Healthier Easy Meatloaf

1 ½ pounds lean ground beef

1 egg

1 onion, chopped

1 cup low-fat (1%) milk

1 cup whole wheat bread crumbs

½ cup chopped fresh parsley

1 large carrot, grated

salt and ground black pepper to taste

1 tablespoon brown sugar

2 tablespoons prepared mustard

⅓ cup ketchup

Preheat oven to 350 degrees F (175 degrees C). Lightly grease a 9x5-inch loaf pan.

Combine beef, egg, onion, milk, bread crumbs, parsley, and carrot in a large bowl. Season with salt and black pepper. Place beef mixture in loaf pan.

Stir together brown sugar, mustard, and ketchup in a small bowl. Pour over meatloaf.

Bake in preheated oven until no longer pink in the center, about 1 hour. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C).
