Preheat the oven to 180°C.
Soak the bread cubes in the milk.
Sauté the onions in a pan over medium heat until golden yellow. Transfer them to a bowl with the ground meat.
Add the soaked bread, egg, and breadcrumbs. Season with salt, pepper, marjoram, and garlic to taste, then stir the mixture thoroughly until you have a solid consistency.
Shape the meat into a loaf form and place it in a baking dish.
Bake for approximately 40 minutes until golden brown.
Serve hot with potatoes, caramelized onions, and salad.
