Classic American meatloaf with a tangy ketchup glaze is the definition of family comfort food. This high protein, budget-friendly dinner slices beautifully and makes excellent leftovers for the next day.
Preheat your oven to 350°F (175°C) and lightly grease a loaf pan.
In a large bowl, combine ground beef, breadcrumbs, milk, eggs, finely diced onion, and grated carrot until just mixed—avoid overworking the meat.
Add salt, black pepper, garlic powder, and Worcestershire sauce; gently fold these ingredients in, ensuring even seasoning throughout.
Shape the mixture into a loaf and place it into the prepared pan. Spread half of the ketchup evenly over the top for a moist glaze.
Bake for 60–70 minutes, checking occasionally; in the last 10 minutes, brush with the remaining ketchup for a glossy finish. Rest for 10 minutes before slicing.
