Putting the rubbery chicken into a braising liquid of any kind, even a simple one of water and spices, and allowing it to cook low and slow, will completely break down the protein fibers making the chicken soft and tender again.
I’ve done this with rubbery chicken, steak even pork chops.
What does it mean when chicken is rubbery?
Over cooking the meat or cooking beyond the required time can make the chicken lose its moisture and make it hard to chew/swallow. It also makes the meat dry and tasteless at a point. Sudden change in temperature can also make the meat lose its texture and become rubbery.
Is rubbery chicken undercooked?
It’s most likely you overcooked it if it’s chewy. Undercooked chicken is like mush and most people overcook chicken rather than undercook it.
How do you fix undercooked chicken?
Place the meat in an oiled roasting pan or Dutch oven; drizzle it with some stock, sauce, or water; cover it with aluminum foil; and bake the whole thing in a 400° F oven until cooked. Poultry is cooked when the meat has an internal temperature of 165 ° F, or when its juices run clear.
