The Timing Difference When Cooking Bone-In Chicken Thighs Vs Boneless
A medium-high heat of 400 F is recommended for chicken thighs. At this temperature, bone-in thighs will take 40 to 45 minutes, and boneless thighs will take 10 to 15 minutes less.
The dark meat found in chicken thighs requires more time to cook than white meat due to its higher fat content and connective tissue. Bone-in thighs further complicate this.
The bone acts as a natural insulator and slows down the cooking process. This, combined with the thigh's thickness, means the heat takes longer to penetrate and cook it properly.
