Why You Will like This Recipe

Let's face it. Nothing quite compares to heavy cream which is used as the main ingredient in Alfredo. Heavy cream can make anything bad taste good, not to mention butter and bacon.

I think that Alfredo sauce is probably one of the hardest dishes to make lighter but this recipe does a pretty good job with recreating it. Instead of heavy cream milk and reduced fat cream cheese is used. Parmesan is another main ingredient in Alfredo sauce which is also a must for a dish. No substitutions for that!

Ingredients for Fettuccine Alfredo

  • Unsalted butter - is the most commonly used type of butter in baking, as it allows for more control over the amount of salt in the recipe.
  • Garlic, minced - Chopped fresh garlic can take some time to chop so I often always use the freshly minced garlic that comes already made in a jar.
  • Lemon zest - This adds a nice burst of citrus flavor to the marinade to help enhance the choice of protein. Use freshly squeezed over bottled juice.
  • All-purpose flour - is a type of wheat flour that is commonly used in cooking and baking. It is versatile and can be used for a variety of recipes, including bread, cakes, cookies, and pastries.
  • Low-fat (1%) milk - can sub almond milk if you're allergic to milk
  • Neufchtel or low-fat cream cheese - I like to use Reduced-Fat Cheese because it has a lower calorie count and less saturated fat than regular cheese, but it may also have a different taste and texture. It also helps with keeping the calorie count pretty low for this recipe.
  • Parmesan cheese - is a hard, granular cheese that originated in Italy. It is typically made from cow's milk and has a sharp, nutty flavor. Parmesan cheese is often grated and used as a topping for pasta dishes, salads, and other foods.
  • Fresh parsley (optional)
  • Fettuccine - any pasta shape will work with this

    I updated the recipe to include the flour and parsley. I don't add salt and pepper to a recipe in the builder because those two ingredients never change the points. You can also save it and edit it yourself. FYI.

  2. Miranda says

    When I click the link to see this in my WW recipe builder, it’s missing ingredients! The salt, pepper, parsley, and flour don’t appear in my recipe builder. Broken. Thank you.

  3. Christine says

    This is a great recipe and we all loved it. I may have added more cheese but so worth it.

  4. Jeffrey Castle says

    Excellent recipe and I was able to make the sauce with much lower calories and fat content. I began with two tbsps of yogurt butter spread (Brummel and Brown) which is more than the recipe calls. Anyone with knowledge of creating a roux knows to begin with equal amounts of fat and flour. Instead of milk, I used fat free evaporated milk and fat free cream cheese. I followed the recipe from that point forward to the letter and go a flavorful, low calorie, creamy sauce that I put over brown rice spaghetti, topped with roasted squash, carrots, and onions, and topped with a grilled chicken breast. SO FULFILLING...

  5. Lisa says

    Delicious.
