MEATLOAF COOKING TIME AT 350 RECIPES

Steps:

• Make the meatloaf: Heat oven to 350 degrees and grease a rimmed baking sheet with oil. Heat 2 tablespoons oil in a medium skillet over medium. Add onion and cook, stirring occasionally, until softened, about 5 minutes. Add garlic and cook, stirring, until fragrant, about 2 minutes. Stir in tomato paste until well combined; let cool.
• In a large bowl, combine bread and milk, and mash with a spoon until a paste forms. Add eggs, parsley, salt, pepper, thyme and cooled onion mixture and mix until well blended. Add the beef, pork and veal, and mix gently to combine, being careful not to overwork the meat. Divide mixture into 2 equal portions and shape each into a 4-by-8-inch meatloaf on the prepared baking sheet.
• Make the glaze: In a small bowl, whisk together ketchup and Worcestershire sauce until smooth. Use a spoon to spread mixture over the top and sides of each meatloaf. Bake until nicely browned and an instant-read thermometer inserted in the center of meatloaf registers 160 degrees, 45 to 55 minutes. Let rest for 15 minutes before slicing.

Steps:

• Preheat oven to 350° and grease a 9"-x-5" loaf pan with cooking spray. In a large skillet over medium heat, melt butter. Add onions, carrots, and celery. Season with salt and pepper and cook, stirring occasionally, until soft, 5 minutes. Add thyme and garlic and cook until fragrant, 1 minute more. Turn off heat and stir in Worcestershire sauce and tomato paste. Let cool slightly.
• In a large bowl, combine vegetable mixture, ground beef, bread crumbs, and eggs. Press into prepared loaf pan. 
• In a small bowl, whisk together ketchup and brown sugar. 
• Brush meatloaf with half the ketchup mixture and bake for 45 minutes. Brush with remaining ketchup mixture and bake for another 15 to 20 minutes or until the middle of the loaf reaches 155°. Let cool 15 minutes.
