Creating your Melt-in-Your-Mouth Garlic Parmesan Chicken Meatloaf is a straightforward process. Follow these steps to achieve perfection:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Prepare a loaf pan by lightly greasing it or lining it with parchment paper.
2. Mix Ingredients: In a large mixing bowl, combine the ground chicken, breadcrumbs, grated Parmesan cheese, milk, eggs, minced garlic, onion powder, Italian seasoning, salt, pepper, and parsley.
3. Combine Thoroughly: Using your hands, mix all the ingredients until fully integrated. Avoid overmixing, as this can lead to a dense meatloaf.
4. Shape the Mixture: Transfer the meat mixture into the prepared loaf pan, shaping it into a loaf.
5. Add Topping: If desired, spread ketchup over the top of the meatloaf to add moisture and flavor.
6. Bake: Place the loaf pan in the preheated oven and bake for approximately 40 minutes, or until the internal temperature reaches 165°F (75°C).
7. Cool Slightly: Once cooked, remove the meatloaf from the oven and let it cool for about 5-10 minutes before slicing. This step helps keep it moist.
8. Slice and Serve: Carefully slice the meatloaf with a serrated knife for the best results.

By following these steps, you will create an incredible Melt-in-Your-Mouth Garlic Parmesan Chicken Meatloaf that everyone will enjoy.
