Equipment

  • 1 large heavy-bottomed pot or Dutch oven
  • 1 medium bowl

Ingredients
  

  • 2 tablespoons olive oil divided
  • 1 ½ pounds boneless skinless chicken breasts or thighs, cut into 1-inch pieces
  • 2 tablespoons Cajun seasoning divided
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 2 tablespoons unsalted butter
  • 1 medium yellow onion finely diced
  • 1 red bell pepper finely diced
  • 4 cloves garlic minced
  • 1 teaspoon dried oregano
  • ½ teaspoon dried thyme
  • 1 teaspoon smoked paprika optional
  • 2 cups uncooked orzo pasta
  • 4 cups low-sodium chicken broth
  • 1 ½ cups heavy cream
  • 1 cup freshly grated Parmesan cheese plus more for serving
  • Fresh parsley chopped (for garnish)

Instructions
 

  • Pat chicken dry and cut into 1-inch pieces. Toss with 1 tablespoon olive oil, 1 tablespoon Cajun seasoning, salt, and pepper until evenly coated.
  • Heat remaining 1 tablespoon olive oil in a large pot or Dutch oven over medium-high heat. Sear chicken pieces without overcrowding, about 3-4 minutes per side, until golden brown. Work in batches if needed. Remove chicken and set aside.
  • Reduce heat to medium. Add butter to the pot and melt, scraping up browned bits. Sauté diced onion and red bell pepper for 5-7 minutes until softened and translucent.
  • Add minced garlic, dried oregano, thyme, and smoked paprika if using. Cook, stirring constantly, for 1 minute until fragrant.
  • Stir in uncooked orzo pasta and toast lightly for about 30 seconds to 1 minute.
  • Pour in chicken broth, stirring well and scraping up any remaining browned bits. Bring to a gentle simmer.
  • Reduce heat to low, cover, and cook orzo for 10-12 minutes, stirring occasionally, until liquid is mostly absorbed and orzo is tender but firm.
  • Remove pot from heat. Stir in heavy cream until well combined and creamy.
  • Gradually add grated Parmesan cheese, stirring until melted and sauce is smooth and velvety.
  • Return seared chicken to the pot and gently fold it into the orzo Alfredo mixture to warm through.
  • Serve immediately, garnished with chopped fresh parsley and extra Parmesan if desired.

Notes

  • Use freshly grated Parmesan cheese for a creamy, smooth sauce.
  • Adjust Cajun seasoning to control spiciness.
  • Store leftovers covered in the fridge for up to 3 days.
  • Reheat gently to avoid sauce separation.
