1. Prepare the Mixture: In a large mixing bowl, combine the ground beef, breadcrumbs, grated Parmesan cheese, egg, milk, minced garlic, onion powder, dried parsley, salt, and black pepper.

2. Mix Thoroughly: Using your hands, gently mix all the ingredients together until just combined. Be careful not to overmix, as this can make the meatloaf tough. You want everything evenly distributed.

3. Form the Bites: Take about 1.5 to 2 tablespoons of the meat mixture and roll it into a small, uniform ball. Aim for golf-ball size or slightly smaller. Place the formed bites on a clean plate or baking sheet as you go.

4. Preheat Air Fryer: Preheat your air fryer to 375°F (190°C) for about 3-5 minutes. Some air fryers don’t require preheating, so check your model’s instructions.

5. Arrange in Air Fryer: Lightly spray the air fryer basket with olive oil spray. Carefully arrange the meatloaf bites in a single layer in the basket. Do not overcrowd the basket; cook in batches if necessary to ensure even cooking and browning.

6. Air Fry the Bites: Air fry for 10-14 minutes, flipping them halfway through (at about 5-7 minutes). The cooking time will vary depending on the size of your bites and your specific air fryer model.

7. Check for Doneness: The meatloaf bites are done when they are golden brown on the outside and cooked through. An instant-read thermometer inserted into the center of a bite should register 160°F (71°C).

8. Serve Immediately: Carefully remove the Air Fryer Garlic Parmesan Meatloaf Bites from the basket. Serve them hot and enjoy!
