Prep Time5 minutes
Cook Time15 minutes
Total Time20 minutes
Servings: 4

Ingredients

  • 2 Tbsp olive oil
  • 1 lb boneless skinless chicken breast, cut into bite-sized chunks
  • 2 tsp Cajun seasoning divided
  • 2 garlic cloves minced
  • 1½ cups chicken broth
  • 1 cup half and half
  • 1 tsp salt
  • 1 tsp black pepper
  • ¼ tsp garlic powder
  • 8 oz fettuccine broken in half
  • ½ cup grated Parmesan cheese

Instructions

  • In a large pot over medium-high heat, warm olive oil.
  • Season chicken with 1 tsp Cajun seasoning; add to pot and cook until no longer pink.
  • Add minced garlic; cook ~1 minute until fragrant.
  • Pour in chicken broth and half and half. Stir in remaining Cajun seasoning, salt, pepper, and garlic powder.
  • Add broken fettuccine, pressing down to submerge. Cover and bring to a boil, then reduce to medium-low. Simmer ~10–12 minutes, stirring occasionally, until pasta is al dente and liquid mostly absorbed.
  • Remove from heat and stir in Parmesan until sauce is creamy and well coated.
  • Serve immediately.

Notes

  • Stir occasionally to prevent pasta stalling or sticking.
  • Adjust Cajun seasoning to your desired spice level.
  • For thicker sauce, use slightly less broth or more Parmesan.
  • Use freshly grated Parmesan for better melt and flavor.
  • Garnish with parsley or extra cheese if desired.
