The Core Calorie Count: The Egg Itself
Before you crack an egg into a hot pan, the primary calorie count comes from the egg itself. An egg's calorie content is directly related to its size, with most of the energy coming from the yolk.
Egg Calories by Size
- Small Egg (38g): ~54 calories
- Medium Egg (44g): ~63 calories
- Large Egg (50g): ~72 calories
- Extra-Large Egg (56g): ~80 calories
- Jumbo Egg (63g): ~90 calories
As you can see, a standard large egg contains about 72 calories before any cooking method is applied. The yolk, which constitutes about one-third of the egg's weight, holds the majority of the calories and fat, while the egg white is mostly protein with very few calories.
How Cooking Method Impacts Calories
The sunny side up style involves frying an egg in a pan, which means adding a fat like butter or oil. This is the main difference between a plain egg and a sunny side up egg from a calorie perspective. Unlike poached or boiled eggs, which have no added fat, frying can increase the final calorie count by a notable amount. The amount of extra calories depends entirely on the type and quantity of fat used.
The Calorie Factor of Added Fats
Any fat you use to fry an egg will add calories. A single tablespoon of oil contains around 120 calories, and while you may not absorb all of it, a significant portion will be incorporated into the finished dish.
- Butter: One tablespoon of butter adds approximately 102 calories.
- Olive Oil: A tablespoon of olive oil contains roughly 120 calories.
- Cooking Spray: Using a non-stick cooking spray is the lowest-calorie option, adding just 1-2 calories per spray.
A Complete Breakdown of Sunny Side Up Calories
Combining the base calorie count of the egg with the added cooking fat gives you the total for your meal. For a large egg, this can look like the following:
- Large Egg (72 kcal) + 1 tsp Olive Oil (~40 kcal) = ~112 calories
- Large Egg (72 kcal) + 1 tbsp Butter (~102 kcal) = ~174 calories
- Large Egg (72 kcal) + 2 sprays Cooking Spray (~2 kcal) = ~74 calories
Based on these calculations, a typical sunny side up egg cooked with a standard amount of oil or butter will contain somewhere between 90 and 120 calories, aligning with common nutritional data. However, this is a highly variable number based on your cooking habits.
Comparison of Egg Cooking Methods
To illustrate the difference in calorie counts, consider this comparison table for a large egg prepared in various ways:
| Cooking Method | Estimated Calories | Total Fat (g) | Protein (g) | Key Difference |
|---|---|---|---|---|
| Sunny Side Up (fried in minimal oil) | ~90-100 kcal | ~6.8 g | ~6.3 g | Added fat increases calories and fat content. |
| Boiled | ~78 kcal | ~5 g | ~6 g | No added fat, maintaining the egg's natural nutrient profile. |
| Poached | ~71 kcal | ~4 g | ~6 g | Cooked in water, resulting in the lowest calorie count. |
| Scrambled (with butter & milk) | ~100+ kcal | Varies greatly | Varies | Cream and butter add significant fat and calories. |
Tips for a Healthier Sunny Side Up
There are simple ways to keep your fried egg dish a healthy addition to your diet.
- Use a Non-Stick Pan: This allows you to use minimal or no oil, significantly cutting down on extra calories.
- Choose a Healthy Oil: If you must use oil, opt for a heart-healthy option like olive or avocado oil, and use only a small amount.
- Use Cooking Spray: For the absolute lowest-calorie method, use a non-stick cooking spray instead of oil or butter.
- Blot Excess Oil: After frying, you can place the egg on a paper towel for a few seconds to absorb any extra residual oil.
- Limit Pairings: Be mindful of what you serve with your eggs. High-calorie pairings like cheese, bacon, and heavy sauces can add far more calories than the egg itself.
Beyond Calories: Nutritional Benefits
Beyond the calorie count, eggs are a nutritional powerhouse. They are packed with high-quality protein, which aids in satiety and muscle repair. Eggs also contain essential vitamins and minerals.
- Vitamins: Rich in Vitamins A, D, B2, B6, and B12.
- Minerals: A good source of iron, selenium, and phosphorus.
- Choline: A crucial nutrient for brain and nerve function.
- Antioxidants: Contains lutein and zeaxanthin, which are beneficial for eye health.

The Final Takeaway on Sunny Side Up Calories
So, how many calories are in one sunny side up egg? The answer depends on your preparation. For a large egg, the base is around 72 calories, but this typically increases to between 90 and 120 calories with added cooking fat. By being mindful of the type and amount of oil or butter you use, you can enjoy a delicious and nutrient-dense sunny side up egg as part of a healthy diet.
