This savory homestyle meatloaf is a comforting and flavorful dish, perfect for family dinners or gatherings.
Preheat your oven to 350°F (175°C).
Preheating ensures even cooking from the start.
In a large mixing bowl, combine the ground beef, onion, tomato sauce, breadcrumbs, egg, salt, and black pepper.
Mix gently to avoid overworking the meat, which can make the loaf dense.
Shape the mixture into a loaf and place it in a baking dish.
Use a spatula to smooth the surface for even cooking.
In a small bowl, mix together the ketchup, brown sugar, and mustard to make the glaze.
Adjust the sweetness or tanginess of the glaze to your preference.
Spread the glaze evenly over the top of the meatloaf.
Use a spatula for an even coating.
Bake the meatloaf in the preheated oven for 1 hour, or until the internal temperature reaches 160°F (71°C).
Check the temperature with a meat thermometer for accuracy.
Let the meatloaf rest for 10 minutes before slicing and serving.
Resting allows the juices to redistribute, making the slices neater.
