For this chicken caprese recipe, you want melted, bubbling cheese and a nice golden brown color on the chicken. Since each breast gets seared on the stovetop first, it usually only takes about 15 minutes in a 350-degree F oven.  A meat thermometer is the best way to know for sure that your poultry is fully cooked. Insert one into the thickest part of the chicken breast and ensure it has reached an internal temperature of 165 degrees F.
