For example, I just purchased 5.91 lbs of chicken breasts. Again, the idea is to get close to a half or whole pound weight so you can divide it into 8 oz servings.
If I divide this 5.91 lbs into 12 equal servings, each one will be 7.88 ounces. So I hit almost right on my 8 oz target without having to weigh anything!
If math isn’t your thing, you can also measure chicken with a kitchen scale. And you can do this before or after cooking.
First, you can weigh 8 oz of uncooked chicken breast on your scale. Or you can weigh multiples of 8 oz to divide up after cooking (16, 24, 32, etc.)
You can also weigh it after cooking if you don’t want to mess with raw chicken. Remember that chicken loses about 25% of its weight during cooking.
In practical terms, that means you should weigh 6 oz portions after cooking to get the same protein content as 8 oz of raw chicken breast.
