re: Pot of red beans on stove overnight

Only detail I'd like to see is pot type.

I'd feel a bit more comfortable if it was ceramic cast iron, for instance - that would hold heat much longer.

You are likely fine, but all of the previous replies on the "danger zone" are legit.

If the pot was covered and hot when you turned it off, pretty unlikely any microbes had a sex party overnight.

I see you added "cooked sausage" before you killed the fire...was said sausage cold? That's an added risk factor.

Key word in all of this is "risk" - you are mostly likely fine regardless.
