It’s no secret that homemade sauces are better for you than jarred ones, but sometimes convenience wins. But it doesn’t get easier than this low carb alfredo sauce recipe. In less than 15 minutes, with only 5 ingredients, you’ll have a rich and creamy white sauce that’s super low in carbs and perfect to pour over top of shirataki noodles or hearts of palm pasta.
Other keto alfredo sauce recipes use cream cheese as a shortcut, which adds an extra 3 grams of carbohydrates per quarter cup. This ultra-low carb recipe uses egg yolks, whipping cream, and butter to create a thick, rich and creamy sauce.
How to make keto alfredo sauce
- Sauté butter and minced garlic. Add a pinch of nutmeg for extra flavor.
- Whisk the egg yolk into heavy whipping cream, then pour it into the garlic butter mixture.
- Cook while stirring for 5-10 minutes or until the sauce has thickened enough to coat the back of a spoon.
- Add parmesan cheese and noodles to the thick and creamy alfredo sauce.
- Stir in noodles. To make keto chicken alfredo, add sliced chicken.
Key ingredients & substitutions
- Butter – Use salted or unsalted butter; however, unsalted butter you can control the saltiness of the sauce. You can always add more salt at the end if it’s needed. Parmesan cheese also adds salty flavor to this keto alfredo sauce recipe.
- Garlic – If you can’t get your hands on fresh, jarred minced will work, but fresh garlic will have a much stronger flavor.
- Egg yolk – This sauce uses only egg yolks as a thickener for a rich and creamy sauce. But don’t throw out the egg whites. Save them for your next breakfast scramble or to make meringues!
- Heavy whipping cream – If you use a lighter dairy like half and half or milk, your sauce won’t have the same creaminess. Heavy whipping cream is the perfect thickness for a luxurious alfredo. And substituting with a nut milk (almond milk or coconut milk) won’t get your sauce thick and creamy.
- Parmesan cheese – A necessary ingredient in alfredo sauce; however, other hard cheeses like Parmigiano-Reggiano cheese, Pecorino Romano, Grana Padano or Pecorino can be used.
- Nutmeg – Just a small amount of nutmeg adds a warm and nutty flavor that complements this comforting chicken pasta, but it can be left out if you don’t have it.

Can this sauce break?
If so, why does that happen and can it be avoided?
Thank you in advance!
If it boils, it can break. Just have patience and heat it over medium low heat until it thickens the back of the spoon. It can take 5-10 minutes depending on your heat source.

Ketofocus Can You Use Egg Wraps ForThe Noodles. Thanks
Yes, that would work. You can use any keto noodle you would like.
This was the easiest and best tasting Alfredo Sauce. I just shredded chicken and added to the sauce no noodles at all. It was delicious. Thank you so much for this recipe.
