Some ovens have a very low simmer setting that will melt cheese, gently simmer sauces and soups or heat up leftovers slowly. Simmer settings generally adjust the temperature of the food in the pot to approximately 140 degrees Fahrenheit.
The low setting is ideal for a faster simmer, for slowly pan-cooking chicken, lamb, pork or another type of meat. This temperature will vary, depending on the type of oven and the surroundings, but it will range around 195 degrees Fahrenheit.
The medium setting is ideal for cooking vegetables, such as onions, asparagus and broccoli. It ranges from 210 to 300 degrees Fahrenheit, depending on the type of oven.
The high setting will quickly create a crispy crust on meats or heat oil to a very high temperature at which you can fry tortillas, donuts or another type of dough. This ranges from 300 to 500 degrees Fahrenheit.
