Now, let’s get cooking! This step-by-step guide will make the process a breeze, even if you’re juggling a busy schedule.

1. Preheat your oven to 375°F (190°C) and lightly grease a baking dish with olive oil.
2. In a large bowl, combine the ground beef, breadcrumbs, Parmesan, egg, garlic, oregano, salt, and pepper. Mix until just combined—avoid over-mixing to keep the meatballs tender.
3. Shape the mixture into golf ball-sized meatballs and place them into the prepared baking dish.
4. Bake the meatballs for 15-20 minutes, or until they are browned and cooked through. This step was always my favorite as a child, watching my abuela work her magic with meatballs.
5. While the meatballs are baking, prepare your mashed potatoes if you haven’t already. I love using russet potatoes for their fluffy texture, but feel free to use your favorite kind.
6. Once the meatballs are ready, spread the mashed potatoes evenly over the top of the meatballs.
7. Sprinkle the shredded mozzarella cheese over the mashed potatoes, ensuring an even layer for that golden, bubbly top.
8. Return the dish to the oven and bake for another 20 minutes, or until the cheese is melted and golden brown.
9. Remove from oven and let it cool slightly before sprinkling with fresh parsley. This final touch always reminds me of the vibrant dishes my family would serve, each one a testament to our love for fresh ingredients.
