This creamy low carb Fettuccine Alfredo sauce is the ultimate homemade Parmesan cheese sauce for keto diets. Easy and yummy!

How many of you with “littles” order mac-and-cheese for them when you dine out? Raise your hand. Mine is up! Lol. Not only is the macaroni easy for smaller mouths to handle, but the cheese sauce is always a hit! Who doesn’t love cheese sauce? I know I do.

We grown-ups like our cheese sauce just as much as the “littles” – that’s why so many of us enjoy ordering Fetuccine Alfredo. Or we did before going low carb! Isn’t Fettuccine Alfredo just a grown-up version of mac-and-cheese with a creamy Parmesan cheese sauce?

You’ll be so happy to have this easy low carb recipe in your back pocket to pull out and dazzle your family. I promise!

How to Make Authentic Alfredo Sauce

An authentic Alfredo sauce recipe starts with a roux (a thickener for sauces); equal amounts of butter and flour are cooked at a low temperature until the mixture bubbles. Warmed milk is slowly added while stirring, to prevent lumps. This classic French sauce, bechamel, is the base for many cream sauces. The sauce is simmered gently until the taste of raw flour disappears. Adding just a touch of freshly ground nutmeg brings out a complexity of flavor.

To make this creamy sauce an Italian Alfredo sauce, just add Parmesan cheese and whisk until it melts. It’s that simple.

But this is a low carb recipe and it’s even easier to make!

Thick creamy Alfredo sauce, Parmesan cream sauce, dripping from a spoon over a filled jar of sauce on a cutting board. A wooden spoon sits to the left of the jar with parsley, onions, garlic and a pot in the background.

Since choosing our low carb life, I’ve had to find new ways of doing things and develop new recipes to replace old favorites. Low carb Alfredo sauce is completely possible and absolutely delicious. It doesn’t require much time to make and only 5 ingredients (plus salt and pepper)! It keeps beautifully in the fridge without separating. To reheat, warm it gently in a pot, stirring every few moments so it doesn’t burn, until warmed through. The end.

Creamy Low Carb Alfredo Sauce With Cream Cheese

This simple recipe for creamy low carb Alfredo sauce starts with butter and softened cream cheese. It sounds great already, right? I know. Since we’re skipping the roux (this is a gluten-free recipe), we need to find an alternate way to thicken the sauce – cream cheese!

Add heavy cream, little by little, alternating with freshly grated Parmesan. Make sure to use freshly grated Parmesan cheese from a block for the best flavor and ease in melting. The powdery grated Parmesan cheese from the deli didn’t melt for me.

Add more cream. Whisk a beaten egg yolk right to the pot to thicken and stabilize the sauce so it doesn’t separate. Finish with white pepper and just a touch of freshly grated nutmeg. Simmer very slowly for a few minutes until thickened and it coats the back of a spoon. It thickens further as it cools.

This is a delicious Parmesan cheese sauce for broccoli, chicken, cauliflower or any low carb or keto noodles.

    I don’t know what this tastes like with heavy cream… I’m sure AMAZING but I just followed the recipe but used 1% milk (I also added minced garlic)… and it was really, really good!! A little thin at first but thickened up nicely as it started to cool.

    Is it based on the entire recipe?
    ..the 1/3 cp serving?
    …or on so many tablespoons?

    Absolutely delicious and very easy to make!!! I halved the recipe but still used the whole egg yolk and it came out perfectly. I served it over “squoodles” (yellow squash noodles) and it perfectly complemented the meal of grilled salmon and endive, avocado salad with champagne vinaigrette. Your recipe bank is truly a treasure! Thank you so much.

      Hi Susan. I would not cook your chicken legs in this sauce. The yolk will probably cook and the fat in the cream cheese and heavy cream will probably separate out. It would be better to cook them separately. -Kim

    I am sure the ham/cheese casserole is good. I would really like one without ham. Your alfredo sauce has so many good comments and ingredients. You are a better judge than I. Do you think I could add other cheeses to make a cauliflower cheese casserole? You also mentioned if you bake your ham/cheese in the oven that it gets a litter watery from the cauliflower. I have just about had soup before (would be good though)………… Do you think the egg in your alfredo might make the sauce not break……..add cheddar………..pour over cauliflower??? I will keep trying……you are a good inspiration! thank you

      You don’t have to put the ham in it, Sue. I am unsure about the egg yolk. If the casserole goes into the oven, it may cook the egg? I was going to try it and chickened out. I used the other recipe instead, which is also the way I make my White Chicken Enchiladas. This is an awesome sauce, though. I would cook the cauliflower separate, mix with this sauce, top with your crunchy topping or cheese and place it under the broiler. I think that would be delicious. Nice talking to you. -Kim

    Do you think cheddar could be added to this to make cauliflower Mac and cheese? Trouble finding a recipe that won’t separate. Maybe the egg is the truck!!!

    Oh wow… phenomenal sauce! Added some minced garlic while melting the butter and cream cheese to increase the garlic flavour, a tad more Parmesan cheese, some minced parsley,
    and some Cajun seasoning to spice it up a bit. Sauteed a red pepper with some scallops and a couple fillets of white fish, in butter, and served it all over spaghetti squash. Will try it with chicken next time, but man was this awesome!!! Can’t believe this is considered Keto diet food, loved it!!!!!!!!

    This was so yummy! It didn’t taste like a low carb version at all. It was way better than any store bought Alfredo that I’ve ever bought.
    I wanted to add that I didn’t have any heavy cream on hand so using my immersion blender I blended equal parts milk and cottage cheese to total the amount of heavy cream it calls for. It worked great.

    Creamy Low Carb Alfredo sauce. This was really good! I am on a high protein low carb diet and I served this with chicken, sautéed Bella mushrooms and onions along with zuchinni noodles. The men in the house even said I could fix this again.
    That alone is high praise for anything that gets made for dinner or supper here.

    Made this sauce and ate it with zoodles tonight. Great flavor but I wish it were thicker. Followed the recipe (though I omitted nutmeg) and mine was so thin! I kept hoping it would thicken if we let it sit, but no such luck. Oh well! Something to keep in mind next time I make it.

      Hi Alecia, let it cook a little but longer. It is a nice thick sauce. Zucchini noodles can be watery and maybe it watered the sauce down? I had it on spaghetti squash and it was super thick. Cook it until it leaves a track on the spoon like in the pictures. -Kim

    So many recipes for cauliflower Mac n cheese. I have tried, but leftovers separate and get grainy. You mention using an egg in this…..it is the whole egg? Do you think this would convert to a Mac/cheese sauce with additional cheeses?? Appreciate any suggestions.

      Hi Sue. The sauce calls for an egg yolk, not a whole egg. Yes, this works well for spaghetti squash, broccoli, and cauliflower. Make sure to steam the vegetable well and drain before adding it to the pan with the sauce. You can add ham or bacon if you wish. -Kim

      Not at all, Brandy. The egg yolk just makes it richer and helps thicken or emulsify the sauce so it doesn’t separate. -Kim

    I’m sorry, I have a bit of a stupid question. 2oz of Parmesan is 1/4 cup, but your recipe says to add 1/4 of the parm after 1/4 of the cream, then alternate the two. Am I missing something, or do you need a full cup of parm too?

      Great question. I hand grated my Parmesan cheese on a microplane grater which fluffs it up and measures “bigger” than pre-grated cheese from the store. The pre-grated from the store doesn’t like to melt as well, so go slowly while adding it. It likes to clump up. Make sure it melts before adding more cheese. Does this help? Let me know. -Kim

      The egg yolk helps the sauce stay together without the use of cornstarch or flour (typically used) and thickens it. If you are going to use the sauce right away, you can leave it out. I tend to make a double batch and the egg yolk helps me reheat the sauce without having it “break” (separate) on me. -Kim
