Boil the spiral pasta according to the package instructions until it reaches al dente. Once cooked, drain the pasta and set it aside.
In a large skillet, heat the olive oil and sauté the sliced smoked sausage until it is nicely browned. Add the minced garlic and continue to cook until it becomes fragrant.
Pour in the heavy cream, and then add the grated Parmesan cheese, Cajun seasoning, salt, and pepper. Stir the mixture until the sauce starts to thicken.
Add the cooked pasta to the skillet and toss everything together to ensure the pasta is well coated in the sauce.
