Preheat Oven or Heat Pan : Preheat oven to 375°F (190°C) for baking or heat a skillet with olive oil for pan-frying.
Prepare Meatballs : In a bowl, combine ground meat, breadcrumbs, Parmesan, egg, minced garlic, Italian seasoning, salt, and pepper. Mix well. Form into 12–16 meatballs.
Cook Meatballs : Oven Method : Place meatballs on a parchment-lined baking sheet and bake 18–20 minutes until cooked through.
Skillet Method : Heat olive oil in a skillet over medium heat. Cook meatballs, turning occasionally, until browned and cooked through (about 12–15 minutes).
Add Eyeballs : Top each meatball with a small mozzarella ball or cube. Place a black olive slice in the center to create an eyeball effect.
Cook Spaghetti : Boil spaghetti according to package instructions until al dente. Drain and toss with marinara sauce.
Assemble Dish : Serve spaghetti on a plate, top with eyeball meatballs, and drizzle extra marinara sauce around the plate. Garnish with fresh basil or parsley if desired.
