Directions:

Preheat oven to 375°F (190°C).
In a large bowl, mix together ground beef, breadcrumbs, onion, garlic, milk, eggs, Worcestershire sauce, salt, pepper, smoked paprika, and parsley until well combined.
Transfer the mixture to a loaf pan or shape it into a loaf on a baking sheet.

In a small bowl, whisk together ketchup, brown sugar, apple cider vinegar, and mustard powder for the glaze. Spread half of the glaze evenly over the meatloaf.

Bake for 1 hour or until the meatloaf is cooked through (internal temperature of 160°F or 71°C). Halfway through the baking time, spread the remaining glaze over the meatloaf.
Let the meatloaf rest for 10 minutes before slicing. Serve warm.
