A 100g serving of crinkle cut fries has 130–140 calories frozen, about 165 calories air fried, and up to 310 calories deep fried, based on USDA FoodData Central and manufacturer data. The fries themselves are the same — it's the cooking method that decides the calorie count.
Here's the thing most people don't realize: frozen crinkle cut fries from the bag are already par-fried at the factory. They're coated in a thin layer of oil before freezing. That means they'll crisp up in an air fryer or oven without adding a single drop of oil. The taste? Practically the same as deep fried. The calories? About half.
