01 - Rinse the rice under cold water until water runs clear. Combine rice, 2 cups water, and 1/2 tsp salt in a saucepan. Bring to a rolling boil over high heat, then reduce heat to low, cover tightly, and simmer for 15 minutes until liquid is absorbed. Remove from heat and let stand covered for 5 minutes before fluffing with a fork.
02 - Pat chicken pieces dry with paper towels. In a medium bowl, combine 1 tbsp Cajun seasoning, smoked paprika, black pepper, and 1/2 tsp salt. Add chicken pieces and toss until evenly coated on all sides.
03 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add seasoned chicken in a single layer without overcrowding. Cook for 5-7 minutes, turning occasionally, until golden brown and cooked through to an internal temperature of 165°F. Transfer chicken to a plate and set aside.
04 - In the same skillet over medium heat, add diced red onion and bell peppers. Sauté for 3-4 minutes until vegetables begin to soften and edges are slightly charred. Add minced garlic and cook for 1 minute until fragrant, being careful not to burn.
05 - Pour chicken broth into the skillet, using a wooden spoon to scrape up any browned bits from the bottom. Reduce heat to medium-low and stir in heavy cream and softened cream cheese. Continue stirring until cream cheese melts completely and sauce becomes smooth and bubbly.
06 - Return browned chicken to the skillet along with any accumulated juices. Add remaining 1/2 tbsp Cajun seasoning and grated Parmesan cheese. Stir gently until sauce coats everything evenly and chicken is heated through. Simmer for 3-4 minutes until sauce reaches desired consistency.
07 - Divide fluffy white rice evenly among 4 serving bowls. Spoon generous portions of creamy Cajun chicken and vegetables over the rice. Garnish with fresh sliced green onions and chopped parsley. Serve immediately while hot.
