Ingredients Equipment Method Notes

Ingredients
  

  • 4 pieces boneless, skinless chicken breasts cut into bite-sized pieces
  • 3 cloves garlic minced
  • 2 cups chicken broth low-sodium preferred
  • 1 cup heavy cream or substitute with half-and-half for lighter version
  • ½ cup Parmesan cheese freshly grated
  • 12 oz pasta fettuccine or penne, cooked al dente
  • 1 tablespoon butter unsalted
  • ½ teaspoon nutmeg optional
  • to taste salt and black pepper adjust seasonings after cooking

Equipment

  • Slow cooker
  • Chef’s knife

Method
 

  1. Gather your slow cooker, a sharp chef's knife, and a cutting board. Start by cutting the chicken breasts into bite-sized pieces and mincing the garlic. Have everything ready to go.
  2. Place the chicken pieces in the bottom of the slow cooker. Sprinkle the minced garlic over the chicken, then pour in the chicken broth and heavy cream. This creates a flavorful, creamy base for the dish.
  3. Stir in the grated Parmesan cheese, sprinkle with nutmeg if using, and add a pinch of salt and black pepper. Cover the slow cooker and cook on low for about 4 hours, until the chicken is tender and the sauce is bubbling gently.
  4. Once cooked, prepare your pasta according to package instructions until al dente. Drain and set aside.
  5. Add the cooked pasta into the slow cooker with the chicken and sauce. Stir well to coat the pasta evenly with the creamy sauce. Turn the slow cooker to warm and let everything meld together for about 5 minutes.
  6. Taste the dish and adjust the seasoning with more salt and pepper if needed. If the sauce is too thick, stir in a splash of broth or cream to loosen it up. Finish by stirring in the butter to add extra richness.
  7. Serve the chicken Alfredo hot, garnished with additional Parmesan and freshly chopped parsley if desired. The sauce should be silky and thick, clinging to each pasta and chicken piece, with a fragrant aroma of garlic and cheese. Enjoy your cozy, creamy dinner!

Notes

For a lighter version, substitute heavy cream with half-and-half or milk. You can also add some sautéed spinach or mushrooms for extra flavor and nutrition.
