01 - Rinse 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, 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. Rub with 1 tablespoon Cajun seasoning, smoked paprika, black pepper, and 1/2 tsp salt, ensuring even coating on all sides.
03 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add seasoned chicken in a single layer, cooking without disturbing for 3-4 minutes to develop a golden crust. Flip and continue cooking until browned and cooked through, approximately 5-7 minutes total. Transfer chicken to a plate and set aside.
04 - In the same skillet, add diced red onion and bell peppers. Sauté for 3-4 minutes until vegetables begin to soften and edges char slightly. 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 melted.
06 - Return browned chicken to the skillet along with any accumulated juices. Add remaining 1/2 tablespoon Cajun seasoning and grated Parmesan cheese. Stir gently until sauce coats everything evenly. Simmer for 3-4 minutes until sauce thickens slightly and chicken is heated through.
07 - Divide fluffy white rice evenly among four serving bowls. Top generously with creamy Cajun chicken and vegetable mixture, ensuring plenty of sauce reaches the rice. Garnish with fresh sliced green onions and chopped parsley. Serve immediately while hot.
