Nope. Not gonna work for long. Electronics and interior burners aren’t meant to be exterior. Any anything in a covered kitchen needs an exhaust hood too. Or you’ll asphyxiate yourself.

Does it plug in at all or 100% gas?

If it will be fully protected from blowing rain & snow then it would likely work from a purely practical standpoint. The question then is safety (water & electricity don't do well when mixed) and if a building inspector will allow it.

And then there are degrees of covered/protected. If one or two walls of a normal indoor kitchen are stackable sliding glass doors that allow those sides to be completely 100% open then how does that differ from a regular indoor kitchen? If your porch then had similar sliding glass doors or even just a clear vinyl roll down then what is it? At what point is something indoors or out of doors?
