How Much Protein in an Ostrich Egg

Ostrich eggs are one of the largest edible eggs in the world, yet most people in the UK have never had the opportunity to eat one. Despite their rarity in the average British kitchen, ostrich eggs are a fascinating food item with an impressive nutritional profile, especially when it comes to protein. With the rise in interest in alternative protein sources, from insects to plant-based powders, ostrich eggs have occasionally been spotlighted as a novelty and a nutrient-rich food worth exploring.

This article will explain how much protein is in an ostrich egg, how it compares to chicken eggs and other sources of protein, and how it fits into a healthy diet. We will also explore how ostrich eggs are prepared, their other nutritional qualities, any risks or downsides, and whether they are a sustainable option.

How Much Protein Is in an Ostrich Egg?

An average ostrich egg weighs about 1.2 to 1.4 kilograms. This is roughly the size of 20 to 24 chicken eggs. In terms of protein, one whole ostrich egg provides approximately 115 grams of protein. This protein is spread between the yolk and the egg white, much like in a chicken egg, but on a much larger scale.

The egg white is particularly rich in protein, contributing about two-thirds of the total protein content. The yolk, while also offering some protein, contains a higher proportion of fat and cholesterol. So, although an ostrich egg is large, it still mirrors the basic structure of a standard egg, just in a supersized version.

Ostrich Eggs vs Chicken Eggs: The Protein Comparison

A single medium chicken egg contains about 6 grams of protein. By comparison, an ostrich egg offers about 115 grams in total. When you divide that across its volume, it equates to around 9 to 10 grams of protein per 100g of raw egg, which is slightly less concentrated than a chicken egg.

This difference is likely due to the higher water content in ostrich eggs, which slightly dilutes the macronutrient concentration. However, in practical terms, one ostrich egg could meet the daily protein requirements of an average adult for two full days.

How Bioavailable Is the Protein in Ostrich Eggs?

The protein in ostrich eggs is considered complete, meaning it includes all nine essential amino acids required by the human body. These amino acids support muscle maintenance, tissue repair, hormone production, and immune function. Just like chicken eggs, the protein found in ostrich eggs is highly bioavailable, meaning it is easy for the body to absorb and utilise.

Ostrich egg protein has not been studied as extensively as chicken egg protein, but what research exists confirms its suitability as a quality dietary protein source. Egg protein is often used as a reference point in assessing other proteins, due to its high digestibility and amino acid profile. This puts ostrich eggs in good company and makes them a valuable addition to any high-protein diet, if available.

What Does an Ostrich Egg Taste Like?

The taste of an ostrich egg is similar to that of a chicken egg, but slightly richer and more buttery. The yolk has a thicker texture and more intense flavour, while the white is milder and slightly gelatinous. When cooked, the texture is softer and less rubbery than chicken eggs, although this can vary based on how it is prepared.

Due to their large size, ostrich eggs are typically scrambled or made into large omelettes when cooked. They can take over an hour to hard boil and even longer to bake. The novelty of cooking with an ostrich egg is part of the appeal, but it also presents some challenges for everyday meals.

Other Nutrients in Ostrich Eggs

Ostrich eggs are not just a source of protein. They are also rich in other important nutrients. A single ostrich egg contains high levels of vitamin B12, riboflavin (B2), folate, selenium, and iron. These nutrients support red blood cell production, nervous system health, immune defence and energy metabolism.

Like chicken eggs, ostrich eggs also contain cholesterol and fat, particularly in the yolk. While dietary cholesterol is no longer considered a major issue for most people, those with specific heart or metabolic conditions may want to moderate intake. The fat content in one ostrich egg is approximately 100 grams, most of which is unsaturated, although there is still a notable amount of saturated fat.

How Ostrich Eggs Fit into a Balanced Diet

Ostrich eggs can provide a substantial amount of protein and essential nutrients in a single serving. However, due to their size and the practicalities of storage and preparation, they are not typically consumed as part of a daily diet. In the UK, they are usually sold in specialist shops, farm stores, or online, often as a luxury or novelty item.

For individuals looking to increase their protein intake through whole foods, ostrich eggs can be a fascinating and effective option, especially for families or groups who wish to share one across multiple meals. The protein is complete, well-absorbed and paired with beneficial micronutrients, making it a strong contender nutritionally.

However, ostrich eggs are not a substitute for regular lean protein foods such as fish, poultry, beans, or dairy. Instead, they offer variety and interest, and their high protein content makes them a suitable occasional inclusion.

How to Cook and Use an Ostrich Egg

Cooking an ostrich egg requires patience and preparation. The shell is thick and often needs a drill or hammer to open. Once cracked, the egg can be scrambled, fried in sections, or used in baking.

For a comparison, one ostrich egg could make an extra-large frittata to feed 10 or more people. It can also be used in baking cakes, pancakes, or muffins where several chicken eggs would normally be used. The rich flavour of the yolk works well in savoury dishes, while the protein-rich white can be whipped into meringue or added to protein-focused recipes.

When storing leftovers, cooked ostrich egg can be refrigerated for a few days. It should be treated similarly to cooked chicken egg in terms of hygiene and shelf life.

Protein and Satiety: Can an Ostrich Egg Keep You Full?

Protein-rich foods are known to increase satiety, helping people feel full for longer and reducing the likelihood of overeating. Ostrich eggs, with their substantial protein content, are no exception. Eating meals based on eggs has been shown to reduce appetite compared to those based on refined carbohydrates, particularly in the morning.

An ostrich egg meal may provide long-lasting energy and fullness, especially when paired with fibre-rich vegetables or wholegrains. This makes it a valuable food choice for those managing their weight or trying to balance hunger and energy across the day.

However, due to the high fat content, particularly in the yolk, portion control still matters. Eating too much fat at once can lead to excessive calorie intake and may not suit everyone’s digestive tolerance.

Can Ostrich Eggs Replace Meat as a Protein Source?

In theory, yes. One ostrich egg offers as much protein as a generous portion of red meat or poultry, making it an alternative for those who wish to reduce meat consumption. However, the availability and cost of ostrich eggs make them a less convenient replacement for most households.

From a sustainability perspective, ostrich farming produces lower greenhouse gas emissions than cattle farming. Ostriches also require less water and feed, and their eggs are more efficient in terms of energy and protein yield per square metre of land. That said, the infrastructure for widespread ostrich egg consumption in the UK is limited, so this substitution remains niche.

For vegetarians who eat eggs, ostrich eggs can still contribute meaningfully to protein intake without needing to rely on meat or fish. They also offer a way to add diversity to an otherwise repetitive egg-based diet.

Allergies, Intolerances, and Safety Considerations

Those with egg allergies should avoid ostrich eggs, as they contain many of the same proteins that trigger allergic reactions in chicken egg-sensitive individuals. While some people with chicken egg allergy can tolerate duck or quail eggs, ostrich eggs are not typically considered hypoallergenic.

There is also a small risk of contamination with Salmonella, especially if the egg is consumed raw or undercooked. This is similar to the risk posed by chicken eggs before the widespread adoption of the British Lion Quality mark. As a precaution, ostrich eggs should always be fully cooked unless pasteurised.

People with high cholesterol or cardiovascular conditions should consult with a healthcare provider before making ostrich eggs a regular feature in their diet, especially if consuming the yolk in large quantities.

How Much Protein Do You Need Per Day?

In the UK, the Reference Nutrient Intake (RNI) for protein is 0.75 grams per kilogram of body weight per day. This works out to around 50g for the average adult. Active individuals, older adults and those recovering from illness may need more.

A single ostrich egg provides more than double the RNI for protein, making it an efficient way to meet daily requirements. However, due to the other nutrients and energy density, it should not be relied upon as the sole source of protein in a varied diet.

Can Ostrich Eggs Be Used with Protein Powder?

Yes, in fact the two can complement each other quite well. While ostrich eggs offer high-quality complete protein from a whole food source, protein powders provide a quick, low-fat and often lactose-free option for topping up daily intake. For individuals who have tried ostrich eggs and want a more accessible and affordable option for daily use, protein powder is an excellent supplement.

Combining whole foods like ostrich egg with shakes, smoothies, or recipes using protein powder can help you hit personal nutrition targets, especially if you have high needs due to sport, age, or health conditions.

Conclusion

Ostrich eggs are a powerhouse of complete protein, providing roughly 115 grams per egg. That makes them one of the most protein-rich natural foods available, albeit in a form that is more suited to special occasions or shared meals. They contain all essential amino acids, along with a range of vitamins and minerals that support whole-body health.

While they are not part of the everyday UK diet, ostrich eggs offer variety, novelty and excellent nutritional value. Their protein content rivals or surpasses many standard meat and egg options, making them worth exploring for those curious about food diversity and high-protein alternatives.
