Preparation Steps

• Preheat your oven to 375°F (190°C). Grease a loaf pan or line a baking sheet with parchment paper.
• In a large bowl, combine the ground beef, breadcrumbs, milk, beaten eggs, finely chopped onion, minced garlic, salt, and black pepper. Mix gently until just combined. Do not overmix.
• Form the meat mixture into a loaf shape and place it in the prepared pan or on the baking sheet.
• In a small bowl, whisk together the ketchup, brown sugar, and Worcestershire sauce for the glaze.
• Spread the glaze evenly over the top of the meatloaf.
• Bake for 50 minutes.
• Remove the meatloaf from the oven, top with shredded Swiss cheese and caramelized onions. Return to the oven and bake for another 20 minutes, or until the cheese is melted and bubbly and the meatloaf is cooked through (internal temperature reaches 160°F or 71°C).
• Let the meatloaf rest for 10 minutes before slicing and serving.
