No shot you can recreate anything close to McDonald’s fries without a fryer and that alone is worth it. Even say fries and a milkshake. No premade milkshake and fries will touch a real fryer and ice cream machine
Fries - no idea, I can have them but why I'd want fries home is another story; the frozen potatoes in the oven are pretty decent and no extra oil, so that's okay; again not especially enticing. If you have grown an acquired taste for McDonalds fries, so be it. At least where I live I know no one who'd say they wish to go to McDonalds for the fries.
