It depends. Pan-frying can be unhealthy if you use low-quality oil, overheat it, so it burns, or use a lot of fat. We have three tips to make pan-fried tofu healthier: 1) Use good quality extra virgin olive oil. Extra virgin olive oil has more antioxidants than most oils. Antioxidants protect the oil while it cooks, making it healthier for you. 2) Use lower heat. High heat will damage the oil, making it unhealthy. If the oil smokes, it means it's been damaged by the heat. Keep the heat to medium for healthier pan-fried tofu. 3) You don't need a lot of oil, but you do need some. Start with 1.5 - 2 tablespoons and add more if you think the pan is too dry or want tastier fried tofu.
