Bring a large pot of salted water to a boil. Add the bowtie pasta and cook according to package instructions until al dente. Drain and set aside.

In a large skillet, heat olive oil over medium heat. Add the chicken pieces and Cajun seasoning. Cook until the chicken is browned and cooked through, about 5-7 minutes.

Add the diced bell pepper, onion, and garlic to the skillet with the chicken. Sauté until the vegetables are soft, about 3-4 minutes.

Pour in the chicken broth and bring to a simmer. Stir in the heavy cream and Parmesan cheese, mixing until the cheese is melted and the sauce is creamy.

Add the cooked pasta to the skillet and toss to coat in the sauce. Cook for an additional 2-3 minutes until heated through. Garnish with chopped parsley before serving.
