  2. Serve: Remove from the oven and let it cool for a few minutes before serving.

Cooking Notes and Variations

Cooking Notes:

  • Chicken: For a richer flavor, use grilled chicken breasts. Rotisserie chicken is a great time-saver and adds a different depth of flavor.
  • Pasta: Linguine is recommended, but you can substitute with other pasta shapes like fettuccine, penne, or rigatoni.
  • Vegetables: Feel free to add or substitute other vegetables such as bell peppers, zucchini, or artichoke hearts.


  • Keto Version: Replace the linguine with zucchini noodles or shirataki noodles. Use heavy cream and cheese, but ensure they are full-fat and keto-friendly.
  • Gluten-Free Version: Use gluten-free pasta and ensure the cornstarch and other ingredients are certified gluten-free.
  • Vegetarian Version: Omit the chicken and add more vegetables such as bell peppers, zucchini, and broccoli. Use vegetable broth instead of chicken broth.
