1-First, preheat your oven to 350°F (175°C) and line a rimmed baking sheet with parchment paper or foil for easy cleanup. This sets the stage for even cooking and helps with browning. Gather all your ingredients to make the process smooth and fun.

2-Next, heat oil in a medium skillet over medium heat and sauté the chopped onion for 5 to 7 minutes until it’s softened and golden; let it cool a bit before moving on. This step adds a mellow sweetness that enhances the overall flavor. In a large bowl, mix the ground beef, sautéed onions, eggs, garlic, ketchup, parsley, breadcrumbs, milk, Italian seasoning, salt, and pepper gently until combined, taking care not to overmix for a tender result.

3-Then, shape the meat mixture into a loaf about 8 inches long, 4 inches wide, and 3 inches tall on the prepared baking sheet. This free-form shape allows for crispy edges and even baking. Pop it in the oven uncovered for 40 minutes to start building that juicy interior.

4-While it’s baking, combine the sauce ingredients in a small bowl for a quick glaze. After the initial bake, remove the meatloaf, spread the sauce evenly on top, and return it to the oven for another 20 minutes or until it reaches 160°F (71°C) internally for beef. Let it rest for 10 to 15 minutes before slicing to keep those juices locked in.
