Preparing Pasta alla Sorrentina is an enjoyable experience. Follow these steps to bring this delicious dish to life:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside.
2. Prepare the Sauce: In a large skillet, heat the olive oil over medium heat. Add minced garlic and sauté until fragrant, about 1 minute.
3. Add Tomatoes: If using fresh tomatoes, chop them and add to the skillet. For canned tomatoes, pour them in directly. Stir to combine and let simmer for about 10-15 minutes until the sauce thickens slightly.
4. Season: Add salt and pepper to taste. Adjust as necessary, ensuring the flavor is balanced.
5. Combine Pasta and Sauce: Add the drained pasta to the skillet, tossing well to coat the pasta evenly in the sauce.
6. Incorporate Cheese: Tear the mozzarella cheese into small pieces and add it to the pasta. Stir gently, allowing the cheese to start melting into the dish.
7. Transfer to Baking Dish: Pour the pasta and sauce mixture into a large baking dish or ovenproof skillet. Spread it evenly.
8. Top with Parmigiano-Reggiano: Sprinkle the grated Parmigiano-Reggiano cheese generously over the top.
9. Bake: Preheat your oven to 200°C (392°F) and bake the dish for about 10-15 minutes, until the cheese is bubbly and golden.
10. Garnish: Remove from the oven, let cool slightly, then garnish with fresh basil leaves.
