01 - Rinse the rice under cold water until the water runs clear. In a medium saucepan, combine rice, chicken broth, and salt. Bring to a boil, then cover and reduce heat to low. Simmer for 15 minutes until the broth is absorbed and the rice is tender. Remove from heat and allow to steam, covered, for 5 minutes.
02 - Toss chicken breast pieces with Cajun seasoning, coating all sides evenly.
03 - Heat olive oil in a large skillet over medium-high heat. Add seasoned chicken and cook for 5 to 7 minutes, stirring occasionally, until golden brown and cooked through. Transfer the chicken to a plate and keep warm.
04 - In the same skillet, add the diced red pepper, yellow pepper, red onion, and minced garlic. Cook over medium heat for 3 to 4 minutes until softened.
05 - Reduce heat to medium-low. Add heavy cream, milk, and cream cheese to the skillet. Stir constantly until the cheese melts and the sauce becomes smooth.
06 - Stir grated parmesan, smoked paprika, and cayenne pepper into the sauce, then season with salt and black pepper to taste.
07 - Return the cooked chicken and any accumulated juices to the skillet. Stir to coat the chicken in the sauce and simmer gently for 2 to 3 minutes until heated through.
08 - Fluff the rice and divide evenly among four bowls. Spoon the creamy Cajun chicken mixture over the rice. Garnish each serving with chopped parsley and a lemon wedge if desired. Serve immediately.
