Notes

  • *Processed Cheese: keeps alfredo sauce super creamy even after sitting! It's the secret ingredient to making ultra-creamy alfredo sauce without detecting it! Use Velveeta or American cheese slices.   
  • To make dry alfredo mix: stir the dry ingredients (use the unrefrigerated parmesan cheese) and keep in an airtight container. Use when needed with 3 cups of heavy cream. 
  • To Reheat: Alfredo Sauce reheats well only once after making. Avoid reheating multiple times as the cream separates. 
  • Store: prepared sauce up to 5-6 days in the fridge.
  • To freeze alfredo sauce: Place cooled alfredo sauce into freezer bags and keep frozen for up to 3 months.
  • To make ahead: cool and store sauce in the fridge. Scoop sauce on top of a casserole and stir after baking or reheat on stove and ladle over hot pasta. 
  • Yields: approx. 3 cups of sauce. Serve with every 1 pound of pasta. 
*Heating alfredo sauce more than once after it has cooked will lose its creamy texture and look more greasy.
