Notes

Nutrition Information doesn't include potatoes or pasta/noodle base.
Tips and Substitution
  • I wouldn’t recommend substituting milk for half and half as it tends to curdle.
  • For a thicker, smoother texture, you can substitute the half and half and cornstarch with 1 cup heavy whipping cream.
  • For cream cheese lovers, you can omit the half and half in the beginning step and substitute with 1 cup chicken broth and the cornstarch mixed together. In the final 30 minutes of cooking, add an 8 ounce brick of cream cheese, cut into cubed. Stir the mixture, cover and cook the remaining 30 minutes. Remove the lid and stir until smooth and thickened.
  • Fresh basil in the final step can be substituted with 1 teaspoon fresh basil added in at the beginning before the cook time begins.
  • Fresh garlic can be substituted with ½-1 teaspoon garlic powder.
