Creating the delicious Creamy Broccoli and Chicken Penne is easy when you follow these steps:

1. Cook Pasta: In a large pot, bring water to a boil. Add penne pasta and cook according to package instructions until al dente. Drain and set aside.
2. Steam Broccoli: In the last 3 minutes of pasta cooking, add broccoli florets to the pot to steam them until tender.
3. Cook Chicken: In a large skillet, heat olive oil over medium heat. Add the diced chicken. Season with salt and pepper. Cook until the chicken is browned and fully cooked, about 6-8 minutes.
4. Add Garlic: Incorporate minced garlic into the skillet with chicken and sauté for about 1 minute until fragrant.
5. Prepare Sauce: Pour in heavy cream and chicken broth; stir to combine. Bring to a simmer and cook for 3-4 minutes, allowing the sauce to thicken slightly.
6. Mix in Cheese and Seasonings: Stir in grated Parmesan cheese and Italian seasoning. Mix until cheese is melted and the sauce is creamy.
7. Combine Ingredients: Add the cooked penne pasta and steamed broccoli into the skillet. Toss everything together until well-coated in the sauce.
8. Taste and Adjust: Check for seasoning, adjusting salt and pepper as necessary.
9. Serve Immediately: Remove from heat and garnish with freshly chopped parsley before serving.

These steps ensure that your Creamy Broccoli and Chicken Penne comes together seamlessly, resulting in a magnificent dish.
