aaah that just doesn't sound very normal! if you were to say that to a native they would probably look at you funny... theres probably some kind of grammar rule behind it but I dont actually know it! take my word for it though, it sounds weird
This might be splitting hairs, but inanimate masculine/neuter nouns do have an accusative case, it is just the same as nominitive case. The noun after готовить is put into the accusitive case technically, it's just the same as the nominitive case.
