- 2 1/2 lb ground beef
- 1/2 onion, minced
- 1 rib celery, minced
- 3 cloves garlic, minced
- 1 Tbsp chopped fresh flat-leaf parsley
- 1 1/4 cups fine breadcrumbs
- 2 eggs, lightly beaten
- 1/2 cup milk
- Salt and freshly ground pepper
- 5 Tbsp ketchup
- 1 1/4 tsp Dijon mustard
- 1 1/4 tsp Worcestershire sauce
Preheat oven to 350°. Spray a loaf pan with cooking spray and place on a rimmed baking sheet.
In a bowl, combine beef, onion, celery, garlic, parsley, breadcrumbs, eggs, milk, and season with salt and pepper. In a small bowl, combine ketchup, mustard, and Worcestershire sauce. Set aside.
Mix meatloaf ingredients with hands until ingredients are combined, but don’t overmix. Transfer mixture to loaf pan and place on baking sheet. Slather ketchup-mustard mixture over meatloaf. Bake until lightly browned, bubbling, and an instant-read thermometer reads 160°, 1- 1 hour 15 minutes.
