For best texture, use firm but ripe avocados that give slightly when pressed but are not mushy so they hold their shape while baking. If preparing the fries a bit ahead, you can lightly toss the slices in lemon or lime juice before coating to slow browning without adding significant carbs. To reheat leftovers, warm them in a 350°F oven or air fryer for a few minutes until crisp again, avoiding the microwave, which softens the coating. Add a pinch of cayenne or chili powder to the breading mix for a spicy version, or use Italian seasoning and extra Parmesan for a pizza-inspired flavor.
