For old-fashioned meatloaf, organize 2 cups onion, 1 tablespoon garlic, 1 celery rib, 1 carrot and 1/2 cup scallion. Also gather 3/4 pounds ground pork, 1 1/2 pound ground chuck, 2 eggs, 2 tablespoons butter and 1/3 cup parsley. You also need 2/3 cup ketchup and 1 cup breadcrumbs.
Chop the onion, parsley, carrot, celery and scallion. Mince the garlic and set it aside with the other vegetables. Melt butter in a large skillet over medium heat, adding the vegetables except for the parsley, cooking them for approximately five minutes or until tender. Add the Worcestershire sauce, half the ketchup, and pepper and salt to taste. Allow to simmer, stirring ingredients together for an additional minute.
In a large bowl, combine chopped parsley, bread crumbs, beaten eggs, pork and chuck. Add contents of the skillet and stir everything together. Take a greased, shallow baking pan and form the mixture into a loaf with dimensions roughly 10 by five inches. Take the remainder of the ketchup and spread it evenly atop the uncooked loaf.
Place the pan in a 350-degree Fahrenheit oven for one hour, then check the internal temperature with a meat thermometer to ensure that it has achieved at least 155 degrees Fahrenheit. Insert the end of the thermometer into the center of the loaf for the most accurate reading.
