1. Preheat the Oven:
– Preheat your oven to 375°F (190°C).

2. Prepare the Meatloaf:
– In a large bowl, combine the ground beef, chopped onion, minced garlic, breadcrumbs, milk, egg, Worcestershire sauce, Dijon mustard, dried oregano, salt, and pepper. Mix until just combined, being careful not to overwork the meat.
– Shape the mixture into a loaf and place it on a baking sheet or in a loaf pan.

3. Make the Glaze:
– In a small bowl, mix together the ketchup, brown sugar, and apple cider vinegar.
– Spread half of the glaze over the top of the meatloaf.

4. Prepare the Potatoes:
– On the same baking sheet, or on a separate sheet, toss the halved baby potatoes with olive oil, garlic powder, dried thyme, salt, and pepper.
– Arrange the potatoes cut-side down around the meatloaf.

5. Bake:
– Bake in the preheated oven for 45-50 minutes, or until the internal temperature of the meatloaf reaches 160°F (71°C).
– Halfway through baking, spread the remaining glaze over the meatloaf.

6. Garnish and Serve:
– Once the meatloaf is done, let it rest for 10 minutes before slicing.
– Garnish the roasted potatoes with fresh parsley.
– Serve slices of meatloaf with the roasted potatoes on the side.

This classic meatloaf with roasted potatoes is a comforting and satisfying meal, perfect for any family dinner.
