Egg Nutrition 101: The Healthiest Way to Cook Eggs
"An egg is always an adventure; the next one may be different."
—Oscar Wilde
Eggs are a nutritional powerhouse, packed with essential nutrients like protein, vitamins, and minerals. Yet how you cook the egg may negate the health benefits found in those eggs.
When cooking that fragile egg, it’s important to consider the cooking fat/medium, the pan, the cooking surface, the types of eggs you use, and even the amount of heat and length of time you’re cooking the eggs for.
This article will guide you through the best cooking methods to ensure you get the most out of these incredible superfoods. By making a few simple changes in your cooking techniques, you can maximize egg health and enjoy their full nutritional benefits. Plus, I’ll provide five simple ways to cook eggs.
Health Considerations When Cooking Eggs
There are three main factors to consider when trying to make the healthiest version of eggs: the type, the medium used, and the cooking method.
Which Are The Healthiest Eggs To Use?
The types of eggs:
Conventional eggs come from chickens who are confined to cages. They’re fed grains, legumes, and other foods that are allowed to be genetically modified and which may contain pesticides. These conventional chickens are also given antibiotics which make its way into your omelet at home.
Pasture-raised eggs, sourced from chickens with outdoor space, offer better living conditions and more nutritious eggs than those who are in the standard henhouses. These better environments mean higher levels of omega-3 fatty acids, vitamin E, and beta-carotene compared to conventional eggs.
Organic eggs, meanwhile, come from chickens raised on pesticide-free, non-GMO vegetarian diets with minimal antibiotic use.
While free-range eggs are a reasonable option, they may not consistently deliver the same nutritional benefits as pasture-raised or organic eggs.
The bottom line: For the healthiest eggs, choose pasture-raised and organic varieties. For a deeper dive on egg choices, read this: What Are The Healthiest Eggs: Pasture-Raised, Free-Range, or Organic?
Which Oil Is Best To Use With Eggs?
The choice of cooking fats, such as butter, olive oil, or avocado oil, plays a crucial role in preparing nutritious and delicious eggs. These natural fats offer a spectrum of advantages which impact both the flavor and nutritional profile of your meal.
Butter, for instance, adds a rich, creamy taste to your eggs, elevating their overall palatability. Moreover, it contains essential fatty acids and fat-soluble vitamins like A, D, and K2. This is my go-to cooking medium for eggs because of its flavor. Go with a grass-fed butter such as Kerrygold. I also love ghee for its even better, butter-ier flavor but we rarely get this because of how much it costs.
Tip: When eating out, ask the server to cook your food in butter. Most of the time they are using some version of a seed oil such as canola oil so avoid these toxins (more on this below) by asking for butter.
Similarly, extra-virgin olive oil (EVOO) and avocado oil not only provide a unique flavor profile but also contribute heart-healthy monounsaturated fats, which are known for their potential to reduce the risk of heart disease and improve overall health. These oils can help in better absorption of fat-soluble vitamins present in eggs. While EVOO is delicious, I only use it on my eggs when those eggs are being combined with another food such as my salad (yes, I do that) because of the rich flavor. Avocado oil tends to be my next favorite egg-cooking medium (behind butter) because it has a more neutral flavor.
Primal Kitchen is one of our favorite brands for cooking oils (EVOO, avocado oil, coconut oil) as well as healthy condiments. You can check out their site and use the promo code MINDBODYDAD for a 10% discount.
On the contrary, the use of seed oils like margarine in cooking eggs raises many health concerns. These seed oils, often called vegetable oils, have been shown to increase your risk of heart disease, Alzheimer’s, obesity, cholesterol issues, and even depression.

The bottom line: Use butter or avocado oil when cooking eggs.
The Healthiest Pans For Cooking Eggs
Eggs can be messy and cleaning that pan afterwards can be brutal. It makes sense why so many people want to use cheap and easy-to-clean non-stick cookware. While convenient, non-stick surfaces raise significant health concerns due to the presence of perfluoroalkyl substances (PFAS), particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). These chemicals are used in the production of non-stick surfaces, and over time, they can break down and release harmful toxins when exposed to high temperatures. Research has linked PFAS exposure to various health issues, including an increased risk of cancer, heart disease, and elevated cholesterol levels.
Here are the best two alternative healthy cooking pans for cooking eggs.
Cast iron skillets: Cast iron cookware is known for its durability and even heat distribution. When properly seasoned and maintained, it becomes naturally non-stick without the health risks associated with synthetic non-stick coatings. It's important to remember a few key tips when using cast iron or any cookware: never overheat an empty pan, avoid high temperatures for cooking, and refrain from using metal or abrasive utensils that can damage the cooking surface.
Ceramic cookware: While cast iron is nice, ceramic cookware is a better choice for cooking eggs. Ceramic is non-toxic like cast iron but it has a more even heat distribution and it’s naturally non-stick with the right amount of oil or butter. We use the Always Pan 2.0 from Our Place which is versatile (we use it for everything from eggs to salmon, to chicken) and has over 34,000 reviews averaging 4.6 stars.
The bottom line: Use ceramic cookware (my favorite) or cast iron while avoiding classic non-stick surfaces that contain harmful chemicals.

How Cooking Affects Eggs Nutritional Value
Cooking eggs for extended periods or over high heat can lead to the degradation of essential nutrients and compromise the overall nutritional quality of the dish. Eggs are a rich source of various vitamins and minerals, including B vitamins like riboflavin and folate, which are vulnerable to heat. Prolonged or high-temperature cooking can cause these vitamins to break down, reducing their availability and nutritional benefits. Additionally, egg yolks contain a vital antioxidant called lutein, which plays a role in eye health. Overcooking eggs can diminish lutein levels, potentially depriving your body of this important compound.
Furthermore, when eggs are subjected to excessive heat, their protein structure can be altered. This can result in the formation of compounds like acrylamide, which has been associated with health concerns. Overcooking eggs can also lead to the development of a greenish-gray ring around the yolk, indicating sulfur and iron compounds reacting at high temperatures. While these compounds are not necessarily harmful, they can negatively affect the texture and flavor of the eggs. Therefore, it's essential to strike a balance between thorough cooking to ensure food safety and avoiding excessive heat or prolonged cooking times to preserve the nutritional value and overall quality of your eggs.
The bottom line: Cook eggs low and slow and not too long.
5 Healthy Ways To Cook Eggs
Sunny-Side Up: Preheat a ceramic frying pan over low to medium heat. Add a small amount of avocado oil or a pat of butter. Crack the eggs into the pan and cook them slowly until the whites are set but the yolks remain runny.
Scrambled Eggs: Heat a cast iron skillet on low heat, and add a bit of avocado oil or butter. In a bowl, whisk the eggs with a pinch of salt and pepper. Pour the beaten eggs into the skillet and gently stir them as they cook over low heat. Remove from heat just before they're fully set, as they'll continue to cook from residual heat.
Poached Eggs: Bring a pot of water to a gentle simmer and add a splash of vinegar. Crack an egg into a small bowl. Create a gentle whirlpool in the simmering water and carefully slide the egg into the center. Cook for about 3-4 minutes until the whites are set. Remove with a slotted spoon. Poaching preserves the nutrients and doesn't require added fats.
Soft-Boiled Eggs: Place eggs in a saucepan and cover them with cold water. Bring the water to a boil, then immediately reduce the heat to a gentle simmer. Simmer for 4-5 minutes for soft-boiled eggs. Run them under cold water to stop cooking. Soft-boiled eggs maintain their nutrients as they are not exposed to high temperatures.
Microwave Magic: If you're in a hurry, you can use the microwave to cook eggs quickly while retaining their nutritional value. Using a glass bowl, whisk together butter and an egg or two. Cover with a microwave-safe lid or plate and cook on medium power for about 30 seconds. Remove, stir, then put it in for another 15-30 seconds. Enjoy.
Takeaway
When it comes to choosing the healthiest eggs, opt for pasture-raised and organic varieties for a boost in nutrients and a commitment to ethical farming practices. Avoid conventional eggs from caged chickens, which may contain pesticide residues and antibiotics. In terms of cooking fats, elevate your egg dishes by using butter or avocado oil for the essential fatty acids while steering clear of seed oils like margarine, which have been linked to various health issues.
Your choice of cookware matters for both health and ease of cleaning. Consider ceramic cookware for its even heat distribution and natural non-stick properties, or go for the durability of cast iron skillets. These options outshine traditional non-stick surfaces that can release harmful toxins when exposed to high temperatures. Lastly, remember that cooking eggs gently and not for too long is key to preserving their nutritional value, as extended cooking times and high heat can degrade essential vitamins and proteins. Enjoy the benefits of eggs while making mindful choices in their preparation.
