#### Instructions
1. **Boil Water**: Bring a large pot of salted water to a boil (about 1 tablespoon of salt).
2. **Cook the Spaghetti**: Add the spaghetti to the boiling water and cook according to package instructions until al dente (8-10 minutes). Stir occasionally.
3. **Reserve Pasta Water**: Before draining, reserve about 1 cup of the pasta water.

5. **Melt the Butter**: In a large skillet over medium heat, melt the butter.
6. **Sauté the Garlic**: Add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to brown it.
7. **Add Red Pepper Flakes**: Stir in the red pepper flakes (if using) and cook for an additional 30 seconds.
8. **Pour in the Heavy Cream**: Slowly add the heavy cream, stirring continuously, and bring to a gentle simmer for 2-3 minutes.
9. **Incorporate the Cheeses**: Gradually add the Parmesan and mozzarella cheese, stirring until melted and creamy. If too thick, add reserved pasta water to reach desired consistency.
10. **Season the Sauce**: Taste and season with salt and pepper as needed.
11. **Add the Spaghetti**: Toss the drained spaghetti in the sauce until well coated. Add more reserved pasta water if necessary.
12. **Heat Through**: Allow the spaghetti to heat through in the sauce for 1-2 minutes, stirring occasionally.
