A bone-in chicken thigh requires approximately 20 to 30 minutes of cooking time, while deboned chicken thighs can be fully cooked within a span of 15 to 20 minutes on the stovetop.
The most important step you have to follow before boiling the chicken is to ensure it is clean. Make sure the cut doesn’t have any feathers on it, any dirt, or any blood.
If the water is simmering, it is working at a lower temperature. Even though it is slightly below boiling, it still makes a difference. And even more so if the water is simply warm and not simmering.
The more meat there is to cook, the longer the center will take to reach the correct internal temperature. Bigger thighs will mean the answer to “how long to boil chicken thighs” is longer.
