Plus, the best part is that eggs are a nourishing option at any meal—whether for breakfast, lunch, or dinner. However, achieving the perfect texture without ending up with a tough, rubbery egg can be tricky. Also, the choice of cooking method plays a significant role in the healthfulness of the dish, as certain techniques may add extra ingredients or alter nutritional benefits. Here, we will break down the most popular egg-cooking methods and rank them in terms of health benefits and ease of preparation. Keep reading to discover the healthiest way to cook an egg.
The Health Benefits of Eggs
For many years, eggs have sparked debate among health professionals due to the cholesterol and saturated fat in their yolks. The research on these fats remains divided. Some studies suggest a link between saturated fat and cholesterol and an increased risk of heart disease due to elevated blood cholesterol levels, while others have found no clear connection. “However, recent studies indicate that, for the majority of people, cholesterol from eggs has little to no impact on blood cholesterol. In fact, research has shown that consuming eggs regularly has minimal effects on heart disease risk for most individuals,” says Soares.
Eggs are packed with a wide range of valuable nutrients, such as selenium, phosphorus, choline, iron, vitamin A, and B vitamins like riboflavin, pantothenic acid, and folate. Together, these nutrients promote immune, bone, brain, eye, blood, and metabolic health. “One large egg provides about six to seven grams of protein, aiding in muscle growth, tissue repair, and immune function,” adds Soares. Eggs also contain carotenoids like lutein and zeaxanthin, which are known to support eye health and protect against cataracts and age-related macular degeneration. Given that eggs provide these beneficial nutrients while also containing notable amounts of dietary cholesterol and saturated fat, it’s best to consume them in moderation. This approach is especially important for those at risk for heart-related issues.
The Healthiest Ways to Cook Eggs
When we choose to eat eggs, there are certain cooking methods we can use to maximize their nutritional value. Let’s explore the health impacts of various egg-cooking techniques.
Scrambled Eggs
For individuals with a hectic routine, scrambling eggs provides a fast and simple solution. Typically, scrambled eggs are made with butter or oil, and often a nonstick pan is used. However, butter is high in dietary cholesterol and saturated fat, while nonstick pans have been criticized for potentially releasing harmful substances like per- and polyfluoroalkyl chemicals (PFAS), also known as forever chemicals. “To make scrambled eggs more heart-healthy, opt for a cook-safe nonstick pan (or stainless steel) and use minimal oil or butter, or choose healthier oils like olive oil,” recommends Soares.
Boiled Eggs
Hard-boiled eggs are a convenient, portable snack and can easily be prepared in advance, making them one of the healthiest ways to cook eggs. “Boiled eggs tend to be more filling because their 55 percent water content doesn't evaporate during cooking, unlike in other methods like scrambling,” says Soares. Additionally, boiling eggs doesn't require any extra oils.
Poached Eggs
Mastering the art of poaching an egg is no small feat. Poaching involves gently cooking a cracked egg in simmering water until the whites are set and the yolk remains runny. In my own experience, it can be tricky to keep the egg intact without separation. “A helpful tip for flawless poaching is to add a small amount of vinegar to the water, which helps the egg white stay together, resulting in a perfect, restaurant-worthy egg,” suggests Soares. Poached eggs are also an excellent health option because they require no fats, making them low-calorie and free from extra cholesterol and saturated fats. “Moreover, since poaching uses lower temperatures, there’s a reduced risk of forming cholesterol oxidation products that are common in methods like frying,” Soares adds.
Fried Eggs
Many people have fond memories of gathering around the breakfast table to enjoy a plate of fried eggs during their childhood. While frying eggs can be quite flavorful, using excessive oil or butter can make them especially high in fat,” explains Soares. To reduce these effects, consider using healthier fats like avocado or olive oil, and cook on low heat to avoid burning. This prevents the formation of harmful compounds like acrylamide, which has been linked to increased cancer risk, according to the American Cancer Society.
Baked Eggs
Though not as commonly chosen as other methods, baked eggs are a simple and healthy way to enjoy this versatile food. Whether you’re preparing a casserole, frittata, shakshuka, or eggs in purgatory, pairing baked eggs with vegetables or whole grains can boost their health benefits. However, similar to scrambled eggs, it's essential to be mindful of added fats and high-calorie ingredients like cheese,” advises Soares.
Tips for Cooking the Healthiest Eggs
To get the most health benefits from eggs, there are several important tips to follow.
- Temperature regulation: “Cooking eggs at lower temperatures helps maintain their nutrients and prevents the formation of potentially harmful substances, such as cholesterol oxidation products and acrylamide, which are produced when eggs are cooked too long at high temperatures,” explains Soares.
- Opt for healthy fats: Choose heart-friendly fats like olive oil, avocado oil, and ghee to reduce saturated fat and cholesterol intake. Additionally, avoid excessive salt consumption, as long-term high salt intake can lead to high blood pressure.
- Incorporate healthy ingredients: Pair your eggs with nutrient-rich additions such as vegetables, herbs, lean proteins, and spices like turmeric or pepper to enhance flavor, antioxidants, and overall health,” suggests Soares.
The Winners
Based on the information provided, some cooking methods are highlighted as the healthiest ways to prepare eggs. As Soares explains, “Boiling and poaching stand out as the best methods because they are simple and preserve nutrients.” While these methods result in different textures, both involve cooking eggs in water. Using water instead of butter or oil helps cut down on calories, saturated fats, and cholesterol. Additionally, both techniques use lower heat than frying or scrambling, which helps reduce the risk of forming harmful compounds.
Although boiled and poached eggs are considered the healthiest methods, you can still enjoy other techniques like scrambling, baking, and frying, as long as you make mindful changes, such as the tips mentioned earlier.
