Follow these simple steps to create your Meatball & Mashed Potato Bake:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Meatballs:
– In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, parsley, egg, garlic, salt, pepper, and Italian seasoning.
– Mix gently until combined, but do not overwork the meat.
3. Form Meatballs:
– Shape the mixture into small meatballs (about 1 inch in diameter) and place them on a baking sheet.
4. Bake Meatballs:
– Bake the meatballs in the preheated oven for about 20 minutes or until cooked through and browned.
5. Cook Potatoes:
– While the meatballs are baking, place the cubed potatoes in a large pot and cover with water.
– Bring to a boil and cook until tender, about 15 minutes.
6. Mash Potatoes:
– Drain the potatoes and return them to the pot. Add milk, butter, salt, and pepper.
– Mash until smooth and creamy.
7. Prepare Sauce:
– In a skillet, heat olive oil over medium heat and add marinara sauce.
– If desired, stir in red pepper flakes for some heat. Simmer for 5 minutes.
8. Assemble Bake:
– In a greased baking dish, spread a layer of marinara sauce on the bottom.
– Add the cooked meatballs on top, then layer with mashed potatoes, smoothing the top.
9. Top with More Sauce:
– Pour any remaining marinara sauce over the potatoes for added flavor.
10. Bake:
– Bake the assembled dish for an additional 15-20 minutes until heated through and the top is lightly golden.
11. Cool Slightly:
– Allow to cool for a few minutes before serving.
