Ingredients

  • 1 pound ground beef or turkey
  • 1/2 cup breadcrumbs
  • 1/4 cup grated Parmesan cheese
  • 2 cloves garlic minced
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste
  • 2 cups mashed potatoes prepared
  • 1 cup marinara sauce
  • 1 cup shredded mozzarella cheese
  • 2 tablespoons olive oil
  • Fresh parsley for garnish (optional)

Instructions

Prepare the Meatball Mixture

  • In a large mixing bowl, combine the ground beef or turkey with breadcrumbs, grated Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and pepper. Mix thoroughly until evenly incorporated.

Form and Cook the Meatballs

  • Shape the mixture into small, bite-sized meatballs about 1 inch in diameter. Heat olive oil in a large skillet over medium heat. Add the meatballs in batches, cooking 5-7 minutes, turning occasionally until browned and cooked through. Remove from heat and set aside.

Assemble the Casserole

  • Preheat oven to 375°F (190°C). Spread prepared mashed potatoes evenly in a baking dish. Layer cooked meatballs over the potatoes. Pour marinara sauce evenly over the meatballs and potatoes.

Add Cheese and Bake

  • Sprinkle shredded mozzarella cheese evenly on top. Bake for 20-25 minutes until cheese is melted, bubbly, and golden around edges.

Garnish and Serve

  • Remove casserole from oven and let cool slightly. Garnish with fresh parsley if desired before serving.

Notes

  • Avoid overmixing the meat mixture to keep meatballs juicy and tender.
  • Use leftover mashed potatoes to save time and ensure a creamy base.
  • For a spicier kick, add red pepper flakes to the meatball mixture or marinara sauce.
