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 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. Otherwise the dairy will separate and the consistency will be grainy.
  • High-quality butter is important. I like Land O’ Lakes brand.

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.

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 Alfredo Sauce

  • Alfredo sauce will thicken up and harden as it cools, but can be easily microwaved or slowly reheated on the stove top. Reheating in a makeshift double boiler is the best reheating method to restore it back to it’s original form.  (Either by itself or when combined with pasta.)
  • 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.

Make Olive Garden's Alfredo Sauce Recipe at home in just 20 minutes! Pair it with Fettuccine for an easy dinner idea the whole family will love!

Ingredients

  • 6 Tablespoons salted butter, high quality
  • 1 Tablespoon garlic, minced
  • 2 Tablespoons all-purpose flour
  • 1 ½ cups heavy cream
  • 1 ½ cups milk, any kind
  • ½ cup Parmesan cheese, grated and at room temperature
  • ½ cup Romano cheese, grated and at room temperature
  • Salt and black pepper, to taste
  • 1 lb. Fettuccine
  • Parsley, to garnish

Instructions

  • Boil the fettuccine according to package instructions. As the water preheats, begin the sauce.
  • Melt the butter in a large saucepan over medium heat. Add the garlic and cook for one minute.
  • Whisk in the flour and cook for 1 minute, stirring continuously.
  • Add the heavy cream in splashes, stirring continuously. Add the milk in the same manner.
  • Bring to a gentle bubble, then reduce heat to low to bubble. It will continue to thicken as it simmers.
  • Slowly stir in the cheese. Taste and season with salt/pepper if desired.
  • Drain the pasta and carefully mix it into the sauce until well incorporated. The pasta will absorb the sauce and it will continue to thicken.
  • Garnish with chopped parsley and serve!

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.

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

Pro Tips for Reheating:

  • Alfredo sauce will thicken up and harden as it cools, but can be easily microwaved or slowly reheated on the stove top. Reheating in a makeshift double boiler is the best reheating method to restore it back to it's original form. 
  • 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. I just made this tonight because I had heavy cream that needed to be used and a huge wedge of pecorino romano from Costco. I used garlic powder instead of fresh and this turned out amazing! Thank you

  2. I just made this for my fussy family and I added cooked chicken. Well, believe me they love, love, loved it. It was so tasty and much much better than a jar. Thank you for your recipe. 

    • Yayyyy! Sounds like you nailed it Ann! No better feeling than getting great compliments from family members. I’m so happy your family enjoyed it. Thanks so much for the great review!😍

  3. Rich, creamy, delicious, and tastes pretty close to Olive Garden’s Alfredo sauce for a fraction of the price! Nothing better than leftovers for the next few days too.

  4. Love this recipe!! Only thing diff is i use bow tie noodles. Thank you for sharing.

  5. I’ve had made this alfredo sauce recipe probably 20 times since I’ve stumbled upon this recipe on Pinterest. It’s a favorite in our family. Thanks a million! 😁

  6. I have always been a fan of red sauce. This recipe is simple and delicious.

  7. Great recipe!! I added salt and pepper to the sauce + a touch of Italian seasoning since I didn’t have any parsley. Also added seared chicken. Too good! 

  8. I moved back to the UK and there are no Olive Gardens here.  I came across your recipe and thought I’d give it a go.  I had to substitute fettuccine with Tagliatelle and Romano cheese with more Parmesan.  I also used Kerrygold butter in place of Land o’ Lakes.  It turned out perfect and tasted exactly like Olive Garden.  I’ll be making it again when I have friends over for Boxing Day.  Thank you.

    • I am so happy to hear that you enjoyed this recipe Lindsey, and nicely done with the substitutions based on what was available to you! Thank you for taking the time to leave this review, I really appreciate it! -Stephanie

  9. What kind of “high quality” ingredients do you use? Also they don’t have that cheese at my grocery stores. Is Mozerella okay? Mine didnt turn out good but it is probably because I accidentally burned my butter while melting 😩

    • Hi Tyrah, I suggest Land O’ Lakes butter in the blog post but if you don’t have Parmesan or Romano cheese available to you at this time, then I don’t suggest you use mozzarella instead.

  10. This was my first time making Alfredo sauce. It turned out perfect 😁 tasted just like olive gardens. We will make this again.
