Follow these simple steps to create a delightful Chicken Sausage and Broccoli Pasta:

1. Cook the Pasta:
   • Bring a large pot of salted water to a boil. Add the pasta and cook according to the package instructions until al dente. Reserve 1 cup of pasta water, then drain the pasta and set aside.
2. Prepare the Broccoli:
   • In the last 3-4 minutes of the pasta cooking time, add the broccoli florets to the boiling water with the pasta. This will blanch the broccoli, making it tender-crisp. Drain along with the pasta and set aside.
3. Cook the Chicken Sausage:
   • In a large skillet, heat olive oil over medium heat. Add the sliced chicken sausage and cook until browned and cooked through, about 5-7 minutes. Remove from the skillet and set aside.
4. Sauté the Garlic:
   • In the same skillet, add minced garlic and red pepper flakes (if using). Sauté for about 1 minute until fragrant.
5. Create the Sauce:
   • Add the chicken broth to the skillet, scraping any browned bits from the bottom. Let it simmer for about 2 minutes to reduce slightly.
6. Combine Ingredients:
   • Return the cooked chicken sausage to the skillet. Add the cooked pasta and broccoli. Toss everything together until well combined.
7. Add Lemon Zest and Cheese:
   • Stir in the lemon zest and grated Parmesan cheese, ensuring everything is well-coated. If the sauce seems too thick, add reserved pasta water, a little at a time, until desired consistency is reached.
8. Season and Serve:
   • Season with salt and pepper to taste. Garnish with chopped parsley before serving.
