Can I put frozen meat in a slow cooker? I was wondering if I can put meat directly from the freezer into a slow-cooker. I want to be able to put chicken in the slow-cooker without having to let it defrost for a whole day in the fridge.

It is possible?
Per the USDA guidelines, frozen chicken should not be cooked in a slow-cooker or a microwave. It can only safely be cooked in the oven or on the stovetop.

A similar warning is given for beef as well.
