See, the thing is, potatoes really are pretty healthy, in and of themselves.
The problem with potatoes is all the junk we DO to them.
So if you want to eat potatoes - cook potatoes!
When I want to indulge in french fries, I make french fries, because otherwise if I'm eating french fries that have been drenched in oil and salt, I only allow myself a few.
They're really not hard, if you can keep your fingers out from under the knife!
Buy a BAG OF POTATOES.
I buy the Yukon gold ones, because they taste like butter, without adding any calories!
Win-Win.
Scrub them, cut out any bad spots, then start chopping them up into your preferred french fry size. I like a fry that's somewhere between the itty-bitty fast food ones and the big steak fries, myself, but you do you! Try to keep the size fairly even if you can. They'll cook better that way.
I toss the fries into a great big bowl as I'm cutting them. That's because when they're all cut, I spray them with OLIVE OIL PAN SPRAY - note that! I do not toss them in oil! - I spray them with pan spray, toss them, give them another coat, toss them, spray them again, until they're all coated.
I use LAWRY'S SEASONED SALT on mine. I do the same thing in that great big bowl, once they're all coated with pan spray, toss the seasoning salt on the top ones, toss them around, salt the top ones, toss them, and so on.
I have wire baskets for my oven, copper wire baskets that came as a set with copper baking sheets, so I bake my fries in my wire baskets so they crisp on the bottom too. A regular metal cookie sheet or baking sheet will do just fine, you might just want to turn them more often so they crisp all over.
I bake them at 400, stirring every 10 or 15 minutes, until they're done.
How long they take depends on how thick you've cut your fries! Just taste-test!
