Creating this creamy baked ziti dish is straightforward when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Cook the Pasta: In a large pot, bring water to a boil. Add the ziti pasta and cook according to package instructions until al dente. Drain and set aside.
3. Blanch the Broccoli: In the same pot, add the fresh broccoli florets to boiling water for 2 minutes. Drain and immediately place them in ice water to stop cooking. This keeps the broccoli bright and crunchy.
4. Combine Ingredients: In a large mixing bowl, combine the cooked ziti, blanched broccoli, alfredo sauce, garlic powder, onion powder, salt, and pepper. Stir well to ensure everything is evenly coated.
5. Prepare for Baking: Transfer the mixture to a greased baking dish. Top it with shredded mozzarella cheese and grated parmesan cheese.
6. Bake: Place the baking dish in the preheated oven. Bake for 25-30 minutes, or until the cheese is melted and bubbly, and the top is lightly golden.
7. Garnish and Serve: Once done, remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley if desired.

Following these steps will ensure that your Creamy Baked Ziti with Broccoli & Alfredo Sauce turns out perfectly every time!
