Creating Creamy Sausage Pasta is straightforward, and you can achieve it in just a few simple steps:

1. Cook the Pasta: In a large pot, boil salted water. Add the pasta and cook according to package instructions until al dente. Drain and set aside, reserving about 1/2 cup of pasta water.

2. Brown the Sausage: In a large skillet over medium heat, add olive oil. Once hot, add the sausage. Cook, breaking it apart with a spoon, until browned and cooked through, about 5-7 minutes.

3. Add Garlic: Stir in the minced garlic and cook for another minute, until fragrant.

4. Create the Sauce: Pour in the chicken or vegetable broth, scraping any browned bits from the pan. Add the heavy cream, Italian seasoning, and red pepper flakes (if using). Stir well and bring to a gentle simmer.

5. Combine Pasta and Sauce: Add the cooked pasta to the skillet, tossing to combine. If the sauce is too thick, add some reserved pasta water until you reach your desired consistency.

6. Add Cheese: Stir in the grated Parmesan cheese. Continue to stir until the cheese is melted and the sauce is creamy.

7. Season to Taste: Taste the dish and adjust seasoning with salt and pepper as necessary.

8. Serve: Remove from heat and transfer to serving plates. Garnish with chopped parsley for a touch of color.
