- Cook the pasta according to package instructions until al dente. Drain and set aside. 
- In a large skillet over medium heat, add the olive oil and sausage. Cook until the sausage is browned. 
- Add garlic and Cajun seasoning. Cook for about 1 minute, just until fragrant. 
- Pour in chicken broth and heavy cream. Stir well and bring to a gentle simmer. 
- Stir in Parmesan cheese. Let the sauce thicken slightly. 
- Add cooked pasta to the skillet and toss everything together until the pasta is coated. 
- Season with salt and pepper to taste. Sprinkle with fresh parsley if you're feeling fancy. 
- Serve warm and eat immediately — or cold from the fridge at midnight, no judgment.
