For the crispiest texture, avoid overcrowding the baking sheet or air fryer basket so hot air can circulate around each fry. If needed, cook in two batches rather than stacking the fries. Different zucchini sizes and coatings can affect browning time, so watch closely near the end of cooking and remove once the coating is deep golden and firm to the touch. Leftovers can be refrigerated in an airtight container for up to 3 days and reheated in a hot oven or air fryer until re-crisped; avoid microwaving, which can make the fries soggy. Feel free to customize the seasoning blend with extra garlic powder, cayenne for heat, or additional Italian herbs while keeping everything keto-friendly.
