Can you substitute olive oil for vegetable when making waffles?

While you can technically substitute olive oil for vegetable oil when making waffles, it may alter the taste and texture of the final product. Olive oil has a distinct flavor that might not complement the flavor of waffles as well as vegetable oil. Additionally, olive oil has a lower smoke point than vegetable oil, so it may burn more easily if your waffle iron is too hot. For best results, stick to using vegetable oil when making waffles.
