Classic Meatloaf

Instructions

1. Preheat the oven to 350°F (175°C) and grease a 9 x 5 in (23 x 13 cm) loaf pan with cooking spray.
2. Melt the butter in a large skillet over medium heat. Add the onion, carrot, and celery; season with salt and pepper and cook, stirring occasionally, until softened, about 5 minutes.
3. Add the thyme and garlic and cook until fragrant, about 1 minute. Remove from the heat and stir in the Worcestershire sauce and tomato paste. Cool slightly.
4. Combine the cooled vegetable mixture, ground beef, bread crumbs, and eggs in a large bowl. Mix just until combined, then press into the prepared loaf pan.
5. Stir together the ketchup and brown sugar. Brush half over the meatloaf.
6. Bake for 45 minutes. Brush with the remaining glaze and bake for another 15-20 minutes, until the center reaches at least 160°F (71°C).
7. Rest for 15 minutes before slicing. Garnish with parsley.
