1. Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Drain, reserving 1 cup of pasta water.
2. In a large skillet, heat the olive oil over medium heat. Add the garlic and red pepper flakes, sautéing until the garlic is golden and fragrant, about 2 minutes.
3. Add the crushed tomatoes to the skillet, stirring well to combine with the garlic and oil. Let the sauce simmer, allowing it to thicken slightly, for about 10 minutes.
4. Stir in the fresh basil, salt, and pepper. Taste and adjust seasoning as needed.
5. Add the cooked pasta to the sauce, tossing to coat. If the sauce is too thick, add reserved pasta water a little at a time until the desired consistency is reached.
6. Sprinkle with Parmesan cheese and toss again to distribute the cheese evenly. If using, add cooked chicken or shrimp for extra protein.
7. Serve hot, with additional Parmesan cheese and basil leaves as garnish.

This recipe is a true homage to the simple, flavorful meals in my grandmother’s kitchen, where each ingredient was chosen with care and every meal was a celebration.
