I've got a ton of leftover potroast & veggies (potatoes, onion, carrots, mushrooms) that I want to serve for dinner this evening. I want to re-heat it, but I'm not sure which way is the best. I cooked it in a slow cooker, and I would like to re-heat it this way if possible, but I am scared of burning the potatoes or something. I saved all the juices and gravy... do you think it will be alright if I warm it on low in the crock pot? How long will this take?
