Creating these succulent meatballs is a straightforward process. Follow these step-by-step instructions to ensure your dish turns out perfectly:

Step 1: Prepare the Meatballs

1. Preheat your oven to 400°F (200°C).
2. In a large mixing bowl, combine ground beef, breadcrumbs, milk, egg, Parmesan cheese, minced garlic, onion powder, salt, black pepper, and parsley (if using).
3. Mix the ingredients thoroughly using your hands or a large spoon until well combined.
4. Shape the mixture into meatballs, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.

Step 2: Bake the Meatballs

5. Bake the meatballs in the preheated oven for 15-20 minutes, or until they are cooked through and browned on the outside.

Step 3: Prepare the Sweet and Spicy Glaze

6. While the meatballs are baking, prepare the glaze. In a small saucepan, combine ketchup, honey, soy sauce, sriracha, brown sugar, apple cider vinegar, garlic powder, and ginger powder.
7. Heat the mixture over medium heat, stirring frequently, until the glaze is smooth and slightly thickened. This should take about 5-7 minutes.

Step 4: Coat the Meatballs

8. Once the meatballs are done baking, remove them from the oven and allow them to cool slightly.
9. Transfer the meatballs to a large bowl and pour the sweet and spicy glaze over them. Gently toss the meatballs until they are evenly coated with the glaze.

Step 5: Serve

10. Serve the glazed meatballs immediately, garnished with additional parsley if desired.
