Step 1: Preheat the oven
Preheat your oven to 375°F (190°C) and lightly grease a baking sheet or loaf pan.

Step 2: Prepare the meatloaf mixture
In a large mixing bowl, combine ground chicken, breadcrumbs, Parmesan cheese, eggs, minced garlic, chopped onion, milk, parsley, Italian seasoning, salt, and black pepper.

Step 3: Mix thoroughly
Using clean hands or a wooden spoon, mix until all ingredients are evenly combined. Do not overmix, as this can make the meatloaf dense.

Step 4: Shape the loaf
Transfer the mixture onto the prepared baking sheet or into the loaf pan. Shape into a loaf approximately 8×4 inches.

Step 5: Brush with olive oil
Lightly brush the top with olive oil to encourage browning and a crispy crust.

Step 6: Bake to perfection
Bake in the preheated oven for 45–50 minutes, or until the internal temperature reaches 165°F (74°C).

Step 7: Add cheesy topping (optional)
During the last 10 minutes of baking, sprinkle shredded mozzarella on top and return to the oven to melt.

Step 8: Rest and slice
Remove from the oven and let the meatloaf rest for about 5–10 minutes before slicing to allow the juices to redistribute.
