Why This is the Best Alfredo Sauce
You will find countless recipes out there, but I’m confident that you will love this recipe.
Easy to Make
Any kind of pasta dish is a hit in my house, and when I need a quick and easy dinner idea on a busy weeknight, this Alfredo Sauce recipe is one of my favorites. Add some sliced cooked chicken breasts or grilled shrimp and you have a satisfying meal in no time!
Infused Garlic Magic
Experience the magic of infused garlic as it melds with butter over medium-low heat. This slow infusion technique ensures every bite is bursting with flavor.
Watch as the garlic turns a golden brown hue, adding both taste and aesthetics to your delicious sauce.
Perfect Portioning
My recipe yields just the right amount of cheesy cream sauce for a pound of fettuccine noodles, but you can easily double it for larger gatherings.
Versatility
This versatile creamy sauce complements a variety of main dishes and always creates a rich and decadent complete meal. It obviously pairs incredibly well with homemade fresh pasta to make Fettuccine Alfredo.
Ingredients Needed
This extraordinary Alfredo sauce made with just four simple ingredients: unsalted butter, fresh garlic cloves, heavy whipping cream, and authentic parmesan cheese.
Exact quantities are listed in the recipe card below.
Ingredient Substitutions
I have made this recipe countless times and highly encourage you to make it exactly as written, but I know that sometimes recipe alterations are necessary depending on ingredient availability.
Should you need to make modification, these are the recommendations.
- Heavy Cream: While heavy cream is preferred, part-skim milk (less than 1% fat), whole milk (3-4% fat) or half and half (10-12% fat) can be used in place of heavy cream (38-40% fat). The answer is YES, although I don’t recommend it because you will have a thinner sauce due to the lower fat content. If you need to make this substitution and feel that the final sauce is too thin, the sauce can be thickened with sour cream, mascarpone, or cream cheese, if needed.
- Butter: Replace butter with high-quality Extra Virgin Olive Oil.
- Garlic: Fresh garlic is recommended, but frozen or jarred minced garlic will work as well. Garlic powder can be used as a substitute, but it won’t impart the same infused garlic taste.
- Parmesan Cheese: Authentic Italian Alfredo sauce demands Parmigiano Reggiano, but Romano cheese or a parmesan/Romano blend can also work.
How to Make Alfredo Sauce
Step 1: Infuse Garlic in Butter
Begin by melting half a stick of butter over medium-low heat, then add the minced garlic and stir frequently.
This gentle cooking process extracts the full flavor of garlic without any risk of burning. The result is a golden brown infusion that elevates the sauce.
Step 2: Add Heavy Cream
Reserve a portion of the heavy cream for later and let the rest gently simmer in the garlic-infused butter. The creaminess will elevate your sauce to new heights.
Step 3: Stir in Parmesan
Allow the cream and garlic-infused butter mixture to come to a gentle simmer. Increase the heat to medium, if needed. Cook for a few minutes and stir it occasionally.
Remove the sauce from the heat, then stir in grated parmesan cheese and the remaining heavy cream.
This combination creates a silky, rich sauce.
Cooking Tips for Perfect Results
- Quality Ingredients Matter – Choose the finest ingredients for the best results. Fresh, locally-grown garlic and authentic aged parmesan cheese imported from Italy make all the difference if you can use them. Select high-quality butter and heavy cream for a truly rich and buttery sauce.
- Press the Garlic – Maximize the garlic flavor by using a garlic press. Minced garlic exposes more surface area, enhancing the sauce’s taste.
- Finely Grate the Parmesan – For instant melting, grate the parmesan cheese from a block using a microplane grater. This ensures a smooth, creamy consistency. If you buy pre-grated parmesan, I recommend running it through the food processor or the blender. You could also finely mince it with a chef’s knife.
Customize Your Sauce
While this Alfredo sauce is perfect on its own, you can add black pepper, salt, onion powder, or Italian seasoning to suit your taste.
For extra richness, consider mixing in an egg yolk, reminiscent of a Carbonara sauce.
Fresh parsley always makes a nice garnish on any creamy white sauce.
Storage Recommendations
Store any leftover Alfredo sauce in an airtight container in the refrigerator for optimal freshness. It’s best used within a few days to maintain its deliciousness.
How To Reheat Alfredo Sauce
To avoid separation, gently reheat your Alfredo sauce.
- Stovetop: Heat it over very low heat in a saucepan, stirring frequently until warmed through.
- Microwave: Use 50% power in 1-minute increments, stirring each time until heated.
- Super Hot Pasta: Add room temperature sauce to freshly drained, hot pasta—the residual heat will warm the sauce perfectly.
FAQs
This sauce shouldn’t need to be thinned, however it is easy to thin, if needed. Achieving the desired consistency is easy. To thin this sauce, simply add more heavy cream. You can also add small amounts of hot salted starchy pasta water. To do this, scoop out a cup of salted pasta water just before draining the pasta, and stir it into the sauce as needed to reach the desired thickness.
This sauce shouldn’t need to be thickened if made as directed, however there are additional ingredients to add if you want to amp up the creaminess. A spoonful of mascarpone, cream cheese, or sour cream will all work.
It is said that the original recipe came from Alfredo di Lelio who lived in Rome over 100 years ago. I struggle with how impressive this was, because the original version was simply butter and parmesan. That’s no different than how I used to make my “buttered noodles” when I was ten-years-old.
My version is definitely an American-style Alfredo sauce. A little garlic and some heavy cream definitely takes “buttered noodles” to a whole different level.

Equipment
Ingredients
- 4 tablespoons butter
- 4 cloves garlic finely minced or pressed
- 1 1/2 cups heavy cream divided
- 1 1/2 cups parmesan cheese finely grated
Instructions
- Add butter and garlic to a saute pan and heat over low heat. Allow to cook until the butter is infused with the garlic, about 5 minutes.
- Add 1 cup of heavy cream, stir, and allow to come to a simmer. Increase heat to medium, if needed. Cook for 5 minutes, stirring occasionally.
- Remove from heat and immediately add in parmesan cheese and remaining heavy cream. (Note: the parmesan will easily melt if it was finely grated from a block. If you used pre-grated cheese that is thicker, you may have to continue heating over low heat to get it to melt.) Stir to combine. It will take several minutes for the cheese to melt. It will look goopy at first (especially if you used pre-grated cheese) and then the sauce will be creamy and smooth. If sauce needs to be thinned, add additional heavy cream.
- To serve, toss with tossed pasta or use to cover vegetables.
Notes
- Quality ingredients. The higher quality ingredients you use, the better your sauce will be. Make sure the garlic is fresh and, if possible, grown locally. Kerrygold is my butter of choice, but there are so many great ones available. Be sure to buy real authentic parmesan cheese imported from Italy.
- Press the garlic. When garlic is minced through a garlic press instead of chopped, you expose the maximum amount of surface area. That means you’ll extract the most flavor from it.
- Grate the parmesan yourself using a microplane. You can certainly use shredded parmesan, but it will not melt properly due to the large size of the pieces and anything that has been added to the cheese to prevent sticking. I highly recommend grating from a block of cheese using a microplane grater. It will make the parmesan melt instantly.
- Reheating. This alfredo sauce will thicken as it cools. If it cools too much, it will get too thick. If it gets too hot, it will separate. The trick is to keep it just warm enough. This sauce must be reheated gently either on the stove over low heat, in the microwave on 50% or lower power, or by adding super hot, freshly drained pasta to your sauce.
- Substitutions. Many readers ask if whole milk (3-4%) or half and half (10-12% fat) can be used in place of heavy cream (38-40% fat). The answer is YES, although I don’t recommend it because you will have a thinner sauce. If you need to make a substitution and feel that the final sauce is too thin, you can always stir in a bit of mascarpone or cream cheese at the end to thicken it.

Im confused on how your Alfredo sauce has only 186 calories where as other recipes have 380 calories up to 670 calories. How is it yours made with the same exact stuff as there’s and yours has fewer calories than the others ?
Hi Wendy, I consider a serving size only about 1/4 cup. If you drown your pasta in alfredo sauce, you’ll be getting a ton more calories!
Hi Krissy. I just made this tonight and it was amazing definatly making this again
Glad you liked it! It’s a favorite in our house.
What’s the serving size ?
Hi Dayna, The alfredo sauce makes about 3 cups and I said that there were about 12 servings in the recipe which would put the serving size at about 1/4 each. I realize that is on the smallish side if you’re planning on making fettucine alfredo, but I wanted to give a smaller option in case someone was making the alfredo sauce to top veggies as a side dish instead. Hope that helps!
If you desire to make it with milk or half and half, simply sprinkle a Tbsp of Wondra flour into the garlic simmering in the butter. Whisk until the flour bubbles. Then stir in the milk (or half and half), Parmesan, and adjust the thickness accordingly with either more milk, or pasta cooking water. It’s not as rich, but your arteries will thank you. But of course, pasta with cream sauce is not the same as pasta al Fredo, which is just butter and parmesan.
This sauce is amazing! I am very picky about my Alfredo sauce and infusing the garlic in the butter makes all the difference in this recipe. My family requests that I make this multiple times a month!
We do 1 lb of penne pasta with the sauce. It could probably use a little extra sauce, I’ve never tried adding the saved pasta water so I’ll do that next time.
I had to triple the recipe, add mozzarella, salt and pepper, a bit of cajun and parsley at the end, and it still was only enough sauce for half a small box of noodles but this was really good my husband really liked it 🙂
What would you say is the perfect amount of noodles for this recipe? Making it for a soccer team and don’t want it to dry out
Hi Monica, Totally understand. And yes – too much pasta will just absorb the sauce. I think this recipe will work with about a pound of pasta, however I highly recommend grabbing at least a cup or so of the salted pasta water before you drain it. Once you add the pasta, add some of the water if it appears to thick. It won’t change the flavor.
Such an easy recipe. So glad it doesn’t call for cream cheese. I love cream cheese… but not in my alfredo sauce!
This is the best alfredo sauce recipe I’ve tried. So much flavor!!!
Disappointed in this sauce. After I added the hot pasta, the liquid in the sauce seemed to be absorbed by the pasta and I was left with basically “dry” fettuccini. I had already plated it when I realized this and it was too late to add more cream. Taste was ok though.
Hi Elizabeth, So sorry to hear that! Is it possible you used too much pasta and it wasn’t the sauce? I ask because I’ve done that before.
How much pasta should I use so that doesn’t hsppen
I think this recipe will work with about a pound of pasta, however I highly recommend grabbing at least a cup or so of the salted pasta water before you drain it. Once you add the pasta, add some of the water if it appears to thick. It won’t change the flavor.
How well does this keep in the fridge?
It will keep. You just have to reheat very gently.
If you are pregnant I suggest you not use as much garlic.
I just tried this recipe for the first time and it turned out great! This is the first time I’ve ever made homemade Alfredo sauce and it was a hit with my family! Bold flavor & creamy consistency!
So this was a great recipe, I tweaked it a little after I initially followed the recipe, I added a little salt and pepper to my taste and shredded about a cup or maybe a little more Asiago cheese along with the Parmesan cheese listed in the recipe. I always add a little extra cheese to about everything. Also, the sauce was thin, but I made a double batch and added approx., give or take, 1 tablespoon of corn starch a little at a time until it was thickened up. I used 1 bag of egg noodles And added them to the sauce when I was done and by the time the chicken was done about 10-15 minutes later, the sauce had soaked a lot into the noodles, but there was a lot left over In the pan as well. I will be making this again in the near future.
