01 - Preheat oven to 400°F. Lightly grease a 9x13 inch baking dish.
02 - Combine all meatball ingredients in a large bowl. Mix gently until just combined. Roll into 24 small meatballs, about 1 tablespoon each.
03 - Heat olive oil in a large skillet over medium-high heat. Brown meatballs on all sides for approximately 5 minutes. They do not need to be cooked through. Transfer to a plate.
04 - Cook pasta in salted boiling water for 2 minutes less than package directions. Drain well.
05 - In the prepared baking dish, combine partially cooked pasta, marinara sauce, and water. Stir well to coat evenly.
06 - Nestle browned meatballs evenly into the pasta mixture. Sprinkle mozzarella and Parmesan cheese over the top.
07 - Cover tightly with foil and bake for 25 minutes.
08 - Remove foil and continue baking for 15 to 20 minutes, until cheese is golden and sauce is bubbling.
09 - Let rest for 10 minutes before serving. Garnish with fresh basil leaves.
