Preheat the Oven:
Preheat your oven to 375°F (190°C).
Make the Meatloaf Mixture:
In a large mixing bowl, combine ground beef, breadcrumbs, onion, garlic, eggs, milk, Worcestershire sauce, ketchup, salt, pepper, and parsley (if using).
Mix gently with your hands or a spatula until just combined—don’t overmix.
Shape and Place in Pan:
Transfer the meat mixture to a greased loaf pan and press it in evenly.
Alternatively, shape it into a loaf on a parchment-lined baking sheet for crispier edges.
Prepare the Glaze:
In a small bowl, whisk together ketchup, brown sugar, mustard, and Worcestershire sauce.
Spread half the glaze over the top of the meatloaf.
Bake:
Bake for 40 minutes.
Remove from oven and spread the remaining glaze on top.
Return to oven and bake for another 15–20 minutes, or until the internal temperature reaches 160°F (71°C).
Rest and Slice:
Let the meatloaf rest for 10 minutes before slicing. This helps the juices redistribute and keeps it moist.
Serve:
Slice and serve with your favorite sides—mashed potatoes, green beans, roasted veggies, or mac and cheese.
