Olive Oil Instead of Vegetable Oil?

Understanding their origins, types, and primary characteristics can elevate your culinary game, so let’s talk about the basics of both oils.

Olive Oil

Origin and Extraction

Olive oil comes from the humble olive fruit. To me, it’s intriguing how such a small fruit yields an oil with immense flavor and versatility. 

The extraction process involves crushing olives and separating the oil from the pulp. Depending on the method used, you get different grades of olive oil.


  • Extra Virgin Olive Oil (EVOO): The top-quality stuff. It’s made from the first pressing of olives, has a distinct taste, and is perfect for drizzling over salads or dipping bread. It can be filtered or unfiltered (the latter tends to have a stronger taste due to the presence of olive particles).
  • Virgin Olive Oil: Similar to EVOO but has a slightly less intense flavor. Still great for cooking, especially when you want that olive essence without overpowering the dish.
  • Refined Olive Oil: Processed to remove any imperfections. It’s milder in flavor, making it suitable for cooking methods like frying, where EVOO might be too robust.

Key Characteristics

  • Flavor: Ranges from fruity to peppery, depending on its type and the olives used.
  • Color: Typically a golden green, but can vary based on type and region.
  • Smoking Point: Varies, with refined olive oil having a higher smoke point suitable for frying, while EVOO is best reserved for low to medium heat.

Vegetable Oil

The term “vegetable oil” can be slightly misleading. While many assume it’s derived from a blend of vegetables, it often refers to oils extracted from seeds like soybean, sunflower, or corn.

Key Characteristics

  • Flavor: Neutral, which is why it’s a favorite in baking or dishes where you don’t want the oil to dominate.
  • Color: Light yellow to clear.
  • Smoking Point: Generally high, making it a popular choice for frying and high-heat cooking.

By acquainting ourselves with the fundamental aspects of these oils, we’re better equipped to make decisions in the kitchen. But, as always, the devil is in the details, which we’ll explore in the following sections.

Types and Sources 

While the umbrella term “vegetable oil” may give an impression of a singular entity, in reality, it represents a diverse group of oils derived from various plants. Their properties can vary depending on the source:

  • Soybean Oil: Extracted from soybeans, this oil is most commonly used in the United States. Its mild flavor and high smoke point make it versatile for frying and sautéing.
  • Sunflower Oil: Derived from sunflower seeds, it’s known for its light taste and frying suitability. Plus, its rich Vitamin E content is a bonus.
  • Corn Oil: Extracted from the germ of corn kernels, this oil has a neutral flavor and is often used in frying due to its high smoke point.
  • Canola Oil: Originally developed from rapeseeds, canola oil has become a staple in many kitchens because of its heart-healthy profile and neutral taste, making it fit for cooking and baking.


Most vegetable oils are refined to remove impurities, increase shelf life, and stabilize the flavor. The refining often includes steps such as bleaching and deodorizing.

Health and Nutritional Aspects

  • Fats: Predominantly composed of polyunsaturated and monounsaturated fats, considered heart-healthy options.
  • Vitamin E: Many vegetable oils are a good source of Vitamin E, an antioxidant that supports skin health and helps protect cells from damage.
  • Omega Fatty Acids: Oils like soybean and canola are known for their omega-3 and omega-6 content, essential fats our body doesn’t produce on its own.

My Recommendation

Having cooked with both olive oil and a variety of vegetable oils over the years, I’ve recognized that if you’re aiming for a Mediterranean touch or want to add a rich, fruity note, olive oil, particularly EVOO, is unbeatable. Its depth and aroma can elevate simple dishes to gourmet levels.

On the other hand, when it comes to general cooking, especially frying or when I don’t want the oil’s flavor to stand out, I gravitate towards vegetable oils. Their neutral taste ensures they don’t overshadow other ingredients. Soybean and canola oils have been my go-to because of their balanced nutritional profile and versatility.

That said, my recommendation? Stock your kitchen with both!

Use olive oil when its unique characteristics can shine, and employ vegetable oil for broader applications. By doing so, you ensure you’re equipped for any culinary challenge that comes your way.


Olive oil vs Vegetable oil

Vegetable Oil vs. Olive Oil Differences: 

Understanding the differences between olive and vegetable oils is more than just knowing their sources. Here’s what stands out:

Flavor Profiles

  • Olive Oil: It’s a symphony of flavors, ranging from grassy to fruity and sometimes even peppery, especially in the case of EVOO. Such distinct flavors are often sought in salads, pasta, and Mediterranean dishes.
  • Vegetable Oil: Their allure lies in subtlety. With a neutral profile, they don’t interfere with or mask the flavors of other ingredients, making them a top choice for baking and dishes with nuanced flavors.

Cooking Temperatures and Stability

  • Olive Oil: It generally has a lower smoke point, especially EVOO. This makes it ideal for light sautéing, drizzling, or dressings. Using it at high temperatures can result in a bitter taste and potential health concerns.
  • Vegetable Oil: Thanks to its high smoke point, vegetable oil champions frying, deep frying, and high-heat sautéing. It remains stable, ensuring the dish’s flavors stay intact.

Nutritional Value

  • Olive Oil: Packed with monounsaturated fats and antioxidants, it’s often lauded for its potential heart health benefits. Plus, polyphenols, especially in EVOO, might offer additional health advantages.
  • Vegetable Oil: Generally rich in polyunsaturated fats, essential for our body. However, it’s worth noting that some, like sunflower oil, can have a higher omega-6 to omega-3 ratio, a point of consideration for some health-conscious individuals.

Culinary Applications

Olive oil, with its health benefits, high smoke point, and flavor-enhancing qualities, is an excellent choice for baking, sautéing, stir-frying, salad dressings, or marinades. It adds a fruity and zesty flavor to the dish.


Olive oil can be used in baking, but it’s crucial to consider its flavor profile and choose a mild or neutral-flavored oil for best results. Here are my tips for using olive oil in baking:

  • Use a 1:1 substitution ratio when replacing vegetable oil with olive oil in baking recipes.
  • Consider the health advantages of olive oil, such as its higher monounsaturated fat content and antioxidant properties.
  • Using olive oil in baking can produce lighter and more moist baked goods.

Some examples of baked goods that can benefit from olive oil include olive oil cake, known for its moist and tender texture. 

When substituting olive oil in baking recipes, be mindful of the oil’s flavor profile and adjust the recipe as needed to ensure a balanced and delicious result.

Sautéing and Stir-Frying

I recommended regular olive oil for these cooking methods. Extra virgin olive oil isn’t suitable for high-temperature cooking due to its lower smoke point (and higher cost).

When sautéing and stir-frying with olive oil, be mindful of its smoke point and adjust the heat accordingly to prevent the oil from breaking down and releasing potentially hazardous compounds. 

Salad Dressings and Marinades

Extra virgin olive oil is particularly suitable for most salad dressings, as it adds a flavorful element to the recipe. When using olive oil in salad dressings and marinades, it’s crucial to select the appropriate olive oil for the dish and modify recipes accordingly.

It’s also a good idea to mix the two oils. A mix of olive and vegetable oil can create a balanced marinade, combining the robustness of olive oil with the subtlety of vegetable oil.


For dishes that require both flavor and high heat, combining the oils can be a solution, too. It ensures the dish gets the earthy notes of olive oil while benefiting from the stability of vegetable oil.

Potential Pitfalls and How to Avoid Them

Navigating the world of oils can sometimes feel like a tightrope walk. One misstep and your dish could be a culinary disaster. What are the most common pitfalls then? 

Overwhelming a Dish with Olive Flavor

  • Finding Balance: The robust nature of olive oil, particularly extra virgin variants, can dominate other flavors if not used judiciously. Start with a smaller quantity and adjust according to taste. Remember, you can always add more, but you can’t take it away once mixed in.
  • Mixing Oils: If you’re hesitant about the overpowering taste of olive oil, consider blending it with a milder oil. This technique not only balances out the strong flavor but also offers a more versatile cooking medium, especially for high-heat dishes.

Not Accounting for Smoke Points

  • The Risk: Every oil has a specific temperature, known as the smoke point, beyond which it begins to smoke and break down. This not only impairs the taste but can also release harmful compounds.
  • Stay Informed: Knowing the smoke points of the oils you’re working with is essential. While olive oil, especially EVOO, has a lower smoke point and is ideal for light sautéing or drizzling, most vegetable oils can withstand higher temperatures, making them suitable for frying or roasting.

Improper Storage

  • The Threat: Oils are susceptible to degradation from light, heat, and air. If not stored properly, they can become rancid, affecting taste and nutritional value.
  • Storage Tips:
    • Dark & Cool: Store your oils in a cool, dark place, away from direct sunlight and heat sources.
    • Tightly Sealed: Ensure the bottles are tightly closed after every use to prevent air from getting in.
    • Clear Bottles: If your oil comes in a clear bottle, consider transferring it to a darker one or wrapping it to shield it from light.

Bottom Line

So, can you use olive oil instead of vegetable oil? Yes, you absolutely can. However, the decision hinges on your culinary goals, from flavor nuances to cooking techniques. 

While both oils boast distinct advantages, understanding their characteristics ensures optimal results in the kitchen. 

Choose wisely based on your dish, and you’ll rarely go wrong.
