I begin by setting my oven to 375 °F (190 °C). I line my loaf pan with parchment paper or lightly grease it so nothing sticks later.
In my large bowl, I combine ground chicken, grated Parmesan, panko, eggs, minced garlic, garlic powder, onion powder, basil, parsley, salt, pepper, and milk. I gently fold until just combined—overmixing makes it tough.
I shape the mixture into a loaf (either by hand or pressed into the pan). Then I bake it for about 40–45 minutes until the center is close to 165 °F.
While the meatloaf bakes, I melt butter in a small saucepan, sauté the minced garlic briefly, stir in Parmesan and parsley, and let it thicken slightly.
Once the loaf is nearly done, I pull it out and brush the glaze generously over the top. Then I return it to the oven for another 5–7 minutes so the glaze bubbles and sets.
I remove it and let it rest for 5–10 minutes before slicing. Letting it rest ensures slices stay intact and juicy.
