast, ramen, and salad.

After 8 minutes, the eggs become firmer, hard-boiled, and perfect for a snack, slicing over meals and refrigerating for later use.

How do you know eggs are done boiling?

Any of the following ways can help you identify eggs that are well-cooked. You need only one out of the eggs you’re boiling.

1. The spin method

Take the egg out of the boiling water and allow it to cool a little. Afterward, place it on a flat surface like the kitchen counter and give it a spin.

If the egg spins easily without wobbling, then, it’s done boiling. If it wobbles, it means there’s still some liquid in the egg and you may need to boil it again, if you want firm eggs.

2. Read the temperature of the egg

Get an instant-read thermometer and check the temperature of the egg. When eggs are firm and ready to eat, they should have an internal temperature of 158°F or 160°F. However, before you do this method, you should allow the egg to rest for 15 to 30 seconds.

3. The light test

When you hold a raw egg up to the light, the light passes through and allows you to see the yolk in the egg. But a cooked egg is solid and does not allow light through it. If you can see through an egg that you’ve been boiling, you need to cook it again.

4. Test for bubbles in the water

When you drop a raw egg in warm water, small bubbles form in the water. On the other hand, a cooked egg will not cause any bubbles to form.

5. Peel the egg

This is the most reliable method but before you go for this option, you have to be confident that you have boiled the eggs well. Otherwise, you risk losing or wasting an egg. Moreover, this should be your go-to method if you’re in doubt.

Cool the egg in cold water and peel off the shell. You can cut it open to see if the yolk is firm enough. If you’re satisfied, you can take out the remaining eggs.

What should you do if you have boiled eggs too long?

If you realize that you have boiled eggs too long, remove the pot from the heat, take out the eggs and plunge them into a bowl of cold water or ice. This will stop the cooking process and may prevent eggs from developing the grey hue around the yolk.

However, if you don’t like what you see when you crack the eggs, turn them into new meals. For instance, you can use them to make an egg salad sandwich.

How do you know eggs are overboiled?

When you crack overboiled eggs, they feel very firm and the yolks have a grey coating. This color is a result of a toxic compound, ferrous sulfide, that forms from the compounds released from the egg’s white and yolk.

When eggs boil too long, they release these compounds – hydrogen sulfide and iron – which are responsible for the formation of ferrous sulfide. Ferrous sulfide is what forms the greyish hue you see over the yolk or hard-boiled and overcooked eggs.

Yes, you can. Eating eggs that are boiled for too long is quite normal, especially because some people prefer their eggs this way – hard-boiled and moderately overcooked.

However, it is not advisable to consume too much of it because too much ferrous sulfide can be toxic.
