What Is the Healthiest Way to Cook and Eat Eggs?

Eggs are a cheap but incredibly nutritious food.

They contain relatively few calories, but they’re packed with:

  • proteins
  • vitamins
  • minerals
  • healthy fats
  • various trace nutrients

That said, the way you prepare your eggs can affect their nutrient profile.

This article explores the healthiest ways to cook and eat eggs.

A review of the different cooking methods

Eggs are delicious and extremely versatile.

They can be cooked in many different ways and are easy to combine with other healthy foods, like vegetables.

Cooking them also destroys any dangerous bacteria, making them safer to eat.

Here’s a breakdown of the most popular cooking methods:

Boiled

Hard-boiled eggs are cooked in their shells in a pot of boiling water for 6–10 minutes, depending on how well cooked you want the yolk to be.

The longer you cook them, the firmer the yolk will become.

Poached

Poached eggs are cooked in slightly cooler water.

They’re cracked into a pot of simmering water between 160–180°F (71–82°C) and cooked for 2.5–3 minutes.

Fried

Fried eggs are cracked into a hot pan that contains a thin layer of cooking fat.

You can then cook them “sunny side up,” which means the egg is fried on one side, or “over easy,” which means the egg is fried on both sides.

Baked

Baked eggs are cooked in a hot oven in a flat-bottomed dish until the egg is set.

Scrambled

Scrambled eggs are beaten in a bowl, poured into a hot pan, and stirred over low heat until they set.

Omelet

To make an omelet, eggs are beaten, poured into a hot pan, and cooked slowly over low heat until they’re solid.

Unlike scrambled eggs, an omelet isn’t stirred once it’s in the pan.

Microwaved

Microwaves can be used to cook eggs in many different ways. It takes much less time to cook eggs in a microwave than it does on a stove.

However, it’s usually not a good idea to microwave eggs that are still inside their shells. This is because pressure can quickly build up inside them, and they may explode.

Cooking makes some nutrients more digestible

Cooking eggs makes them safer to eat, and it also makes some of their nutrients easier to digest.

One example of this is the protein in eggs.

Studies have shown it becomes more digestible when it’s heated

In fact, one study found that the human body could use 91% of the protein in cooked eggs, compared to only 51% in raw eggs.

This change in digestibility is thought to occur because heat causes structural changes in the egg proteins.

In raw eggs, the large protein compounds are separate from each other and curled up in complex, twisted structures.

When the proteins are cooked, heat breaks the weak bonds that hold them in shape.

The proteins then form new bonds with other proteins around them. These new bonds in the cooked egg are easier for your body to digest.

You can see these changes occurring as the egg white and yolk change from a thick gel to rubbery and firm.

The protein in raw eggs can also interfere with the availability of the micronutrient biotin.

Eggs are a good source of biotin, which is an important nutrient used in fat and sugar metabolism. It’s also known as vitamin B7, or vitamin H.

In raw eggs, a protein in the egg whites called avidin binds to biotin, making it unavailable for your body to use.

However, when eggs are cooked, the heat causes structural changes to avidin, making it less effective at binding to biotin. This makes biotin easier to absorb.

5 tips to cook super healthy eggs

Eggs are nutritious, but you can make your eggs even healthier.

Here are five tips to cook super healthy eggs:

1. Choose a low-calorie cooking method

If you’re trying to cut back on calories, choose poached or boiled eggs.

These cooking methods don’t add any extra fat calories, so the meal will be lower in calories than fried or scrambled eggs or an omelet.

2. Combine them with vegetables

Eggs go really well with vegetables.

This means that eating eggs is a great opportunity to boost your vegetable intake and add extra fiber and vitamins to your meal.

Some simple ideas include adding the vegetables of your choice into an omelet or scrambled eggs, like in this recipe.

Or simply cook the eggs whichever way you want and have vegetables on the side.

3. Fry them in an oil that’s stable at high temperatures

The best oils for cooking at high heat, like when pan-frying, are those that remain stable at high temperatures and don’t oxidize easily to form harmful free radicals.

Examples of good choices include avocado oil and sunflower oil. If using extra-virgin olive oil or coconut oil, it’s best to cook at temperatures lower than 410°F (210°C) and 350°F (177°C), respectively.

4. Choose the most nutritious eggs you can afford

A number of factors, including the farming method and chicken’s diet, can influence the nutritional quality of eggs.

In general, pasture-raised and organic eggs are thought to be nutritionally superior to caged and conventionally produced eggs.

This article goes into detail about the nutritional differences between eggs produced by different methods.

5. Don’t overcook them

The longer and hotter you cook your eggs, the more nutrients you may lose.

Using higher heat for longer may also increase the amount of oxidized cholesterol they contain, which is particularly true of pan-frying.

The bottom line

Overall, shorter and lower-heat cooking methods cause less cholesterol oxidation and help retain most of the egg’s nutrients.

For this reason, poached and boiled (either hard or soft) eggs may be the healthiest to eat. These cooking methods also don’t add any unnecessary calories.

All that being said, eating eggs is generally super healthy, no matter which way you cook them.

So you may just want to cook and eat them in the way you enjoy the most and not obsess over the small details.
