Some foods taste better as leftovers the next day after the flavours have more time to meld. Meat and poultry can be tricky to reheat properly, however, without overcooking the meat and rendering it rubbery. To reheat chicken breasts in an oven, closely monitor the reheating progress and follow a few easy steps to ensure that the chicken tastes just as good as or better than the day you first prepared it.
Preheat your oven to 180 degrees C (350F).
Brush both sides of the chicken breasts with olive oil to help crisp the outside.
Place chicken breasts in a small cake tin or a baking pan with sides.
Reheat the chicken breasts uncovered for about 20 to 25 minutes or until they reach an internal temperature of 75 degrees C (165F).
Top chicken breasts with sauce or gravy to enhance the flavour.
Eat cooked chicken breasts within two days or discard them.
