Creating Salisbury Meatballs and Mashed Potatoes is simple if you follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C) if you plan to bake the meatballs.
2. Prepare Meatball Mixture: In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, chopped onion, milk, egg, Worcestershire sauce, garlic powder, salt, and black pepper. Mix until well incorporated.
3. Form Meatballs: Shape the mixture into meatballs, about 1 inch in diameter. Set aside.
4. Brown Meatballs: In a large skillet, heat olive oil over medium heat. Add the meatballs in batches, browning them on all sides. Remove and set aside.
5. Prepare Gravy: In the same skillet, add beef broth and bring to a boil. If desired, stir in cornstarch mixed with a little water for thickening.
6. Combine Meatballs and Gravy: Once the gravy is thickened, return the meatballs to the skillet, ensuring they’re coated with the gravy. Let them simmer for 10 minutes.
7. Prepare Mashed Potatoes: While the meatballs are simmering, make your mashed potatoes according to your preferred recipe.
8. Serve: Spoon the meatballs and gravy over a generous portion of mashed potatoes, and garnish with fresh parsley if desired.
