For some people, their favorite aspect of a delicious meal is the leftovers. Certain foods simply taste better the next day after flavors 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 350 F.
Brush both sides of the chicken breasts with olive oil to help crisp the outside.
Place chicken breasts on a jelly roll pan 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 165 F.
