Slice the chicken sausage links into ½-inch rounds and set them to the side. Dice the bell pepper and the onion. Mince the garlic cloves.
In a large pot with salted boiling water, add the pasta and cook according to the box instructions until al dente. Drain the pasta and set it to the side.
In a large, deep 12-inch skillet, heat 2 tablespoon of olive oil over medium heat. Add the chicken sausage and sauté for roughly 4-5 minutes until lightly browned on both sides. Remove the sausage to a separate plate and set aside.
To the same skillet, add the butter, diced bell pepper and diced onion. Sauté for 3-4 minutes just until the onion becomes translucent. Add the minced garlic and sauté for an additional 30 seconds.
Now add the fire roasted tomatoes, creole seasoning, garlic powder and salt. Stir to combine with the onion and peppers. Then add the chicken broth to the skillet and stir to combine.
Stir in the heavy cream and parmesan cheese. Simmer the sauce for 4-5 minutes until it begins to thicken.
Finally add back in the browned chicken sausage and the cooked pasta. Carefully stir everything together to combine. Allow the pasta to simmer on medium-low heat for 2-3 minutes so the sausage can heat back up with the sauce.
Remove the skillet from the heat and serve hot with freshly grated parmesan cheese on top and a pinch or two of crushed red pepper flakes (optional). Enjoy!
