In a large pot or Dutch oven, heat the olive oil over medium heat.
Add the sliced chicken sausage and cook for about 5-7 minutes until browned.
Stir in the minced garlic, diced bell pepper, and sliced zucchini. Sauté for an additional 3-4 minutes until the vegetables soften.
Pour in the chicken broth and add the penne pasta to the pot. Stir well to combine.
Bring the mixture to a boil, then reduce the heat to a simmer. Cover and cook for 12-15 minutes, stirring occasionally, until the pasta is al dente and most of the liquid is absorbed.
Stir in the heavy cream, grated Parmesan cheese, and Italian seasoning. Mix until the cheese is melted and the pasta is coated in a creamy sauce.
Season with salt and pepper to taste.
Remove from heat and let it sit for a couple of minutes to thicken slightly.
Garnish with fresh basil leaves before serving.
