In a bowl, mash the ripe avocados. Add lime juice, finely diced red onion, diced tomato, chopped cilantro, salt, and pepper. Mix until well combined.
Take small portions of the guacamole mixture and shape them into bite-sized balls or small patties.
Roll each guacamole bite in panko breadcrumbs until evenly coated, pressing gently to ensure the breadcrumbs adhere.
Set your air fryer to 370°F (185°C) and let it preheat for a few minutes.
Place the coated guacamole bites in a single layer in the air fryer basket, making sure they are not touching.
Lightly spray the tops of the guacamole bites with cooking spray. Air fry for 8-10 minutes till crispy and golden brown. Flip the bits halfway through cooking for even browning.
Keep a close eye on the guacamole bites as cooking times may vary based on your air fryer model. Adjust the time as needed.
Once done, transfer the air-fried guacamole bites to a plate and let them cool for a few minutes. Serve with your favorite dipping sauce or enjoy them as is.
