Prepare your Easy Creamy Sausage and Peppers Pasta by following these simple steps:

1. Cook the Pasta: In a large pot of salted boiling water, cook the penne pasta according to package instructions until al dente. Drain and set aside, reserving about 1 cup of pasta water.
2. Brown the Sausage: In a large skillet over medium heat, add the Italian sausage. Cook for about 5-7 minutes until browned and cooked through, breaking it apart with a spatula into bite-sized pieces. Remove from the skillet and set aside.

4. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes, until fragrant.
5. Create the Sauce: Pour in the heavy cream, stirring to combine. Allow it to simmer for about 2-3 minutes, then add the grated Parmesan cheese, stirring until melted and smooth.
6. Combine: Return the cooked sausage to the skillet and add the drained pasta. Mix well to combine, adding reserved pasta water as needed to achieve the desired consistency.
