Creating Creamy Broccoli Pasta is straightforward when you follow these clear steps:

1. Cook Pasta: In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente.
2. Add Broccoli: In the last 3 minutes of cooking the pasta, add the broccoli florets to the pot to blanch. Drain the pasta and broccoli together and set aside.
3. Sauté Garlic: In the same pot, heat olive oil over medium heat. Add the minced garlic and sauté until fragrant, about 1 minute.
4. Create Sauce: Lower the heat and pour in the heavy cream, stirring continuously. Allow to simmer for a minute until slightly thickened.
5. Mix in Cheese: Gradually stir in the grated Parmesan cheese until melted and the sauce is creamy.
6. Combine: Add the drained pasta and broccoli back into the pot. Toss to coat everything in the creamy sauce.
7. Season: Season with salt, pepper, and red pepper flakes (if using) to taste.
8. Serve Immediately: Serve hot, garnished with extra Parmesan cheese if desired.

These steps will guide you through preparing a delicious, creamy dish that is full of flavor and nutrition.
