Yes. Olive oil can replace vegetable oil in many recipes using a 1:1 ratio. If a recipe calls for ½ cup of vegetable oil, you can generally use ½ cup of olive oil.
The main difference is flavor. Extra virgin olive oil contributes its own aroma and taste, while vegetable oil is usually selected for its neutral character.
Can You Substitute Olive Oil for Vegetable Oil?
Yes. For most recipes that call for liquid vegetable oil, use the same quantity of olive oil:
1 cup vegetable oil = 1 cup olive oil
The conversion is simple. The important question is whether you want the flavor of olive oil in the finished dish.
What Is the Difference Between Olive Oil and Vegetable Oil?
Olive oil is obtained from the fruit of the olive tree. Extra virgin olive oil is mechanically extracted without refining and can have fruity, bitter, and peppery characteristics.
Vegetable oil is a broad category of oils obtained from plants. In the United States, a bottle labeled “vegetable oil” is commonly made primarily from refined soybean oil, although it may contain another plant oil. Check the ingredient statement to identify what is inside the bottle.
Most supermarket vegetable oils are refined to produce a mild or neutral flavor. This makes them useful when a recipe should not taste like the oil used to prepare it.

When to Choose Olive Oil Instead of Vegetable Oil
Olive oil can replace vegetable oil in many recipes, but the better choice depends on the cooking method and whether you want the oil to add flavor. Here are five common situations:
-
Salad dressings. Choose extra virgin olive oil when you want fruity, bitter, or peppery flavor. Vegetable oil is more neutral and contributes little flavor of its own.
-
Marinades. Olive oil works well in marinades for meat, fish, and vegetables, particularly when combined with herbs, citrus, garlic, or spices.
-
Sautéing and stir-frying. Olive oil is suitable for many everyday stovetop preparations. Choose it when its flavor complements the other ingredients.
-
Deep-frying. Either oil may be used, depending on the required temperature and desired flavor. Vegetable oil is often selected when neutrality and cost are priorities.
-
Baking. Olive oil works particularly well with chocolate, citrus, nuts, and spices. For delicate baked goods that require a neutral flavor, vegetable oil may be the better choice.
Can You Cook With Olive Oil Instead of Vegetable Oil?
Yes. Olive oil can be used for sautéing, roasting, sauces, marinades, dressings, and many other everyday preparations.
Cooking performance depends on the specific oil, its condition, and the temperature being used. Smoke point is relevant, but it is not the only measure of how an oil performs when heated.
For a dedicated explanation, read our guide to the smoke point of olive oil.
When Should You Not Substitute Olive Oil?
Do not make the substitution automatically when a recipe requires a completely neutral flavor. A distinctive extra virgin olive oil can change the aroma and taste of delicate cakes, frostings, and lightly flavored baked goods.
Vegetable oil may also be the more practical option when a recipe requires a large quantity of inexpensive, neutral oil.
The Bottom Line
Olive oil can replace vegetable oil in many recipes using a 1:1 ratio.
Choose extra virgin olive oil when its flavor will complement the food. Choose vegetable oil when neutrality or cost is the priority.
