Preheat the oven to 375°F and line a loaf pan or sheet pan with parchment. Keep the pan ready so the loaf can go straight in after mixing.

Mix ground beef, 1/2 cup parmesan, Italian breadcrumbs, whole milk, eggs, 3 minced garlic cloves, onion, Italian seasoning, garlic powder, salt, and black pepper in a large bowl until just combined. Stop as soon as no dry pockets remain for a tender, juicy slice.

Shape the mixture into a loaf on the pan and smooth the top. Create an even surface so the crust browns uniformly.

Mix melted butter with the remaining minced garlic, then brush it over the loaf. Use a thin, even coat so you get a crackled parmesan crust as it bakes.

Pat the remaining parmesan over the entire surface. Press lightly so it adheres and browns deeply.

Bake at 375°F for 55–65 minutes, until the internal temperature reaches 160°F and the top is deeply golden. Watch for a firm, browned crust with a crackled look on the surface.

Let the meatloaf rest for 10 minutes before slicing. This helps the juices set so the interior stays moist instead of pooling.

Garnish with fresh parsley and slice to serve. Finish with a bright green pop on top for the classic family meatloaf look.
