Place 4 cups cold water and 2 large chicken breasts (about 1 lb., 4 oz. total) in a large saucepan. Season the water with salt.
Bring the water to a gentle boil, then cover with a lid and remove from heat.
Test the meat's doneness using a meat thermometer. Once it reaches an internal temperature of 150°F, remove the chicken from the water.
Let the chicken rest for 5 minutes, then slice and serve as desired.
