Preheat your oven to 425°F (220°C) to achieve a crispy exterior.
Slice the large avocados in half, remove the pit, and scoop out the flesh. Cut each half into wedges of even size for uniform cooking. Optionally, drizzle with lime juice to prevent browning.
Set up a dredging station: in one bowl, mix flour with salt and pepper; in a second bowl, beat the egg until smooth; in a third bowl, pour the panko bread crumbs.
Coat each avocado wedge first in the flour mixture, shaking off excess, then dip into the beaten egg, and finally coat generously with panko bread crumbs.
Arrange the coated avocado wedges in a single layer on a baking sheet lined with parchment paper, ensuring they are not touching. Drizzle oil evenly over the fries.
Bake in the preheated oven for 15-20 minutes until golden brown and crispy, watching closely to prevent burning.
While baking, prepare the chipotle dipping sauce by combining chipotle peppers in adobo sauce with Greek yogurt or mayonnaise. Adjust spice level to taste.
Remove fries from the oven, let cool briefly, and serve hot with the chipotle dipping sauce.
