It is safe to eat chef Boyardee without heating it up.
The Chef Boyardee canned foods are all cooked and ready to eat.
While you can eat Chef Boyardee without heating it up, it tastes much better heated up and is more enjoyable.
During the canning process of the Chef Boyardee Ravioli and other Chef Boyardee foods, the ingredients including any meats are cooked during the canning process.
Once the ingredients are added into the can and the can is sealed, the Chef Boyardee canned foods are then placed in a large pressure cooker machine that cooks the foods inside and so they are ready to heat up and eat from the can.
Many people prefer to heat the Chef Boyardee canned foods in a pan or microwave before eating to make them taste better, but you can simply open the can and eat the Chef Boyardee straight from the can or empty it into a bowl or plate and eat it cold or at room temperature.
All canned foods including canned meats are also cooked through pressure cooking during the canning process, but heating up the canned foods makes them taste better.
