There is no definitive answer to this question since there are a lot of factors to consider. However, olive oil is generally considered to be a healthy option for cooking chicken. It is high in monounsaturated fats, which have been shown to be beneficial for heart health. Additionally, olive oil has a relatively low smoke point, meaning that it won't produce harmful chemicals when heated at high temperatures. Ultimately, the decision of whether or not to cook chicken in olive oil is up to the individual and should depend on their overall health goals.
