To be fair, you can make really delicious homemade oven fries in about the same amount of time. Cut a potato into steak fries (the ones that look like planks instead of columns), parboil for ~10 minutes. Put some oil on an aluminum foil lined baking sheet and heat at 400F while the parboiled fries drain in a colander and cool for ~5 minutes. After 5 minutes, put the parboiled fries on the sheet pan and cook for 20 minutes at 400F. You can flip them halfway through to get a good crust on both sides. Season as desired immediately after pulling from the oven.
