Technically, yes, you can swap olive oil for vegetable oil in a 1:1 ratio by volume. But that’s a bit like saying you can swap a house cat for a tiger because they’re both felines. The math is easy; the flavor is not. If your recipe calls for 1 cup of vegetable oil, use 1 cup of mild olive oil. But—and this is a big but—if you’re using extra-virgin, reduce the amount by a tablespoon or two. Olive oil tastes stronger, and you don’t want your cake to taste like an olive orchard.

Also, think about texture. Olive oil is heavier and can make certain baked goods denser. If you’re making a light, fluffy angel food cake, stick with the neutral stuff. If you’re making a moist, rustic loaf, olive oil is your best friend.
The Smoke Point Trap (Don’t Get Caught)
Here’s the dreaded side comment: That smoke point isn’t just a suggestion; it’s a chemical line in the sand. When olive oil (especially EVOO) gets too hot, it breaks down and releases acrolein, a compound that smells like burnt plastic and tastes like regret. Plus, it destroys the precious antioxidants that make olive oil healthy. So if your recipe involves high heat—stir-frying, roasting at 425°F or above—please, just reach for the vegetable oil or avocado oil. Your lungs and your taste buds will thank you.
For roasting veggies? You’re safe with olive oil at 375°F or lower. Drizzle those carrots with confidence. But if you’re blasting them at 450°F? Use the neutral oil. I know, I know—it feels less Italian and sophisticated. But you’ll get crispy results without the smoke.
