Raw or cooked chicken can be stored in a refrigerator for a few days, though it’s important to prevent raw chicken juices from leaking and contaminating other foods. Ensure that chicken remains in its original packaging (which should be vacuum-sealed or tightly-wrapped) until it is ready to be cooked.
While freezing will make your chicken less tender and juicy, it is the perfect way to store the family-sized pack you bought at Costco last weekend. Remove the chicken from its original packaging and rewrap it tightly using aluminum foil, plastic wrap, or freezer paper. Double wrap if you are planning to store the chicken for more than two months. Ground chicken can last up to three months in the freezer, while chicken pieces can last up to nine.
You should never thaw chicken at room temperature, as it is highly susceptible to bacteria growth. Frozen chicken should either be thawed in the microwave, in the refrigerator, or in cold water (which should be changed every 30 minutes).
Memorial Day
Cover with a piece of aluminum foil that just covers the breasts. 
Place the second frying pan on top of the foil covering the chicken breasts. 
Transfer the chicken to a warm platter and let rest for 10 minutes while you make the sauce.
Add the butter in pieces, whisking it into the sauce until the sauce is smooth and silky. 
Transfer the chicken to warmed serving plates and spoon over the sauce.
