Combine chicken breasts with 1.5 tbsp Cajun seasoning mix and 2 tsp olive oil. Cover and refrigerate for at least a few hours or overnight for maximum flavor.
Cook the Chicken:
Heat 25 g butter in a skillet over medium-high heat. Cook chicken until golden brown and crispy on the outside. Remove and let rest for a few minutes before slicing into strips.
Prepare the Cajun Rice:
In the same skillet, sauté the chopped red onion and garlic until fragrant. Add ½ tbsp Cajun seasoning and stir in the cooked rice. Toss until well coated with the spices.
Make the Creamy Sauce:
Lower heat to medium-low. Melt 15 g butter in a pan, add ½ tbsp Cajun seasoning, and whisk in the milk. Stir in cream cheese and Parmesan until smooth and creamy.
Assemble the Dish:
Layer the Cajun rice on a plate, top with sliced chicken, and drizzle the creamy sauce over the top. Garnish with chopped parsley and serve immediately.
