Ingredients Method Notes

Ingredients
  

Ingredients
  • 1 lb boneless, skinless chicken breasts, cubed
  • 12 oz fettuccine or linguine pasta
  • 4 cups chicken broth
  • 1 cup heavy cream
  • 1 cup grated Parmesan cheese
  • 1 cup shredded mozzarella cheese
  • 3 cloves garlic, minced
  • 1 small onion, diced
  • 2 tbsp butter
  • 1 tsp Italian seasoning
  • ½ tsp black pepper
  • ¼ tsp salt
  • Fresh parsley for garnish

Method
 

Instructions
  1. In a large pot or Dutch oven, melt butter over medium-high heat. Add cubed chicken and cook until golden brown, about 5-7 minutes. Remove chicken and set aside.
  2. In the same pot, add diced onion and cook until softened, about 3 minutes. Add minced garlic and cook for another minute until fragrant.
  3. Pour in chicken broth and bring to a boil. Break pasta in half and add to the boiling broth. Reduce heat to medium and cook pasta according to package directions, stirring occasionally to prevent sticking.
  4. Once pasta is al dente, stir in heavy cream, Parmesan cheese, Italian seasoning, salt, and pepper. Return the cooked chicken to the pot.
  5. Simmer for 2-3 minutes until sauce thickens slightly. Stir in mozzarella cheese until melted and creamy.
  6. Garnish with fresh parsley and serve immediately. The sauce will continue to thicken as it cools.

Notes

For the creamiest Alfredo sauce, use freshly grated Parmesan cheese rather than pre-shredded varieties. Don't rush the sauce thickening process - the pasta starches need time to work their magic. If you prefer a thicker sauce, let it rest for 5 minutes off heat before serving.
