This keto cheese sauce will become a staple in your cooking repertoire as it is super versatile. It’s a quick and simple recipe and even Dan can make it! It can turn any boring old meat and three veg into keto heaven. This keto cheese sauce recipe has been one of our most popular recipes and we decided it was time to give it an update. In my opinion, this keto cheese sauce is better than any cheese sauce I have tried, including a version that would have flour in it. It is thick and creamy and extremely cheesy and is a great way to add some fat to lean meats and vegetables.

Keto cheese sauce
Making a traditional cheese sauce involves flour and milk, which are both out once on a ketogenic diet. Replacing milk with pure cream (heavy whipping cream) was a pretty straight forward option, but Erika needed to find something to thicken the sauce in place of the flour.
So she did some experimentation with other thickeners like coconut flour and xanthan gum, but didn’t like the texture of the finished product. She was looking for a smoother, silkier sauce. So what better to thicken this keto cheese sauce than cheese itself! The cream cheese and parmesan cheese give both body and flavour to this delicious sauce.
The great thing about making this sauce, compared to a more traditional version, is that you just pop everything into the saucepan and whisk. No need to be making a roux, whisking in the milk and then worrying about lumps. It is quick and pretty much foolproof. Personally, I think it tastes better than the original too.

Absolutely yummy poured on anything!!
So true! Thanks Michelle
Being in isolation I did not have any cream, so I put some coconut cream in the fridge for a bit then when chilled whiped it into a cream. I used this instead to make the cheese sauce. IT IS YUM.
Love this and so easy ?? On our cauliflower for dinner tonight
Great – so glad you enjoyed it Wendy!
Excellent , so tasty and so quick to make. Love love it.
Awesome! Thanks Leonie
Love this sauce. I use it for everything and it is so easy to make.
Thanks so much Sue. It’s so good.
Great tasting cheese sauce.
I would like to know if I can thicken it & what would I use?
You could add extra grated cheese to thicken it. A very small amount of xanthan gum may work also, but be careful with over doing it as it may go slimey.
We find the sauce thick enough as is though and have never thickened it
Most amazing Cheese Sauce – Thank You
Love this recipe! I make a 2 1/2 X the recipe as that’s how much cream cheese is in a packet. I freeze what I don’t use immediately. I use small sisters containers for this. Such an easy recipe to make, extremely versatile and SO delicious!!

Best cheese sauce EVER. I managed to save enough to put on the Tuna Mornay (your recipe) which is in the oven now. Thanks for sharing it. 🙂
Thank you so much Judy. I definitely agree, it is the best. Hope you enjoyed the Tuna Mornay as well.

This is delicious and better than the original
I agree Jeanette, it’s an awesome tasting cheese sauce.
What is pure cream, pouring?
It is heavy whipping cream. We call it pure cream in Australia.
No we don’t. Pure cream is runny and comes in the smaller blue container. Just made lasagna, it’s in the oven the cheese sauce looks great.
Sounds delicious.
Will this keep for a few days in the fridge?
Yes, it should keep well in the fridge for 2-3 days.
