1-: First, preheat the oven to 350°F (175°C) and line a rimmed baking sheet with parchment paper or foil for easy cleanup. Then, heat 1 teaspoon oil in a medium skillet over medium heat and sauté the chopped onions until softened and golden, about 5 to 7 minutes, then let them cool. In a large bowl, gently combine the ground beef, cooled onions, eggs, garlic, ketchup, parsley, breadcrumbs, milk, Italian seasoning, salt, and pepper without overmixing to avoid a tough result.

2-: Shape the mixture into a loaf about 8 inches long, 4 inches wide, and 3 inches tall, and place it on the prepared baking sheet. Bake uncovered for 40 minutes at 350°F (175°C) to get a good start on cooking. While it’s baking, prepare the glaze by mixing ketchup, white vinegar, brown sugar, garlic powder, and onion powder in a small bowl.

3-: Spread the glaze evenly over the meatloaf and bake for an additional 20 minutes or until the internal temperature reaches 160°F (71°C). Finally, let the meatloaf rest for 10 to 15 minutes before slicing to keep it juicy and easy to serve.
