I know it’s a restaurant chain, but honestly, Olive Garden’s Alfredo Sauce recipe is just perfect in my book. Hands-down. Chain or no chain, I love it.

(And you won’t believe how easy it is to make at home!)

PRO Tips For Making Olive Garden Alfredo Sauce:

-Olive Garden’s Alfredo Sauce recipe is made with Parmesan and Romano Cheeses, however you can also incorporate Mozzarella, Gruyere, Gouda, or Asiago. You can also just use Parmesan.

-You can use half and half instead of half heavy cream/half milk.

If you only have evaporated milk, just use half the amount of milk and replace the other half with water. You won’t compromise flavor or consistency by doing this in creamy sauces like this one.

-You can even experiment with different pastas. I like fettuccine because the noodles soak up that thick sauce well, and Tortellini Alfredo with Broccoli is delicious as well!

How to Make Alfredo Sauce:

Melt the butter. Add the garlic and cook for 1 minute.

Whisk in the flour. Add heavy cream and milk. Gradually whisk in the cheese.

Final steps in making Alfredo sauce by adding cheese to a pot and stirring it into the sauce

Add cooked Fettuccine. Sauce will continue to thicken upon standing.

Tip: I like to use 3/4 lb. of fettuccine for saucier pasta, but this recipe will satisfy a full pound as well.

Tips for Extra-Creamy Sauce

  • Use blocks of (high-quality) cheese and shred it yourself for extra creamy, non-grainy results.
  • Let the cheese come down to room temperature before adding it to the sauce.
  • Sprinkle in the cheese gradually, the sauce should be warm but not too hot.
  • High-quality butter is important. You can also make your own butter.

Note: Bagged shredded cheese has cellulose added to it to prevent the cheese from sticking together in the bag. Cellulose repels moisture, which makes it melt poorly in comparison to shredding the cheese yourself.

⭐Pro Tip:

  • Alfredo sauce continues to thicken upon standing, and thickens even more when it’s added to pasta.
  • Refrain from adding additional cheese to thicken it up, the consistency is generally on the thinner side.

Making Alfredo Sauce Ahead of Time

  • Alfredo sauce is a convenient make-ahead and freezable sauce. Unlike some other cheese sauces, the flour in this recipe helps it to maintain it’s consistency when cooled and reheated.
  • It can be stored in the refrigerator for up to 3 days.
  • It can also be frozen and is best if used within 1-2 months.

How to Reheat Fettuccine Alfredo

  • For best results, reheat cold fettuccine in a double boiler with the lid on. The consistency, texture, and flavor is much better than microwaving. (Here’s how to make your own double boiler.)
  • Frozen Alfredo sauce should be thawed overnight in the fridge before reheating.
  • It’s always best to freeze sauce by itself and boil fresh pasta before serving.
  • If the sauce is too thick when reheated, add a splash of milk or chicken broth to thin it out.

  • Whisk in the flour. Gradually add the heavy cream, then the milk, whisking constantly.
  • Reduce the heat to low once the sauce begins to bubble. It will continue to thicken as it simmers.

Notes

Note: You may be tempted to add more cheese to thicken to sauce, but it continues to thicken upon standing and even when added to the pasta.
Alfredo sauce is generally thinner than you may think and thickening it further may make it too rich.

For Saucier Pasta: Use 3/4 lb. pasta instead of a full pound.

How to Reheat Alfredo Sauce

  • Alfredo sauce will thicken up and harden as it cools, but can be easily microwaved or slowly reheated on the stove top. You'll see it begin to take on more of it's original form as it reheats. 
  • Frozen Alfredo sauce should be thawed overnight in the fridge before heating.
  • If the sauce is too thick when reheated, add a splash of milk or chicken broth to thin it out.

  1. Perfect.  I did a Cajun seasoned mahi mahi to lay on top of the fettuccine, and I added a 1/4 tsp of Cajun seasoning to the sauce, 3 egg yolks, and 2 slices of white American cheese. It was fabulous.

  2. Tasted excellent, was really quick to make and was exactly what I needed. I’m living overseas and missing familiar tastes like these. Make sure you pick a big enough pan! It was too late by the time I realized I was in trouble… 🙂

    • Hey Nicole, I am so happy to hear that you enjoyed this recipe! Thank you so much for taking the time to leave this review, I really appreciate it! -Stephanie

  3. Tastes exactly like Olive Garden.  We loved it!

  4. If you dont have heavy cream, can you just use milk instead?

  5. This was awesome, there was another variant that I was using that disappeared from the internet. but this is just as good.

    This recipe uses 1.5 of HC , and .5 of milk, where as the other used 2 cups of HC, no milk.

    • I’m happy you were able to find this recipe and enjoyed it! I’ve been an Olive Garden Alfredo fan for so long so I was so happy when I learned how to make it at home! Thanks so much for the review!😃

  6. Made it tonight and it was absolutely delicious. This is the Keeper!

  7. i used block cheese and i got land o lakes butter but i still got the sandy gritty texture in the sauce. it was still delicious but i wanna perfect it now

    • Hey James! That is the result of the heat being too high, which causes the dairy in the cheese to separate and leaves you with a gritty consistency. Make sure the heat is SUPER low next time and give the base a chance to cool before you gradually sprinkle in the cheese. Remove it from the heat as soon as the cheese is added. You’ll be a pro in no time!

  8. Great recipe 👍👍

  9. I’ve made this twice!  It’s sooo good!  The second time, I sautéed shrimp to go on it. You can’t find it as good in a restaurant!  

  10. this was a big hit for my family! It was delicious!
