Cooking in the air fryer is typically healthier because it allows you to cook with significantly less oil than oven cooking or deep frying. Frozen french fries, however, are deep fried prior to being frozen, so they are not necessarily lower in oil. If you want to make homemade potatoes that are not deep fried, try my Air Fryer Smashed Potatoes, Sweet Potatoes, or even Butternut Squash or Air Fryer Carrots for an extra healthy twist.
