Ingredients Method Notes

Ingredients
  

Ingredients
  • 1 lb chicken breast, cut into bite-sized pieces
  • 8 oz spaghetti noodles
  • 2 tablespoons olive oil
  • 1 medium onion, diced
  • 3 cloves garlic, minced
  • 1 bell pepper, diced (any color)
  • 2 tablespoons Cajun seasoning
  • 1 cup heavy cream
  • 1 cup chicken broth
  • 1 cup shredded Parmesan cheese
  • Salt and pepper to taste
  • Fresh parsley for garnish

Method
 

Instructions
  1. Cook the Chicken - Heat olive oil in a large pot or Dutch oven over medium-high heat. Season chicken pieces with salt, pepper, and 1 tablespoon of Cajun seasoning. Cook until golden brown and cooked through, about 5-7 minutes. Remove chicken from pot and set aside.
  2. Sauté Vegetables - In the same pot, add onion and bell pepper. Cook until softened, about 3-4 minutes. Add garlic and remaining Cajun seasoning, cooking for another minute until fragrant.
  3. Combine Ingredients - Return the cooked chicken to the pot. Add uncooked spaghetti, chicken broth, and heavy cream. Bring to a simmer, then reduce heat to medium-low. Cover and cook for 12-15 minutes, stirring occasionally, until pasta is al dente and most of the liquid has been absorbed.
  4. Add Cheese and Finish - Stir in Parmesan cheese until melted and creamy. If the sauce seems too thick, add a splash more chicken broth. Taste and adjust seasoning as needed.

Notes

Customize heat level by adjusting Cajun seasoning. Use fresh garlic and high-quality Parmesan for best flavor. Don't overcook pasta - aim for al dente. Dish reheats well and can be stored for up to 3 days.
