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.
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.

Olive Garden Alfredo Sauce
Ingredients
- 6 Tablespoons butter, high quality
- 1 Tablespoon garlic, minced
- 2 Tablespoons all-purpose flour
- 1.5 cups heavy cream
- 1.5 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. 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.
- Slowly sprinkle in the cheeses, continuing to whisk.
- Drain the pasta and carefully mix it into the sauce until well incorporated. The pasta will absorb the sauce an it will get thicker still.
- Garnish with chopped parsley, and serve!

Notes
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.

This was a great recipe, never thought flour would work. But oh my gosh it was delicious. Thank you for this post.
Hey Valerie! I’m SO happy that you enjoyed the Alfredo Sauce! It’s amazing how easy it is, isn’t it? It’s the only Alfredo Sauce I’ll make! 🙂 I’m glad that you enjoyed it too! Have a wonderful day and thank you so much for taking the time to leave a comment and a rating! -Stephanie
Yummy; nice and creamy – family loved it
So happy to hear that Christy! THANK YOU so much for taking the time to leave a rating too, you’re the best!!
This is by far the best Alfredo I’ve ever made! Thank you for sharing this recipe. I will definitely be making this again!
Hey Tameka! That’s SO great to hear! I’ll never make another Alfredo recipe either, this is the one! THANK YOU for taking the time to leave a review, you’re the best! Take care my friend! -Stephanie
This was excellent, I used about a cup less cheese than the recipe and may even cut the total amount in half. The flavor was great but I just prefer mine less cheesy. I added some grilled chicken and my family was saying that broccoli would be good as well. (I don’t like broccoli but would do for the fam)! 🙂
Hey Tammy! I’m so glad that you enjoyed it and were able to make modifications to suit your taste! 🙂 I LOVE adding chicken to this, and love the broccoli idea too! Hey- it’s a plus that your family will eat broccoli, haha. I can’t always say the same. Thank you for taking the time to leave a rating, I REALLY appreciate it! -Stephanie
Hey! Making this tonight and I have a quick question! I have half and half- do I just combine 3 cups? For the 1.5 milk and 1.5 cream?
Hey Bree!! Exactly, yes thats perfect!
The recipe is pretty good. Personally, I found it to be too thin. I changed the flour to 3 tbsp. and used 3 cups of heavy whipping cream instead of half milk half cream. Be sure to whisk the butter/ flour/ milk for 10 minutes minimum before adding the cheese or it will thin out. Don’t be shy with the salt.
The sauce tastes best if you let it sit, either for a day in the fridge and serve over fresh pasta or 30 minutes with no heat if you’re in a hurry. Overall, a good first Alfredo sauce but, don’t hesitate to make it your own!
Thank you! I found it too thin as well. Your post made me hopeful I can save it by keeping in the fridge a day or two.
Hello, I can’t wait to try this recipe! I’ve failed many times when making homemade Alfredo. It’s always clumpy or glue-like, tastes too much like flour- I always follow the recipes I find, but I’ve always had the same results. Can you give me any guidance on this before I try this recipe?? Thanks!
Hey Katie!! Here are my tips:
1. Prepare all of your ingredients ahead of time so that they’re ready to go. This sauce takes NO time to make.
2. Since the sauce takes no time to make, boil your pasta water ahead of time. When you start making your sauce, toss in the pasta. Aim to have them both ready around the same time.
3. Note that Alfredo sauce isn’t meant to be super thick, although it will thicken upon standing. It’ll be even thicker once you add the pasta.
4. BIG tip here: Add the cheese to the sauce GRADUALLY and over LOW heat, stir constantly and remove from heat immediately. That’ll ensure the sauce is smooth. Cheese clumps up when it’s added to a super hot base.
5. Make sure your cheese is grated at home and not pre-shredded or grated.
If you follow those tips, you’ll be golden!
Wonderful recipe…probably the best alfredo sauce I’ve made at home. The only difference was that I added Chicken and I don’t eat carbs at night so I had Zoodles.
So happy to hear that Lelea! And I love that you added chicken and had zoodles! Yum! Thank you so much for taking the time to leave a review! 😁 -Stephanie
