- Preheat Oven:
- Preheat your oven to 375°F (190°C).
- Prepare Meatballs:
- In a bowl, combine ground beef, breadcrumbs, Parmesan cheese, chopped parsley, garlic powder, onion powder, salt, pepper, and the egg. Mix until well combined.
- Form the mixture into meatballs, about 1 inch in diameter.
- In a skillet, brown the meatballs over medium heat until they are cooked through. You don’t need to fully cook them at this stage, as they will continue cooking in the oven.
- Pour marinara sauce over the meatballs, coating them evenly.
- Prepare Potatoes:
- In a separate bowl, toss the sliced potatoes with olive oil, salt, pepper, and dried thyme.
- Assemble the Casserole:
- In a greased baking dish, layer the sliced potatoes at the bottom.
- Place the partially cooked meatballs on top of the potatoes.
- Pour any remaining marinara sauce over the meatballs.
- Sprinkle shredded mozzarella cheese on top.
- Bake:
- Cover the baking dish with foil and bake in the preheated oven for about 30-35 minutes or until the potatoes are tender.
- Remove the foil and bake for an additional 10-15 minutes or until the cheese is melted and golden brown.
- Garnish and Serve:
- Garnish with chopped fresh parsley before serving.
- Serve Warm:
