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. However, meat and poultry can be tricky to reheat properly 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.
Lock in moisture. The biggest issue with reheating chicken breasts, is losing moisture. To ensure that your breasts don't end up rubbery or dry, there are a few solutions. One option is adding liquid, like chicken broth or the leftover liquid from the original pan in which your chicken was prepared. Place the chicken in an oven-safe baking dish or wrap in tin foil, leaving an opening at the top, for steam to escape. Add the liquid. If you're reheating in a baking dish, use enough liquid to cover the bottom of the dish. If you're using foil, add about 1 tbsp. per chicken breast. If you don't have any liquid, wrap the chicken breasts in tin foil, leaving an opening at the top.
Reheat the chicken breasts for about 20 to 25 minutes or until they reach an internal temperature of 165 F.
Top chicken breasts with sauce, gravy or herbs to enhance the flavor.
According to the USDA, you should eat cooked chicken breasts within two days or discard them.
