How much liquid do you need in a crock pot?

Then, do you need liquid in a slow cooker?

So no, you need not add any water when cooking with a crockpot, at least when you're cooking something with enough moisture of its own to cook in, which I suspect would be all meats and vegetables, as long as the lid works.

Likewise, can you put meat in slow cooker without liquid? Braising liquid: Slow cookers work by creating steam that braises the meat until it's tender, which is why you can't make a roast in a slow cooker with no liquid.

Also Know, is it safe to use a slow cooker without liquid?

Yes. For example though, if you throw some boneless, skinless chicken thighs into the slow cooker with zero liquid they will cook just fine. As they cook, they provide their own juices so no additional liquid is required if you don't want to use any.

Does meat in slow cooker need to be covered with liquid?

It doesn't matter if it is covered or not. The inside of the slow cooker will be warm enough to cook the meat. Braising (not submerged) and simmering (submerged) are two methods which both can lead to good results. Roasts should be roasted, not slow cooked.
