It is not preferred in the cooking world but okay to do as long as you ensure that your chicken is cooked fully.
sometimes its not okay because you could get sick so I prefer not to
No, not at all. This method of cooking has been done for a long time. This is okay to cook this way.
Sauerkraut that has been frozen won't be unsafe, but may have a different texture than before.
Sure, it's okay to cook but you probably shouldn't eat it afterwards. In other words, no...unless you like suffering from food poisoning.
It depends on the food, but in the grocery store where I work we have to throw frozen meat out within three hours of losing power. If you are planning to cook the meat right away it should still be good. Especially if the meat is still cold. If kept in the fridge it should be okay for another day or two.
Chicken is never okay outside of the fridge or freezer. If it's left out more than 20 or 30 minutes, I would throw it out.
I would say still okay to cook eat. The safest thing to do is NOT eat them. Think of it this way: thank goodness you turned the oven off!
they dont have to be cooked first they can still be frozen then cook or visa virsa
That would not be a good idea. If you start the chicken first and get it almost completely cooked and then add the shrimp, you would be okay. If you start them at the same time, the shrimp will be terrible overdone and rubbery. If you pull the shrimp out as soon as it is done, it will be contaminated by the still raw chicken.
Only if they are thawed, NOT if frozen. Swallowing of frozen foods can cause stomach cramps and digestive trouble.
It is not OK to add raw chicken to a cooked chicken casserole. It would be safer to cook the raw chicken separately, then add it to the cooked casserole when reheating if you will be eating it all at once. Otherwise, keep the freshly cooked chicken separately to avoid reheating it several times.
