Method
- Preheat your oven to 350 F. Line a baking sheet with foil or lightly grease a 9x5-inch loaf pan.
- In a small bowl, combine the 1 cup breadcrumbs and 0.75 cup milk and let sit for 5 minutes so the crumbs soften and soak up the liquid; this step keeps the meatloaf moist instead of dense.
- In a large bowl, add the 2 lb ground beef, the soaked breadcrumb mixture, 2 eggs, the diced onion, 3 cloves minced garlic, 0.25 cup parsley, 2 teaspoons salt, 1 teaspoon pepper, and 1 tablespoon Worcestershire sauce.
- Mix everything together gently with clean hands just until combined; overmixing compacts the meat and makes the loaf dense and rubbery, so stop as soon as you no longer see streaks of egg or dry breadcrumbs.
- Turn the mixture out onto the prepared baking sheet and shape into a loaf about 9 inches long, 5 inches wide, and 2.5 inches tall, or press it evenly into the loaf pan. A free-form loaf on a sheet pan browns better on the sides than one baked in a deep pan.
- In a small bowl, whisk together 0.5 cup ketchup, 2 tablespoons brown sugar, and 1 tablespoon mustard to make the glaze. Spread half of the glaze evenly over the top and sides of the loaf.
- Bake at 350 F for 40 minutes, then remove from the oven and brush the remaining glaze over the top.
- Return to the oven and bake for another 15-20 minutes, until an instant-read thermometer inserted into the center of the loaf reads at least 160 F, the USDA-recommended safe minimum internal temperature for ground beef; the glaze should look slightly darkened and sticky at the edges.
- Let the meatloaf rest for 10 minutes before slicing; cutting too soon lets the juices spill out onto the cutting board instead of staying in the meat, leaving it dry.
- Slice into thick pieces with a sharp knife and serve warm.
Tips
Soaking the breadcrumbs in milk before mixing (a panade) is what keeps ground beef from turning dense and dry once baked; do not skip this step or substitute dry breadcrumbs directly into the mix.
Always confirm doneness with a thermometer rather than by color alone, since ground beef can look done on the outside while still being under 160 F in the center.
