Preheat the oven to 375 degrees and lightly grease a loaf pan.
Place the ground beef in a large bowl and add the breadcrumbs, egg, onion, smoked paprika, salt, and black pepper.
Mix everything with your hands or a spoon until the ingredients are evenly combined but not overworked.
Transfer the mixture to the prepared loaf pan and press it into an even shape.
Spread the ketchup over the top in a thin layer.
Bake for 50 to 55 minutes until the internal temperature reaches 160 degrees.
Remove from the oven and let the meatloaf rest in the pan for 10 minutes before slicing.
