What is Alfredo Sauce?

Unlike traditional pasta sauce, Alfredo sauce is not made with any tomatoes. This is a creamy white sauce that is made with a combination of parmesan cheese, butter and cream.

It’s best served over your favorite type of noodles and goes great with chicken or fish. It’s often used in Italian recipes.

I love alfredo sauce and it’s easier to make at home than you think.


Ingredients to make homemade Alfredo sauce - unsalted butter, half and half, minced garlic, parmesan cheese, nutmeg, salt and pepper
  • Unsalted Butter
  • Half and Half
  • Minced Garlic
  • Freshly grated parmesan cheese
  • A pinch of freshly grated nutmeg
  • Salt and Pepper, to taste

Variation Ideas

  • For the Half and Half – You can also use heavy whipping cream or milk in this recipe instead of half and half. If you use milk, the sauce may not be as creamy but will still taste great.
  • For the Parmesan Cheese – You can use grated Romano cheese or Asiago Cheese in this recipe instead of parmesan cheese to change up the flavor.
  • For the Minced Garlic – You can use garlic salt or a small amount of garlic powder instead of the minced garlic if you prefer.
  • Add in Cream Cheese – For more of a cheesy sauce, stir in 4-8 ounces of cream cheese until melted and well combined.
  • Seasoning – Feel free to add in Italian Seasoning for a delicious option and flavor.
  • Veggies – Vegetables can be added into the sauce to serve over your grilled chicken or ground beef pasta dishes. We love slice mushrooms, chopped onions, or bell peppers.

Recipe Tips

  • Adding in Half and Half – Gradually add in the half and half so that it gets combined well with the melted butter.
  • Whisk Ingredients – Use a whisk instead of a spatula or spoon when mixing. This will make sure that the sauce is creamy and smooth. Make sure to check out all our favorite kitchen tools.
  • Heating Sauce – Make sure to not over heat this sauce as it will cause the sauce to curdle. I always remove the pan from the heat before stirring in the parmesan cheese to prevent it from burning or overheating.
  • Parmesan Cheese – Make sure to use freshly grated parmesan cheese instead of the pre-shredded option. The pre-shredded ones are coated with starch that cause it not to melt smoothly.

How to Thicken the Sauce:

If your sauce is not as thick as you prefer, here are a few options to thicken your sauce.

  • Simmer the sauce over low heat for 3-4 minutes and this will thicken sauce. Make sure to watch the sauce closely so that the sauce does not burn. Also, whisk the sauce constantly while reheating so that it doesn’t burn.
  • You can also stir in some cornstarch, arrowroot or flour to thicken the sauce. Stir 2 tablespoons of cornstarch, arrowroot or flour with approximately ¼ cup cold water. Then stir this mixture into the Alfredo sauce and heat for a few minutes to thicken the sauce.
  • Also, add a small amount of cream cheese to the sauce will help thicken it as well. Diced up the cream cheese and whisk it into the sauce until it’s fully melted.
  • You can also add in m ore parmesan cheese. Heat until it’s melted and then thickness that you prefer.

  1. Gail B. says:

    5 stars
    Love this alfredo sauce- super easy to make, and great over cauliflower and broccoli as an alternative to pasta if you want. I’ve never seen fresh nutmeg in the store, so I use regular dry nutmeg.

  2. Carrie says:

    Yes, you can use jarred.

  3. Carrie says:

    Half and Half is a diary product generally in the diary aisle. If you cannot find it in your area, you can use heavy whipping cream instead. Thank you.

  4. Katriona Harrington says:

    Hi, without sounding stupid but in the recipe you have 1 cup of half and half what is this

  5. Glenda says:

    I have never seen nutmeg to grate, just jarred. Would that be ok to use?7
