Ingredients

Instructions

  1. Step 1: Toss 2 boneless skinless chicken breasts cut into 1-inch pieces with 2 tbsp Cajun seasoning evenly.
  2. Step 2: Heat 2 tbsp olive oil in a large deep skillet or Dutch oven over medium-high heat. Add the chicken and cook for 5-6 minutes, stirring occasionally, until browned and cooked through. Remove chicken and set aside.
  3. Step 3: In the same pot, add 4 minced garlic cloves and sauté for 30 seconds until fragrant.
  4. Step 4: Add 12 oz penne pasta, 3 cups chicken broth, 1 tsp salt, and 1/2 tsp black pepper. Bring to a boil, then reduce heat to medium-low and simmer uncovered for 12-15 minutes, stirring occasionally until pasta is tender and liquid is mostly absorbed.
  5. Step 5: Stir in 1 cup heavy cream, 1 cup freshly grated Parmesan cheese, and 4 cups fresh spinach. Cook for 2-3 minutes until spinach wilts and sauce thickens.
  6. Step 6: Return the cooked Cajun chicken to the pot, stir to combine, and heat through for 1-2 minutes before serving.
