Note: this would also taste great with veggie beef crumbles. I added 1 cup chopped celery to my meatloaf.
1/2 cup chopped onion
6 tablespoons ketchup, divided
1/2 cup panko (Japanese breadcrumbs)
1/4 cup chopped fresh flat-leaf parsley
1 teaspoon Worcestershire sauce
3/4 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon freshly ground black pepper
1 pound ground sirloin
1 large egg white
1. Preheat oven to 350°.
2. Heat a small skillet over medium heat. Coat pan with cooking spray. Add onion to pan; cook 6 minutes or until tender, stirring occasionally. Remove from heat; cool slightly. Combine onion, 3 tablespoons ketchup, and remaining ingredients in a bowl, and gently stir just until combined.
3. Place meat mixture on a baking sheet coated with cooking spray; shape into an 8 x 4-inch loaf. Brush top of loaf with remaining 3 tablespoons ketchup. Bake at 350° for 35 minutes or until a thermometer registers 160°. Let stand 10 minutes; cut into 8 slices.
