Olive Oil vs Vegetable Oil
Plant oils are commonly used in most kitchens; they're used for frying, sautéing, and making sauces, they play a big role in everyday cooking. Olive oil and vegetable oil are the two most widely used types of oils, and each has its own advantages and disadvantages. Let's look at the differences between olive and vegetable oils, mentioning their best uses, tastes, nutritional value, and likely health benefits.
Differences Between Olive Oil and Vegetable Oil
Choosing the correct oil for your recipe can feel hard with so many alternatives on the shelves. You’ve likely wondered, "Should I use olive oil or vegetable oil?" Choosing the right oil for your food might be made easier if you understand how these two different from one another.
What Is Olive Oil?
Olive oil comes from the liquid fat of olives, the fruit of the olive tree. The extraction process involves pressing whole olives to separate the oil from the pulp. Depending on the refining process, olive oil might vary in flavor and quality.
Types of Olive Oil
There are different types of olive oil, each with its own characteristics:
Extra Virgin Olive Oil (EVOO): This is the highest quality olive oil, cold-pressed and unrefined, which means no heat or chemicals were used during extraction. It’s packed with flavor and has a free acidity of 0.8% or less.
Virgin Olive Oil: This is also extracted without heat or chemicals, but has a slightly higher acidity (2% or less) than EVOO.
Refined Olive Oil: This oil is processed with heat, resulting in a more neutral flavor. It’s often labeled as "light" olive oil and has fewer health benefits compared to EVOO.
Nutritional Profile
Monounsaturated fats which are found rich in extra virgin olive oil (EVOO), are known for their heart-healthy benefits. Moreover, it has polyphenols, which are antioxidants that help in shielding your cells from harm. These compounds are more concentrated in extra virgin olive oil because it’s minimally processed.
Cooking Uses
Every kind of olive oil has a great use. The best olive oils to use in dressings, to dip bread in, or to drizzle over salads are extra virgin and virgin. But because they burn easily, they're not ideal for cooking at high temperatures. Because refined olive oil has a higher smoke point, it works better when sautéing or frying.
What Is Vegetable Oil?
Vegetable oil is derived from plant parts like seeds, nuts, or fruits. It’s a blend of various oils such as soybean, canola, sunflower, or peanut oil. The extraction process can be either mechanical or chemical, and the oil is often refined to give it a neutral taste.
Types of Vegetable Oil
Vegetable oils can be:
Unrefined: These oils retain more of their natural flavors and nutrients but have a lower smoke point, which makes them less suitable for high-heat cooking.
Refined: Most vegetable oils are refined, which increases their smoke point, making them ideal for frying, sautéing, and baking.
Nutritional Profile
Monounsaturated and polyunsaturated fats, such as omega-3 and omega-6 fatty acids, are generally high in vegetable oils. When you substitute these fats for saturated fats in your diet, you'll benefit. However, the health benefits can vary depending on the type of oil used in the vegetable oil blend.
Cooking Uses
Because vegetable oil has a greater smoke point than olive oil, it is suitable for high-temperature cooking processes including sautéing, baking, and frying. It has no taste, therefore it won't interfere with the flavor of your food.


Olive Oil or Vegetable Oil
Let’s compare these two oils:
Fatty Acid Composition
Vegetable and olive oils are both high in unsaturated fats and low in saturated fats. Richer in monounsaturated fats, which are excellent for heart health, is olive oil, especially extra virgin olive oil (EVOO). Vegetable oil's composition depends on the kind of plant it comes from; for example, canola oil has a high monounsaturated fat content, whereas corn oil has a larger polyunsaturated fat content.
Heat Stability
The temperature at which vegetable and olive oils start breaking down and produce harmful compounds is known as their smoke point. Generally speaking, vegetable oil has a higher smoke point, making it better for sautéing and frying. Olive oil, especially extra virgin, has a lower smoke point and is better suited for raw or low-heat cooking.
Flavor Profiles
Olive oil has a distinct earthy, sometimes fruity flavor, especially in its extra virgin form. In contrast, vegetable oil is neutral and won’t alter the taste of your food. So, if you’re looking to add flavor, olive oil is the way to go; if you want something neutral, choose vegetable oil.
Choosing the Right Oil for Different Cooking Methods
The oil you choose should match your cooking method and flavor preference:
High-Heat Cooking: Vegetable oil is your best option for frying and sautéing. If you prefer olive oil, go for refined olive oil since it has a higher smoke point.
Medium-Heat Cooking: Both olive oil and vegetable oil can be used for roasting. Olive oil will add a bit of flavor, while vegetable oil will keep things neutral.
Low-Heat Cooking: Use extra virgin olive oil for salad dressings, dips, or drizzling. Its flavor really shines in raw dishes.


Can I Use Olive Oil Instead of Vegetable Oil?
You might wonder if you can swap olive oil for vegetable oil in your recipes. Here’s a quick guide:
Salad Dressings: Absolutely! Olive oil is a great option for salad dressings, especially extra virgin.
Marinades: Yes, olive oil works well in marinades and will add a nice flavor.
Sautéing & Stir-Fries: Definitely! Olive oil is one of the healthier choices for sautéing and stir-frying, but avoid using extra virgin olive oil for high-heat cooking.
Baking: Maybe. While olive oil can be used in some baking recipes, its strong flavor might not be suitable for all baked goods. Stick to vegetable oil or use a milder olive oil if needed.
Deep-Frying: No. Vegetable oil is better for deep-frying due to its neutral flavor and higher smoke point.
Vegetable Oil Substitutes
If you don’t have vegetable oil on hand, you can easily substitute with:
Olive oil
Walnut oil
Flaxseed oil
Avocado oil
Grapeseed oil
Sesame oil
Coconut oil
What Is Olive Oil Smoke Point?
The temperature at which oil begins to smoke and degrade is known as the smoke point. Regular olive oil can reach 470°F in smoke point, however extra virgin olive oil only reaches 350–430°F. It's essential to stop cooking and remove oil when it begins to smoke in order to avoid harmful compounds.
Whether using vegetable or olive oil, you can improve your cooking and make smarter choices by knowing these important differences.
