Understanding Cooking Fats
Key factors beyond just the calorie count
Calorie Density
All pure fats are calorie-dense (around 9 kcal per gram). The calorie difference between butter and oil per tablespoon is minimal (roughly 15-20 kcal).
Saturated vs. Unsaturated
Butter is high in saturated fat, which can raise LDL cholesterol. Most plant oils are rich in heart-healthy monounsaturated and polyunsaturated fats.
Smoke Point Matters
Butter burns easily (smoke point ~175°C/350°F). Oils like avocado (~270°C/520°F) and refined olive oil (~240°C/465°F) are much safer for high-heat cooking.
Flavour & Texture
Butter provides unmatched flavour and flakiness in pastries. Oil provides moisture and tenderness in cakes and quick breads. Choose based on the desired culinary outcome.

Cooking Fats FAQ
Answers to the most frequently asked questions about butter, oil, and nutritional substitutions.
Most liquid cooking oils (like olive, canola, and avocado oil) have slightly more calories per tablespoon (around 119-124 kcal) compared to butter (around 102 kcal per tablespoon). However, oils contain significantly less saturated fat, which is often the more important metric for heart health.
For everyday cooking, unsaturated oils like olive oil or avocado oil are generally considered healthier than butter due to their lower saturated fat content and presence of heart-healthy monounsaturated fats. Butter can be enjoyed in moderation, especially for flavour in baking or finishing dishes.
Yes, you can often substitute oil for butter in baking at a 3:4 ratio (e.g., 3 tablespoons of oil for every 4 tablespoons of butter). This can result in a moister texture, though it may slightly alter the flavour and structure of the final product, particularly in pastries that rely on butter for flakiness.
Extra virgin olive oil is widely considered the healthiest substitute for butter due to its high monounsaturated fat content, antioxidants, and proven cardiovascular benefits. Avocado oil is another excellent alternative, especially for high-heat cooking where olive oil might burn.
While coconut oil is plant-based, it is exceptionally high in saturated fat (even higher than butter). Major health organisations recommend limiting coconut oil intake. It can be used occasionally for specific flavour profiles, but it is not a heart-healthy daily substitute for butter.
