01 - Rinse rice under cold water until water runs clear. Combine with 2 cups water and 1/2 tsp salt in a saucepan. Bring to a boil over high heat, then reduce heat 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. Season thoroughly with 1 tbsp Cajun seasoning, smoked paprika, black pepper, and salt, ensuring all pieces are evenly coated.
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. Transfer chicken to a plate and set aside.
04 - In the same skillet, add diced onion and bell peppers. Sauté for 3-4 minutes until softened and lightly charred. Add minced garlic and cook for 1 minute until fragrant, stirring constantly to prevent burning.
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 cream cheese, continuing to stir until completely smooth and incorporated.
06 - Return chicken to the skillet along with any accumulated juices. Add remaining 1/2 tbsp Cajun seasoning and grated Parmesan. Stir gently until sauce thickens and coats the chicken evenly. Simmer for 3-4 minutes, adjusting consistency with additional broth if needed.
07 - Divide fluffy rice among four serving bowls. Top generously with creamy Cajun chicken mixture and sauce. Garnish with sliced green onions and chopped parsley. Serve immediately while hot.
