1. Heat the olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the sliced sausage and cook until browned and slightly crisp, about 5 minutes. I like to get a nice sear on the sausage—it adds that irresistible caramelized flavor.
2. Remove the sausage with a slotted spoon and set it aside, leaving the rendered fat in the pot.
3. Add the chopped onion and bell pepper to the pot. Sauté until softened and fragrant, about 4 minutes. Stir in the minced garlic and cook for another 30 seconds—you’ll know it’s ready when the kitchen smells like pure comfort.
4. Sprinkle the Cajun seasoning and smoked paprika over the veggies and stir well to coat everything evenly.
5. Pour in the chicken broth and heavy cream, scraping the bottom of the pot to loosen any browned bits—that’s flavor gold!
6. Add the uncooked pasta to the pot. Stir to combine, making sure the pasta is submerged in the liquid. Bring everything to a simmer, then reduce the heat to medium-low and cover the pot.
7. Cook for about 12-15 minutes, stirring occasionally to prevent the pasta from sticking. The pasta will absorb the liquid and become tender, while the sauce thickens beautifully.
8. Once the pasta is cooked and the sauce is creamy, stir the browned sausage back into the pot. Add the Parmesan cheese, if using, and season with salt and pepper to taste.
9. Let everything warm through for another 2 minutes. The cheese will melt and bring everything together into a luscious, dreamy sauce.
10. Garnish with chopped fresh parsley before serving to add a pop of color and freshness.

From personal experience, I find that stirring occasionally during cooking is key—it keeps the pasta from clumping and helps the sauce thicken evenly. And don’t rush the simmering step; it’s where the magic really happens.
