Step 1: Preheat your oven to 375°F (190°C). This ensures that the oven is at the right temperature when you're ready to bake, which is crucial for even cooking.
Step 2: In a large bowl, combine ground chicken, Parmesan cheese, breadcrumbs, parsley, minced garlic, beaten egg, oregano, salt, and pepper. Mix gently but thoroughly to ensure all ingredients are evenly distributed. Mixing too vigorously can make the meatloaves dense.
Step 3: Add the milk into the mixture. This helps to maintain a moist texture. Again, combine until just mixed.
Step 4: Shape the mixture into four mini loaves and place them on a baking sheet. Drizzle with olive oil, which will help create a golden crust during baking.
Step 5: Bake the loaves in the preheated oven for 25-30 minutes or until the internal temperature reaches 165°F (74°C). Check with a meat thermometer for best results. Let them rest for a few minutes before serving to allow the juices to redistribute.
