Cook pasta according to package directions, preferably al dente (firm to the bite); keep warm.
For sauce, in a large skillet cook sausage, mushrooms, bell pepper, onion, and garlic until sausage is brown. Drain fat.
Stir whipping cream and basil into sausage mixture; season with salt and pepper. Cook over medium-low heat for 5 to 8 minutes or until slightly thickened, stirring occasionally. Remove from heat. Stir in Parmesan cheese.
