I was the world’s pickiest eater as a child. There were literally just two foods I couldn’t get enough of – eggs (that hasn’t changed!) and Fettuccine Alfredo. Since I started eating low carb and gluten-free, I haven’t had fettuccine noodles in a long while. But, I do have a low carb keto Alfredo sauce recipe that I make all the time!
The most common way that I use low carb Alfredo sauce is over zoodles. I actually posted a different Zucchini Noodles Alfredo recipe last summer. That one had a lighter sauce, made by combining cream and unsweetened almond milk in addition to the Parmesan cheese. It’s delicious and still one of my favorites, but sometimes I crave something richer.
When I want a garlic Parmesan cream sauce that’s suuuuper creamy, I make this keto Alfredo sauce instead. It tastes so rich and indulgent – but still without the carbs. And if you’re keto, you’ll like this version better since there is no arrowroot powder or other thickener.
Making your own low carb Alfredo sauce is incredibly easy. You only need four ingredients and ten minutes!
I absolutely love garlic, so my keto Alfredo sauce has lots and lots of garlic. Have you ever heard that joke? “The only recipe that uses one clove of garlic is how to prepare one clove of garlic. Even then, use two.” I saw it on Facebook somewhere and have no idea who originally said it, but that’s totally me! So, my garlic Parmesan cream sauce has six cloves of garlic in it. Feel free to reduce the amount if you’re not as much of a fan as I am.
Traditional Alfredo sauce typically has nutmeg in it, but I kept it as an optional ingredient to keep it simple. Lately I’ve been making spices optional in recipes when I can, not because I don’t use them liberally myself, but just to offer flexibility when possible. I do recommend the nutmeg for that familiar flavor in your keto Alfredo sauce.
Speaking of flavor, you may want to add more salt at the end, to your taste. When you do this, keep in mind that the low carb Alfredo sauce will be more concentrated when tasting it plain. It will mellow out when you mix it with other ingredients, especially lightly sweet veggies, like zucchini noodles. For this reason, I recommend adding a little more salt than you may think is needed.
You can easily prepare low carb Alfredo sauce in advance and store it in the fridge. Just reheat on the stove when you are ready to use it! Microwaving can also work, but use medium power to avoid separation.
Like any Parmesan cream sauce, this one tends to thicken as it sits. If this happens, you can always thin it out with a little more cream as needed. It’s super simple to adjust the thickness to your liking!
I actually have some extra low carb Alfredo sauce in my fridge right now. I usually use it over veggie noodles or in casseroles. My ultimate favorite way to use this low carb cream sauce is a recipe coming up in a couple of weeks, so stay tuned for that!
In the meantime, I’m always looking for more ideas for keto Alfredo sauce. What are your favorite ways to use it?

Would this sauce be okay to use in a Crock Pot? I’m wanting to make a Tuscan chicken dish that requires Alfredo sauce, but the store bought have ingredients I don’t need. I was thinking to make it the night before and use it the next day in the Crock Pot. Please let me know what you think. Thank you!

Hi Mandi, Yes, absolutely! Just to clarify, I haven’t tried actually making the sauce in the Crock Pot so am not sure about that part, but once you have the sauce ready, you can definitely use it in any Crock Pot recipe. 🙂
