Knowing if eggs are properly cooked is an essential skill in the kitchen. Whether you’re making scrambled eggs for breakfast or baking a cake that requires several eggs, it’s important to know when they are cooked to perfection. Fortunately, there are several ways to test the doneness of eggs, and in this article, we will explore some of the most reliable methods.
One of the simplest ways to tell if eggs are cooked is by observing the color and consistency of the yolk and egg whites. For soft-boiled eggs, the yolk should be runny and the whites should be partially set. For hard-boiled eggs, the yolk should be fully set and the whites should be firm. However, this method is not foolproof, as some individuals prefer their eggs cooked differently.
To ensure that your eggs are fully cooked, you can also use a food thermometer to measure their internal temperature. For scrambled eggs and omelettes, the eggs should reach a minimum temperature of 160°F (71°C) to kill any potential bacteria. For hard-boiled eggs, the internal temperature should reach at least 170°F (77°C) for optimal doneness. This method is especially useful when making dishes that require cooking eggs to a specific temperature, such as custards or soufflés.
Floating test
The floating test is another method to determine if eggs are cooked. This test helps to assess the freshness of the eggs and can also indicate if they are undercooked or overcooked.

To perform the floating test, fill a bowl with cool water and gently place the egg into the water. If the egg sinks to the bottom and lies flat on its side, it is very fresh. Fresh eggs have less air inside them, causing them to sink.
If the egg stands upright or tilts slightly, it is still good to eat but not as fresh. As eggs age, they lose moisture and develop an air pocket, causing them to stand up or tilt in the water.
If the egg floats to the top of the water, it is no longer fresh and should be discarded. This indicates that there is a significant amount of air inside the egg, which means it has likely gone bad.
| Freshness | Result |
|---|---|
| Very fresh | Sinks to the bottom and lies flat on its side |
| Still good to eat, but not as fresh | Stands upright or tilts slightly |
| No longer fresh | Floats to the top of the water |
The floating test can be a useful tool when determining if eggs are cooked, especially if the eggs have been sitting in the refrigerator for some time or if their freshness is in question.
Egg white and yolk consistency test
One of the easiest ways to tell if eggs are cooked is by examining the consistency of the egg whites and yolks. This can give you a clue about how well the eggs are cooked and whether they are fully cooked or not.
To perform the egg white and yolk consistency test, start by cracking the egg open onto a plate or a flat surface. Carefully observe the egg white and yolk, making note of their texture and appearance.
Egg white consistency:
Egg whites that are cooked will have a firm and jelly-like consistency. They should be solid and not runny or watery. When you touch the egg white with a spoon or fork, it should hold its shape and not spread out easily.
On the other hand, if the egg white is still liquid or runny, it indicates that the egg is not fully cooked. It may need more time to cook to achieve the desired consistency.
Egg yolk consistency:
The consistency of the egg yolk can also give you an indication of its doneness. A fully cooked egg yolk will be firm and set, with a smooth texture. It should not be runny or liquid in any way.
If the egg yolk is still runny or liquid, it means that the egg is not fully cooked and may need more time to cook. However, some people prefer their egg yolks to be slightly runny, so this is a matter of personal preference.
Remember to always cook eggs thoroughly to reduce the risk of foodborne illnesses and to ensure their safety for consumption.
The tilt test
The tilt test is another method to determine if eggs are cooked. This test involves lifting the egg out of the water using a spoon or slotted spoon and tilting it slightly.
If the egg stands upright on the spoon or slotted spoon, it means that the egg is cooked to a hard-boiled stage. The yolk and white should be firm and set.
If the egg tilts slightly but doesn’t topple over, it means that the egg is cooked to a medium stage. The white should be firm and set, but the yolk will still be slightly runny.
If the egg topples over and the yolk runs out, it means that the egg is cooked to a soft-boiled stage. The white should be firm, but the yolk will be runny and partly cooked.
The tilt test is a quick and easy way to determine the doneness of eggs without cutting them open. However, it may not be as accurate as the other methods mentioned, so it’s always recommended to use a combination of tests to ensure the eggs are cooked to your desired level.
| Stage | Description |
|---|---|
| Hard-boiled | Upright on spoon, firm yolk and white |
| Medium | Tilted but doesn’t topple, firm white, slightly runny yolk |
| Soft-boiled | Toppled over, firm white, runny yolk |
The water test
To determine the doneness of an egg, the water test is a simple and effective method. This test works by observing the behavior of the egg when it is placed in water.
First, fill a saucepan with water and place it on the stove to boil. Carefully lower the egg into the boiling water using a spoon or tongs. Let the egg cook for a certain amount of time according to your desired level of doneness.
For a soft-boiled egg with a liquid yolk, cook the egg for about 4-6 minutes. For a medium-boiled egg with a slightly firm yolk, cook the egg for around 6-8 minutes. For a hard-boiled egg with a fully set yolk, cook the egg for about 9-12 minutes.
Once the cooking time has elapsed, carefully remove the egg from the boiling water and place it into a bowl of cold water. Let it cool down for a few minutes until it is comfortable to handle.
To check the doneness of the egg, gently spin it on a flat surface. If the egg spins easily and quickly, it is fully cooked. If it wobbles slightly or doesn’t spin at all, it is likely undercooked. If the egg spins but feels heavy and sluggish, it is probably overcooked.
Alternatively, you can gently tap the egg on a hard surface and observe the sound it makes. A fully cooked egg will make a solid and clear sound, while an undercooked or overcooked egg will produce a dull and muffled sound.
Using the water test is a reliable way to determine the doneness of an egg without cutting into it. It allows you to achieve the perfect level of doneness for your preferences, whether you prefer a soft, medium, or hard-boiled egg.
The temperature test
Another way to determine if eggs are cooked is by using the temperature test. This method involves using a food thermometer to measure the internal temperature of the egg. By doing so, you can ensure that the egg is cooked to the desired level of doneness and eliminate the risk of undercooking or overcooking.
Here’s how you can perform the temperature test:
- Start by inserting the food thermometer into the thickest part of the egg, avoiding contact with the shell or the yolk.
- Make sure that the thermometer is properly calibrated and reads accurately.
- For soft-boiled eggs, the internal temperature should reach around 145°F (63°C). This will result in a runny yolk and a tender egg white.
- For medium-boiled eggs, the internal temperature should be between 160°F and 165°F (71°C and 74°C). This will give you a yolk that is still slightly soft and a firmer egg white.
- For hard-boiled eggs, the internal temperature should reach 170°F (77°C) or higher. This will result in a fully cooked yolk and a firm egg white.
- Once the desired temperature is reached, remove the thermometer and promptly cool the egg under cold running water or in an ice bath to stop the cooking process.
By using the temperature test, you can ensure that your eggs are cooked to perfection and enjoy them without any concerns about food safety or taste.
The crack and check test
One popular way to determine if an egg is cooked is by performing the crack and check test.
To do this test, gently tap the egg on a hard surface and then peel back a small portion of the shell. Pay attention to the appearance of the egg white and yolk.
If the egg white is still runny and the yolk is liquid, it means that the egg is raw and not cooked. You may need to cook it for a longer time.
If the egg white is slightly firm and the yolk is still runny, it means that the egg is soft-boiled. It is cooked, but the yolk is still liquid. This is perfect for dishes like ramen or dipping toast.
If the egg white is completely firm and the yolk is slightly runny, it means that the egg is medium-boiled. It is partially cooked, and the yolk is creamy, making it ideal for dishes like salads or noodles.
If the egg white and yolk are both fully cooked and firm, it means that the egg is hard-boiled. It is fully cooked and can be used in various dishes or eaten on its own as a snack.
Remember to handle the eggs with care and dispose of them properly if they are raw or not cooked to your liking.
Q&A
How can I tell if an egg is fully cooked without cracking it open?
There are a few ways to tell if an egg is fully cooked without cracking it open. One method is to spin the egg on a flat surface – a fully cooked egg will spin smoothly and quickly, while a raw or undercooked egg will wobble. Another method is to gently shake the egg – a fully cooked egg will not make any noise, while a raw or undercooked egg will slosh around inside. Lastly, you can use the egg’s weight to determine its doneness – a fully cooked egg will feel heavier than a raw egg due to the moisture loss during cooking.
How can I tell if a boiled egg is soft or hard without cutting into it?
If you don’t want to cut into a boiled egg to determine its doneness, you can try the following methods. First, you can give the egg a gentle squeeze – a soft-boiled egg will feel slightly soft and give under pressure, while a hard-boiled egg will feel firm and not give at all. Another way is to spin the egg on a flat surface – a soft-boiled egg will spin slowly and wobble, while a hard-boiled egg will spin smoothly and quickly. Lastly, you can try shaking the egg – a soft-boiled egg will make a sloshing sound, while a hard-boiled egg will not make any noise.
What is the best method to check the doneness of fried eggs?
The best method to check the doneness of fried eggs is to observe the appearance of the whites and the yolk. For a sunny-side-up egg, where the yolk is not cooked through, the whites should be set and opaque, while the yolk should still be runny. For an over-easy or over-hard egg, where the yolk is fully cooked, the whites should be set and opaque, and the yolk should be cooked to your desired level of doneness. You can also touch the yolk gently with a spatula to check its firmness – a runny yolk will feel soft, while a fully cooked yolk will feel firm.
What is the proper way to check if poached eggs are done?
There are a few ways to check the doneness of poached eggs. You can gently touch the top of the egg with a spoon – a runny egg will feel soft, while a fully cooked egg will feel firm. Another method is to gently lift the egg out of the water with a slotted spoon and give it a small shake – a runny egg will jiggle and appear loose, while a fully cooked egg will not move much. Lastly, you can carefully cut into the egg with a knife to check the consistency of the yolk – a runny yolk will be liquidy, while a fully cooked yolk will be slightly firm.
How can I tell if scrambled eggs are cooked without tasting them?
If you don’t want to taste scrambled eggs to check if they are cooked, there are a few visual cues to look for. Cooked scrambled eggs should appear fluffy and set, with no visible liquid egg remaining. They should have a light golden color and a slightly firm texture. You can use the edge of a spatula to gently lift a portion of the eggs from the pan – if they hold their shape and don’t leave any liquid behind, they are likely fully cooked. Additionally, you can touch the scrambled eggs lightly with a spatula or fork – if they feel springy and not runny, they are likely done.
