Creating your Meatball & Mashed Potato Bake is simple if you follow these steps:

1. Preheat Oven: Preheat your oven to 400°F (200°C) to prepare for baking.
2. Make Meatballs: In a bowl, combine ground beef, breadcrumbs, Parmesan cheese, egg, garlic powder, onion powder, Italian seasoning, salt, and pepper. Mix until well combined and form into small meatballs.
3. Cook Meatballs: Heat a skillet over medium heat. Add meatballs and cook until browned on all sides (about 5-7 minutes). Transfer cooked meatballs to a baking dish.
4. Prepare Mashed Potatoes: In a large pot, boil the cubed potatoes until fork-tender (approximately 15-20 minutes). Drain the water.
5. Mash Potatoes: While potatoes are still hot, add milk, butter, salt, and pepper. Mash until smooth and creamy. Adjust seasoning as needed.
6. Layer Ingredients: Spread the creamy mashed potatoes evenly over the meatballs in the baking dish.
7. Add Cheese: Sprinkle shredded cheese over the mashed potatoes, ensuring even coverage.
8. Bake: Place the baking dish in the preheated oven and bake for 20-25 minutes or until the cheese is melted and bubbly.
9. Serve: Once cooked, allow to cool for a few minutes before serving. Garnish with fresh parsley if desired.
