Creating Creamy Baked Ziti with Broccoli & Alfredo Sauce involves following these straightforward steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Cook the Pasta: In a large pot, boil salted water and cook the ziti according to package instructions until al dente. Drain and set aside.
3. Prepare the Broccoli: In the same pot, add a little olive oil over medium heat. Sauté the broccoli florets for about 3-4 minutes until bright green and slightly tender. Remove from heat.
4. Combine Ingredients: In a large mixing bowl, combine the cooked ziti, sautéed broccoli, Alfredo sauce, garlic powder, salt, and pepper. Mix until everything is evenly coated.
5. Layer the Ziti: In a greased baking dish, pour half of the pasta mixture. Sprinkle half of the mozzarella cheese on top.
6. Add More Mixture: Pour the remaining ziti mixture into the dish and top with the remaining mozzarella and Parmesan cheese.
7. Bake: Cover with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden.
8. Let it Set: Once baked, let the dish rest for about 5 minutes before serving to allow the flavors to meld.
9. Garnish: Sprinkle with fresh parsley if desired for added color and flavor.

These steps will help you create a dish that not only looks amazing but tastes incredible too.
