Creating delicious Salisbury Steak Meatballs is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
2. Mix Meatball Ingredients: In a large bowl, combine ground beef, chopped onion, breadcrumbs, milk, egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix until just combined; avoid overmixing.
3. Shape the Meatballs: Form the mixture into 1-inch meatballs and place them on the prepared baking sheet.
4. Bake Meatballs: Bake the meatballs in the preheated oven for about 20-25 minutes or until they are cooked through and browned on the outside.
5. Prepare the Gravy: In a skillet, heat olive oil over medium heat. Once hot, add beef broth and bring it to a simmer.
6. Thicken the Gravy (optional): For thicker gravy, mix cornstarch with two tablespoons of cold water in a small bowl. Gradually whisk this mixture into the simmering broth until desired thickness is achieved.
7. Combine Meatballs and Gravy: Once the meatballs are cooked, add them to the skillet with the gravy. Simmer for an additional 5 minutes, allowing the flavors to meld.
8. Garnish: Sprinkle freshly chopped parsley over the meatballs for added flavor and presentation.
