While a grill pan is primarily designed for grilling food, you can also use it to fry certain items. However, it's important to note that the grill pan's raised ridges may be better for frying foods that require complete immersion in oil, such as deep-frying. Instead, you can use a grill pan to pan-fry items like chicken breasts, fish fillets, or vegetables. The ridges allow excess fat to drain away, resulting in a healthier cooking method compared to traditional frying.
