Alfredo Sauce is a fast and easy creamy sauce made with a simple combination of heavy whipping cream, Parmesan cheese, butter, flour and garlic. This recipe for Homemade Alfredo Sauce is my family’s absolute favorite. Alfredo Sauce is a classic creamy pasta sauce that only takes about 15 minutes to make and features lots of Parmesan cheese.
The best sauce for any of your favorite pasta, Chicken Alfredo, Shrimp Alfredo, poured over broccoli, to dip breadsticks, and many other dishes.
HOMEMADE ALFREDO SAUCE
This is my family’s absolute favorite sauce to have with pasta, chicken, shrimp, and vegetables. (I’ve even make some Alfredo for a quick lunch to dip some bread stick into.) Like many other classic sauces, you can use Alfredo sauce with so many different dishes so the whole jar of sauce can last through several different dinners.
After many disappointing tastings of jarred sauces, I had to come up with my own recipe that my family will actually enjoy. My Alfredo Sauce has taken me years to perfect. I’ve tried a few different variation and this one is the best by far. I like using fresh grated Parmesan cheese and dry Parmesan. The combination of the two makes perfect texture and flavor.
Among all the classic sauces, Alfredo is my favorite one because it’s so creamy, cheesy, and comforting. It’s perfect with chicken, seafood, vegetable or to dip some bread sticks in it. Yes, this sauce can even be served as an appetizer or a dip!
ALFREDO SAUCE INGREDIENTS
Heavy whipping cream – for the rich and creamy Alfredo, it’s best to use heavy whipping cream.
Butter – use unsalted butter and add salt to the sauce according to your preference.
Sour cream – the small amount will add some flavor balance to the cream with it’s tartness.
Flour – just a little bit to thicken the sauce.
Garlic – there is just one clove but it will give a very pleasant flavor to the sauce without overpowering it.
Parmesan cheese – a combination of fresh grated and pre-grated is perfect for the flavors and the texture because fresh grated Parmesan cheese melts better but pre-grated Parmesan that you can buy does not.
Use salt and pepper to taste.
HOW TO MAKE IT
This sauce is a very easy sauce to make and will only take about 15 minutes and you can make it while pasta and meats are cooking. It’s always best to prepare and measure your ingredients ahead of time, especially in a fast recipe like this one.
Use a medium sauce pot to prepare the Alfredo Sauce. Melt butter over medium heat and once butter is melted, add pressed garlic. Cook garlic until it’s fragrant and sprinkle flour over it. Stir and then slowly pour in heavy whipping cream.
Gently stir the mixture together and let it heat through. (Don’t let it boil!) Once heavy cream is hot, whisk in sour cream, Parmesan cheeses, salt, and pepper. Lower heat to medium-low and gently stir until grated cheese starts to melt.
Keep cooking over medium-low heat for about 5 minutes, stirring often. Once sauce is ready mix it with cooked pasta.
IS ALFREDO SAUCE GLUTEN FREE?
This Alfredo Sauce recipe is not gluten free BUT it is easily make gluten free by using gluten free all purpose flour. There is not much flour that goes into the sauce because the sauce gets most of its thick texture from Parmesan cheese and sour cream. The combination of freshly grated Parmesan cheese and some dry Parmesan cheese thickens the sauce nicely where only a small amount of flour is needed.
STORING INSTRUCTIONS
Store Alfredo sauce in a glass jar with a lid in the refrigerator for 3-5 days.
REHEATING INSTRUCTIONS
I don’t really recommend reheating Alfredo Sauce in a microwave because it separates easily if it is overheated. The key to reheating Alfredo sauce is low and slow.
If you wish to try and reheat it in a microwave, use lower power setting and heat it up for 30 seconds at a time, stirring in between.
The better way to reheat it though is in a small sauce pot, over medium-low heat. Let it warm up slowly, while stirring often.
One more way to reheat the sauce is to mix cold sauce with hot, freshly cooked pasta. As soon as you drain the boiling water off pasta, add it back to the empty pot and add cold sauce. Mix it together and let hot pasta heat up the sauce.

I just loved the Alfredo sauce, as did my children. I have been on your site for hours at a time today. I have been looking for a delicious peanut butter cupcake recipe along with a peanut butter frosting, can you help me out…
Gina Gutierrez says
Obviously it has to go in the fridge, right? I would love to give this as a Christmas gift. What do you suggest? If you have any suggestions! I like making food gifts!
Deb says
I am cooking for a wedding. Having both red sauce and Alfredo. Guest list is 100 so I am trying to prepare as much as possible in advance. Can this be made 2 days in advance and warmed up or will it separate?
Thank you
lyuba says
Hi Deb!
You know, I’ve had it separate on me when I reheated it in the microwave before. You can test it out and make a small batch and then reheat it the next day in a pot. May be if it’s reheated slower, in a pot, it will hold together.
Best of luck with the catering!

When you say fresh grated Parmesan and dry Parmesan, what do you mean by dry? Is that the powdered graded cheese you get in the canister? Or is it just grated Parmesan that you buy in the tub by the dairy aisle I understand grated Parmesan fresh off the block. Just don’t know what the dry one is. Thank you. I can’t wait to try your recipe.
Elizabeth DelPidio says
I just couldn’t wait to make this and taste it. I used all fresh grated cheese I had previously grated on a microplane. And I halved recipe only because I only needed 1 cup for the tortellini. It tastes awesome and amazing. I never knew how quick and easy it is to make this sauce. And I had all the ingredients at the ready. I won’t be using the jarred sauce anymore.
LyubaB says
Hi, Elizabeth! Yes, Parmesan is the cheese in the container, but I am glad it came out good and you liked it! 🙂
Jess says

LyubaB says
Thanks for letting me know, I am so glad you liked it!
Kathy says
Really good. Great recipe! Made a super small change. My family likes a little heat added. crushed red pepper flake. I have never used sour cream in Alfredo Sauce. Really glad I found your recipe.
LyubaB says
Thank you, Kathy! I am so glad you like it!
Aleisa says
Hi! I don’t have any fresh Parmesan. Is it possible to just use a full cup of dry Parmesan for this recipe?
LyubaB says
Hi Aleisa,
I do not recommend it because dry parm does not melt as well or have the same smoothness so it’s really best to get a block and grate it.
Sharon S says
Do you have to use heavy cream? Has any one tried it with 1/2 & 1/2 or whole milk? Heart condition in the family
Diane says
Just found your alfredo sauce recipe. I was wondering can we double or triple this recipe? My family are big pasta eaters so I need tio make sure have enough….love all you recipes. Never disappointed.
LyubaB says
Sure, you can double or triple it by using 2 or 3x as much as the recipe calls for and cooking it the same way. I hope you enjoy it!
Lesli Holt says
