Creating Pasta alla Sorrentina is simple when you follow these straightforward steps:

1. Boil Water: In a large pot, bring salted water to a boil for cooking the pasta.
2. Cook Pasta: Add the pasta to the boiling water and cook according to package instructions until al dente. Drain and set aside.
3. Prepare Sauce: In a large skillet, heat the olive oil over medium heat. Add the minced garlic and sauté for about a minute, or until fragrant.
4. Add Tomatoes: Pour in the crushed tomatoes, stirring to combine with the garlic. Add sugar, salt, and pepper, adjusting the seasoning to your taste. Allow to simmer for about 10 minutes.
5. Combine: Once the sauce has thickened slightly, add the drained pasta to the skillet, stirring until the pasta is well-coated in the sauce.
6. Incorporate Cheese: Remove the skillet from the heat and fold in the diced mozzarella and half of the grated Parmesan cheese, ensuring the cheese starts to melt as it mixes with the warm pasta.
7. Transfer to Baking Dish: Preheat your oven to 200°C (390°F). Transfer the pasta mixture to a baking dish and even out the top.
8. Top with Cheese: Sprinkle the remaining Parmesan cheese over the pasta, adding more mozzarella on top if desired.
9. Bake: Place the baking dish in the preheated oven and bake for about 15-20 minutes, or until the cheese is bubbly and golden.
10. Finish Up: Remove from the oven and let cool for a few minutes. Garnish with fresh basil leaves before serving.

Each step brings you closer to a delightful and comforting dish that will impress your family and friends, ensuring a joyful dining experience.
