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, reduce to low, cover tightly, and simmer for 15 minutes. 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 large bowl, toss chicken with 1 tbsp Cajun seasoning, smoked paprika, black pepper, and 1/2 tsp salt 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, working in batches if necessary to avoid 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, add diced onion and bell peppers. Sauté for 3-4 minutes, stirring occasionally, until vegetables begin to soften and edges develop slight char. Add minced garlic and cook for 1 minute until fragrant, being careful not to burn.
05 - Reduce heat to medium. Pour in chicken broth, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Stir in heavy cream and softened cream cheese, whisking continuously until completely smooth and incorporated.
06 - Return browned chicken to the skillet along with any accumulated juices. Add remaining 1/2 tbsp Cajun seasoning and grated Parmesan. Stir well to coat everything in the sauce. Simmer for 3-4 minutes until sauce thickens slightly and chicken is heated through. Adjust seasoning with additional salt if needed.
07 - Divide cooked rice evenly among four serving bowls. Top with generous portions of creamy Cajun chicken and sauce. Garnish generously with sliced green onions and chopped fresh parsley. Serve immediately while hot.
