Bring a large pot of salted water to a rolling boil. Add the spiral pasta and cook until al dente, about 8-10 minutes. Drain and set aside.

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add sliced smoked sausage and brown for 5-7 minutes.

Add 2-3 minced garlic cloves to the skillet and sauté for 1-2 minutes until fragrant.

Pour in 1 cup of heavy cream, stirring to combine. Let simmer for 2-3 minutes. Gradually mix in 1 cup of grated Parmesan cheese and 1-2 tablespoons of Cajun seasoning until the sauce is creamy.

Add the drained pasta to the sauce, tossing to coat evenly. If too thick, add a splash of reserved pasta water.

Serve the pasta in bowls, garnished with freshly chopped parsley.
