Begin by dicing the boneless skinless chicken breasts into bite-sized pieces. Set the chicken aside while you gather your ingredients.

In a large pot, heat a drizzle of olive oil over medium-high heat. Once hot, add the diced chicken and season with Cajun seasoning. Sauté for about 5-7 minutes until golden brown and cooked through.

Stir in the uncooked orzo and the remaining Cajun seasoning. Pour in the chicken broth and heavy cream, mixing well. Bring to a gentle simmer over medium heat.

Reduce heat to medium-low and allow to simmer for about 10-12 minutes, stirring occasionally until the orzo is tender and the sauce thickens.

Remove from heat and stir in the freshly grated Parmesan cheese until melted and incorporated.

Taste and check the consistency. Add a splash of broth or cream if too thick, or let simmer if too thin.
