1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and set aside.
2. Cook the penne pasta according to package instructions until al dente. Drain and set aside.
3. In a large skillet over medium heat, add olive oil. Season the chicken pieces with Cajun seasoning, salt, and pepper.
4. Cook the chicken until fully cooked, about 6-8 minutes, stirring occasionally. Remove the chicken from the skillet and set aside.
5. In the same skillet, add the diced bell peppers and garlic. Sauté for 3-4 minutes until the peppers are softened.
6. Add the softened cream cheese and chicken broth to the skillet, stirring until the cream cheese is fully melted and the sauce is smooth.
7. Return the cooked chicken to the skillet and combine with the sauce.
8. Add the cooked pasta to the skillet, tossing everything together until well coated with the sauce.
9. Transfer the pasta mixture to the prepared baking dish. Sprinkle the mozzarella and Parmesan cheese evenly over the top.
10. Bake in the preheated oven for 15-20 minutes, or until the cheese is bubbly and golden brown.
11. Remove from the oven and let it cool for a few minutes. Garnish with chopped parsley before serving.

As you go through these steps, remember that cooking is a dance, not a race. Enjoy the process and the aromas that fill your kitchen. It’s this joy that makes home cooking so special.
