Bring a large pot of salted water to a boil. Add the 8 ounces of penne pasta and cook according to package instructions until al dente, usually about 10-12 minutes. Once cooked, drain the pasta using a colander and set aside. Reserve a cup of pasta water to loosen the sauce later if needed.
Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the turkey sausage (with casings removed) and cook, breaking it apart with a wooden spoon, until browned and cooked through, about 6-8 minutes. Transfer the cooked sausage to a plate and set aside.
In the same skillet, add the minced garlic and sauté for about 1 minute until fragrant, making sure it doesn’t burn.
Pour in the 28-ounce can of crushed tomatoes. Stir in 1 teaspoon dried basil, salt, and pepper to taste. Let the sauce simmer gently for 10 minutes so the flavors meld beautifully.
Reduce the heat to low and stir in 1 cup of heavy cream. Return the cooked turkey sausage to the skillet and mix everything until combined. Sprinkle in 1/2 cup grated Parmesan cheese and stir until melted and creamy. If the sauce feels too thick, add reserved pasta water a tablespoon at a time to reach your preferred consistency.
Add the cooked penne pasta to the skillet and toss until every piece is well coated in the luscious, creamy tomato basil sauce.
Serve hot, garnished with fresh basil leaves for a burst of color and fresh herbal aroma. Pair with a crisp salad or garlic bread for a complete meal.
