Yes! Chicken thighs, as with any other type of food, can be overcooked. This is easier to do than you may think, and can happen for several reasons. Overcooked chicken does not make for a pleasant eating experience (unless your goal is some chicken jerky, of course).
Often, when chicken thighs are overcooked it is because they have been left to cook for too long. Another reason may be that the heat is too high. It may even be a mixture of both of these reasons!
To avoid overcooking your chicken thighs, ensure they are at the right temperature and cooked for the right amount of time. They can handle longer and hotter than other types of chicken such as the breast, but that doesn’t mean you should just leave them at a high temperature for a long time.
The ideal temperature for chicken thighs is between 175 and 195 degrees Fahrenheit. They can take between 20 to 30 miniatures if they are boneless thighs, or around 15 minutes more if the bone is left in.
