Yes, avocado oil can be used instead of vegetable oil in cooking and baking. It is a versatile, neutral-flavored oil with a high smoke point, making it suitable for sautéing, frying, baking, and even dressings or marinades. Avocado oil can generally be substituted in a 1:1 ratio for vegetable oil in recipes. It has additional health benefits compared to many vegetable oils, as it is rich in healthy monounsaturated fats and antioxidants, and it may help reduce cholesterol and inflammation. The main downside is that avocado oil tends to be more expensive than generic vegetable oil.
