Medium high heat on a grill ranges between 375 and 450 degrees Fahrenheit. It is ideal for cooking hamburgers, sliced vegetables, fish, chicken pieces, planked fish, and large vegetables. This temperature will still sear your food, but it also allows food to cook slower and more thoroughly.
Its important to note that the temperature range for medium-high heat may vary depending on the type of stove or grill being used. For example, on an electric stove, medium-high heat may be around 450°F, while on a gas stove, medium heat may be around 350-375°F.
In general, its best to use a thermometer to measure the temperature of the cooking surface to ensure that it is at the desired temperature.
