Season the chicken breasts with Cajun seasoning, ensuring they are evenly coated.
In a large skillet, heat olive oil over medium-high heat. Once hot, add the seasoned chicken and cook for about 5-7 minutes on each side, or until fully cooked and browned. Remove from skillet and let rest for 5 minutes before slicing into strips.
In the same skillet, add minced garlic and sauté for about 1 minute until fragrant.
Pour in the chicken broth and bring it to a simmer. Stir in the orzo and cook according to package instructions, usually around 8-10 minutes, until al dente.
Lower the heat and stir in the heavy cream and Parmesan cheese. Mix until the cheese is melted and the sauce is smooth.
Add the chopped spinach and sliced chicken back into the skillet, mixing everything together. Season with salt and pepper to taste.
Cook for an additional 2-3 minutes until the spinach has wilted.
Remove from heat and let rest for a minute before serving.
Notes
Serve the dish in shallow bowls, garnished with fresh parsley and a sprinkle of extra Parmesan cheese for an added touch.
