For a gourmet twist on French fries, try making pesto Parmesan air fryer French fries using a food processor. Slice the potatoes into thin strips using the food processor, then toss them in pesto sauce, grated Parmesan cheese, salt, and pepper. Air fry until crispy and golden brown. The combination of the fragrant pesto and the savory Parmesan cheese creates a unique and delicious flavor profile for the fries. Serve them as an appetizer or side dish for a fancy meal.
