What’s the best way to get an accurate reading?

You can get the most accurate temperature by sticking the thermometer into the center of the thickest part of the meat or casserole. Also, make sure it’s not touching any bone or gristle. For whole chickens and turkeys, the thickest part is where the thigh meets the rest of the body. For thin pieces of meat like hamburgers, stick the probe sideways into the meat.
