Won't the heat and time required for frozen fries end up cooking off a lot of volatiles like garlic, chili, pepper and the like?
It sure didn't taste like it :V
At least for air frying, frozen spud only needs to cook for, like... two or three more minutes at the same heat, or something like that? There's barely any difference in cooking time between frozen and homemade, and pre-seasoned home fries come out the cooker tastin' even better than they do if you season after you pull them out, least to me.
So that... might be a concern if you're oil/deep frying? I don't
think it would, because the last few times I've actually used an oil fryer with pre-seasoned
home fries, while some of the seasoning did come off in the cooking oil, most of it cooked into the fries real well -- and as with air frying, doing frozen doesn't actually change your cooking profile much in terms of time or heat.
Most other cooking methods it's definitely neither hot enough nor cooked long enough to burn off much seasoning, in any case. Like, idle checking suggests it happens to some degree, but from what I've seen all my life, if you throw a pile of black pepper (or whatever) onto spud before cooking it, there's still going to be a pile of black pepper on it even if some amount of it cooks off, and that's true if you're boiling it, baking it, frying it, air frying it, microwaving it, pan cooking it, grilling it, steaming it, and probably some method or another I'm forgetting. I can't remember if I've broiled or braised potatoes before, but now I kinda' wanna' try braised potatoes...
